In short

Lithium is the gold-standard mood stabilizer, one of the two drugs shown to reduce suicidality, and underused because it scares people. Most of that fear comes from inpatient-era manic dosing: start low, titrate slowly with the patient's hand on the knob, accept lower levels outside acute mania, and treat the patient rather than the level. Monitor kidney, thyroid and calcium, counsel on salt, hydration, NSAIDs and blood pressure drugs, and use it across the mood spectrum, including as an augmenter in depression.

When we reach for it

  1. Lithium is the gold standard, the classic mood stabilizer.

    “Lamotrigine. which is the weakest, but also probably the best tolerated. We have lithium, which is the gold standard, the classic. And we have Depakote. Works great. There are some problems with it, especially with both male and female fertility”
    22:51The Best Bipolar Medication Review From The Best Bipolar ExpertJan 2025
  2. Lithium for bipolar disorder and clozapine for schizophrenia are the two medications with evidence for reducing suicidality. When suicidal ideation comes from bipolar disorder, don't forget lithium.

    “Those are the two medications that have shown to have evidence in reducing suicidality. Lithium for bipolar and clozapine for schizophrenic patients has shown to actually reduce suicidality”

  3. Low-dose lithium works across the whole mood spectrum. It is least appreciated and most valuable in the middle of the spectrum, sometimes alongside social rhythm therapy or lamotrigine.

    “Where I think it's least appreciated and most valuable is in the middle of this mood spectrum, where sometimes this might be along with modified social rhythm therapy, for example, or Lamotrigine”
    6:34Dr. Jim Phelps’ Bipolar Treatment Tier List: Lessons from 30+ Years in PsychiatryJul 2026Guest episode
  4. When bipolarity is uncertain, simplified social rhythm therapy is the first mood stabilizer, then lamotrigine and low-dose lithium.

    “simplified social rhythm therapy is my number one mood stabilizer and then lamotrigine and low-dose lithium”

  5. It is one of the mood stabilizers with antidepressant efficacy, along with lamotrigine and quetiapine.

    “Which are the MSAEs? This I thought was where you were going with the Ls. Three Ls and a Q for the mood stabilizers with antidepressant efficacy. I missed trazodone. Lithium, lamotrigine, trazodone, and we have to put quetiapine on there”
    50:45Dr. Jim Phelps’ Bipolar Treatment Tier List: Lessons from 30+ Years in PsychiatryJul 2026Guest episode
  6. The idealistic lithium patient has euphoric mania with intermittent episodes of depression. Depakote has more evidence in rapid cycling and mixed episodes.

    “the idealistic bipolar patient, the patient with euphoric mania and then with intermittent episodes of depression. That is considered the idealistic lithium patient. Depakote has some evidence with rapid cycling. It has some evidence with mixed episodes”
    42:14Mood Stabilizers for Bipolar Disorder: Lithium, Lamotrigine, Depakote & MoreJul 2026
  7. For acute mania, one first-line combination is lithium plus lurasidone (and gabapentin): lurasidone works quickly at low doses, and lithium is the most effective long term.

    “It's lithium. Okay. And... It's latuda, and then it's gabapentin. And why? Because I find latuda to be effective quickly and at low doses. Lithium is most effective long-term”
    44:48The Best Bipolar Medication Review From The Best Bipolar ExpertJan 2025
  8. In any schizophrenia spectrum disorder with a hint of mood problems on either pole, add a mood stabilizer before reaching for a second antipsychotic. Depakote first for agitation and impulsivity; for anything else, lithium, lithium, lithium (lamotrigine is the other option).

    “if you have any schizophrenia spectrum disorder and you have any hint of mood problems on either pole, add a mood stabilizer. If it's agitation, probably try Depakote first along with impulsivity. That may help. And if it's anything else, lithium, lithium, lithium”

  9. Lithium started postpartum has the strongest evidence for preventing postpartum psychosis, which is highly linked to bipolar disorder.

    “Lithium-initiated postpartum has the strongest evidence for the prevention of postpartum psychosis. And in postpartum psychosis, highly linked to bipolar disorders”

In depression

  1. Lithium has evidence as an augmenting agent in unipolar depression. Some clear-cut but severe unipolar depressions probably have something a little more bipolar in them, and Europe is much more willing than the US to add lithium to what looks like unipolar depression.

    “lithium has evidence for unipolar depression as an augmenting agent, right? So there's probably some, in my opinion, there's probably some percentage of people that have just a really clear-cut unipolar but severe depression, that there's something in there that's a little bit more bipolar”

    16:59The Best Bipolar Medication Review From The Best Bipolar ExpertJan 2025
  2. When a patient has recurrent mood episodes and many failed medication trials, make sure there has been a mood stabilizer trial at some point.

    “But since learning about that, whenever I've heard a patient has had recurrent mood episodes and I see a lot of the previous medication trials haven't worked, I really make sure that there's been a mood stabilizer trial at some point”
    28:59How to Diagnose Bipolar Disorder: The Interview Framework That Beats Screening QuestionsFeb 2026
  3. For treatment-resistant depression the best evidence goes to ECT, TMS, antipsychotics (aripiprazole most of all), lithium, thyroid supplementation, and ketamine or esketamine.

    “The best evidence goes to ECT, TMS, TMS. antipsychotics, particularly aripiprazole has the best evidence and the biggest effect size, lithium, thyroid supplement, and the ketamines, esketamine and ketamine. So those would be our top line interventions”

Dosing and titration

  1. Low-dose titration: start at 150 mg and go up 150 mg every four to seven days until something good happens, something bad happens (then go back down one step), or you reach 600 mg a day, and then check a level.

    “Starting with 150 milligrams, because that's the smallest dose we can engineer, and going up by 150 milligram steps every four to seven days and nights. Until something good happens, something bad happens, go back down one step, or you get to 600 milligrams daily and then check a level”
    4:07Dr. Jim Phelps’ Bipolar Treatment Tier List: Lessons from 30+ Years in PsychiatryJul 2026Guest episode
  2. Or start around 450 mg nightly of the ER. Starting at 900 mg, and many of the feared side effects, belong to the older inpatient era; that is too high for outpatients.

    “So the first thing that I would say about lithium is that you should try it at And around 450 milligrams nightly on an ER”
    18:26Mood Stabilizers for Bipolar Disorder: Lithium, Lamotrigine, Depakote & MoreJul 2026
    Also said in 1 more episode
    “A lot of the side effects and problems are emphasized with lithium are, in my opinion, from the older era of prescribing, which is based on inpatient. And that goes the same for the practice of starting at around 900 milligrams total daily dose. Too high. Too high for the outpatient population”
    18:05Mood Stabilizers for Bipolar Disorder: Lithium, Lamotrigine, Depakote & MoreJul 2026
  3. There is a narrow therapeutic window only when treating acute mania. In lower acuity conditions and long term, lower doses can bring clinical improvement, even if it is not perfect.

    “There is not a narrow therapeutic window for lithium. There's a narrow therapeutic window for lithium if we're treating acute mania. Okay, that's the key. That's the key. So when it comes to treating lower acuity conditions or in the long term, you can see clinical improvement, even if it's not perfect, with lower doses of lithium”
    19:47Mood Stabilizers for Bipolar Disorder: Lithium, Lamotrigine, Depakote & MoreJul 2026
  4. For adjunctive lithium or mild bipolar disorder, levels of 0.4 to 0.7 are fine. The traditional target of about 0.75 comes from literature on severe, hospitalized bipolar I.

    “Adjunctive treatment with lithium or for mild bipolar, anything in the 0.4 to 0.7 range is actually fine. You don't have to do the old manic dosing”
    34:03Mood Stabilizers for Bipolar Disorder: Lithium, Lamotrigine, Depakote & MoreJul 2026
    Also said in 1 more episode
    “Now, the level, historically, we try to target around 0.75. Personally, I would say that the level of lithium that we have in the literature is geared more towards control of severe bipolar disorders, bipolar 1 disorder, hospitalized bipolar disorders”
    27:07The Best Bipolar Medication Review From The Best Bipolar ExpertJan 2025
  5. Maintenance is considered 0.6 to 0.8; 0.8 to 1.2 is for a patient who is actively manic. Once the mania breaks, bring the dose down: nobody should be stuck at 1.1 as maintenance without a clinical reason.

    “maintenance is considered the 0.6 to 0.8 range. 0.8 to 1.2 is considered acute mania. Now that doesn't mean that you're protecting mania. That means the patient is actively manic. That's when you push up to 0.8 to 1.2”

    Also said in 1 more episode
    “Actively manic patient. The mania breaks. They're doing better. Bring down the dose. The patient should not be stuck unless you have clinical reasons to do this. Patient shouldn't be on 1.1 as a maintenance dose”
    34:44Mood Stabilizers for Bipolar Disorder: Lithium, Lamotrigine, Depakote & MoreJul 2026
  6. It takes at least two weeks to start working, and in an acute state it will not kick in until the dose is adequate. Set expectations; wanting instant gratification is part of why clinicians and patients skip mood stabilizers.

    “the onset of effect of lithium takes at least two weeks most of the time. So that's the problem with the mood stabilizers. I think that's why a lot of people don't use them today, because they want instant gratification as a clinician and a patient. You have to set expectations”
    35:31Mood Stabilizers for Bipolar Disorder: Lithium, Lamotrigine, Depakote & MoreJul 2026
    Also said in 1 more episode
    “when you switch to lithium, you got to remember that if someone is in an acute state, uh, It takes up to two weeks to really start kicking in, and it's really not going to kick in unless you get to an adequate dose”
    32:17The Best Bipolar Medication Review From The Best Bipolar ExpertJan 2025
  7. In a low-resource clinic where many patients refuse or cannot get labs, we will titrate to around 750 or even 900 mg, guided by reported adverse effects, before the first level.

    “I will titrate Up to the range of around 750 or even 900 depending on the reported adverse effects even without the first lab draw. But this is because I'm in a low resource clinic where despite my efforts many people will refuse or be unable to get lab draws”
    20:26Mood Stabilizers for Bipolar Disorder: Lithium, Lamotrigine, Depakote & MoreJul 2026

Monitoring

  1. Treat the patient, not the level. Go by long-term clinical stability, and look carefully at sleep patterns.

    “for lithium levels, treat the patient, not the level. So go off of your actual long-term clinical stability or lack of stability. Look at the sleep patterns carefully”
    33:45Mood Stabilizers for Bipolar Disorder: Lithium, Lamotrigine, Depakote & MoreJul 2026
  2. The labs look at kidney function, thyroid function and calcium. Within the first month, check a lithium level, thyroid panel, CBC and comprehensive metabolic panel.

    “We're looking for kidney function, right? We're looking for thyroid function, and we're looking for calcium levels. That's the simplistic way of saying it. Those are the main ones that we're going to see being impacted on labs”
    26:23Mood Stabilizers for Bipolar Disorder: Lithium, Lamotrigine, Depakote & MoreJul 2026
    Also said in 1 more episode
    “within the first month, I want them to get labs. And I want to check the lithium level. I want to check the thyroid panel. I want to check the combined blood count. And I want to check the comprehensive metabolic panel”
    29:35The Best Bipolar Medication Review From The Best Bipolar ExpertJan 2025
  3. With low-dose lithium you do not need the same lab schedule as higher doses, and you would not expect the same kidney dysfunction.

    “with low dose lithium we don't need to be monitoring all labs or we don't need to have the same lab monitoring schedule that we have with higher dose lithium. We wouldn't expect the same level of kidney dysfunction”
    15:39Antidepressant Tier List: Psychiatrists Rank Depression Medications for MDDMay 2026
  4. If you know a patient will never follow up for labs, lithium is probably not the medication. Still, we will give up to 450 or maybe 600 mg long term without labs to a competent patient who understands the risks.

    “if you have a patient that absolutely you know is never going to follow up for labs, lithium probably is not the medication, the correct medication”
    21:07Mood Stabilizers for Bipolar Disorder: Lithium, Lamotrigine, Depakote & MoreJul 2026
    Also said in 1 more episode
    “I'm willing to give up to 450 or maybe even 600 of lithium without labs in the long run if the patient is competent, has the capacity to understand the risks that they're taking on”
    21:39Mood Stabilizers for Bipolar Disorder: Lithium, Lamotrigine, Depakote & MoreJul 2026
  5. The ER does not have to be given twice a day; you can dose it all at once. But level studies used immediate release two or three times a day, drawn 12 hours after a dose and before the next, so time your draws accordingly.

    “But just know that you don't have to do the ER twice a day. You can dose it all once in the daytime. But you're going to have to time your lithium level draws accordingly, which can be a bit of a challenge”
    18:59Mood Stabilizers for Bipolar Disorder: Lithium, Lamotrigine, Depakote & MoreJul 2026
    Also said in 1 more episode
    “the studies of the lithium levels are usually based on the immediate release, dosed two times or three times a day. You always draw 12 hours after the dose, but before the next one”
    28:43The Best Bipolar Medication Review From The Best Bipolar ExpertJan 2025
  6. To tell true diabetes insipidus from simple lithium polyuria, you are supposed to do a 24-hour urine collection.

    “The way you're actually supposed to tell if this is really happening or if it's just simple polyuria from lithium, which is, by the way, the most common adverse effect of lithium, is that you're actually supposed to do a 24-hour urine collection study”
    32:32Mood Stabilizers for Bipolar Disorder: Lithium, Lamotrigine, Depakote & MoreJul 2026
  7. A slightly higher white count from demargination is fine and non-pathological.

    “Now, you can also see demargination of the white blood cells and a little higher white blood cell count on lithium. That is fine. Don't worry about that. It's non-pathological”
    26:35Mood Stabilizers for Bipolar Disorder: Lithium, Lamotrigine, Depakote & MoreJul 2026
  8. Ordering labs is not a big deal: make a lab requisition form and give it to the patient.

    “Ordering labs is not as big a deal. It's not as time intensive as I once imagined. It's not like you need to go on a website and fax things and all these things. You can make a lab requisition form and give it to the patient”
    33:17Mood Stabilizers for Bipolar Disorder: Lithium, Lamotrigine, Depakote & MoreJul 2026

Side effects and safety

  1. The two major adverse effects in practice are thirst with increased urination (more common, and different from the rarer diabetes insipidus) and acne. Increased urine can alarm clinicians who are new to lithium.

    “What are the two major adverse effects in my experience with lithium? It is thirst combined with increased urination. Not the same as diabetes insipidus. That can happen. It's more rare. And then acne”
    28:21Mood Stabilizers for Bipolar Disorder: Lithium, Lamotrigine, Depakote & MoreJul 2026
    Also said in 1 more episode
    “it's actually very common for people to notice increased urine production with lithium. And if you're not experienced with lithium, this can be a little bit concerning”
    26:32The Best Bipolar Medication Review From The Best Bipolar ExpertJan 2025
  2. Dosed at the minimum effective level, it does not cause much weight gain. Acne, if it happens, has no great fix.

    “if you're dosing it appropriately and at the minimum effective, then you're not going to see much weight gain. But acne, unfortunately, if it happens, there's not really much you can do about it”
    28:58Mood Stabilizers for Bipolar Disorder: Lithium, Lamotrigine, Depakote & MoreJul 2026
  3. At non-manic doses, the 20-year risk of renal dysfunction is much tinier than people realize, and renal damage is extremely unlikely as long as you watch for NSAIDs and antihypertensives and check levels.

    “the 20-year actual risk for renal dysfunction when you're not using it at the manic doses is much, much tinier than everyone is aware of”
    27:15Mood Stabilizers for Bipolar Disorder: Lithium, Lamotrigine, Depakote & MoreJul 2026
    Also said in 1 more episode
    “The probability of doing renal damage with this is extremely low unless you're not watching out for nonsteroidals and antihypertensives. I mean, you do need to check the levels. And of course, that means you need to get blood tests”
    4:47Dr. Jim Phelps’ Bipolar Treatment Tier List: Lessons from 30+ Years in PsychiatryJul 2026Guest episode
  4. It is a salt. Too much salt lowers the level and too little raises it; dehydration raises it and overhydration washes it out; NSAIDs hold lithium in and can make it toxic.

    “So make sure you talk to your patient about hydration, right? Salt intake because taking in too much salt will lower the lithium level and not taking in enough salt will raise the lithium level. Being dehydrated will raise the lithium level and over hydrating will wash out the lithium”
    22:23Mood Stabilizers for Bipolar Disorder: Lithium, Lamotrigine, Depakote & MoreJul 2026
    Also said in 1 more episode
    “since it's a salt, you eat too much salt, you're going to kick the lithium out. You eat too little salt, you're going to hold more lithium in. You take any NSAID, it's going to hold the lithium in. It can even make it go toxic if you take a lot of it”
    27:43The Best Bipolar Medication Review From The Best Bipolar ExpertJan 2025
  5. Quite a few blood pressure medications interfere with lithium. Tell patients to let whoever prescribes their blood pressure medication know they are on lithium.

    “when it comes to the blood pressure medications, the ones that interfere with lithium, there's actually quite a few. And what I just say is you need to make sure you tell your primary care doctor or whoever prescribes you a blood pressure medication that you're on lithium”
    23:04Mood Stabilizers for Bipolar Disorder: Lithium, Lamotrigine, Depakote & MoreJul 2026
  6. High lithium levels guarantee a decline in kidney function. High Depakote levels do not guarantee end-organ damage; there you watch for low platelets and hyperammonemia.

    “high levels of lithium guarantee you decline of kidney function. High levels of Depakote do not guarantee any end-organ dysfunction necessarily. You've got to monitor for it, but it's not a guarantee. You're pretty much looking out for a low platelet issue. Hyperammonemia, the liver producing too much ammonia”
    38:52Mood Stabilizers for Bipolar Disorder: Lithium, Lamotrigine, Depakote & MoreJul 2026
  7. Spironolactone is an option for acne in a very compliant patient, but it raises lithium levels: check labs before and after starting it.

    “spironolactone, which we know increases lithium levels. So it is an option if you have a very compliant patient that you can check labs, check labs before the dose, the start of the spironolactone, check labs after the start of the spironolactone dose”
    30:19Mood Stabilizers for Bipolar Disorder: Lithium, Lamotrigine, Depakote & MoreJul 2026
  8. The combination is not completely contraindicated if the patient fully understands the risks, is well monitored, has good family support and you keep a close eye on them.

    “But that said, it's not 1000% contraindicated. And if the patient fully understands the risks, they're well monitored, they've got good family support, you've got a close eye on them, it's not completely contraindicated”
    30:50Mood Stabilizers for Bipolar Disorder: Lithium, Lamotrigine, Depakote & MoreJul 2026
  9. Amiloride has been written about in small case studies as reducing lithium's kidney damage and polyuria.

    “there is amiloride. Technically, that has been written about and has some small case studies about where you add that with lithium and it reduces the amount of damage that lithium can do to the kidneys and also reduces the polyuria”
    31:47Mood Stabilizers for Bipolar Disorder: Lithium, Lamotrigine, Depakote & MoreJul 2026

Pitfalls

  1. Lithium scares people, and its prescription rate has gone down. It is scary the first time: all those labs and side effects to discuss.

    “it's only 20% of patients who are taking it, 50% are taking Antidepressants, 60% are taking antipsychotics, 20% are taking lithium. And yet we think that it's one of the best tools that we have”

    “They're not used enough. People don't give it enough of a chance. People aren't using it enough as an add-on in certain conditions. But lithium in particular, I think, scares people. And as a result, the prescription rate has gone down”
    10:06Mood Stabilizers for Bipolar Disorder: Lithium, Lamotrigine, Depakote & MoreJul 2026
    “I think it is scary prescribing lithium. It is your first time. You're like, oh, my God. I'm going to have to talk about all these labs and all these side effects”
    10:35Mood Stabilizers for Bipolar Disorder: Lithium, Lamotrigine, Depakote & MoreJul 2026
  2. Be very careful when lowering it. Abrupt lowering or stopping lithium may even induce mania rather than simply unmask it.

    “Be very careful when you lower lithium though. Among the mood stabilizers, abrupt lowering of lithium or stopping the lithium may be more likely to even induce mania rather than simply unmask it”
    35:16Mood Stabilizers for Bipolar Disorder: Lithium, Lamotrigine, Depakote & MoreJul 2026
  3. Consider avoiding lithium in people with genuine migraines (not just headaches); it seems to worsen them in a lot of people.

    “we might actually want to avoid lithium in people with genuine migraines. Not just headaches, migraines. Because it does seem to likely worsen the migraines in a lot of people”
    41:35Mood Stabilizers for Bipolar Disorder: Lithium, Lamotrigine, Depakote & MoreJul 2026

Talking to patients

  1. Pitch it as "the second you get a side effect, we go back down to the lower dose," and let the patient keep a hand on the knob. That makes a huge difference.

    “when you pitch it to a patient as the second you get a side effect, we're going to go back down to the lower dose. Whoa, what a difference that makes”

    5:16Dr. Jim Phelps’ Bipolar Treatment Tier List: Lessons from 30+ Years in PsychiatryJul 2026Guest episode
  2. Say it plainly: we don't do labs because this medication is unsafe; the labs are what make it extra safe.

    “I literally say to the patients, like the way I think about it is we don't do labs because this medication is unsafe. It's because we're doing this labs, this medication is extra safe”
    26:08Mood Stabilizers for Bipolar Disorder: Lithium, Lamotrigine, Depakote & MoreJul 2026
  3. A decline in kidney function is not renal failure. Given the choice of 30% worse kidney function or 30% less brain function over 20 years, take the better brain every time.

    “even if you have guaranteed decline in renal function, that is not the same as renal failure, okay? And if you told me that over the next 20 years, I had the choice between 30% worse kidney function and 30% less brain function, I'll tell you this. I'm going to take the better brain function every single time”
    27:27Mood Stabilizers for Bipolar Disorder: Lithium, Lamotrigine, Depakote & MoreJul 2026

    “dosed adequately it's a salt and it's processed by the kidneys. And therefore you probably are buying good brain in the longterm for some kidney function decrease in the longterm. And so there's that and there's problems with thyroid potential effects as well”
    25:30The Best Bipolar Medication Review From The Best Bipolar ExpertJan 2025
  4. Keep hydration advice simple: keep it stable, do not get too dehydrated, and do not change your water intake on your own; bring up any changes at the next visit.

    “You kind of just counsel patients, try to keep your hydration levels stable. Don't let yourself get too dehydrated”
    23:49Mood Stabilizers for Bipolar Disorder: Lithium, Lamotrigine, Depakote & MoreJul 2026
    Also said in 1 more episode
    “Sometimes with all this talk about hydration, when you first prescribe the lithium, people take it upon themselves to actively change their amount of water intake. I think I want to be clear to patients and say, you don't need to change what you're doing, but talk about any changes you notice at the next visit”
    29:41Mood Stabilizers for Bipolar Disorder: Lithium, Lamotrigine, Depakote & MoreJul 2026
  5. Walk through a one-page lithium sheet with the patient on a shared screen, especially the first few times you prescribe it.

    “I made a little page sheet that I share with the patient. And what I would do the first few times I prescribed lithium, and I still do this with patients that I feel like need to hear it. I share my screen and I walk through the, it's a Google Doc”
    24:10Mood Stabilizers for Bipolar Disorder: Lithium, Lamotrigine, Depakote & MoreJul 2026
  6. There is enough evidence to at least mention that lithium seems to help prevent dementia, especially in bipolar disorder.

    “I do think there's enough evidence so far to at least mention that this seems to be something that is a positive effect of lithium in preventing dementia. Especially in bipolar disorders”
    37:06Mood Stabilizers for Bipolar Disorder: Lithium, Lamotrigine, Depakote & MoreJul 2026
  7. Describe what you are seeing, give options within certain parameters, and stay open to updating your formulation. If a patient does not want to accept lithium's risks, do not push it; move on to the next choice.

    “You need to be open to updating your formulation. And like I said, working with the patient and describing what you're seeing and then giving them the options within certain parameters”

Compared with others

  1. Many people can take a lower daily dose of lithium alongside 200 of lamotrigine, which is much more tolerable than lithium alone.

    “A lot of people can get away with having a lower daily dose of lithium if they're on their 200 of lamotrigine. And then it'll be much more tolerable than trying to do just the lithium, for example”

  2. Is quetiapine better in the long run than lithium plus lamotrigine? We do not think so, though it has not been studied head to head.

    “is it actually better in the long run than let's say lithium plus lamotrigine? I don't think so. But, you know, they don't study that kind of thing head to head”

  3. Lithium orotate has almost no rigorous data, but it is really important to understand.

Pearls

  1. Lithium is one of the only psychiatric medications that regulates circadian rhythm. The closest we have come to bipolar genes are the clock genes, and lithium normalizes their expression.

    “lithium is one of the only psych meds that regulates the circadian rhythm the genes for bipolar the closest we've come to finding the genes for bipolar is linking them to the clock genes that regulate the circadian rhythm. And we know that lithium normalizes the expression of those clock genes”

  2. The low-dose approach makes lithium safer for you and your patients, and works like exposure therapy for prescribing it.

    “by using this other, this low-dose approach that I just described, it makes it safer for you, for your patients, and gives you the opportunity. It's like exposure therapy for using lithium”

  3. Lithium response is one of the validators that separates bipolar disorder from schizophrenia: give it to a bipolar patient and they get better; give it to a patient with schizophrenia and nothing really happens.

    “You give lithium to a bipolar disorder patient, they get better. You give lithium to a patient with schizophrenia and nothing really happens. And so you have to look across validators”

Earlier we said

Older episodes that put it differently. The points above are the newer view.

  1. We used to start lithium at a dose tolerable for outpatients of usually 450 to 600 mg, and as much as 900 mg, before calling a 900 mg start too high for outpatients.

    “I start the lithium. We get it to kind of a reasonable dose that can be tolerated in outpatient, usually 450 to 600, as much as 900 to start”
