In short

Escitalopram and sertraline are the two antidepressants we reach for first, with few drug interactions, for depression, anxiety and OCD. We usually lean toward sertraline because it has more titration steps and is broken down by several enzymes, while escitalopram depends on 3A4 and 2C19, so fast or slow metabolizers can do badly. Start low (2.5 mg for a week if there is no rush), and expect a minimum effective dose of 5 to 10 mg.

When we reach for it

  1. The first two antidepressants anyone should use are sertraline or escitalopram. Both have relatively few interactions, which matters even in young patients who may need another medication down the line.

    “to me, the first two antidepressants anyone should be using to me are always, it's either sertraline or escitalopram”

    “I think they're both fine choices because on top of the things that you just mentioned, they tend to have, relatively speaking, less interactions of other medications. Even if someone's young, you never know if they're going to have to add another medication for some kind of a new medical condition down the line”

  2. One of our four first-line antidepressants, alongside Zoloft.

    “I typically consider there to be four first line in how I practice. I have pretty much four first line antidepressants that I use. As you said, it's Zoloft and Lexapro. If I'm choosing an SSRI, how I choose between those depends on how I'm feeling that day”

  3. Zoloft or Lexapro tend to have fewer med-med interactions, but really any SSRI is fine. We avoid Paxil because it tends to cause weight gain.

    “I like to use Zoloft or Lexapro because they tend to have less med-med interactions, but really any SSRI is fine. I avoid Paxil because Paxil tends to cause weight gain”

Dosing and titration

  1. The minimum effective dose for the average patient is somewhere between 5 and 10 mg.

    “Zoloft 50 milligrams is my minimum effective dose for the average patient. And then Lexapro, I have somewhere between 5 and 10 as the minimum effective dose”

  2. If there is no rush, start 2.5 mg for one week, then 5 mg. Many patients have a harder time going from 5 straight to 10.

    “Lexapro, if I'm not in any sort of rush, I usually do the same thing with a 5 milligram. So I'll say take 2.5 for one week and then go up to 5. And that's just because I've had a lot of patients have more difficulty tolerating Lexapro if I go 5 to 10”

  3. Another approach gets patients to 10 mg fairly fast, partly because 5 mg tablets can be hard to get from local pharmacies.

    “I get them to 10 pretty fast. It's just it's almost psychological on my part in that, you know, it's I've had problems with getting five milligram tablets from pharmacies locally. So often I don't have that option”

  4. It has only four titration steps, which feels limiting psychologically and physiologically.

    “it only has four titration steps, unfortunately, which I don't like. I like to have more steps. I think that works psychologically. Physiologically”

Compared with others

  1. We generally prefer sertraline: four steps up to 100 and four more to 200, rather than two steps to 10 and two to 20, and somewhat fewer interactions.

    “Zoloft and Lexapro are my favorites. I generally prefer Zoloft. Why? Because more room for titration. You have four steps up to 100 and four steps up to 200 rather than two steps up to 10 and two steps up to 20. It's just a little easier to work with in that sense and tends to have less medication interactions”

  2. Escitalopram is broken down mainly by 3A4 and 2C19, and 2C19 has many variants, while sertraline goes through several pathways. Ultra-slow or ultra-fast metabolizers have a really bad response to escitalopram more often than to sertraline.

    “Sertraline has a bunch of different sips that metabolize it. For patients that have ultra-slow or ultra-fast metabolization of whatever escitalopram is metabolized by, you will get patients who have really bad response to escitalopram more often than with sertraline”

    “Zoloft is highly variable in its metabolism, whereas Lexapro is really just broken down by 3A4 and 2C19. I always zone out once I start hearing the SIP stuff, but this is pretty simple. If someone has 2C19, there's a lot of variants”

  3. Being the purest SSRI does not mean the fewest side effects. Sertraline is a little better tolerated overall, and some patients tolerate citalopram better than escitalopram, against what we are taught.

    “I find that sertraline has less side effects overall and sertraline is a little bit better tolerated even though it is the quote unquote most pure SSRI. I've had patients who tolerate citalopram better than escitalopram which goes against what we're taught”

  4. Escitalopram is the active enantiomer, so there is little point to citalopram, except that citalopram prolongs QTc more. On the FDA data, escitalopram up to 20 mg did not significantly increase QTc.

    “I never use Celexa citalopram. There is no point. The active enantiomer is Lexapro, okay? There is no point. Well, there's one point. If you want to prolong someone's QTC, you should use Celexa over Lexapro. If you actually look at the FDA data, Lexapro up to its... 20 milligram dose did not significantly increase QTC”

Pearls

  1. Keep an open mind: some patients who felt terrible on escitalopram, with bad sexual side effects, do great on citalopram.

    “she's seen a ton of patients that had tried Lexapro in the past and had completely different response to Celexa. She brought up one case that like the patient felt super uncomfortable on Lexapro, had terrible sexual side effects, and then Celexa worked great for them”

  2. When the same drug works differently at different times, it is usually because a lot more is going on in a person's life than one medication.

    “a lot of people's different responses at different times to the same medications, and you see this all the time with many different medications, It's more because there's a lot more going on with patients, with people than a single medication”
