I also use this strategy when starting bupropion in a patient with bipolar depression. Using the instant release bupropion, I’ll start at 75 mg per day and raise the daily dosage by 75 mg each week until I reach the target dose, and then switch to an extended-release version. I’ve found that this risk is significantly improved when I dose bupropion low and slow in patients with anxiety. Likewise, the risk of “agitation” with bupropion is similar to that with other second-generation antidepressants. 3 All antidepressants can cause anxiety, and they do in about 1 in 10 depressed patients. Yes it can, but the rate of anxiety as a side effect to bupropion are about the same as that of other antidepressants, according to several analyses of controlled FDA-registration trials. 1 A separate study from 2018 of over 5,000 elderly patients with new onset seizures found that escitalopram (Lexapro) and citalopram (Celexa) had the highest seizure risk, while the risk for bupropion was about the same as the other antidepressants they looked at. In a meta-analysis of 164 articles from 2018, it was clomipramine that came out with the highest seizure risk, and bupropion was not even at the top. With the SR, XL, Aplenzin, and Forfivo varieties, the risk of seizures has gone down. It’s likely that the instant release version does, because the risk is dose-dependent so when it’s dosed three times a day patients might accidentally take their tablets too close together, raising the blood level and the seizure risk. Myth #1: Bupropion is the antidepressant with the highest risk of seizures Bupropion had lost ground, and never regained it. By that time, Prozac (fluoxetine) had already come out in 1987 and was rapidly becoming one of the biggest blockbusters in psychiatry. It was withdrawn from the market soon after, and rereleased in 1989 with a lower maximum dosage: 450 mg per day instead of 600mg per day. Released in 1985, it soon became associated with an alarming rate of seizures, particularly in patients with bulimia. The reason may have more to do with a few myths about bupropion than the actual evidence.īupropion lacks many of the side effects that can hinder adherence to SSRIs: sexual side effects, weight gain, apathy, sedation, and withdrawal problems.īupropion was the first modern, or “second generation” antidepressant, to enter the market, but it entered the scene in the worst sort of way.
