Head-to-head comparisons of medication uses, side effects, warnings, and more.
Key takeaways
Bupropion (Wellbutrin) and citalopram (Celexa) are both medications used to treat depression, but they belong to different drug classes and work in different ways. Bupropion is an atypical antidepressant that boosts norepinephrine and dopamine levels in the brain, while citalopram is a selective serotonin reuptake inhibitor (SSRI) that increases serotonin levels. Bupropion is available in short-acting, sustained-release, and extended-release tablets, whereas citalopram comes as a tablet, liquid, and capsule. Bupropion is less likely to cause weight gain and sexual side effects compared to other antidepressants, but it can increase the risk of seizures, especially in people with a history of seizures. Citalopram, on the other hand, has a low risk of weight gain but can cause serious heart rhythm problems (QT prolongation) and serotonin syndrome if taken with other medications that affect serotonin levels. Both medications can take several weeks to show their full effects and should not be stopped suddenly to avoid withdrawal symptoms.
Bupropion is taken by mouth to treat depression and seasonal affective disorder (SAD). It's available as short-acting tablets that are taken two or three times a day, as well as long-acting versions that are taken once daily. Bupropion has fewer sexual side effects compared to other antidepressants, but it's not a good choice for people with a history of seizures, eating disorders, or drink alcohol regularly.
Summary for SSRI
Prescription only
Citalopram (Celexa) is a first-choice medication for treating depression in adults. This antidepressant belongs to the drug class called selective serotonin reuptake inhibitors (SSRIs). Citalopram (Celexa) is typically taken by mouth once daily. It typically takes a few weeks or longer of consistent treatment to notice an improvement to your mood. Common side effects include nausea and dry mouth. There's a low risk for weight gain, but suddenly stopping the medication can lead to withdrawal symptoms (e.g., upset stomach, trouble sleeping, anxiety).
