Head-to-head comparisons of medication uses, side effects, warnings, and more.
Key takeaways
Citalopram (Celexa) and bupropion (Wellbutrin XL, Wellbutrin SR) are both medications used to treat depression, but they belong to different medication classes. Citalopram is a selective serotonin reuptake inhibitor (SSRI), while bupropion is an atypical antidepressant. Citalopram is typically taken once daily and is also available in a liquid form, whereas bupropion comes in immediate-release, sustained-release, and extended-release tablets, with dosing varying from once to three times daily depending on the formulation. Bupropion is also FDA-approved for treating seasonal affective disorder (SAD), which is not an indication for citalopram. Common side effects of citalopram include nausea and dry mouth, while bupropion may cause headaches and trouble sleeping. Both medications can interact with medications affecting serotonin levels, increasing the risk of serotonin syndrome, while bupropion has a higher risk of seizures, especially in those with a history of seizures or eating disorders. Both medications are available in generic forms, making them more affordable options for treating depression.

Summary of Citalopram vs. Wellbutrin XL
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).
Summary for Atypical antidepressant
Prescription only
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.
