Mental Health Home > Citalopram Side Effects
Shakiness, nausea, and dry mouth are among the side effects that may develop with citalopram. In most cases, such reactions are minor and do not require medical attention, but you should tell your healthcare provider if you experience hallucinations, chest palpitations, or signs of an allergic reaction. Other rare reactions (occurring in less than 1 percent of people) include hypothyroidism, diabetes, and congestive heart failure.
As with any medicine, side effects are possible with citalopram hydrobromide (Celexa®). However, not everyone who takes the antidepressant will experience problems. In fact, most people tolerate it well. If side effects do occur, in most cases, they are minor and either require no treatment or are treated easily by you or your healthcare provider.
(This article covers many, but not all, of the possible side effects with citalopram. Your healthcare provider can discuss a more complete list with you.)

- Suicidal thoughts or behavior (see Celexa and Suicide)

- Engaging in unusual or dangerous activities
- Restlessness or an inability to sit still
