What to do if you miss a dose of Celexa

Missing a dose of Celexa (Citalopram) is common — most people will skip a dose at some point during a course. The right action depends on how long since the missed dose and whether Celexa is taken event-driven or daily at 10mg, 20mg, 40mg. The wrong action — doubling up — is not recommended.

For daily Celexa

If Celexa is taken daily for a chronic condition, take the missed dose as soon as you remember, unless it is almost time for the next scheduled dose. In that case skip the missed dose and continue normally. According to the prescribing information for Citalopram, two doses should never be taken close together to "make up" for a miss.

For event-driven Celexa

If Celexa is used as needed (not on a fixed schedule), there is no "missed dose" in the conventional sense — simply take the planned dose when needed and observe the recommended gap before re-dosing. Citalopram selectively inhibits the serotonin reuptake transporter, increasing synaptic serotonin availability with limited affinity for noradrenaline transporters or other receptors.

Frequently asked questions

Should I double the dose if I missed Celexa? ▾

No. Doubling doses of Celexa to compensate is not recommended at any 10mg, 20mg, 40mg strength and increases the risk of side effects without improving efficacy. Take the next scheduled dose normally.

How many missed doses are too many? ▾

Occasional missed doses of Celexa are usually inconsequential. Repeated missed doses can compromise the therapeutic effect — for chronic conditions like those treated with Anti-Depressants, consistent dosing matters. If adherence is hard, discuss reminders, simpler schedules or alternative formulations with the prescriber.
