General Information

Citalopram is an antidepressant drug prescribed for the treatment of depression and associated anxiety/panic disorders. It is of particular use in patients with ongoing feelings of sadness, despair, worthlessness, hopelessness, fatigue, pessimism and difficulty dealing with normal daily life

Citalopram, and products related to it, is as effective as other, older groups of antidepressants with the advantage of fewer side effects and drug interactions. It also does not lead to the same weight gain that is seen when these older types of antidepressants are used.

It may take several weeks for the full benefit of citalopram to be achieved. During this period it is important to continue taking the medication.

How does citalopram work?

Citalopram is a selective serotonin re-uptake inhibitor (SSRI), meaning that it increases the levels of the neurotransmitter serotonin in the brain. Increased levels of serotonin are associated with an improvement in emotion, mood and mental state.
