Type of Drug:
Antidepressant; mood-elevating agent.
How the Drug Works:
Citalopram blocks the uptake of a chemical found in the brain (serotonin) which increases the activity of this chemical, resulting in improved mood.
Uses:
To treat depression.
Pregnancy: Adequate studies have not been done in pregnant women. Use only if clearly needed and potential benefits outweigh the possible hazards to the fetus.
Breastfeeding: Citalopram appears in breast milk. A decision should be made whether to discontinue nursing or discontinue the drug, taking into account the risks to the infant of citalopram exposure (eg, excessive drowsiness, decreased feeding, weight loss) and the importance of the drug to the mother. Consult your doctor before you begin breastfeeding.
Children: Safety and effectiveness in children have not been established.
Elderly: Older individuals may be more sensitive to the effects of citalopram than younger individuals. The recommended dose for most elderly patients is 20 mg/day with titration to 40 mg/day only for nonresponding patients.
Drug Interactions:
Tell your doctor if you are taking or are planning to take any over-thecounter or prescription medications while taking citalopram. Doses of one or both drugs may need to be modified or a different drug may need to be prescribed. The following drugs and drug classes interact with citalopram: alcohol
- Carbamazepine (eg, Tegretol)
- Cimetidine (eg, Tagamet)
- CNS drugs (eg, antidepressants)
