🔀 Citalopram with other medicines, food and alcohol
The label says to discuss these with your doctor or pharmacist
- Monoamine oxidase inhibitors (MAOIs), including linezolid and intravenous methylene blue. These are not allowed with citalopram.
- Pimozide. Citalopram is not allowed with this medicine.
- Medicines that prolong the QT interval. The label says to avoid these where possible, and it lists CYP2C19 inhibitors as needing a lower maximum dose.
- Other serotonin-affecting medicines, such as other SSRIs, SNRIs, triptans, tricyclic antidepressants, opioids (including tramadol, fentanyl, meperidine, and methadone), lithium, buspirone, amphetamines, tryptophan, and St. John's Wort. These can raise the risk of serotonin syndrome.
- Medicines that affect blood clotting, such as aspirin, NSAIDs, other antiplatelet drugs, and warfarin or other anticoagulants. These may increase the risk of bleeding.
- Diuretics, gatifloxacin or moxifloxacin, and antiarrhythmic medicines are also listed in the label as medicines to discuss with your provider.

🤰 Citalopram in pregnancy and breastfeeding
Pregnancy
The label says citalopram may harm an unborn baby. Taking it late in pregnancy may lead to an increased risk of certain problems in the newborn, including persistent pulmonary hypertension of the newborn (PPHN) and poor neonatal adaptation. The label also says untreated depression during pregnancy carries its own risks, so the benefits and risks should be discussed with your provider. The label mentions a National Pregnancy Registry for Antidepressants, which can be reached at 1-844-405-6185 or https://womensmentalhealth.org/research/pregnancyregistry/antidepressants.
Breastfeeding

🗓️ Storage, missed doses and taking too much

If a dose is missed
The label does not say.
If too much is taken
The label says overdose has been reported to cause seizures, which may be delayed, and altered mental status including coma. It can also cause heart problems such as QRS and QTc interval prolongation, wide complex tachyarrhythmias, and torsade de pointes. High blood pressure is most common, though low blood pressure can occur, sometimes with alcohol or other substances. Serotonin syndrome may occur, with a higher risk when other serotonin-affecting drugs are involved. The label recommends prolonged cardiac monitoring after overdose and says activated charcoal may be considered if treatment is started early. Seek emergency medical help right away if an overdose is suspected.
