Cautions with other medicines
Some medicines can be affected by citalopram, and other medicines can affect the way citalopram works. Using citalopram with other medicines can increase the chances of you having side effects.
Before you start taking citalopram, tell your doctor if you're taking:
- any medicines that affect your heartbeat – citalopram can make your heart beat faster or cause an irregular heartbeat
(arrhythmia) - any other medicines for depression – some rarely used antidepressants can affect citalopram and cause very high blood pressure even if you have not taken them for a few weeks
Mixing citalopram with herbal remedies and supplements
Do not take St John's wort, the herbal remedy for depression, while you're being treated with citalopram because it increases your risk of side effects.
It's not possible to say that other herbal remedies or supplements are safe to take with citalopram. They're not tested in the same way as pharmacy and prescription medicines. They're generally not tested for the effect they have on other medicines.
Important: Medicine safety
Tell your doctor or pharmacist if you're taking any other medicines, including herbal remedies, vitamins or supplements.
