Like all medications Citalopram comes with side effects.
Some of the side effects of Citalopram are dose dependent, so you're less likely to have them at a lower dose than a higher one. It's also important to let you doctor know if you're taking any other medications including herbs and supplements that can interact with Citalopram and increase the risk of side effects. Interactions can occur with a variety of different medications, including other anti-depressants. Your doctor should also be aware of any other medical conditions you have, especially heart disease, liver disease, kidney disease or seizures.
Other ways to reduce the risk of Citalopram side effects include taking only the dose prescribed by your doctor. Taking more than the prescribed amount increases the risk for side effects. Avoid drinking alcohol when you're on this medication since the combination can make you drowsy. If you have side effects that seem intolerable, don't stop the medication. Talk to your doctor first. Your doctor may be able to lower the dose. Reference: Yahoo Health.
