What are the side effects of citalopram?

Mild side effects of citalopram include: nausea, diarrhea, headaches, insomnia, decreased urination, cold symptoms, gas, sleepiness, sexual disinterest, weight changes, particularly dry or moist mouth or weakness. Seek medical assistance if these symptoms persist or worsen. In some cases symptoms of an allergic reaction, such as skin rash, swelling in the face or difficulty breathing, have been reported. They require immediate medical attention. Other serious side effects include: diarrhea and vomiting accompanied by loss of appetite; feelings of unsteadiness or lack of coordination; eye pain, changes in vision or swelling or redness in the eye; muscle rigidity accompanied by a high fever, tremors, overactive reflexes and irregular heartbeat; or memory problems accompanied by headaches, concentration troubles, confusion, hallucinations, seizures, fainting or shallow breathing. If you experience any of these side effects while taking citalopram, contact your physician immediately. Other serious side effects, such as hostile, irritable or panicked emotions that lead to thoughts of suicide, have been reported. If you notice pronounced negative changes in your mood, talk to your doctor.
