It is primarily used to treat major depressive disorder and anxiety disorders. While it can be effective in managing symptoms of these conditions, it's crucial to be aware of its potential severe side effects. ## Common Side Effects Before delving into the severe side effects, it's important to acknowledge the more common, less severe side effects that many patients experience: - Nausea and digestive issues - Dry mouth - Fatigue and drowsiness - Insomnia - Sexual dysfunction - Increased sweating - Mild headaches These side effects are generally mild and tend to diminish as the body adjusts to the medication. ## Life-Threatening Side Effects ### Serotonin Syndrome One of the most serious risks associated with citalopram is serotonin syndrome, a potentially life-threatening condition that occurs when there is excess serotonin in the brain. Symptoms include: 1. Agitation or restlessness 2. Confusion 3. High fever 4. Rapid heart rate 5. High blood pressure 6. Muscle rigidity or twitching 7. Seizures > **Emergency Alert**: If you experience any symptoms of serotonin syndrome, seek immediate medical attention. ### Cardiac Complications The [FDA has issued warnings](https://www.fda.gov/drugs/drug-safety-and-availability/fda-drug-safety-communication-revised-recommendations-celexa-citalopram-hydrobromide-related) about citalopram's potential to cause dangerous heart rhythm abnormalities, particularly QT interval prolongation.
