How it works
Citalopram is in a class of medication called selective serotonin reuptake inhibitors (SSRIs). It is used to treat depression, generalized anxiety disorder, eating disorders, alcoholism, panic disorder, premenstrual dysphoric disorder, social phobia, and other conditions. Citalopram works by increasing the amount of serotonin, a natural substance in the brain that helps maintain mental balance.
Safety
Citalopram is a non-controlled medication, which means that it is not classified as having euphoric or addictive properties. There are no cravings, no hazardous behaviors, and no examples of prolonged addictive behavior associated with it.
Citalopram may make you drowsy. Do not drive a car or operate machinery until you know how this medication affects you. Remember that alcohol can add to the drowsiness caused by this medication and make the side effects of citalopram worse.
How it should be used
It may take 2 to 4 weeks or longer before you feel the full benefit of citalopram. Continue to take citalopram even if you feel well.
Do not stop taking citalopram without talking to your doctor. If you suddenly stop taking citalopram, you may experience withdrawal symptoms such as mood changes, irritability, agitation, dizziness, numbness, tingling or electric shock-like sensations in the hands or feet, anxiety, confusion, headache, tiredness, nausea, sweating, shaking, and difficulty falling asleep or staying asleep. Your doctor will probably decrease your dose gradually.
What to do if you forget a dose
Take the missed dose as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.
