Why is paxil prescribed?

Paxil (Paroxetine) tablets, suspension (liquid) and extended-release (long-acting) tablets are used to treat depression, panic disorder (sudden, unexpected attacks of extreme fear and worry about these attacks), and social anxiety disorder (extreme fear of interacting with others or performing in front of others that interferes with normal life). Paxil tablets and oral solution are also used to treat obsessive compulsive disorder (bothersome thoughts that won't go away and the need to perform certain actions over and over), generalized anxiety disorder (excessive worrying that is difficult to control), and posttraumatic stress disorder (disturbing psychological symptoms that develop after a frightening experience). Paxil extended-release tablets are also used to treat premenstrual dysphoric disorder (PMDD, physical and psychological symptoms that occur before the onset of the menstrual period each month). Paroxetine is in a class of medications called selective serotonin reuptake inhibitors (SSRIs). It works by increasing the amount of serotonin, a natural substance in the brain that helps maintain mental balance.

How should paxil be used properly?

Paroxetine (Paxil) comes as a tablet, a suspension (liquid), and a controlled-release (long-acting) tablet to take by mouth. It is usually taken once daily in the morning or evening, with or without food. You may want to take paroxetine with food to stop it from upsetting your stomach. To help you remember to take paroxetine, take it around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take paroxetine exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Shake the liquid well before each use to mix the medication evenly.

Swallow the extended-release tablets whole; do not split, chew, or crush them.

Your doctor may start you on a low dose of paroxetine and gradually increase your dose, not more than once a week.

Paroxetine controls your condition but does not cure it. It may take several weeks or longer before you feel the full benefit of paroxetine. Continue to take paroxetine even if you feel well. Do not stop taking paroxetine without talking to your doctor. Your doctor will probably decrease your dose gradually. If you suddenly stop taking paroxetine, you may experience withdrawal symptoms such as depression; mood changes; frenzied or abnormally excited mood; irritability; anxiety; confusion; dizziness; headache; tiredness; numbness or tingling in the arms, legs, hands, or feet; unusual dreams; difficulty falling asleep or staying asleep; upset stomach; or sweating. Tell your doctor if you experience any of these symptoms when your dose of paroxetine is decreased.

Talk to your doctor about the possible risks of using this drug for your condition.

This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
