Why is this medication prescribed?
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). Paroxetine tablets and suspension 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 (GAD; excessive worrying that is difficult to control), and posttraumatic stress disorder (disturbing psychological symptoms that develop after a frightening experience). Paroxetine 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 capsules (Brisdelle) are used to treat hot flashes (sudden feelings of warmth, especially in the face, neck, and chest) in women who are experiencing menopause (stage of life when menstrual periods become less frequent and stop and women may experience other symptoms and body changes). Paroxetine is in a class of medications called selective serotonin-reuptake inhibitors (SSRIs). It treats depression and other mental illnesses by increasing the amount of serotonin, a natural substance in the brain that helps maintain mental balance. There is not enough information available at this time to know how paroxetine works to treat hot flashes.
How should this medicine be used?
Paroxetine comes as a tablet, a suspension (liquid), a controlled-release (long-acting) tablet, and a capsule to take by mouth. The tablets, suspension, and controlled-release tablets are usually taken once daily in the morning or evening, with or without food. The capsules are usually taken once a day at bedtime with or without food. You may want to take paroxetine with food to prevent stomach upset. Take paroxetine at 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 and regular tablets whole; do not chew or crush them.
If you are taking paroxetine tablets, suspension, or controlled-release tablets, your doctor may start you on a low dose of paroxetine and gradually increase your dose, not more than once a week.
Paroxetine capsules contain a lower dose of paroxetine than is needed to treat depression and other forms of mental illness. Do not take paroxetine capsules to treat a mental illness. If you think you have depression or another mental illness, talk to your doctor about treatment.
Paroxetine may help control your symptoms but will not cure your condition. 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 may decrease your dose gradually. If you suddenly stop taking paroxetine tablets, suspension, or controlled-release tablets, 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; nausea; or sweating. Tell your doctor if you experience any of these symptoms when your dose of paroxetine is decreased.
