IMPORTANT WARNING

A small number of children, teenagers, and young adults (up to 24 years of age) who took antidepressants ('mood elevators') such as paroxetine during clinical studies became suicidal (thinking about harming or killing oneself or planning or trying to do so). Children, teenagers, and young adults who take antidepressants to treat depression or other mental illnesses may be more likely to become suicidal than children, teenagers, and young adults who do not take antidepressants to treat these conditions. However, experts are not sure about how great this risk is and how much it should be considered in deciding whether a child or teenager should take an antidepressant. Children younger than 18 years of age should not normally take paroxetine, but in some cases, a doctor may decide that paroxetine is the best medication to treat a child's condition.

You should know that your mental health may change in unexpected ways when you take paroxetine or other antidepressants even if you are an adult over 24 years of age. You may become suicidal, especially at the beginning of your treatment and any time that your dose is increased or decreased. You, your family, or your caregiver should call your doctor right away if you experience any of the following symptoms: new or worsening depression; thinking about harming or killing yourself, or planning or trying to do so; extreme worry; agitation; panic attacks; difficulty falling asleep or staying asleep; aggressive behavior; irritability; acting without thinking; severe restlessness; and frenzied abnormal excitement. Be sure that your family or caregiver knows which symptoms may be serious so they can call the doctor if you are unable to seek treatment on your own.

Your healthcare provider will want to see you often while you are taking paroxetine, especially at the beginning of your treatment. Be sure to keep all appointments for office visits with your doctor.

The doctor or pharmacist will give you the manufacturer's patient information sheet (Medication Guide) when you begin treatment with paroxetine. Read the information carefully and ask your doctor or pharmacist if you have any questions. You can also obtain the Medication Guide from the FDA website: Web Site.

No matter what your age, before you take an antidepressant, you, your parent, or your caregiver should talk to your doctor about the risks and benefits of treating your condition with an antidepressant or with other treatments. You should also talk about the risks and benefits of not treating your condition. You should know that having depression or another mental illness greatly increases the risk that you will become suicidal. This risk is higher if you or anyone in your family has or has ever had bipolar disorder (mood that changes from depressed to abnormally excited) or mania (frenzied, abnormally excited mood) or has thought about or attempted suicide. Talk to your doctor about your condition, symptoms, and personal and family medical history. You and your doctor will decide what type of treatment is right for you.

WHY is this medicine 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 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 this medicine be used?

Paroxetine 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 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.

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; nausea; or sweating. Tell your doctor if you experience any of these symptoms when your dose of paroxetine is decreased.

Are there OTHER USES for this medicine?

Paroxetine is also sometimes used to treat chronic headaches, tingling in the hands and feet caused by diabetes, and certain male sexual problems. Paroxetine is also used with other medications to treat bipolar disorder (mood that changes from depressed to abnormally excited). 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.
