Store Paroxetine between 68 and 77 degrees F (20 and 25 degrees C). Brief storage at temperatures between 59 and 86 degrees F (15 and 30 degrees C) is permitted. Store away from heat, moisture, and light. Do not store in the bathroom. Keep Paroxetine out of the reach of children and away from pets.

Check with your doctor before you use medicines that may cause drowsiness (eg, sleep aids, muscle relaxers) while you are using Paroxetine ; it may add to their effects. Ask your pharmacist if you have questions about which medicines may cause drowsiness.
Several weeks may pass before your symptoms improve. Do not take more than the recommended dose, change your dose, or use Paroxetine for longer than prescribed without checking with your doctor.
Children, teenagers, and young adults who take Paroxetine may be at increased risk for suicidal thoughts or actions. Watch all patients who take Paroxetine closely. Contact the doctor at once if new, worsened, or sudden symptoms such as depressed mood; anxious, restless, or irritable behavior; panic attacks; or any unusual change in mood or behavior occur. Contact the doctor right away if any signs of suicidal thoughts or actions occur.
If your doctor tells you to stop taking Paroxetine , you will need to wait for several weeks before beginning to take certain other medicines (e.g., MAOIs, nefazodone). Ask your doctor when you should start to take your new medicines after you have stopped taking Paroxetine.
Paroxetine may rarely cause a prolonged, painful erection. This could happen even when you are not having sex. If this is not treated right away, it could lead to permanent sexual problems such as impotence. Contact your doctor right away if this happens.
Serotonin syndrome is a possibly fatal syndrome that can be caused by Paroxetine . Your risk may be greater if you take Paroxetine with certain other medicines (e.g., "triptans," MAOIs).
