How should I take Paxil?

Take Paxil exactly as prescribed by your doctor. Do not take in larger or smaller amounts or for longer than recommended. Follow the directions on your prescription label. Your doctor may occasionally change your dose to make sure you get the best results.

Shake the oral suspension (liquid) well just before you measure a dose. Measure the liquid with a special dose measuring spoon or medicine cup, not with a regular table spoon. If you do not have a dose measuring device, ask your pharmacist for one.

It may take up to 4 weeks before your symptoms improve. Keep using Paxil as directed and tell your doctor if your symptoms do not improve after 4 weeks of treatment.
