    Paxil comes in tablet, liquid, or extended-release capsule form and is usually taken once per day, with food or without food.

It is important that you keep taking this medication as prescribed by your doctor, even after you begin to feel better.

Connecting with a therapist or counselor may help a person better understand what he or she is experiencing, learn positive ways to cope, and develop a healthy self-care routine that could facilitate a better, longer-lasting mental health outcome.
