Antidepressants may increase the risk of suicidal thoughts or actions in children, teenagers, and young adults. However, depression and certain other mental problems may also increase the risk of suicide. Talk with the patient's doctor to be sure that the benefits of using paroxetine outweigh the risks.
Families and caregivers must closely watch patients who take paroxetine. It is important to keep in close contact with the patient's doctor. Tell the doctor right away if the patient has symptoms like worsened depression, suicidal thoughts, or changes in behavior. Discuss any questions with the patient's doctor.
Paroxetine is not approved for use in children. Talk with the doctor.
Paroxetine is used for:
Treating depression or obsessive-compulsive disorder (OCD). It may be used to treat panic disorder or posttraumatic stress disorder (PTSD). It may also be used to treat generalized anxiety disorder or social anxiety disorder. It may also be used for other conditions as determined by your doctor.
Paroxetine is a selective serotonin reuptake inhibitor (SSRI). It works by restoring the balance of serotonin, a natural substance in the brain, which helps to improve certain mood problems.
