What is PEXEVA® (paroxetine mesylate)?
PEXEVA is an antidepressant in the drug group called selective serotonin reuptake inhibitors (SSRIs). SSRIs are a group of drugs that are believed to act by balancing the activity of serotonin in the brain. Serotonin is a chemical with many actions in the body; one of the functions of serotonin in the brain is to modify mood and behavior.
In people with depression, PEXEVA can help resolve symptoms like sadness, low energy, sleep difficulty, irritability, or despair. PEXEVA is indicated for either depression, obsessive compulsive disorder, generalized anxiety disorder, or panic disorder. PEXEVA contains paroxetine mesylate, a form of paroxetine.
PEXEVA is not addicting and is not a controlled substance, but do not stop taking PEXEVA without talking to your doctor. Stopping PEXEVA suddenly can cause other symptoms. That's why you should never stop your medication without speaking with your doctor first, even if you start feeling better. There is no generic alternative for PEXEVA, please confirm with your pharmacist that you receive the branded medication that you were prescribed before leaving the pharmacy.
If your refill tablets do not look like this, consult your physician.

Depression is a serious medical condition that in some people can lead to suicidal thoughts. As with any medication, there are benefits and risks with PEXEVA. It is important to discuss these
