Frequently asked questions
Do antipsychotics cause weight gain?
Several can increase appetite, weight and blood sugar, so these are monitored. The benefit for serious conditions usually outweighs this, and your doctor manages it.
Can I stop an antipsychotic when I feel well?
Not on your own — stopping can trigger relapse. Any change should be planned with your psychiatrist.
