Prozac is FDA-approved for treating major depressive disorder, panic disorder, obsessive-compulsive disorder (OCD), bulimia nervosa, and premenstrual dysphoric disorder (PMDD). It may also be prescribed off-label for other conditions as determined by a healthcare provider.
As an SSRI, Prozac works by blocking the reabsorption (reuptake) of serotonin in the brain, which helps increase serotonin availability. This improved serotonin signaling is believed to help regulate mood, anxiety, and other related conditions.
Prozac may take several weeks to reach full effectiveness. Common side effects include nausea, headache, insomnia, and sexual dysfunction. It is important to not stop taking Prozac abruptly and to discuss all current medications with a doctor due to potential drug interactions.
