Prozac (Fluoxetine HCl)
Prozac is an antidepressant medicine known as a selective serotonin reuptake inhibitor (SSRI). It is used to treat major depressive disorder, obsessive compulsive disorder, bulimia (eating disorder), and panic disorder. Prozac is also used with an antipsychotic medicine called olanzapine to treat depressive episodes associated with bipolar disorder and treatment-resistant depression (depression that has not improved with two separate treatments of different antidepressant medicines).
Prozac can increase the risk of suicidal thoughts and behavior in children, adolescents, and young adults. Your doctor will monitor you closely for clinical worsening, suicidal or unusual behavior after you start taking Prozac or start a new dose of Prozac. Tell your doctor right away if you experience anxiety, hostility, sleeplessness, restlessness, impulsive or dangerous behavior, or thoughts about suicide or dying; or if you have new symptoms or seem to be feeling worse.
Prozac can cause serotonin syndrome (a potentially life-threatening drug reaction that causes the body to have too much serotonin, a chemical produced by the nerve cells) or neuroleptic malignant syndrome (a brain disorder) when you take it alone or in combination with other medicines. You can experience mental status changes, an increase in your heart rate and temperature, lack of coordination, overactive reflexes, muscle rigidity, nausea, vomiting, or diarrhea. Tell your doctor right away if you experience any of these signs or symptoms.
Prozac can cause severe allergic reactions. Tell your doctor right away if you develop a rash, trouble breathing, or swelling of your face, tongue, eyes, or mouth.
Your risk of abnormal bleeding or bruising can increase if you take Prozac, especially if you also take blood thinners (such as warfarin), nonsteroidal anti-inflammatory drugs (NSAIDs) (such as ibuprofen or naproxen), or aspirin.
You can experience manic episodes while you are taking Prozac. Tell your doctor if you experience greatly increased energy, severe trouble sleeping, racing thoughts, reckless behavior, unusually grand ideas, excessive happiness or irritability, or talking more or faster than usual.
Prozac can cause seizures or changes in your appetite or weight. Your doctor will monitor you for these effects during treatment.
Prozac can decrease your blood sodium levels, especially if you are elderly. Tell your doctor if you have a headache, weakness, an unsteady feeling, confusion, problems concentrating or thinking, or memory problems while you are taking Prozac.
Prozac can affect your blood sugar levels. If you are a diabetic, make sure you check your blood sugar levels regularly.
Do not stop taking Prozac without first talking to your doctor. Stopping Prozac suddenly can cause serious symptoms, including anxiety, irritability, changes in your mood, feeling restless, changes in your sleep habits, headache, sweating, nausea, dizziness, electric shock-like sensations, shaking, or confusion.
