Prozac is an antidepressant in a group of drugs called selective serotonin reuptake inhibitors (SSRIs). Prozac affects chemicals in the brain that may become unbalanced and cause depression, panic, anxiety, or obsessive-compulsive symptoms.
Prozac is used to treat major depressive disorder, bulimia nervosa (an eating disorder) obsessive-compulsive disorder, panic disorder, and premenstrual dysphoric disorder (PMDD).
Prozac is sometimes used together with another medication called olanzapine (Zyprexa) to treat depression caused by bipolar disorder (manic depression). This combination is also used to treat depression after at least 2 other medications have been tried without successful treatment of symptoms

It should not be understood to indicate that the use of this medicine is safe, appropriate or effective for you. Always consult your health care professional before using this, or any other, drug.

Do not take Prozac together with pimozide (Orap), thioridazine (Mellaril), or a monoamine oxidase inhibitor (MAOI) such as isocarboxazid (Marplan), phenelzine (Nardil), rasagiline (Azilect), selegiline (Eldepryl, Emsam), or tranylcypromine (Parnate).

You may have thoughts about suicide when you first start taking an antidepressant, especially if you are younger than 24 years old. Your doctor will need to check you at regular visits for at least the first 12 weeks of treatment with Prozac.

Call your doctor at once if you have any new or worsening symptoms such as: mood or behavior changes, anxiety, panic attacks, trouble sleeping, or if you feel impulsive, irritable, agitated, hostile, aggressive, restless, hyperactive (mentally or physically), more depressed, or have thoughts about suicide or hurting yourself. SSRI antidepressants may cause serious or life-threatening lung problems in newborn babies whose mothers take the medication during pregnancy. However, you may have a relapse of depression if you stop taking your antidepressant during pregnancy. If you are planning a pregnancy, or if you become pregnant while taking Prozac, do not stop taking the medication without first talking to your doctor.

Get emergency medical help if you have any of these signs of an allergic reaction: skin rash or hives; difficulty breathing; swelling of your face, lips, tongue, or throat.

Take Prozac exactly as it was prescribed for you. Do not take the medication in larger amounts, or take it for longer than recommended by your doctor. Follow the directions on your prescription label.

Your doctor may occasionally change your dose to make sure you get the best results from the medication.

Do not break, chew, or open an extended-release capsule. Swallow the pill whole. It is specially made to release medicine slowly in the body. Breaking the pill would cause too much of the drug to be released at one time.

Measure the liquid form of Prozac with a special dose-measuring spoon or cup, not a regular table spoon. If you do not have a dose-measuring device, ask your pharmacist where you can get one.

It may take 4 weeks or longer before you start feeling better. Do not stop using Prozac without first talking to your doctor. You may have unpleasant side effects if you stop taking this medication suddenly.

To treat premenstrual dysphoric disorder, the usual dose of Prozac is once daily while you are having your period, or 14 days before you expect your period to start. Follow your doctor`s instructions.

Store Prozac at room temperature away from moisture and heat.
