Fluoxetine is an oral drug that belongs to the selective serotonin reuptake inhibitor (SSRI) class. This medication is generally sold with the trade names Prozac and Sarafem, however, it is also available as a generic medicine. This medicine is generally prescribed to treat depression, anxiety, panic attacks, and obsessive compulsive disorder in both adults as well as children. It is also used to treat bulimia nervosa and premenstrual dysphoric disorder. The nerves within our brain use certain chemicals, known as neurotransmitters, to communicate with each other. These neurotransmitters are produced and released by the nerves as means of communication. These chemicals then travel to a different nerve and get attached to its surface, or to the surface of the nerves that produce them, and are released again. This process is known as reuptake. It is believed that an imbalance of the neurotransmitters is the main cause of depression. This medication prevents the reuptake of one such neurotransmitter, serotonin. Due to this reduced uptake, the brain increases the free serotonin that stimulates nerve cells of the brain, thus lowering depression. Dosage Fluoxetine dosage varies depending on a number of factors such as the condition, its intensity, and the patient's response. The recommended dosage to treat resistant depression in adults is 20 to 50 mg per day. It is better to start with a single dose of 20 mg, taken daily in the morning. This dose can then be increased gradually depending on the patient's response after 4 to 6 weeks of treatment. The recommended dosage to treat depression in children is 10 to 20 mg per day.
