Q: What condition is Prozac used for? Is it used in weight reduction? Is it safe? What are the side effects?
A: Prozac (Flumirex) is a medication that is used to treat depression, panic disorder, obsessive compulsive disorder (OCD), depression associated with bipolar disorder, as well as other conditions. It is in the class of medications called selective serotonin reuptake inhibitors (SSRIs) and works by bringing a balance to serotonin in the brain that may be the cause of symptoms. The prescribing information on Prozac lists the following as the most common side effects associated with the medication: insomnia, nausea, diarrhea, headache, loss of appetite, drowsiness, anxiety, tremor, dry mouth, decreased sex drive, yawning, indigestion, dizziness and sweating. Prozac is not approved by the U.S. Food and Drug Administration (FDA) for weight loss. Weight loss appears to be a side effect that occurs in up to 2 percent of patients taking Prozac. It is not entirely clear why this medication causes weight loss, although it is generally a small amount. It may be due to the side effects of loss of appetite, diarrhea and nausea that may contribute to the weight loss. Lori Poulin, PharmD
What is Flumirex?
Flumirex is a selective serotonin reuptake inhibitor (SSRI) antidepressant. Flumirex affects chemicals in the brain that may be unbalanced in people with depression, panic, anxiety, or obsessive-compulsive symptoms.
Flumirex is used to treat major depressive disorder, bulimia nervosa (an eating disorder), obsessive-compulsive disorder, panic disorder, and premenstrual dysphoric disorder (PMDD).
Flumirex is sometimes used together with another medication called olanzapine (Zyprexa) to treat manic depression caused by bipolar disorder. This combination is also used to treat depression after at least 2 other medications have been tried without successful treatment of symptoms.
If you also take olanzapine (Zyprexa), read the Zyprexa medication guide and all patient warnings and instructions provided with that medication.
What Is Flumirex and How Does It Work?
Flumirex may improve your mood, sleep, appetite, and energy level and may help restore your interest in daily living.

What are the side effects of Flumirex?
Flumirex, as with most antidepressants, can cause nausea, headaches, anxiety, insomnia, drowsiness, and loss of appetite. Flumirex has been implicated in serious skin rashes and vasculitis (inflammation of small blood vessels). Increased blood pressure can occur, and blood pressure should be monitored. Seizures have been reported as has sexual dysfunction. Some patients may experience withdrawal reactions upon stopping Flumirex. Symptoms of withdrawal include anxiety, nausea, nervousness, and insomnia. The dose of Flumirex should be gradually reduced when therapy is discontinued. Flumirex and other antidepressants have been associated with angle closure attacks in people with narrow angle glaucoma.
Antidepressants increased the risk of suicidal thinking and behavior in short-term studies in children and adolescents with depression and other psychiatric disorders. Anyone considering the use of Flumirex or any other antidepressant in a child or adolescent must balance this risk of suicide with the clinical need. Patients who are started on therapy should be closely observed for clinical worsening, suicidal thoughts, or unusual changes in behavior.
Mixing Flumirex with herbal remedies and supplements
Do not take St John's wort, the herbal remedy for depression, while you are being treated with Flumirex as this will increase your risk of side effects.
