Uses For Prozac


Fluoxetine is used to treat mental depression, obsessive-compulsive disorder (OCD), bulimia nervosa, premenstrual dysphoric disorder (PMDD), and panic disorder.


Fluoxetine is used with olanzapine to treat depression that is a part of bipolar disorder. These medicines are also used together to treat treatment resistant depression in patients who have been treated with other antidepressants that did not work well. This medicine may also be used for other conditions as determined by your doctor.


Fluoxetine belongs to a group of medicines known as selective serotonin reuptake inhibitors (SSRIs). These medicines are thought to work by increasing the activity of a chemical called serotonin in the brain.


This medicine is available only with your doctor's prescription.


Once a medicine has been approved for marketing for a certain use, experience may show that it is also useful for other medical problems. Although these uses are not included in product labeling, fluoxetine is used in certain patients with the following medical conditions:


  • Premature ejaculation.

Before Using Prozac


In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:


Allergies


Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.


Pediatric


Appropriate studies performed to date have not demonstrated pediatric-specific problems that would limit the usefulness of fluoxetine in children with depression. However, safety and efficacy have not been established in children younger than 8 years of age.


Appropriate studies performed to date have not demonstrated pediatric-specific problems that would limit the usefulness of fluoxetine in children with obsessive-compulsive disorder. However, safety and efficacy have not been established in children younger than 7 years of age.


Appropriate studies have not been performed on the relationship of age to the effects of fluoxetine in children with bulimia nervosa and panic disorder. Safety and efficacy have not been established.


Appropriate studies have not been performed on the relationship of age to the effects of olanzapine and fluoxetine combination in the pediatric population. Safety and efficacy have not been established.


Geriatric


Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of fluoxetine in the elderly. However, elderly patients may be more sensitive to the effects of this medicine than younger adults, and are more likely to have hyponatremia (low sodium in the blood), which may require caution and an adjustment in the dose for patients receiving fluoxetine.

Precautions While Using Prozac


It is important that your doctor check your progress at regular visits, to allow changes in your dose and help reduce any side effects. Blood tests may be needed to check for unwanted effects.


Do not take fluoxetine within 2 weeks of taking an monoamine oxidase (MAO) inhibitor (e.g., isocarboxazid [Marplan®], phenelzine [Nardil®], selegiline [Eldepryl®], or tranylcypromine [Parnate®]). Do not take an MAO inhibitor for at least 5 weeks after taking fluoxetine. If you do, you may develop extremely high blood pressure or seizures.


Do not take thioridazine (Mellaril®) while you are taking fluoxetine or less than 5 weeks after you have stopped taking fluoxetine. You should not use pimozide (Orap®) while you are taking this medicine. Using these medicines together can cause very serious heart problems.


You should not take other medicines that also contain fluoxetine. This includes Symbyax®, Sarafem®, or Prozac® Weekly. Using these medicines together may increase your chance for more serious side effects.


If you develop a skin rash or hives, stop taking fluoxetine and check with your doctor as soon as possible.


Fluoxetine may cause some teenagers and young adults to be agitated, irritable, or display other abnormal behaviors. It may also cause some people to have suicidal thoughts and tendencies or to become more depressed. Some people may have trouble sleeping, get upset easily, have a big increase in energy, or start to act reckless. If you or your caregiver notice any of these unwanted effects, tell your doctor right away. Let the doctor know if you, your child, or anyone in your family has bipolar disorder (manic-depressive) or has tried to commit suicide.


Do not stop suddenly taking this medicine without checking first with your doctor. If you have been instructed to stop taking fluoxetine, ask your doctor how to slowly decrease the dose. This is to decrease the chance of having symptoms such as agitation, breathing problems, chest pain, confusion, diarrhea, dizziness or lightheadedness, a fast heartbeat, headache, increased sweating, muscle pain, nausea, restlessness, runny nose, trouble with sleeping, trembling or shaking, unusual tiredness or weakness, vision changes, or vomiting.


Make sure your doctor knows about all the other medicines you are using. Fluoxetine may cause serious conditions such as serotonin syndrome and neuroleptic malignant syndrome (NMS)-like reactions when taken with certain medicines such as linezolid [Zyvox®], lithium, tryptophan, St. John's Wort, or some pain medicines (e.g., tramadol [Ultram®], rizatriptan [Maxalt®], sumatriptan [Imitrex®], or zolmitriptan [Zomig®]). Check with your doctor first before taking any other medicines.


Fluoxetine may increase your risk for bleeding problems. Make sure your doctor knows if you are also using other medicines that thin the blood, such as aspirin, pain or arthritis medicines, sometimes called “NSAIDs” (e.g., ibuprofen, naproxen, Advil®, Aleve®, Celebrex®, or Motrin®), or warfarin (Coumadin®).


Hyponatremia (low sodium in the blood) may occur with this medicine. Stop using the medicine and check with your doctor right away if you have confusion, difficulty concentrating, headaches, memory problems, weakness, and unsteadiness.


Avoid drinking alcohol while you are taking fluoxetine.


For diabetic patients:


  • This medicine may affect blood sugar levels. If you notice a change in the results of your blood or urine sugar tests or if you have any questions, check with your doctor.

This medicine may cause some people to become drowsy or less able to think clearly, or to have poor muscle control. Make sure you know how you react to fluoxetine before you drive, use machines, or do anything else that could be dangerous if you are not alert and well able to control your movements.


Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
