Rapiflux (Oral)

Fluoxetine is used to treat depression, obsessive-compulsive disorder (OCD), bulimia nervosa, premenstrual dysphoric disorder (PMDD), and panic disorder. It is also used with olanzapine to treat depression that comes with bipolar disorder and treatment-resistant depression in patients who have already tried at least 2 previous treatments that did not work well.

Fluoxetine is an antidepressant and is part of a group of medicines called selective serotonin reuptake inhibitors (SSRIs). This medicine works by increasing the activity of a chemical in the brain called serotonin.

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

It is important for your doctor to monitor your progress during regular visits to ensure that this medicine is working correctly. Blood tests may be needed to check for any unwanted effects.

Do not take fluoxetine with a monoamine oxidase (MAO) inhibitor (for example, isocarboxazid [Marplan®], linezolid [Zyvox®], methylene blue injection, phenelzine [Nardil®], selegiline [Eldepryl®], tranylcypromine [Parnate®]). Do not start taking fluoxetine within 2 weeks after you stop a MAO inhibitor, and wait 5 weeks after stopping fluoxetine before starting a MAO inhibitor. Taking them together or not waiting the right amount of time may lead to confusion, agitation, restlessness, stomach or intestinal symptoms, a sudden high body temperature, extremely high blood pressure, or severe convulsions.

Do not take thioridazine (Mellaril®) with fluoxetine and wait 5 weeks after stopping fluoxetine before starting thioridazine. Do not use pimozide (Orap®) with fluoxetine. Using these medicines together can lead to very serious heart problems.

Fluoxetine may cause a serious condition called serotonin syndrome if taken with certain medicines. Do not use fluoxetine with buspirone (Buspar®), fentanyl (Abstral®, Duragesic®), lithium (Eskalith®, Lithobid®), tryptophan, St. John's wort, amphetamines, or some pain or migraine medicines (for example, meperidine, methadone, rizatriptan, sumatriptan, tramadol, Demerol®, Frova®, Imitrex®, Maxalt®, Methadose®, Relpax®, Ultram®, Zomig®). Check with your doctor before taking any other medicines with fluoxetine.

Fluoxetine may cause some teenagers and young adults to feel agitated, irritable, or show other unusual behaviors. It may also lead to some people having thoughts of suicide or becoming more depressed. Some people may have trouble sleeping, get upset easily, feel a big increase in energy, or start to act recklessly. If you or your caregiver notice any of these unwanted effects, inform your doctor immediately. Let the doctor know if you or anyone in your family has bipolar disorder (manic-depressive) or has attempted suicide.

Do not stop taking this medicine suddenly without consulting your doctor first. Your doctor may want you to gradually decrease your dosage before stopping completely. This will lower the chance of withdrawal symptoms such as agitation, breathing problems, chest pain, confusion, diarrhea, dizziness or lightheadedness, fast heartbeat, headache, increased sweating, muscle pain, nausea, restlessness, runny nose, trouble sleeping, trembling or shaking, unusual tiredness or weakness, vision changes, or vomiting.

Tell your doctor immediately if you develop a rash or hives, swelling of the face, eyes, or mouth, or have trouble breathing after taking this medicine.

This medicine may increase your risk for bleeding problems. Make sure your doctor is aware if you are also taking other medicines that thin the blood, such as NSAIDs (for example, aspirin, diclofenac, ibuprofen, naproxen, Advil®, Aleve®, Celebrex®, Voltaren®) or warfarin (Coumadin®, Jantoven®).

Hyponatremia (low sodium in the blood) may occur with this medicine. Contact your doctor immediately if you experience confusion, difficulty concentrating, headaches, memory problems, weakness, and unsteadiness.

Reach out to your doctor right away if you experience dizziness, fainting, or a fast, pounding, or uneven heartbeat. Ensure your doctor knows if you have ever had a heart rhythm problem, including QT prolongation, or if you or a family member has had a heart attack, heart failure, low blood pressure, or a stroke.

Avoid alcohol if you are taking fluoxetine.

This medicine may affect blood sugar levels. If you are diabetic and notice a change in your blood or urine sugar test results, consult your doctor.

Fluoxetine may cause some people to feel drowsy, less able to think clearly, or have poor muscle control. Make sure you understand how fluoxetine affects you before driving, using machines, or doing anything else that could be dangerous if you are not alert and able to control your movements.

Check with your doctor right away if you experience decreased interest in sexual intercourse, delays or inability to have an orgasm in women, inability to have or maintain an erection in men, or loss of sexual ability, desire, drive, or performance. These could be signs of sexual dysfunction.

Do not take other medicines unless you have discussed them with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal (for example, St. John's wort) or vitamin supplements.

In deciding to use a medicine, the risks of using the drug must be weighed against the good it will do. This is a decision you and your physician 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 drug or any other medicines. Also inform 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. However, safety and efficacy have not been established to treat depression in children younger than 8 years of age, to treat obsessive-compulsive disorder in children younger than 7 years of age, and to treat depression that is part of bipolar disorder in children younger than 10 years of age.

Appropriate studies have not been performed on the relationship of age to the effects of fluoxetine in children with bulimia nervosa, panic disorder, or therapy resistant depression. 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. Nevertheless, elderly patients are more likely to have hyponatremia (low sodium in the blood) than younger adults, which may require caution and an adjustment in the dose for patients receiving fluoxetine.

Breast Feeding

There are no adequate studies in women for determining infant risk when using this medicine during breastfeeding. Weigh the potential benefits against the potential risks prior to taking this drug while breastfeeding.
