Drug Interactions between Abilify and fluoxetine / olanzapine

Using OLANZapine together with FLUoxetine can increase the risk of an irregular heart rhythm that may be serious and potentially life-threatening, although it is a relatively rare side effect. You may be more susceptible if you have a heart condition called congenital long QT syndrome, other cardiac diseases, conduction abnormalities, or electrolyte disturbances (for example, magnesium or potassium loss due to severe or prolonged diarrhea or vomiting). Talk to your doctor if you have any questions or concerns. Your doctor may already be aware of the risks, but has determined that this is the best course of treatment for you and has taken appropriate precautions and is monitoring you closely for any potential complications. You should seek immediate medical attention if you develop sudden dizziness, lightheadedness, fainting, shortness of breath, or heart palpitations during treatment with these medications, whether together or alone. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

FLUoxetine may increase the blood levels and effects of ARIPiprazole. This can make you more likely to develop side effects such as drowsiness, seizure, Parkinson-like symptoms, abnormal muscle movements, and low blood pressure. You may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. Contact your doctor if you experience agitation, aggression, confusion, convulsions, muscle spasm, or movements that you can't stop or control such as lip smacking, chewing, puckering, frowning or scowling, tongue thrusting, teeth clenching, jaw twitching, blinking, eye rolling, shaking or jerking of arms and legs, tremor, jitteriness, restlessness, pacing, and foot tapping. Also be alert to symptoms of low blood pressure such as dizziness, lightheadedness, fainting, and/or increased pulse or heart rate. Avoid driving or operating hazardous machinery until you know how these medications affect you, and use caution when getting up from a sitting or lying position, especially at the beginning of treatment or after an increase in dose of ARIPiprazole. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Using OLANZapine together with ARIPiprazole may increase side effects such as drowsiness, blurred vision, dry mouth, heat intolerance, flushing, decreased sweating, difficulty urinating, abdominal cramping, constipation, irregular heartbeat, confusion, and memory problems. Side effects may be more likely to occur in the elderly or those with a debilitating condition. You should avoid or limit the use of alcohol while being treated with these medications.
