Interactions between your drugs
tranylcypromine ↔ trifluoperazine
Applies to:Parnate (tranylcypromine) and Stelazine (trifluoperazine)
Using trifluoperazine together with tranylcypromine can increase the side effects of both medications. You may be more likely to develop low blood pressure and related problems such as dizziness, lightheadedness, fainting, weakness, and a rapid pulse/heart rate. Nervous system side effects such as drowsiness, confusion, disorientation, memory loss, and seizures may also increase. Let your doctor know if you experience these symptoms and they do not go away after a few days or they become troublesome. These side effects can occur with either medication alone and are most often seen at the beginning of treatment, following a dose increase, or when treatment is restarted after an interruption. Alcohol may also increase these effects, so you should avoid the consumption of alcohol during treatment with these medications. You should seek immediate medical attention if you develop fever, muscle stiffness, confusion, sweating, fast or uneven heartbeats, restless muscle movements in your face or neck, tremor (uncontrolled shaking), or difficulty swallowing. Avoid driving or operating hazardous machinery until you know how the medications affect you, and use caution when getting up from a sitting or lying position. You may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. 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.
