Interactions between your drugs

Moderate

promethazine gepirone

Applies to: promethazine and gepirone

Using gepirone together with promethazine may increase the risk of experiencing a change in the electrical activity of your heart called QT prolongation, which can result in irregular heartbeats that can be life-threatening. You might be more susceptible to this risk if you have heart problems, uncontrolled hypothyroidism, or electrolyte disturbances (for example, magnesium or potassium loss due to severe or prolonged diarrhea or vomiting). Your doctor may be able to prescribe alternatives that do not interact, or you may need a dose adjustment or more frequent monitoring of your electrocardiogram and blood tests to safely use both medications. You should seek immediate medical attention if you experience an irregular heartbeat or feeling dizzy, lightheaded, or faint during treatment. 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.
