Drug Interaction Report

The following interaction applies only if you are taking potassium in a solid formulation (i.E., tablet or capsule swallowed whole):

Talk to your doctor before using potassium oral tablets or capsules together with trifluoperazine. Depending on the dose of trifluoperazine and your overall physical health, combining these medications may increase the irritant effects of potassium on your stomach and upper intestine. This can rarely result in ulcers, bleeding, and other gastrointestinal injury. Contact your doctor immediately if you develop severe abdominal pain, bloating, sudden dizziness or lightheadedness, nausea, vomiting (especially with blood), loss of appetite, and/or black, tarry stools during treatment with these medications. Alternatively, a liquid formulation of potassium may be considered when used in combination with trifluoperazine. 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.

Ask your doctor before using trifluoperazine together with ethanol (alcohol). This can cause uncontrollable movements, agitation, seizures, severe dizziness or fainting, coma, very deep sleep, irregular heartbeats, and high or low body temperature. Use caution when driving, operating machinery, or performing other hazardous activities, these medicaions may cause dizziness or drowsiness. If you experience dizziness or drowsiness, avoid these activities. 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.
