Drug Interaction Report

Using amprenavir together with alosetron can increase the blood levels or add to the side effects of alosetron. Contact your doctor if you experience constipation or signs and symptoms of ischemic colitis such as rectal bleeding, bloody diarrhea, and new or worsening abdominal pain. If your doctor does prescribe these medications together, you may need a dose adjustment or special tests to safely take 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.

Amprenavir can be taken with or without food. Avoid taking with a high-fat meal, which can make it harder for your body to absorb amprenavir. Take amprenavir with a full glass (8 ounces) of water. Do not switch from amprenavir capsules to oral liquid without your doctor's advice. Make sure you receive the right form of this medication each time you get your prescription filled.
