If you develop a severe rash, or a rash with symptoms such as fever, blistering, mouth sores, conjunctivitis, swelling, muscle or joint aches, or general malaise, STOP taking delavirdine. Other common side effects include headache, nausea, diarrhea, sedation and fatigue. Your blood tests will also be checked for any changes in liver function. The long-term side effects of delavirdine are still unknown. If you are concerned about these or any other unexpected side effects, talk to your pharmacist, nurse or physician.
Delavirdine can interact with other drugs.
It is important that your physician or pharmacist knows about other drugs you are taking, even medications you can buy without a prescription. Delavirdine should not be given in combination with rifampin. Rifampin decreases the effectiveness of delavirdine. Delavirdine may affect blood levels of protease inhibitors. Check with your doctor or pharmacist.
