What is the most important information I should know about PREZISTA®?
- PREZISTA® can interact with other medicines and cause serious side effects. See “Who should not take PREZISTA®?”
- PREZISTA® may cause liver problems. Some people taking PREZISTA®, together with NORVIR® (ritonavir), have developed liver problems which may be life-threatening. Your healthcare provider should do blood tests before and during your combination treatment with PREZISTA®. If you have chronic hepatitis B or C infection, your healthcare provider should check your blood tests more often because you have an increased chance of developing liver problems
- Tell your healthcare provider if you have any of these signs and symptoms of liver problems: dark (tea-colored) urine, yellowing of your skin or whites of your eyes, pale-colored stools (bowel movements), nausea, vomiting, pain or tenderness on your right side below your ribs, loss of appetite, or tiredness.
- PREZISTA® may cause severe or life-threatening skin reactions or rash. Sometimes these skin reactions and skin rashes can become severe and require treatment in a hospital. You should call your healthcare provider immediately if you develop a rash. Stop taking PREZISTA® and ritonavir combination treatment and call your healthcare provider immediately if you develop any skin changes with these symptoms: fever, tiredness, muscle or joint pain, blisters or skin lesions, mouth sores or ulcers, red or inflamed eyes like “pink eye.” Rash occurred more often in people taking PREZISTA® and raltegravir together than with either drug separately, but was generally mild.
