A few people taking Crixivan have had a side effect called hemolytic anemia. Hemolytic anemia means you don't have enough red blood cells. If you are too tired or have yellow skin or your urine is reddish brown, tell your doctor right away.
Hemolytic anemia is very rare, but can get dangerous very quickly.

If you have a type of liver damage known as cirrhosis, talk to your doctor about taking 600 mg of Crixivan every 8 hours instead of 800 mg. The most common side effect of Crixivan is kidney stones. These stones are caused by the Crixivan forming a sludge in the kidneys.
