Enfuvirtide Side Effects
What should I watch for?
Visit your doctor or health care professional for regular check ups. Discuss any new symptoms with your doctor. You will need to have important blood work done while on this medicine.
This medicine causes injection site reactions. The reactions are usually mild to moderate, but can be severe. They usually happen within the first week of using the medicine and happen again as you keep using it. Each injection site reaction usually does not last longer than 7 days. The reactions may be worse when injections are given in the same place on the body or when the injection is given deeper than it should be (for example, into the muscle). Sometimes an injection site can get infected. Be sure to follow the instructions you get with this medicine. Following the instructions may help to lower your chance of getting an infection.
