Let's take a minute to talk about your medication. This is Sustiva. Sustiva can help keep HIV infection under control. People with HIV have a better quality of life and are living longer than ever before. To do so, it's important to take HIV medications exactly as directed. You should take Sustiva on an empty stomach. Taking it at bedtime may lessen some side effects. You must swallow the tablets or capsules whole. If your doctor recommends opening the capsules, it's important to read the instructions. Some side effects can occur,like feeling tired, dizzy or nauseous. Wait until you know how it affects you before doing activities that require you to be alert, like driving. These effects are normal if they are mild and should go away. Over time, you could also have changes in body fat. This could change the look of your face or body. If these or other side effects become reasons you want to stop taking this medicine, please talk to your doctor or pharmacist. But, don't stop taking it unless your doctor says it's okay. As with any medicine, rare but serious side effects could occur. Your doctor will follow you closely. You should read the 'Patient Information Guide' to know what to watch for. Skin rashes are common, but can be serious. If you get a rash, stop taking Sustiva and call your doctor right away. While taking Sustiva, you must still take precautions to prevent spreading HIV to others. Also, you must check with your doctor or pharmacist before taking any new medicines or before drinking alcohol. Sustiva can harm babies. Women should avoid breastfeeding, and talk to their doctors about special precautions to prevent pregnancy. For best results, plan ahead for refills, because missing even a few doses can worsen your infection.
