Precautions
It is very important that your doctor check your progress at regular visits to make sure this medicine is working properly. Blood tests may be needed to check for unwanted effects.
When you start taking HIV medicines, your immune system may get stronger. If you already have certain infections such as pneumonia, herpes, or tuberculosis, you may notice new symptoms when your body tries to fight them. If this occurs, be sure to tell your doctor right away.
This medicine may cause some people to become dizzy. If this happens, do not drive, use machines, or do anything else that could be dangerous if you are dizzy. You may also feel lightheaded when getting up suddenly from a lying or sitting position, so stand up slowly.
Liver problems with allergic reactions may occur while you are using this medicine. Stop using this medicine and check with your doctor right away if you have a skin rash with fever, dark-colored urine, pain in the upper right stomach area, vomiting, or yellow eyes or skin.
Using this medicine may increase your risk of getting infections or cancer. Talk to your doctor if you have concerns about this risk.
This medicine will not keep you from giving HIV to your partner during sex. Make sure you understand and practice safe sex, even if your partner also has HIV, by using a latex condom or other barrier method. This medicine will also not keep you from giving HIV to other people if they are exposed to your blood. Do not re-use or share needles with anyone.
Tell all of your doctors that you are using this medicine before you have any medical tests. The results of some tests may be affected by this medicine.
Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal (e.g., St. John's wort) or vitamin supplements.
