Do not take any other medicines without checking with your doctor first. This includes prescription and nonprescription medicines. This also includes food supplements, herbs and vitamins. To do so may increase the chance of side effects from amprenavir or other medicines.
This medicine may decrease the effects of some oral contraceptives (birth control pills). To avoid unwanted pregnancy, it is a good idea to use some additional contraceptive measures while being treated with amprenavir.
For patients with diabetes: Amprenavir may affect blood sugar levels. If you notice a change in the results of your blood or urine sugar tests or if you have any questions, check with your doctor.
Do not take vitamin E supplements while you are taking amprenavir. At recommended dosages, amprenavir supplies more than the Reference Daily Intake of vitamin E for adults and children.
It is very important that your doctor check your progress at regular visits to make sure this medicine is working properly and to check for unwanted effects, especially increases in blood sugar.
Amprenavir does not decrease the risk of transmitting the HIV infection to others through sexual contact or by contamination through blood. HIV may be acquired from or spread to others through infected body fluids, including blood, vaginal fluid, or semen. If you are infected, it is best to avoid any sexual activity involving an exchange of body fluids with other people. If you do have sex, always wear (or have your partner wear) a condom (“rubber”). Only use condoms made of latex, and use them every time you have vaginal, anal, or oral sex. The use of a spermicide (such as nonoxynol-9) may also help prevent the spread of HIV if it is not irritating to the vagina, rectum, or mouth. Spermicides have been shown to kill HIV in lab tests. Do not use oil-based jelly, cold cream, baby oil, or shortening as a lubricant—these products can cause the condom to break. Lubricants without oil, such as K-Y Jelly, are recommended. Women may wish to carry their own condoms. Birth control pills and diaphragms will help protect against pregnancy, but they will not prevent someone from giving or getting the AIDS virus. If you inject drugs, get help to stop. Do not share needles or equipment with anyone. In some cities, more than half of the drug users are infected, and sharing even 1 needle or syringe can spread the virus. If you have any questions about this, check with your health care professional.
