Drug Interactions and HIV/AIDS
There is a long list of prescription, over-the-counter, complementary, and recreational drugs that may have significant interactions with HIV medications. Food and beverages can also change the way HIV drugs are broken down in the body. Below are a few examples:
Birth Control Pills
Birth control pills containing ethinyl estradiol (a form of estrogen) can interact with HIV drugs. This can make the pills less effective and increase the chances of pregnancy. If your HIV drugs affect the levels of your birth control pills, talk with your provider about switching to or adding another form of birth control.
Many HIV+ people use complementary therapies such as vitamins or herbs. While most of these have not been studied with HIV drugs, St. John's Wort (an herbal anti-depressant) and garlic supplements have been shown to affect the levels of some HIV drugs. St. John's Wort should not be taken with any PIs or NNRTIs. It is important to tell your health care provider if you take any vitamins, herbs, or supplements.
Recreational Drugs and Alcohol
There have been reports of overdoses, some fatal, caused by taking recreational drugs and HIV drugs. Interactions between ecstasy or amphetamines (crystal meth, speed) and PIs are particularly dangerous.
Alcohol affects body processes and is often responsible for drug interactions. Combining alcohol and certain HIV drugs like Videx can put you at risk for developing pancreatitis (inflammation of the pancreas).
Methadone can interact with many HIV drugs. It is important to tell the health care provider at the methadone program and your HIV health care provider what you are taking. This way necessary adjustments can be made to insure you get enough methadone to prevent withdrawal symptoms and enough HIV drugs to fight the virus effectively.
There are certain classes of drugs to treat different medical conditions that are more likely to interact with HIV drugs. Not all drugs in these classes will cause problems. If you take any of the following types of drugs, talk to your health care provider about the specific drugs you take and if there are any possible interactions. Note: this is not a complete list; other classes of drugs may also cause interactions.
Any pills that you take go through your stomach. What you eat can affect how much of your drugs get into your system. Most drugs are absorbed faster if your stomach is empty. For some drugs, this is a good thing, but it can also cause more side effects. Some drugs need to be taken with food so that they are broken down more slowly, or to reduce their side effects. Others should be taken with fatty foods because they dissolve in fat and are absorbed better. Check your drug labels and follow the food instructions carefully. If you have any questions, it is important to ask your provider or pharmacist.
HIV+ people often have to take many different drugs. Sometimes taking more than one medication can cause drug interactions. This can lead to the drugs not working as well or an increased risk of side effects.
Because there are so many possible drug interactions with the HIV drugs, it is very important for you and your health care provider to go over all your medications (including over-the-counter, prescription, street drugs, and complimentary therapies), even if you only use them occasionally. Your health care provider may need to adjust the doses of your drugs to avoid under- or overdosing or change the drugs you currently take.
