HIV Positive Patients that Drink Alcohol Are Less Likely to Take Their Medications
HIV positive patients that drink alcohol are less likely to take their medications as directed, and as alcohol consumption goes up, medication regimen adherence goes down.
Antiretroviral therapy is a medication treatment for HIV that can extend lifespan and quality of life for a significant number of years, but to be effective, patients need to strictly comply with the medication taking regimen – taking a lot of pills each day on a precise schedule.
Researchers at the University of Washington wanted to know what kind of influence alcohol consumption had on antiretroviral regimen compliance rates, and to do so they looked back at study data from 40 past research studies involving more than 25 000 subjects.
They found that HIV positive patients that abstained from alcohol were twice as likely as those who drank alcohol to comply with their medication regimen, and that the more people drank, the worse the compliance rates became.
The frequency of drinking alcohol seemed less significant than the amount consumed in a session, and those who were classified as at-risk drinkers, were the least likely to adhere to medication regimens.
Lead researcher Jane Simonni, says that its important to understand what factors can increase HIV medication regimen compliance rates, saying, "typical adherence for people taking medication is 50 percent. But 50 or 60 percent adherence isn't going to work for HIV medications and will lead to resistance to the drugs. Taking drugs for HIV is a lifetime commitment; you are married to the pills.”
