Fact Sheet
Following an HIV Treatment Regimen
Part of HIV and Its Treatment

August 2012

Terms Used in This Fact Sheet

Regimen: A combination of three or more anti-HIV medications from at least two different drug classes.

Treatment adherence: Closely following an HIV treatment regimen -- taking the correct dose of each anti-HIV medication at the correct time and exactly as prescribed.

How can I prepare for adherence before I start HIV treatment?

Preparing for adherence before you start taking anti-HIV medications is the first step to treatment success. Planning ahead will help you follow your treatment regimen once you start treatment.

Begin by talking to your health care provider. Make sure you understand why you're starting HIV treatment and why treatment adherence is important. Discuss these important details about your treatment regimen:

Talk to your health care provider about other medications you take and their possible side effects. Your health care provider will tell you about potential interactions between the anti-HIV medications in your regimen and the other medications you take.

Tell your health care provider if you have any personal issues, such as depression or alcohol or drug abuse, that can make adherence difficult. If needed, your health care provider can recommend resources to help you address these issues before you start treatment.

How can I maintain adherence after I start treatment?


Consider one or more of the following strategies to help you adhere to your regimen:

What should I do if I forget to take my medications?

Unless your health care provider tells you otherwise, take a medication you missed as soon as you realize you skipped it. But if it's almost time for the next dose of the medication, don't take the missed dose and just continue on your regular medication schedule. Don't take a double dose of a medication to make up for a missed dose.

What should I do if I have problems adhering to my treatment regimen?

Tell your health care provider that you're having difficulty following your regimen. Together you can identify the reasons why you're skipping medications.

Tell your health care provider about any side effects from the medications in your regimen. Side effects are a major reason treatment adherence can be difficult. A regimen that involves taking many pills at many times during the day can also make adherence difficult.

Based on why you're having problems with adherence, your health care provider may adjust or change your regimen. (See the "Changing an HIV Treatment Regimen" fact sheet.)
