Like most medicines, antiretroviral drugs can cause side effects. These unwanted effects are often mild, but sometimes they are more serious and can have a major impact on health or quality of life. On rare occasions, side effects can be life threatening. Once started, antiretroviral treatment must be taken every day for life. Every missed dose increases the risk that the drugs will stop working. It is therefore vital that people receiving antiretroviral treatment get all the help they need to minimise the impact of side effects. Often there are several ways to lessen the harm, either by treating the side effects or by switching to alternative antiretroviral drugs. back to topVariation in side effects

Antiretroviral drugs differ in how commonly they cause particular side effects. For example, efavirenz is the drug most associated with psychiatric symptoms, while protease inhibitors are more likely to raise levels of cholesterol and triglycerides. This should be considered when deciding which drugs to take. Side effects vary from person to person and it is impossible to predict exactly how each individual will be affected. Some people take antiretroviral treatment for years with few problems, while others find the same drugs intolerable. Nevertheless some characteristics and pre-existing conditions (such as high blood pressure or hepatitis infection) are known to increase the risk from certain side effects. Doctors should assess these factors before advising patients on which drugs to choose. back to topDuration of side effects

Some side effects appear shortly after starting an antiretroviral drug and disappear within a few weeks as the body gets used to the new chemicals. This is often the case with nausea, diarrhoea and headache, for example. Unfortunately other side effects – such as peripheral neuropathy (nerve damage) and lipodystrophy (fat redistribution) – tend to worsen over time and may never go away. Also some problems may not emerge until months or even years after treatment is started. back to topPreparing to start treatment

Those preparing to take antiretroviral treatment for the first time, or about to switch drugs, are well advised to learn a little about the most commonly associated side effects. This should help them deal with problems as soon as they arise. Patients should also know how to spot the warning signs of more serious side effects that may require immediate intervention. back to topReporting side effects

Because side effects are unpredictable, may occur at any time, and can be very serious, it is essential that all symptoms be reported during appointments with a doctor. Severe or unexpected events should be reported immediately. Keeping a side effects diary is a good way to keep track of when symptoms occur, how often and how severely. If side effects are affecting quality of life or treatment adherence then this too should be reported. back to topIdentifying the cause

Most side effects are not uniquely associated with a particular drug, and sometimes it can be difficult to identify the cause. HIV itself is capable of producing many of the symptoms that also occur as drug side effects. Other possible causes include opportunistic infections, stress, diet, and non-HIV drugs. “Patients should make sure their doctors are aware of all drugs they are taking” Patients should make sure their doctors are aware of all drugs they are taking. This means not only pharmaceuticals but also recreational drugs and complementary and alternative therapies. It may be that a side effect is due to one of these other substances, either directly or because of an interaction with the antiretroviral medication. The more information is shared with a doctor, the better equipped they will be to help. Older people living with HIV may experience signs of ageing that could resemble certain side effects. For example, when people get older they might be more susceptible to increased fat in the abdomen, which...
