Like most medical specialties. antiretroviral drugs can do side effects. These unwanted effects are frequently mild. but sometimes they are more serious and can hold a major impact on wellness or quality of life. On rare occasions. side effects can be life endangering. Once started. antiretroviral intervention must be taken every twenty-four hours for life. Every missed dosage increases the hazard that the drugs will halt working. It is hence critical that people having antiretroviral intervention acquire all the aid they need to understate the impact of side effects. Often there are several ways to decrease the injury. either by handling the side effects or by exchanging to alternate antiretroviral drugs. back to topVariation in side effects

Antiretroviral drugs differ in how normally they cause peculiar side effects. For illustration. efavirenz is the drug most associated with psychiatric symptoms. while peptidase inhibitors are more likely to raise degrees of cholesterin and triglycerides. This should be considered when make up one’s minding which drugs to take. Side effects vary from individual to individual and it is impossible to foretell precisely how each person will be affected. Some people take antiretroviral intervention for old ages with few jobs. while others find the same drugs unbearable. Nevertheless some features and preexistent conditions ( such as high blood force per unit area or hepatitis infection ) are known to increase the hazard from certain side effects. Doctors should measure these factors before reding patients on which drugs to take. back to topDuration of side effects

Some side effects appear shortly after get downing an antiretroviral drug and disappear within a few hebdomads as the organic structure gets used to the new chemicals. This is frequently the instance with sickness. diarrhea and concern. for illustration. Unfortunately other side effects – such as peripheral neuropathy ( nerve harm ) and lipodystrophy ( fat redistribution ) – tend to decline over clip and may ne’er travel off. Besides some jobs may non emerge until months or even old ages after intervention is started. back to topPreparing to get down intervention

Those fixing to take antiretroviral intervention for the first clip. or about to exchange drugs. are good advised to larn a small about the most normally associated side effects. This should assist them cover with jobs every bit shortly as they arise. Patients should besides cognize how to descry the warning marks of more serious side effects that may necessitate immediate intercession. back to topReporting side effects

Because side effects are unpredictable. may happen at any clip. and can be really serious. it is indispensable that all symptoms be reported during assignments with a physician. Severe or unexpected events should be reported instantly. Keeping a side effects diary is a good manner to maintain path of when symptoms occur. how frequently and how badly. If side effects are impacting quality of life or intervention attachment so this excessively should be reported. back to topIdentifying the cause

Most side effects are non unambiguously associated with a peculiar drug. and sometimes it can be hard to place the cause. HIV itself is capable of bring forthing many of the symptoms that besides occur as drug side effects. Other possible causes include timeserving infections. emphasis. diet. and non-HIV drugs. “Patients should do certain their physicians are cognizant of all drugs they are taking” Patients should do certain their physicians are cognizant of all drugs they are taking. This means non lone pharmaceuticals but besides recreational drugs and complementary and alternate therapies. It may be that a side consequence is due to one of these other substances. either straight or because of an interaction with the antiretroviral medicine. The more information is shared with a physician. the better equipped they will be to assist. Older people populating with HIV may see marks of ageing that could resemble certain side effects. For illustration. when people get older they might be more susceptible to increased fat in the venters. which could look similar to the alterations that are caused by lipodystrophy. back to topDealing with side effects

There may be several options for covering with a peculiar side consequence: •Wait for things to better – particularly if in the first few hebdomads of intervention •Address other possible lending factors. such as diet. smoke or exercising •Change how the drug is taken ( e. g. clip of twenty-four hours. dose. with or without nutrient ) •Try handling the side consequence

•Change one or more antiretroviral drugs
Switch overing drugs is frequently an effectual manner to cut down or extinguish a side consequence when all other attacks have failed. If the viral burden is undetectable so it is normally possible to exchange merely one drug without impacting intervention effectivity or future intervention options. Otherwise. the full combination may hold to be changed. Switch overing drugs is non without hazards. As already mentioned. it can be hard to place the cause of a peculiar set of symptoms. and it may turn out that the jilted drug or drugs weren’t to fault after all. There is besides a opportunity that the new medicine may do even worse side effects. possibly coercing another switch. Changing drugs repeatedly will contract future intervention options. It is of import to weigh the possible hazards and benefits before make up one’s minding on this class of action. It is ne’er a good thought to halt intervention without first confer withing a physician. as this may do HIV to develop drug opposition. For information on covering with hurting straight see our AIDS and hurting page. back to topOverview of antiretroviral drug side effects

Some of the side effects of antiretroviral drugs are described below. get downing with five of the most noteworthy. This is non a complete list. Diarrhoea

Diarrhoea is a common side consequence of many antiretroviral drugs – particularly protease inhibitors. A survey reappraisal has found that 60 per centum of people populating with HIV study diarrhea. 1 Other possible causes include HIV. the consequence that HIV has on the GI piece of land. other infections and antibiotics. 2 Sometimes an antiretroviral drug causes diarrhea for merely the first few hebdomads ; in other instances this side consequence lasts for every bit long as the drug is taken. Bananas assistance recovery from diarrhea

The badness of diarrhea besides varies. While even occasional onslaughts may be inconvenient and abashing. relentless diarrhea can besides take to desiccation. hapless soaking up of foods and drugs. weight loss and weariness. Drinking plentifulness of fluids and replacing electrolytes will cut down the hazard of desiccation. Electrolytes – such as K. Na and Mg ions – are indispensable to wellness and are depleted by diarrhea. Wayss of replacing electrolytes include unwritten rehydration salts ( available from pharmaceuticss ) . athleticss rehydration drinks ( such as Gatorade or Powerade. though the high sugar content may decline diarrhea ) . diluted fruit juices. soups. and homemade rehydration mixtures ( 8 degree teaspoons of sugar and 1 degree teaspoon of table salt per liter of H2O ) . Eating bananas. murphies. fish or poulet will assist to replace K. Although it may non be plenty to work out the job. altering diet may cut down the badness of diarrhea. Good advice includes: •Eat less indissoluble fiber ( natural veggies. fruit teguments. wholegrain bread or cereal. seeds and nuts ) •Eat more soluble fiber ( white rice. pasta. oat bran tablets. psyllium/isphagula ) •Cut down on caffeine. intoxicant and the sweetening sorbitol •Avoid greasy. fatso. spicy and sugary nutrients

•Consider cut downing dairy merchandises in instance of lactose intolerance •Consult a dietician
There is presently no recommended therapy for non-infectious signifiers of diarrhea in HIV-positive people. 3 Nonprescription medical specialties such as Imodium ( loperamide ) . Lomotil ( diphenoxylate and atropine ) and Ca addendums are sometimes all that is needed to command diarrhea. If these fail so physicians can order stronger interventions. which may hold to be injected. Sometimes nil plants. and altering drugs may be the best option. Nausea and emesis

About all antiretroviral drugs. every bit good as many other medicines. can do sickness ( experiencing sick ) and purging. particularly during the first few hebdomads of intervention. Although this side consequence can cut down appetite. it is of import to maintain eating when possible. and to replace lost fluids and electrolytes ( as with diarrhea ) . The undermentioned steps may assist: •Eat several little repasts alternatively of a few big repasts

•Avoid spicy. greasy and rich nutrients ; take bland nutrients
•Eat cold instead than hot repasts
•Don’t drink with a repast or shortly after
•Avoid intoxicant. acetylsalicylic acid and smoke
•Avoid cookery odors

Some antiretroviral drugs can be taken with nutrient. and making so may decrease their harmful effects. It may besides be possible to change drug dose or frequence. Assorted interventions. known as anti-emetics. are available for sickness and emesis. some of which do non necessitate a prescription. There is some grounds that ginger and Mentha piperita may assist against sickness. If sickness and emesis are terrible. or occur with other symptoms such as giddiness. thirst. febrility. musculus hurting. diarrhea. concern or icterus. so this may bespeak a more serious job such as lactic acidiosis or pancreatitis. In this instance medical attending should be sought every bit shortly as possible. Rash

Rashs frequently appear as a side consequence of antiretroviral intervention. These may be antsy but are normally harmless and ephemeral. However. terrible roseolas can happen with Viramune. and more seldom with some other drugs. Any rash occurring during the first few hebdomads of intervention should be reported to a physician instantly. as should any rash accompanied by febrility. vesiculation. facial puffiness or achings. A roseola happening with abacavir may bespeak a really unsafe hypersensitivity reaction. as described subsequently in this page. Tips for get bying with roseolas include:

•Avoiding hot showers or baths
•Using milder toilet articless and wash detergents
•Wearing cool fibers such as cotton. and avoiding wool
•Humidifying the air
•Trying moisturisers/emollients or hemimorphite lotion
Antihistamine tablets can sooth roseolas and are by and large available without a prescription. However. because these may interact with antiretroviral medicines. patients should look into with their physicians before utilizing them. More terrible tegument jobs may be treated with steroids. Lipodystrophy

Lipodystrophy involves losing or deriving organic structure fat. frequently in ways that can be defacing and stigmatizing. Three chief forms are seen: •Losing fat on the face. weaponries. legs and natess. ensuing in deep-set cheeks. outstanding venas on the limbs. and shriveled natess. •Gaining fat deep within the venters. between the shoulder blades. or on the chests. •A mixture of fat addition and fat loss.

Although lipodystrophy sometimes affects people with HIV who have non taken any antiretroviral drugs. it occurs more frequently among those having intervention. The status is among the most common long-run side effects of combinations of drugs from the NRTI and protease inhibitor categories. It is peculiarly associated with stavudine. and to a lesser extent Retrovir. The precise causes of lipodystrophy remain unknown. “The interventions for lipodystrophy are unhappily limited”

The interventions for lipodystrophy are unhappily limited. Changing diet seems to do no important difference. though opposition exercising ( such as weight raising ) may better the visual aspect of limbs by constructing musculus to counterbalance for lost fat. Any signifier of exercising will fire fat. which may do some parts of the organic structure look better and others worse. depending on how fat has been redistributed. Aerobic exercising ( such as running or swimming ) tends to hold more consequence on the fat merely below the tegument than on the deep fat gained through lipodystrophy. Doctors have tried utilizing assorted medicines. including human growing endocrine. to handle lipodystrophy. but few have proved effectual. and most have important side effects. For people who have lost fat from the face. one option is injections of polylactic acid. This chemical ( besides known as New Fill or Sculptra ) improves facial visual aspect by inspissating the tegument. Switch overing antiretroviral intervention should halt the symptoms acquiring worse. but is improbable to take to much betterment once the status has advanced. Lipid abnormalcies and the bosom

Lipid abnormalcies are another common side consequence of some antiretroviral drugs – peculiarly protease inhibitors – and are frequently seen in people who besides have lipodystrophy. Lipids are molecules of fat. cholesterin and related chemicals that have of import functions in the organic structure. Many factors including diet. smoke and exercising can impact the balance of these chemicals in the blood. Abnormal lipid degrees can be harmful to wellness. HIV positive people taking antiretroviral intervention normally have high degrees of a lipoid called LDL cholesterin. low degrees of HDL cholesterin. and high degrees of triglyceride in the blood. Among HIV negative people such lipid abnormalcies have been linked to greater hazards of bosom disease. shot and diabetes. Oily fish are good for lipid degrees

The first stairss in handling lipid abnormalcies should be related to diet and lifestyle. General recommendations include giving up smoking. taking more exercising. cutting Calories. eating less fat. and devouring more fibre and omega-3 fatty acids ( found in oily fish and linseed ) . However. people populating with HIV should seek expert advice on using these guidelines. For illustration. cutting Calories may endanger efforts to construct musculus. while eating less fat is non needfully a good thought for people taking certain peptidase inhibitors that require fatty nutrients to help soaking up.

Yet although diet and lifestyle alterations should ever be portion of the scheme. they are frequently unequal to rectify the job. Doctors may order medicines such as lipid-lowering medicines and fibrates to better lipid degrees. or they may rede exchanging intervention. In 2008. a big probe called the D: A: Calciferol study4 reported that usage of the NRTI abacavir was associated with a higher hazard of myocardial infarction ( besides known as bosom onslaught ) compared to other drugs in the same category. Since so. some surveies have supported the findings of the D: A: Calciferol survey while others have contested these findings and found no increased hazard of bosom onslaught with abacavir. The tabular array below shows the findings of the relevant surveies and tests that have taken topographic point so far: Abacavir and increased hazard of bosom onslaught

Evidence for increased hazard No grounds for increased hazard 2008 D: A: Calciferol analyze A multi-cohort survey affecting 33347 patients finds a 90 % per centum increased hazard of bosom onslaught with usage of abacavir and a 49 % increased hazard with didanosine5

SMART/INSIGHT Study analysed the D: A: Calciferol findings and concluded that abacavir. but non didanosine. was associated with increased hazard of bosom attack6

GSK statement GSK’s Internal databases of 54 clinical tests with more than 14. 000 patients. over 9. 600 of whom were on abacavir show no increased hazard of bosom attack7

Allrt Study of 5056 patients found no increased hazard of bosom onslaught from either short or long term usage of abacavir. Traditional hazard factors. such as smoke and older age were alternatively attributed to increased hazard. 8

US Veteran Affairs Department Study of 10. 931 patients found an increased hazard of cardiovascular events associated with recent usage of abacavir9

FDA 26 randomised clinical tests concluded that there was no increased hazard of bosom onslaught with abacavir10
