ABACAVIR - ORAL
Common Brand Name
In some patients, abacavir has caused a serious (sometimes fatal) allergic reaction. Your doctor should order a blood test to measure your risk before you start this medication or take it again. If the blood test shows you are at greater risk, you should not take this medication and your doctor should discuss other treatment choices with you. Symptoms of an allergic reaction may include any of the following: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing, fever, extreme tiredness, nausea, vomiting, diarrhea, stomach pain, muscle aches, sore throat, or cough. Get medical help right away if you experience any of these symptoms. If you have stopped taking abacavir because of an allergic reaction, you must never take any form of abacavir again, or death could result. Tell all of your doctors and pharmacists if you have stopped taking abacavir due to an allergic reaction. Also, properly throw away any unused abacavir. Read the warning card provided with this medication for more details. Rarely, abacavir has caused severe (sometimes fatal) liver problems and a certain metabolic problem (lactic acidosis). Get medical help right away if you develop any of the following symptoms: nausea, vomiting, stomach/abdominal pain, unusual tiredness, dark urine, yellowing eyes/skin, deep/rapid breathing, or drowsiness. These serious side effects may occur more often in women and obese patients.
This drug is used with other HIV medications to help control HIV infection. It helps to decrease the amount of HIV in your body so your immune system can work better. This lowers your chance of getting HIV complications (such as new infections, cancer) and improves your quality of life. Abacavir belongs to a class of drugs known as nucleoside reverse transcriptase inhibitors-NRTI. Abacavir is not a cure for HIV infection. To decrease your risk of spreading HIV disease to others, do all of the following: (1) continue to take all HIV medications exactly as prescribed by your doctor, (2) always use an effective barrier method (latex or polyurethane condoms/dental dams) during all sexual activity, and (3) do not share personal items (such as needles/syringes, toothbrushes, and razors) that may have contacted blood or other body fluids. Consult your doctor or pharmacist for more details.
How to Use
Read the Medication Guide and Warning Card provided by your pharmacist before you start taking abacavir and each time you get a refill. Carry the Warning Card with you at all times. If you have any questions, ask your doctor or pharmacist. Take this medication by mouth, usually 1-2 times daily with or without food or as directed by your doctor. If you are using the liquid form of this medication, carefully measure the dose using a special measuring device/spoon. Do not use a household spoon because you may not get the correct dose. The dosage is based on your medical condition and response to treatment. In children, the dosage is also based on weight. If you stop using abacavir even for a short time and then restart the drug, you have an increased chance of developing a very serious (possibly fatal) allergic reaction. Refill your medication before you run out. Do not stop treatment unless directed by your doctor. Before restarting abacavir, consult your doctor or pharmacist, and be sure you have easy access to medical care. It is very important to continue taking this medication (and other HIV medications) exactly as prescribed by your doctor. Do not skip any doses. Do not increase your dose, take this drug more often than prescribed, or stop taking it (or other HIV medicines) even for a short time unless directed to do so by your doctor. Skipping or changing your dose without approval from your doctor may cause the amount of virus to increase, make the infection more difficult to treat (resistant), or worsen side effects. This medication works best when the amount of drug in your body is kept at a constant level. Therefore, take this drug at evenly spaced intervals. To help you remember, take it at the same time(s) each day.
See also Warning and How to Use sections. Trouble sleeping or loss of appetite may occur. If any of these effects persist or worsen, notify your doctor or pharmacist promptly. Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects. As your immune system gets stronger, it can begin to fight off infections you already had, possibly causing disease symptoms to come back. You could also have symptoms if your immune system becomes overactive. This reaction may happen at any time (soon after starting HIV treatment or many months later). Get medical help right away if you have any serious symptoms, including: unexplained weight loss, severe tiredness, muscle aches/weakness that doesn't go away, headaches that are severe or don't go away, joint pain, numbness/tingling of the hands/feet/arms/legs, vision changes, signs of infection (such as fever, chills, swollen lymph nodes, trouble breathing, cough, non-healing skin sores), signs of an overactive thyroid (such as irritability, nervousness, heat intolerance, fast/pounding/irregular heartbeat, bulging eyes, unusual growth in the neck/thyroid known as a goiter), signs of a certain nerve problem known as Guillain-Barre syndrome (such as trouble breathing/swallowing/moving your eyes, drooping face, paralysis, trouble speaking). Tell your doctor right away if you have any serious side effects, including: mental/mood changes (depression, anxiety). Changes in body fat (such as increased fat in the upper back and stomach areas, decreased fat in the arms and legs) may occur while you are taking HIV medication. The cause and long-term effects of these changes are unknown. Discuss the risks and benefits of therapy with your doctor, as well as the possible role of exercise to reduce this side effect. This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.
