Abacavir Uses And Side Effects.
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, continue to take all HIV medications exactly as prescribed by your doctor.
Use an effective barrier method (latex or polyurethane condoms/dental dams) during sexual activity as directed by your doctor.
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 Abacavir.
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.
For the best effect, take this medication at evenly spaced times. To help you remember, take this medication at the same time(s) every day.

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 goitre), 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).
Rarely, this medication has caused severe (sometimes fatal) liver problems and a buildup of lactic acid in the blood (lactic acidosis). These serious side effects may occur more often in women and obese patients. Get medical help right away if you have any of the following serious symptoms, including symptoms of liver problems (such as nausea/vomiting that doesn’t stop, stomach/abdominal pain, yellowing eyes/skin, dark urine), symptoms of lactic acidosis (such as deep/rapid breathing, drowsiness, nausea/vomiting).
