Some mutations can keep multiplying even when you are taking an antiviral drug. When this happens, the drug will stop working. Abacavir appears to work even when HIV has some resistance to other reverse transcriptase inhibitors. Abacavir is taken by mouth as a capsule. The capsules are 300mg, so you will take 1 capsule at a time.
Children take a liquid form.
The amount of liquid depends on the child's body weight. Abacavir can be taken with food, or between meals. When you start any anti-viral treatment, you may have temporary side effects such as headaches, high blood pressure, or a general sense of feeling ill. These side effects usually get better or disappear over time. The most common side effects of abacavir are headache, nausea and vomiting.
