- Standard adult dose: 1 x tablet (containing 300 mg 3TC + 600 mg abacavir), once-daily.
- Take with or without food.
- Side effects: hypersensitvity reaction (from abacavir). A genetic test, called HLA B*5701, is now used in the UK that reduces this risk. A negative result does not guarantee that you will not get this reaction, but makes it much less likely. For more details see individual drugs.
