- T-20 (enfuvirtide, tradename Fuzeon) is an entry inhibitor and fusion inhibitor.
- Standard dose: 1 x 90 mg sub-cutaneous (under the skin) injection, twice-daily.
- Take with or without food.
- Side effects: injection site reactions, bacterial pneumonia, allergy.
- Other comments: T-20 is only used in people who have extensive drug resistance. Because of the inconvenience of a twice-daily injection, T-20 is rarely used for first combinations. Many people who relied on T-20 several years ago have been able to safely switch from T-20 to newer drugs that are active against drug-resistant HIV.
