Enfuvirtide therapy requires twice-daily subcutaneous injection. It has not been shown to influence the metabolism of concomitant medications through the cytochrome P450 system.

Dose adjustments are not required in patients with renal insufficiency or mild-to-moderate hepatic insufficiency. Limited dosing data exist for patients with advanced liver disease; therefore, enfuvirtide should be used with caution in patients with hepatic decompensation. [8, 96]
