2.1 Dose Recommendations for Patients with Normal Renal Function
The recommended dose of SELZENTRY differs based on concomitant medications due to drug interactions (see Table 1). SELZENTRY can be taken with or without food. SELZENTRY must be given in combination with other antiretroviral medications.
Table 1 gives the recommended dose adjustments [see Drug Interactions (7.1)].
