Important safety information
PREZISTA does not cure HIV infection or AIDS, and does not prevent passing HIV to others.
PREZISTA is contraindicated in patients with known hypersensitivity to any of its ingredients.
Coadministration of PREZISTA/r is contraindicated with drugs that are highly dependent on CYP3A for clearance and have a narrow therapeutic index (e.g., astemizole, terfenadine, dihydroergotamine, ergonovine, ergotamine, methylergonovine, cisapride, pimozide, midazolam, or triazolam) and for which elevated plasma concentrations are associated with serious and/or life-threatening events. Coadministration is not recommended with carbamazepine, phenobarbital, phenytoin, rifampin, lopinavir/ritonavir, saquinavir, lovastatin, pravastatin, simvastatin, or products containing St. John's wort (Hypericum perforatum).
Caution should be used when prescribing agents such as sildenafil, vardenafil, tadalafil, or other substrates, inhibitors, or inducers of CYP3A in patients receiving PREZISTA/r. This list of potential drug interactions is not complete.
PREZISTA must be co-administered with 100 mg ritonavir and food to exert its therapeutic effect. Failure to correctly administer PREZISTA with ritonavir and food will result in reduced plasma concentration of PREZISTA that will be insufficient to achieve the desired antiviral effect. Please refer to ritonavir prescribing information for additional information on precautionary measures.
Severe skin rash, including erythema multiforme and Stevens-Johnson
Syndrome, has been reported in subjects receiving PREZISTA during the
clinical development program. In some cases, fever and elevations of
transaminases have also been reported. In clinical trials (n=924), rash
(all grades, regardless of causality) occurred in seven percent of subjects
treated with PREZISTA; discontinuation due to rash was 0.3 percent. Rashes
were generally mild-to-moderate, self-limiting and maculopapular. PREZISTA
