Detailed Information

Contraindications

**Contraindications** Hypersensitivity to darunavir or to any of the excipients. Darunavir and ritonavir are both inhibitors of the cytochrome P450 3A (CYP3A) isoform. PREZISTA®/rtv should not be co-administered with medicinal products that are highly dependent on CYP3A for clearance and for which increased plasma concentrations are associated with serious and/or life-threatening events (narrow therapeutic index). Examples include alfuzosin, astemizole, cisapride, colchicine (in patients with renal and/or hepatic impairment), dapoxetine, dronedarone, elbasvir/grazoprevir, the ergot alkaloids (e.g., ergotamine, dihydroergotamine, ergonovine and methylergonovine), ivabradine, lomitapide, lovastatin, lurasidone, midazolam (oral), naloxegol, pimozide, ranolazine, sildenafil (when used for treatment of pulmonary arterial hypertension), simvastatin, terfenadine, ticagrelor, and triazolam (see _Interactions_ – _please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information_). Patients taking PREZISTA® should not use products containing potent CYP3A inducers such as rifampin or St. John’s wort because co-administration may result in reduced plasma concentrations of darunavir. This may result in loss of therapeutic effect and development of resistance.
