Immune reconstitution syndrome

This may occur in Danavir 600mg therapy; to overcome the problem therapy should be discontinued.

CONTRAINDICATION

Combination of Danavirwith ritonavir are mostly based on CYP3A for clearance and increased plasma concentration causes life threatening reactions similarly with interaction with Alfuzosin cause hypotension Concomitant use with Dihydroergotamine causes peripheral vasospasm sand ischemia.

Danavir combination withCisapride andpimozide causes cardiac arrhythmias Interaction of Midazolam and triazolam causes respiratory depression.
