Will My Medicines Interfere With Raltegravir?
Theoretically, phenytoin may decrease the level of raltegravir in your blood, making it less effective. However, this interaction has not been adequately studied, so it is difficult to predict exactly how these medications will interact. Check with your healthcare provider before taking them together.
Proton Pump Inhibitors (PPIS)
PPIs may increase the absorption of raltegravir into your system. However, no dosage adjustment is recommended.
Tipranavir Combined With Ritonavir
Taking raltegravir with tipranavir and ritonavir can lower the level of raltegravir in your blood. However, studies have shown that these medications can usually be combined without making raltegravir less effective.
