VICTRELIS Drug Interactions

Protease Inhibitors
Ritonavir has been shown to decrease VICTRELIS blood levels, potentially making it less effective. It is unknown if other protease inhibitors have the same effect on VICTRELIS. Talk to your healthcare provider before taking these medications together.
 
Additionally, VICTRELIS can lower the level of protease inhibitors in the blood, making them less effective. In general, such combinations are not recommended.
 
Rifabutin
Rifabutin can decrease levels of VICTRELIS in your body, potentially making it less effective. VICTRELIS may increase blood levels of rifabutin, potentially increasing your risk for side effects. It is recommended that these medicines not be used together.
 
Salmeterol
VICTRELIS may increase blood levels of salmeterol, possibly increasing your risk for potentially serious side effects, including heart rhythm problems. It is recommended that these medications not be taken together. Talk to your healthcare provider about this potential interaction before combining salmeterol with VICTRELIS.
 
Trazodone
Taking VICTRELIS with trazodone could increase the level of trazodone in your body, potentially increasing your risk for side effects, such as dizziness and low blood pressure. Your healthcare provider may need to give you a lower trazodone dosage while you take VICTRELIS.
 
Warfarin
VICTRELIS can have variable effects on warfarin, potentially increasing or decreasing warfarin blood levels. Your healthcare provider will likely monitor you more closely by checking your international normalized ratio (INR) if you take these drugs together.
