Will My Medicines Interact With Fosamprenavir?

Some Statin Medications
Fosamprenavir should never be combined with lovastatin or simvastatin, due to the risk of dangerous side effects. Since fosamprenavir may increase the level of atorvastatin or rosuvastatin in your blood, your healthcare provider may recommend a lower dosage of these medications.
 
St. John's Wort
Because St. John's wort can greatly reduce the level of fosamprenavir in your blood, these medications should never be taken together.
 
Trazodone (Desyrel) or Trazodone ER (Oleptro) 
Fosamprenavir can increase the level of trazodone in your blood. Check with your healthcare provider before taking these medications together.
 
Tricyclic Antidepressants
Fosamprenavir can increase the level of tricyclic antidepressants in your blood, possibly increasing the risk of dangerous side effects. Your healthcare provider should monitor the level of tricyclic antidepressant in your blood and adjust your dose if necessary.
 
Warfarin
Fosamprenavir can interact with warfarin. Your healthcare provider may need to monitor you more closely and adjust your warfarin dosage as necessary.
