Serious. These medicines may interact and cause very harmful effects. Contact your healthcare professional (e.g. doctor or pharmacist) for more information.
How the interaction occurs:
Protease inhibitors may slow down how quickly your body processes cyclosporine, sirolimus, tacrolimus, or temsirolimus.
What might happen:
The amount of cyclosporine, sirolimus, tacrolimus, or temsirolimus in your body may increase and cause more side effects than normal.
What you should do about this interaction:
Let your healthcare professionals (e.g. doctor or pharmacist) know that you are taking these two medicines together. Your doctor may want to check the amount of medicine in your blood.Contact your healthcare professional if you experience any chest discomfort, dizziness, shaking, leg cramping, swelling, or any unusual stomach upset, headache, or skin irritation.Your healthcare professionals may already be aware of this interaction and may be monitoring you for it.
