Ticarel Ticagrelor Ritonavir
MajorDo not take ticagrelor and ritonavir together. Ritonavir is a strong CYP3A4 inhibitor, and using them at the same time is contraindicated.
These medicines can affect each other in a serious way. Do not start taking them together unless your doctor has said it is OK. If you already take both, do not stop either one on your own: speak to your doctor or pharmacist soon.
