My husband is taking oral crizotinib and is shortly going to have a tooth extracted. He will probably need antibiotics afterwards but we are worried about which one he will be able to have whilst taking crizotinib as we understand that a lot of antibiotics interact with this drug. Also to make things more difficult he is allergic to penicillin!! We will talk to our oncologist at our next appointment but wondered if anyone had been in this situation or has any advice. Thanks for taking the time to read this.
