Am trying to find out what the incubation period is for shingles. I had my first infusion of abatacept Friday before last. Second one is this Thursday. Am also on 20 mg methotrexate, plus hydroxychloroquine and amatripyline. I was told to avoid anybody with chickenpox or shingles. Unfortunately a friend I had dinner with 2 weeks ago has now been told she has shingles. I should add that I had chickenpox as a child and shingles about 15 years ago. It has taken me so long to get on to a biologic that I would be most upset if I had to delay it now. Not even sure what the problem is with shingles. If anybody has any experience of this I would very much welcome any advice.
