Hi,my husband, 65 yrs old, excellent health, only takes 20 mg Simvastatin nightly, noticed red circles on his arm, about two, then just tonight noticed one on his chin......they look like the red spots one gets on their arms from being on Coumadin!  Were not the worry type, will the disappear in time?Thank You so much!Michelle
Hello, Thanks for the query, It looks like he is developing an allergic reaction to the Chat Doctor. This must be suspected as he has a history with use of Coumadin. This is a matter of concern. Let me know you have any other doubts. Please meet a dermatologist for exact diagnosis. You can ask a direct question to me on this forum, following the below link.https
