Hello, welcome to HCM. Excedrin
contains a combination of acetaminophen
, and caffeine. It doesnt contain penicillin as per your query. You must be allergic to one of the components of it. You should take a note of it and always tell your doctor in future before taling any medication. You can take tab cetrizine
twice daily till your symptoms get relieved or visit a doctor if symptoms persist for long. Wish you good health.
