this morning i went to my doctor for a perforated eardrum, horrible cough and general ague. she gave me some capsules which are purple and pink. on the front is A 15. She told me to take a probiotic? such as activia with them. at the time, i didn't think to ask why. the word on the envelope is amoxil. I also have an ear wash a little pink pill with west word 477 and benzonatate200 mg for cough. can you please explain? thank you
