Good afternoon Dr.My husband had ear drum burst two days ago. We went to ER d/t severe pain. I requested Erythromycin ear drops, which on subsequent visit to ENT, specialist thought is was a great idea. I just noticed, prescription at hand is OPHTALMIC TOBRAMYCIN 0.3%. Pharmacy filled out according to what I can see, was the ARNP s Rx at ER. I just called Wallgreen s and they said that is fine to use on ear. What is your opinion, please? I m a nurse and I was trained not to confuse otic with ophthalmic. Thank you for your reply,Maria
