Can Macrobid Be Used As A Substitute For Penicillin?

I am having a mild reaction to penicillin (2 doses in) for strep throat. Itchy eyes and wheezing. Have taken an antihistamine and am in no danger but will discontinue the penicillin use. I have an unused prescription of Macrobid for chronic UTI on hand. Can I substitute it for the penicillin until I get to see a doctor on Tuesday?

Dear thanks for the question.

Yes you can use macrobid for strep infections. Macrobid is also equally effective. So stop penicillin as you are allergic to it. By Tuesday you will be fine, may not require a doctor's visit. Keep taking antihistamines along with it.

I hope my reply will benefit you. Please write to HCM for follow up queries. I wish you rapid recovery and good health. Hit a thanks. Thank you
