Macrobid And Longterm Heart Palpitations (Page 2)
(Newest replies first)

I was prescribed Macrobid 4 times a day for 14 days back in June 2015. After 10 days my heart was racing , I had a headache so bad it felt like my brain was swelling. After reading some blogs and seeing what other folks were experiencing I quit taking them on day 10. I am still having severe palpitations 3 months later and feeling my heart skipping beats. Until the Macrobid I have never had this happen. I recently was put on a 24 hour heart monitor and it only worked for 14 hours before it errored. When they downloaded the recording it showed I had over 5000 incidents in the 14 hours. I'm scheduled now for an echo cardiac ultrasound in 3 days and my physician wants to put me on a low dose beta blocker. I feel nervous about the beta-blocker so am waiting til the ultrasound. My question I guess is "has anyone else had a longterm effect [3 months] with heart palpitations after taking high doses of this antibiotic '?

Hi, have your heart palpitations went away? I am pregnant and I was prescribed macrobid 100mg twice a day for 7 days for Uti. In the evening of day 4 I had a palpitations. I checked side effects over and over but couldn't find heart problems on the list. So I kept taking the pills day 5 and in the evening my heart was beating so fast I couldn't leave the bed. I was really scared. I think I just have my last pill today. Please, let me know if docs found that your palpitations were linked to macrobid and if you feel any better?

Hello, Melinda! How are you?

No, that's not listed among the side effects provided by the FDA.

There can be some EKG changes, while you're on it, and the headaches are also normal. Other typical side effects usually include nausea, dizziness and diarrhea.

Has anyone else whose taken this medication experienced this?
