I am 5 almost 6 weeks pregnant and had been suffering with a sinus infection up until Wednesday just gone. I had it for about 4 weeks and it was pretty bad. So the previous Wednesday I had had enough as it wasn't getting better so I went to the doc, told her I was 4 weeks pregnant and she gave me a prescription for Erythromycin. Her system said that was the drug to give when pregnant. I'm not allergic to penicillin. Anyway, I took the 5 day course and finished on Monday just gone. Then the next day it is in the paper and there has been a study done by the BMJ comparing the use of erythromycin to penicillin in early pregnancy and how there is an increased risk in cardiac defects and erythromycin should be used with caution. This was very upsetting to read, and more upsetting because I could have had penicillin. I know the risk is still low but I feel cross because its added more anxiety to an already nerve-wracking time. On further research there are quite a few studies done before this recent study that have found a link between erythromycin and cardiac defects so it is not necessarily new evidence either. Would like to hear how other people feel about this?
