A member asked:
Can macrobid help with cold sores if taking it and a cold sore breaks out?
A doctor has provided 1 answer
Sorry, no: Cold sores are usually caused by viruses. Macrobid is an antibiotic, which only helps with bacteria. it will not be likely to affect the cold sores or make them go away any faster. Usually the best bet is to just wait them out. Good luck.
