How soon after using metronidazole vaginal gel (0.75%) for bacterial vaginosis can you consume alcoholic beverages? On the box it says do not drink alcoholic beverages when taking this medicine. I only used it twice, and experienced bad side effects so I do not plan on using it anymore. Today (April 22), was the last time I used it. Will I be able to drink alcohol on Saturday, April 25? Thank you.
