i recently started taking Clindamycin (300 mg/6 hrs) to prevent bacteria or infection. i had a chainsaw accident that resulted in 5 internal stitches and 10 external staples. i have now been on this medication going on 3 days. yesterday i had horrible heartburn and it became very hard to breathe as the day went on. i thought this was a result from the cause of change in diet and exercise from my injury (i smoke cigarettes). i began reading about this medication and found out these are symptoms and can be VERY SERIOUS. today i had been getting very dizzy after taking this medication and i assure this is not a result from the pain reliever in which i have taken many times in the past. i dont know what to do and am pretty nervous. the heartburn and chest pains are almost unbearable. please advise.
