they are safe to take together and you are correct. antibiotics may reduce the effectiveness of oral contraceptives so it would be wise to add another form of birth control until the antibiotic course has been completed.
is it safe to take cefdinir (antibiotic) and microgestin (birth control) together? . i recently got diagnosed with tonsillitis for the second time and was prescribed cefdinir as my antibiotic. but i am also on bcp. i know that antibiotics can reduce the efficacy of bcp but are there any other health effects i should know of?
