A member asked:
Does sulfameth interfere with birth control? back up protection failed so i don't know if i should take plan b or would that be effective?
A doctor has provided 1 answer
FERTILITY CONTROL: Sulfa rx does not interfere with bcp.Plan b or Provera (medroxyprogesterone) rx to bring down menstruation is safer if pregnancy test is negative under the guidance of your gyne.
