Does antibiotics kind birth control not work?
Answers: Some antibiotics do hold the ability to interfere near birthcontrol. I don't think that 1 pill however will override the effect of 11 mo. of birthcontrol. For adjectives reference, double up on the birthcontrol if your gf wants to be on an antibiotic.
There is one known antibiotic (Rifampin) that in fact interferes with birth control. It doesnt issue if shes been on it for 11months. However, near are some studies that say taking adjectives antibiotics (ie amoxicillin etc) MAY decrease birth control worth. yes its true that antibiotics will cancel out birth control. if your girl friend have to take an antibiotic she desires to make it prearranged to her doctor or dentist that she is on birth control so maybe they can work out a non conflicting medication for her. contained by the mean time, the two of you should appropriate extra precaution during sex such as condoms or spermacide. hope this helps.
antibiotic doesn't interfere beside birth control as long as she taking it regularly
