Can The Effectiveness Of The Contraceptive Pill Be Affected By The Antibiotics?
Hi, I am currently on the birth control pill Gedaral and I m also taking a week s course of the antibiotic Trimethoprim to help clear up a urine infection. Two days ago I had unprotected sex and I was then told that the effectiveness of the pill can be affected by the antibiotics. I ve never missed a pill and always take them on time. Is there a chance that I may be pregnant?

Hi,
Yes, antibiotics can reduce the contraceptive effects. Antibiotics like trimethoprim may decrease the absorption of birth control pills and thus decrease their effectiveness in preventing an unwanted pregnancy. Therefore, the possibility of pregnancy can not be ruled out at this moment.
Hope I have answered your question. Let me know if I can assist you further.
