I'm on the Yasmin combined pill. Recently I was prescribed

This answer was rated:

I'm on the Yasmin combined pill. Recently I was prescribed medicines for helicobacter pylori, these include clarithromycin,amoxicillin, Bismuth Potassium Citrate and Rabeprazole. I've been taking these medicines with Yasmin pills for a while, just wonder will they reduce the effectiveness of the pill?
Also, due to my stomach problem, I've experienced diarrhoea consistently in recent days. My doctor advised that some of the pills I've taken might not have been fully absorbed by my body. Therefore after sex with my boyfriend yesterday, I took a Levonelle pill as precaution. Will the medicines mentioned reduce the effectiveness of the Levonelle pill?
Thank you!
Welcome to and thank you for your question.
I am going to assist you with your question.
Well, Yasmin contains drospirenone and ethinyl estradiol. It is used as contraceptive to prevent pregnancy.
As such, according to studies, medicines used for treating H. Pylori infection would not have any negative interaction with Yasmin pills.
The effectiveness of Yasmin pill would remain same with use of Clarithromycin, Amoxicillin, Bismuth Potassium Citrate and Rabeprazole.
Having mild diarrhea or stomach pain, nausea are the common side effect of such medications given for treating H. Pylori infection.
Usually such side effect are mild, and would disappear by its own.
Levonelle contains levonorgestrel and is taken preferably within 12 hours and no later than 72 hours of unprotected sex.
As such you should not take Levonelle and continue with Yasmin pill, as advised by your doctor. You would be completely protected against pregnancy with such pill.
Good luck and take care.

Hi there.
Thank you for your question.
I will be helping you out with your queries.
I would like to add my opinion here.
Medications like clarithromycin and amoxicillin may reduce effecitivenss of ethinyl estradiol.
So I would not recommend using other contraceptives like a condom when one these pills.
Kind regards
Just a correction, I WOULD recommend using other contraceptive methods like condom when on these pills with yasmin.

Thank you very much, your answer is very helpful! I've received an answer from another doctor suggesting these medicines do not have effects on Yasmin, so I sort of get confused. Would you mind explain your opinion a bit further so that help me understand :)? Also, I have taken Levonelle as a precaution, will I be properly protected from pregnancy? (Will the antibiotics such as clarithromycin and amoxicillin reduce the effectiveness of Levonelle as well?)

Thank you!

Levonelle does not interact with any of the antibiotics that you are on. Actually you rated the other doctor therefore I did not get credit for it. I would appreciate it if you rate me again or post a new question directed to me on the following link:
