Antibiotic and Trivora

I am taking Trivora (ortho tri cyclin) and I was recently on an antibiotic. I know this causes changes in protection, but I was wondering why. Does it change my cycle? Will I still have a period at the same time?

Thanks,

Hi Sarah, welcome!

Some antibiotics can alter the way some women metabolize the hormones in their pills (lowering the amount that gets into the bloodstream) thereby lessening the effectiveness of their protection. It’s not known how to tell who might be at risk which is why we recommend all OC users use back-up while taking antibiotics and for at least 7 days after taking the last dose of medicine. ABs might cause irregular bleeding in some women.

Thanks for stopping by.
