I am taking althea pill for my ovarian cyst , currently i m on my 2nd month. But I am planning to take Doxycyline for my pimples , will it affect the effectiveness of the oral contraceptive pill? And pls don t say that althea can help reduce my pimple, i know that, but i cant wait 3 months, it s getting worst, i could not stand it. Thanks for the answers.
