Tell or Say, please, by what preparations contraceptive effect Marvelona can be weakened or easied? Whether can be those Nurofen, periodically accepted from menstrual pains? Or Pyrantelum accepted only once? Thanks!

Weaken or Easy contraceptive effect some antibiotics, antituberculous or antitubercular preparations, preparations for treatment of an epilepsy, adsorbents (the activated coal), slimming aids. Basically Nurofen and Pyrantelum effect OK do not reduce, but it is better to accept preparations not simultaneously, and with a difference at 3 o'clock.
