This is a really tough topic because there are literally thousands of drug interactions and we honestly canât remember all of them. Enzyme inducers will increase the rate of metabolism of co-administered drugs and thus their effect will decrease or will be at lower therapeutic dose. As a result, the dose of such drugs (which are metabolized by microsomal enzymes) should be increased when administered along with enzyme inducers. google_alternate_ad_url = "http://www.rxpgonline.com/google_adsense_script.htm";
