Cybelle Drug Interactions

Some medicines may stop Cybelle from working properly. These include medicine used for the treatment of epilepsy (eg, primidone, phenytoin, barbiturates, carbamazepine, oxcarbazepine, topiramate, felbamate), tuberculosis (eg, rifampicin, rifabutin) and HIV infection (nelfinavir, nevirapine, efavirenz); some antibiotics (eg, ampicillin, tetracyclines) and antifungal (griseofulvin) for some other infectious disease, and herbal medicines containing St. John's wort.
Cybelle may also interfere with the working of other medicines (eg, cyclosporine, lamotrigine).
Inform the doctor or pharmacist if the patient is taking or have recently taken any other medicines or herbal products, even those not prescribed. Also tell any other doctor or dentist who prescribes another medicine (or the dispensing pharmacist) that the patient uses Cybelle. The doctor or pharmacist can tell if the patient needs to take additional contraceptive precautions and if so, for how long.
