Bredicon Drug Interactions

Tell the doctor or pharmacist if taking, have recently taken or might take any other medicines or herbal products. Also tell any other doctor or dentist who prescribes another medicine (or pharmacist) that Bredicon is being taken. They can tell if additional contraceptive precautions (for example condoms) need to be taken and if so, for how long or whether the use of another medicine needed must be changed.
Some medicines: can have an influence on the blood levels of Bredicon; can make it less effective in preventing pregnancy; can cause unexpected bleeding. These include medicines used for the treatment of: epilepsy (e.g. primidone, phenytoin, carbamazepine, oxcarbazepine, felbamate, topiramate and phenobarbital); tuberculosis (e.g. rifampicin, rifabutin); HIV infections (e.g. ritonavir, nelfinavir, nevirapine, efavirenz); Hepatitis C virus infection (e.g. boceprevir, telaprevir); other infectious diseases (e.g. griseofulvin); high blood pressure in the blood vessels of the lungs (bosentan); depressive moods (the herbal remedy St. John's Wort); certain bacterial infections (e.g. clarithromycin, erythromycin); fungal infections (e.g. ketoconazole, itraconazole, fluconazole); high blood pressure (hypertension), angina or certain heart rhythm disorders (e.g. diltiazem).
If taking medicines or herbal products that might make Bredicon less effective, a barrier contraceptive method should also be used. Since the effect of another medicine on Bredicon may last up to 28 days after stopping the medicine, it is necessary to use the additional barrier contraceptive method for that long. The doctor can tell if additional contraceptive precautions need to be taken and if so, for how long.
Bredicon may also interfere with how other medicines work, causing either an increase in effect (e.g. medicines containing cyclosporine) or a decrease in effect (e.g. lamotrigine).
Ask the doctor or pharmacist for advice before taking any medicine.
