I was doing some research on Ovcon-35 and I came across a site with drug information and it says that these things interfere with my bc:
•antibiotics or medicines for infections, especially rifampin, rifabutin, rifapentine, and griseofulvin
•aprepitant
•barbiturate medicines for producing sleep or treating seizures (convulsions)
•bosentan
•carbamazepine
•caffeine
•clofibrate
•cyclosporine
•dantrolene
•grapefruit juice
•hydrocortisone
•medicines for anxiety or sleeping problems, such as diazepam or temazepam
•medicines for mental depression
•medicines for diabetes, including troglitazone and pioglitazone
•mineral oil
•modafinil
•mycophenolate
•nefazodone
•oxcarbazepine
•phenytoin
•prednisolone
•ritonavir or other medicines for the treatment of the HIV virus or AIDS
•selegiline
•soy isoflavones supplements
•St. John's wort
•tamoxifen or raloxifene
•theophylline
•topiramate

Is this true? Has anyone else heard of caffeine and grapefruit juice interacting with bc?
