When I was growing up, I used to LOVE drinking Ruby Red Grapefruit Juice. It was my drink. Over the years, I have lost the taste of it like other foods and beverages that I used to enjoy when I was younger. Ruby Red and other grapefruit juices have a known effect on certain anti-seizure medications, specifically carbamazepine (Carbatrol/Tegretol). I take carbamazepine twice a day, 200 mg tablets. I actually didn’t have a clue in the world that there was a negative drug interaction between grapefruit juice and carbamazepine. With grapefruit juice, chemicals in the fruit interfere with the specific enzymes that are needed to break the medication down in the body. As a result, this leads to higher blood levels of the medications causing serious side effects. That can be a dangerous situation. The juice, along with the grapefruit contain these chemicals.
If you or someone you know has epilepsy, take your diet into consideration when taking anti-seizure medications. Always talk to a physician first about any concerns.
