Cytochrome P-450 is an internal system that breaks down, processes, and metabolizes many medicines. When it processes CBD, it slows down the processing of other medications. This can cause potentially dangerous levels of the drug to accumulate in your system.
To dive a bit deeper into how CBD interacts with the human body it’s necessary to look at a relatively obscure bodily system: cytochrome P-450. This internal system breaks down, processes, and metabolizes many medicines. One of the drugs this system interacts with is CBD.
When cytochrome P-450 processes CBD, it slows down processing other medications. Then, the unprocessed medicine sits stagnant in your body for longer than intended, causing potentially dangerous levels of the drug to accumulate in your system.
Medications given for chemotherapy also utilize the cytochrome P-450 system. If you’re currently undergoing chemotherapy, you should speak with your doctor to discuss any possible side effects of using CBD oil and methotrexate, paclitaxel, or etoposide.
