People considering consuming CBD products should always consult their doctor before doing so, especially if they are taking other medications or have underlying medical conditions, such as liver disease, kidney disease, epilepsy, heart problems, a weakened immune system, or if they are taking medications that can weaken the immune system. CBD has the potential to interact with many other products, including over-the-counter medications, herbal products, and prescription drugs. Some medications should never be taken with CBD; it may be necessary to modify or reduce the use of other medications to avoid serious problems. The consequences of drug interactions also depend on many other factors, such as the dose of CBD, the dose of another medication, and the person's underlying health condition.
Older adults are more susceptible to drug interactions because they often take several medications and because of age-related physiological changes that affect the way our bodies process medications. CBD can be harmful to the liver. People with liver failure should be careful or avoid it. A prescription cannabidiol (CBD) oil is considered an effective anti-seizure medication.
However, more research is needed to determine other benefits and the safety of CBD.
