Cannabidiol (CBD)
Recommendations
A pure CBD product, available by prescription only, reduces the number of seizures as well as their severity and frequency in adults and children taking other antiseizure drugs for one of 2 rare forms of epilepsy. Other effects of CBD have not been confirmed in high-quality studies in people. CBD can have side effects, such as dry mouth, low blood pressure, diarrhea, decreased appetite, mood changes, light-headedness, and sleepiness. However, serious side effects are rare, and CBD is probably safe for most people. Pregnant and breastfeeding women and people with liver disease, Parkinson disease, and men who want to have children should not take CBD. Taking CBD while taking other medications that can cause drowsiness or while drinking alcohol can cause extreme drowsiness, which could be dangerous. People who take drugs (including sedatives, antiseizure drugs, some antidepressants,valproic acid, and drugs to prevent the rejection of transplanted organs) should talk to their doctor before taking CBD. The regulations about CBD are complicated and confusing. If a person chooses to take CBD, they should buy the product from a medical dispensary and look for a "Certificate of Authenticity."
