While generally well tolerated, CBD can cause side effects such as dry mouth, diarrhea, reduced appetite, drowsiness and fatigue. It can also interact with medications, such as blood thinners. Another cause for concern is the unreliability of the purity and dose of CBD in products since they aren't regulated. CBD products can also be quite expensive.
The only CBD product approved by the Food and Drug Administration is a prescription oil called Epidiolex. It's approved to treat two types of epilepsy. Aside from Epidiolex, state laws on CBD vary.
If you plan to try products containing CBD, talk to your doctor about the benefits and risks. CBD oil isn't a solution on its own, and it shouldn't replace other recommended therapies. However, for some people, it may be part of a comprehensive symptom management strategy.
Yours in good health,
