When starting any new supplement, OTC, or other product (like CBD Oil), always discuss with your healthcare provider. Certain medications, like anticoagulants (ex. warfarin) and anti-epileptic drugs have a wide variety of drug-drug interactions due to their metabolism. These medications and others may have metabolic interactions with CBD that either preclude their use, or require extra monitoring. More information on if CBD is safe for you can be provided by your doctor, or local pharmacist.
