Mixing CBD and your regular prescription medications is generally safe and interactions are often minimal or nonexistent. That said, there are some medications that require you to employ extra caution before starting to use CBD.
According to Harvard Medical School research, these medications included a thyroid medication called levothyroxine, multiple seizure medications including clobazam, valproate, and lamotrigine, a blood thinner called warfarin, and a heart rhythm medication called amiodarone. If you are taking any of these medications, it is even more important to talk to your doctor before starting to use CBD.
