The interaction between CBD (cannabidiol) and blood pressure medications is a topic of growing interest and concern. While some studies and anecdotal evidence suggest CBD may lower blood pressure, it’s crucial to understand the potential risks and interactions, especially when combined with existing medications.

Potential Interactions
CBD can affect how the body metabolizes certain drugs. It can inhibit enzymes in the liver, potentially leading to increased levels of medications in the bloodstream. This could amplify the effects, both therapeutic and adverse, of blood pressure medicine. Some studies reported CBDs interaction with the immunosuppressant tacrolimus with 3-fold increase in dose-normalized tacrolimus concentrations.
Reported Effects of CBD on Blood Pressure
Some individuals have reported a decrease in blood pressure after taking CBD. For example, one person noted a drop from 147/98 to 125/82 in their left arm after 30 minutes of CBD use. However, these are individual experiences and not conclusive scientific evidence. It’s imperative to consult with a healthcare professional before using CBD, especially if you’re already on blood pressure medication.
Risks and Side Effects
CBD use carries some risks. Though its often well-tolerated, CBD can cause side effects, such as dry mouth, diarrhea, reduced appetite, drowsiness and fatigue. The unreliability of the purity and dosage of CBD in products is also a concern.
Recommendations
- Consult your doctor before using CBD with blood pressure medication.
- Start with low doses of CBD and monitor your blood pressure regularly.
- Be aware of potential side effects and interactions.
