Understanding CBD and Omeprazole

As the popularity of cannabidiol (CBD) continues to grow, many people are interested in how it may interact with their current medications. One such medication is omeprazole, a common drug used to treat stomach and esophageal issues. It's crucial to understand the potential interactions between these substances before deciding to add CBD to your regimen. As always, it's recommended to consult with your healthcare provider before starting any new supplement, including CBD.

What is CBD?

CBD, short for cannabidiol, is a compound found in the cannabis plant. Unlike tetrahydrocannabinol (THC), the compound in cannabis that causes a "high," CBD is non-psychoactive. It's often used for its potential therapeutic benefits, including pain relief, anxiety reduction, and sleep improvement. CBD works in the body by interacting with the endocannabinoid system, a complex network of receptors that play a role in many bodily functions, including mood, appetite, and sleep.

What is Omeprazole?

Omeprazole, available under brand names like Prilosec (USA), Antra (Germany), and Omeprazol-ratiopharm (Germany), is a medication used to treat conditions caused by excess stomach acid. These conditions include gastroesophageal reflux disease (GERD), ulcers, and Zollinger-Ellison syndrome. Omeprazole works by decreasing the amount of acid your stomach produces, thereby relieving symptoms such as heartburn, difficulty swallowing, and persistent cough.

Potential Interactions between CBD and Omeprazole

There is currently limited research on the interactions between CBD and omeprazole. However, both CBD and omeprazole are metabolized in the liver by the same group of enzymes known as cytochrome P450 (CYP450). This means that CBD could potentially interfere with the metabolism of omeprazole, leading to an increase or decrease in the medication's effectiveness.

Moreover, both CBD and omeprazole can cause side effects. CBD side effects may include dry mouth, reduced appetite, drowsiness, and fatigue. Omeprazole side effects can include headache, abdominal pain, nausea, diarrhea, and vomiting. When taken together, these side effects could potentially become more pronounced.

Consulting a Healthcare Provider

Given the potential for interaction and the lack of comprehensive research on the subject, it's critical to consult with a healthcare provider before starting CBD if you're already taking omeprazole. Your healthcare provider can assess your individual health status and medication regimen to determine if CBD is a safe and beneficial addition.


In conclusion, while CBD has potential therapeutic benefits, it may interact with certain medications, including omeprazole. Due to the lack of extensive research, it's crucial to consult with a healthcare provider before adding CBD to your regimen if you're taking omeprazole. This will ensure that you can safely enjoy the potential benefits of CBD without risking unwanted side effects or interactions.
