Potential Side Effects of Using CBD Oil

Understanding CBD

We’ve covered the potential benefits of using CBD oil, but what are the side effects?

This is a common, and important question that we’ll answer in this blog. 

It should be noted that the research on how CBD impacts the human body is ongoing, and all of the information detailed in this blog is current, as of 2021.

CBD and Its Interaction With Other Medicines

The first thing you should consider before you start taking CBD Oil is how it may work alongside your other medications. Although research shows that CBD is a safe product – broadly speaking, one can never be too safe.

A major factor you must consider is that taking CBD products will cause your body to produce cytochromes, an enzyme that may influence a person’s response to commonly prescribed drugs like antidepressants.

Another example: if you’re taking blood-thinning medication, taking CBD might impact the efficacy of the medication.

As a first step, look for a “grapefruit warning” on your prescription. This warning is used because grapefruit will actually impact the body in a similar way to CBD.

To be safe, always consult your doctor. 

Other Potential Side Effects You May Experience When Using CBD Products

Outside of the potential side effects you may experience when using CBD alongside prescription medications, some people (a very low percentage) have reported other side effects, such as:

  • Weight changes
  • Fatigue
  • Diarrhea

It should be noted that most experts believe that using CBD products is safe and the above side effects are rare.


You never know how your body may react to something new, so it’s best to take CBD in small doses, to begin with, or consult your doctor if you have any concerns.
