Does CBD Interact with other drugs: What to look for and how to take CBD with other medications?

With an increase in the awareness about cannabis, hemp and marijuana, people are becoming more and more aware of Cannabidiol, popularly known as CBD, and its many benefits. This cannabis compound has a number of therapeutic qualities, which have made CBD-rich products – for example, tinctures, oils or capsules – very popular amongst people. In addition to the benefits, the chances of something going wrong are also pretty low, making this a great option for people trying to treat an ailment that has previously shown to benefit from the use of CBD. There is, however, one aspect that is not given its due when it comes to CBD and that is the cannabis compound’s interaction with other drugs.

Can CBD Interact with Other Drugs?

The simple answer to this question is yes. Your body will metabolize CBD in a manner that may positively or negatively interfere with the way other drugs are metabolized. If the body isn’t able to metabolize the other drugs in a good enough manner, it can lead to a buildup of the drugs in your system and eventually cause some side effects or complications. As a basic rule,to find out if your drugs could interact with CBD check for a grapefruit warning on your medication. 

Finally, keep in mind that the drug interactions can also be a positive thing in some cases, where the CBD makes the other drugs even more effective than they would have been without CBD. In such cases, it is possible to reduce the dosage of these drugs, if used in combination with CBD – but you must consult a medical professional before taking such a decision.

A good example of a drug that could show some negative side effects upon interacting with CBD is warfarin or any other blood thinner, these are know to have increased potency when taken with grapefruit or CBD. 

Grapefruit Interaction Warning

This may seem like an odd warning when thinking about taking CBD, but it really isn’t. A number of physicians tell their patients to avoid grapefruit when they are on different types of medications and there is a valid reason for that. The consumption of grapefruit releases some compounds that can inhibit the cytochrome P450 system of your body, in a way that is similar to CBD.

This system is the part of your liver that is in charge of metabolizing almost three-fifths of all the pharmaceutical drugs that can be acquired in the market. The cytochrome P450 system is made up of over 50 enzymes that are responsible for processing and eliminating different toxins in your body. You must keep in mind that CBD can be a more potent inhibitor but if your doctor or physician has warned you against consuming grapefruit, it is highly likely that CBD oil must also be avoided with the medication.

To check if your medication carries a grapefruit warning you can ask your Doctor, Check the side-effects and warnings section of the leaflet issued with your medication or visit Drugs.com to check if your medication is listed under the interactions list. 

While this is a good way to ascertain when to avoid CBD, it is recommended that you talk to your doctor about it.
