In theory, some of those drugs could flip from therapeutic to toxic if CBD caused them to build up. Cannabis products are compounds derived from the cannabis plant. These products are being used with increasing frequency in the treatment of epilepsy and other chronic diseases. While generally felt to be safe due to their natural origin, data reveals interactions with other pharmaceuticals.
Despite its many medical benefits, patients should proceed with caution as cannabis does have side effects, and it can also interact with other drugs. While more conclusive research is ultimately needed before we can determine the full extent of the plant’s drug interactions, researchers have already identified several common ones. If you are considering using CBD oil to manage epilepsy symptoms, please speak with your doctor first. Beta blockers are often prescribed to treat individuals with anxiety, high blood pressure, or other heart conditions, so you might wonder if CBD may enhance the effectiveness of these medications. However, because CBD affects the metabolization of these drugs, your blood pressure may drop too much if they’re taken together.
If you notice unexpected effects, consider talking with your doctor about other treatment options or ways to decrease their intensity. Researchers also suggest that the anxiety- and stress-reducing properties of CBD may contribute to the overall ability to lower blood pressure. However, CBD taken with blood pressure medication or beta-blockers could potentially cause both drugs to double up on each other and lower blood pressure to unhealthy levels. No studies have examined potential interactions between CBD and metoprolol.
This case outlines one such example in a patient taking warfarin (a commonly used blood thinner). Following the addition of cannabidiol, the patient’s INR (international normalized ratio, a marker of the blood-thinning effect of warfarin) exceeded the therapeutic range. This case underscores the importance of proper monitoring in patients taking warfarin and cannabis derivatives. While most people experience little to no side effects from CBD, it’s important to be aware of the risks involved before you start your treatment. Without this information, people may not realize that hemp hemp oil for sale oil is the cause, or they may think that a symptom is being caused by the product when it’s actually something else.
Your heart rate may slow further, as well, and you might experience other side effects of the medication—such as feeling weak or dizzy. Devitt-Lee notes that most medications are safe enough that, even if they built up in our bloodstream, they’d still provide their intended benefits and, at worst, possibly risk a few more benign side effects than usual. The real concern, he explains, is drugs that are only useful in narrow dosages, below which they have no real effect and above which they may be toxic, and drugs that are already administered at high doses.
