Examining Cannabinoid Effects on Rx Medications

A recent study in Pharmacy Times examines the altering effects of cannabinoid-containing products on some prescription drugs.

The study, which was published by Penn State College of Medicine, contains a list of 57 medications that may not function as prescribed when used with medical cannabinoids or CBD oil and medical or recreational marijuana.

In the study, researchers examined the prescribing information for four prescription cannabinoids and a list of enzymes in the body that process the active ingredients in those medications, which may include THC and CBD.

They then compared those findings with the prescribing information from common medications using the FDA and other regulatory agencies as resources to identify drug-drug interactions.

The subsequent list contains a variety of drugs, from antibiotics to antifungals and more.

When prescribing medications to patients, the study suggests asking patients about cannabinoid-containing product use and to help ensure the utmost safety and effectiveness of the medication.

A comprehensive list of 139 medications that may be affected by concurrent cannabinoid use is available for reference online.
