· Severity: Major

· Notes for Consumers: Discuss cannabis use with your care team. The effects of cannabis may be altered if used with your medication. Call emergency services right away if you experience slow or shallow breathing, shortness of breath, feeling faint, dizziness, confusion, or trouble staying awake.

· Notes for Professionals: Advise patients to avoid cannabis use during protease inhibitor treatment. Concomitant use may alter the exposure of some cannabinoids and increase the risk for adverse reactions. The cannabinoids delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD) are CYP3A substrates and protease inhibitors are strong CYP3A inhibitors. Concomitant use of a cannabinoid product containing THC and CBD at an approximate 1:1 ratio with another strong CYP3A inhibitor increased THC, 11-OH-THC, and CBD peak exposures by 1.3-, 3-, and 1.9-fold respectively.
