  • Timolol Maleate 0.5%, Ophthalmic drops, solution

    • Interaction: Marijuana
    • Severity: Major
    • Notes for Consumers: Marijuana can decrease the ability of this medicine to control your blood pressure and heart rate. You may need to monitor your blood pressure and heart rate more often to make sure they are well-controlled. If you check your own blood pressure at home and notice an increase in your blood pressure or heart rate, contact your health care provider.
    • Notes for Professionals: Avoid administering marijuana and beta-blockers together as concurrent use may result in decreased beta-blocker efficacy. Marijuana is known to produce significant increases in heart rate and cardiac output lasting for 2-3 hours. Further, rare case reports of myocardial infarction and cardiac arrhythmias have been associated with marijuana use. These marijuana-induced cardiovascular effects may be detrimental to patients requiring treatment with beta-blockers; thus, coadministration of beta-blockers and marijuana should be avoided.
