minor Known Drug Interaction
Asymptomatic bradycardia (36 beats/min) with a wandering atrial pacemaker has been observed in a patient receiving concomitant timolol (a beta-adrenergic blocker) eyedrops and oral verapamil.
No summary available.
Verapamil is a drug that helps to lower blood pressure and treat chest pain (angina) and irregular heartbeats (arrhythmias). It works by relaxing blood vessels and slowing down the heart rate.
Information not available.
Verapamil is used to treat chest pain called angina. This includes angina that happens when you are resting or during normal activity. It is also used to control your heart rate if you have a fast or irregular heartbeat, such as atrial fibrillation or atrial flutter. Verapamil also treats high blood pressure.
Information not available.
Verapamil belongs to a class of drugs called calcium channel blockers. It works by blocking calcium from entering heart and blood vessel cells. This relaxes and widens blood vessels, which lowers blood pressure and makes it easier for the heart to pump.

How to Read This timolol vs verapamil Comparison
timolol is classified in the Beta-Blocker (Ophthalmic) drug class, while verapamil sits within the Calcium Channel Blocker class. Drugs from different classes work through distinct mechanisms, so a head-to-head comparison illustrates trade-offs rather than equivalence. Both drugs are prescription-only, so a licensed provider must authorize use.
Adverse event totals above are pulled from the FDA's Adverse Event Reporting System (FAERS). For these top-ranked reactions alone, timolol has 4,765 submissions while verapamil has 1,579. Those figures reflect cumulative reporting volume, not per-patient risk, so older, widely dispensed drugs typically look worse on count alone. These two drugs have a known minor interaction flagged in FDA labeling, attributed to even as eye drops, timolol can combine with verapamil to significantly slow down your heart rate.. Serious warnings, pregnancy guidance, and contraindications can differ even when indications overlap.
A table cannot represent individual circumstances. Data here is sourced from FDA Structured Product Labels (SPL) and FAERS, both of which update as manufacturers and clinicians submit new information. This registry does not provide medical, treatment, substitution, or medication-change directions for timolol or verapamil.
