Drug or food interactions
Ocular beta-blockers may have additive effects when used with oral beta-blockers. Additive effects occur when used with other drugs that lower intraocular pressure.
Beta-blockers may contain sulfites, which may cause allergic-type reactions. Rarely, use may worsen or cause symptoms observed with orally administered beta-blockers, such as heart disturbances (abnormal heart rhythm, heart attack, or heart failure), asthma, chronic obstructive pulmonary disease, or mental changes (especially in elderly persons).
