What is the cap color of combination glaucoma drops?

Combination glaucoma drops commonly have a dark blue cap. This color coding is part of a system developed to help healthcare providers quickly identify the type of medication a bottle contains, especially when multiple eye drops are being prescribed. The dark blue cap specifically indicates that the bottle contains a combination of two or more drugs intended to reduce intraocular pressure in patients with glaucoma. This is important for ensuring safe and effective treatment, as it helps prevent confusion with other single-agent glaucoma medications, each of which has its own distinct cap color. Understanding this color coding can also aid patients in recognizing their medications, contributing to adherence to their prescribed treatment regimen.
