What is a common side effect of glaucoma medication?

A common side effect of glaucoma medication can include red eye, which often occurs as a result of the active ingredients used to lower intraocular pressure. Many glaucoma treatments, particularly those that use medications such as prostaglandins or beta-blockers, can lead to increased blood flow to the conjunctiva (the membrane covering the eye), causing a reddening effect.

This side effect is usually mild and can vary depending on the type of medication prescribed and the individual’s response to it. While red eye may not pose a significant health risk, it can be a discomforting cosmetic concern for some patients, leading them to consider adjustments in therapy or alternative medications.

Other side effects, while possible, are generally not as specific or commonly associated with glaucoma treatments as red eye.
