What is the most important information for a client with glaucoma regarding over-the-counter (OTC) allergy medications?

For a client with glaucoma, the most crucial information regarding over-the-counter allergy medications is to avoid those that contain pseudoephedrine or phenylephrine. Both of these medications are decongestants that can lead to increased intraocular pressure, which is particularly concerning for individuals with glaucoma. This condition involves damage to the optic nerve often associated with high pressure inside the eye, and using decongestants can exacerbate this issue, potentially leading to vision loss or further complications.

Understanding the impact of key ingredients in allergy medications helps clients manage their condition effectively and avoid unnecessary risks. This knowledge empowers clients to make safe choices regarding their allergy treatment while considering their eye health.
