Zyrtec (cetirizine) is a second-generation antihistamine generally known for being well-tolerated, but it can still cause several, mostly mild, side effects. While it is marketed as a non-drowsy option, drowsiness is actually one of its most common side effects.

Additionally, as with many medications, it is metabolized by the liver and excreted by the kidneys, so these organs are involved in processing the drug.
Acute angle-closure glaucoma
Heavy caffeine intake should be advised against due to its transient elevations in IOP, especially in genetically predisposed patients or those with a positive family history of glaucoma. Chronic alcohol consumption can lead to many systemic complications and increased risk of glaucoma.
Blood pressure and eye pressure vary independently. Controlling blood pressure does not mean IOP is controlled. But studies have shown that patients with high blood pressure have an increased risk for glaucoma. Very high blood pressure is not good for glaucoma.
