Key takeaways

Zyrtec-D (cetirizine/pseudoephedrine) and phenylephrine eye drops are used for different purposes and have distinct characteristics. Zyrtec-D is a combination of an antihistamine (cetirizine) and a decongestant (pseudoephedrine) that helps relieve seasonal allergies and nasal congestion. It's taken orally and is available over the counter. Zyrtec-D may cause trouble sleeping and a temporary rise in blood pressure. On the other hand, phenylephrine eye drops are used to dilate pupils for eye exams or procedures. This medication is an alpha-1 adrenergic receptor agonist and is available only by prescription. It can cause temporary eye discomfort, blurry vision, and sensitivity to light, and it may also raise blood pressure, especially in higher concentrations.
