Upsides and benefits Zyrtec Phenylephrine › Zyrtec (Cetirizine) works as well as other antihistamines to treat sneezing and runny nose, but causes less sedation. › Works well to also treat hives and itchy skin. › Zyrtec (Cetirizine) is available over the counter without a prescription. › It comes as a tablet, liquid, and quick-dissolving tablet. › It can provide quick relief of allergy symptoms for both kids and adults. › It's okay to take with most other medications because it has few drug interactions. › Most people don't get any side effects from Zyrtec (Cetirizine). › Works to clear nasal congestion and helps you breathe better. › Helpful in relieving congestion-related headaches. › Has fewer side effects than other decongestants like pseudoephedrine. › It doesn't raise your blood pressure and heart rate as much, or cause as much trouble falling asleep. › Doesn't give you rebound congestion (worse symptoms when you stop taking it) like nasal spray decongestants do.
