ZyrTEC-D: Cetirizine and Pseudoephedrine Combination for Allergy Relief

Introduction

ZyrTEC-D, also known as Cetirizine and Pseudoephedrine, is a combination drug used to help treat the symptoms of seasonal and yearly allergies. ZyrTEC-D combines an antihistamine (cetirizine) and a decongestant (pseudoephedrine) to help reduce allergies-induced watery eyes, tingling skin sensations, sneezing, runny nose, and itching. It is available in the United States in the form of an Extended Release Tablet.

What is Cetirizine and Pseudoephedrine?

Cetirizine is an antihistamine that blocks the effects of histamine, a naturally occurring substance in the body that causes many of the symptoms of allergies. According to the Mayo Clinic, histamine usually causes itchy eyes, sneezing, nasal stuffiness, or runny nose. Pseudoephedrine is a decongestant drug that clears nasal congestion but could raise blood pressure if taken by a patient with a history of hypertension.

How is ZyrTEC-D Taken?

ZyrTEC-D is an extended-release tablet taken orally, typically either once daily in the morning or in two portions (half in the morning and the other half 12 hours later). It is important to follow the instructions of your doctor or pharmacist closely when using this medication. Do not take more than the recommended dosage.

Side Effects

Potential side effects of ZyrTEC-D may include dizziness, headache, fatigue, drowsiness, or dry mouth. However, it should be noted that not all possible side effects are listed here. It is important to check with your doctor if you experience any unusual symptoms after taking ZyrTEC-D.

Who Should Not Take ZyrTEC-D?

ZyrTEC-D should not be used by anyone younger than 18 years old, as its safety and effectiveness have not been established in this age group. In addition, ZyrTEC-D should not be taken by people with high blood pressure, hypertension, glaucoma, heart disease, thyroid disease, or certain other kidney or liver ailments. Do not take ZyrTEC-D if you are pregnant or breastfeeding, or if you have taken a monoamine oxidase inhibitor (MAOI) in the last two weeks.
