Allergy season can be tough, with symptoms like sneezing, itchy eyes, and a runny nose getting in the way of daily life. Many people want an antihistamine that works well without making them feel sleepy.
Zyrtec and Claritin are both popular second-generation antihistamines that promise allergy relief with fewer sedative effects compared to older options. However, not everyone finds these medications to be the perfect fit for their needs.
In this article, we’ll take a closer look at how Zyrtec and Claritin compare, including their benefits and potential drawbacks. We’ll also discuss an alternative option that could provide better relief for those who find these two antihistamines less effective.
What is Zyrtec?
Zyrtec is an antihistamine used to relieve nasal symptoms such as sneezing, congestion, and a runny nose caused by allergies. Its active ingredient, cetirizine, works by blocking histamine to offer fast relief for allergy symptoms [*].
While Zyrtec is available in various forms, including chewable tablets, liquid gels, and syrup (for children), its most common form is a tablet. According to the website, this prescription-strength allergy medicine starts working within one hour.
This makes Zyrtec a popular choice for those seeking effective allergy symptom management.
What is Claritin?
Claritin is a non-drowsy antihistamine that contains loratadine, which blocks histamine, the chemical that causes allergy symptoms. It helps relieve sneezing, runny nose, and itchy or watery eyes, which is an option for allergy relief without causing sleepiness. Loratadine is long-acting, meaning it also provides extended relief throughout the day [*].
In addition to its standard tablet form, Claritin is available in several other formulations, including melt-in-your-mouth tablets, liquid-filled capsules, chewable tablets, and a cooling honey-flavored oral solution. These options make Claritin convenient and easy to take for various preferences.
