Is Claritin an Antihistamine?

When it comes to seasonal allergies, numerous medications promise relief from sneezing, itching, runny noses, and watery eyes. Among them, Claritin stands out as a popular choice for many. But what exactly is Claritin, and is it an antihistamine? Let’s dive in.

Is Claritin an Antihistamine?

What is Claritin?

Claritin is a brand name for the drug loratadine. It is an over-the-counter (OTC) medication widely used to treat symptoms of allergies such as hay fever, also known as allergic rhinitis. You might also find it in pharmacies to counteract symptoms from other allergens like dust mites, pet dander, and mold spores.

Is Claritin an Antihistamine?

Yes, Claritin is indeed an antihistamine.

How Do Antihistamines Work?

When your body encounters an allergen, it responds by releasing a substance called histamine. Histamine binds to receptors in various parts of your body, leading to allergy symptoms such as itching, swelling, runny nose, and watery eyes. Antihistamines, like Claritin, work by blocking these histamine receptors. By doing so, they prevent histamine from binding to the receptors and triggering these symptoms.

Benefits of Claritin:

  1. Non-Drowsy: One of the primary benefits of Claritin (loratadine) over some other antihistamines is its non-drowsy formula. Many first-generation antihistamines can cause drowsiness, but Claritin, being a second-generation antihistamine, typically doesn’t have this side effect when taken as directed.
  2. Long-Lasting: Claritin offers up to 24 hours of relief from allergy symptoms, which means it only needs to be taken once a day.
  3. Versatility: Apart from treating hay fever symptoms, Claritin can also help with allergic skin reactions, such as hives.

Considerations When Taking Claritin:

Always use Claritin as directed and discuss with a healthcare professional before starting any new medication. While Claritin is generally safe for most people, there can be interactions with other drugs or specific conditions where its use might not be recommended.


In the vast landscape of allergy medications, Claritin holds its place as a trusted non-drowsy antihistamine. It provides long-lasting relief from various allergic reactions and is a testament to the evolution of allergy medication, offering effective symptom relief without the drowsy side effects often associated with older antihistamines. If you’re considering an antihistamine, always consult with a healthcare professional to find the best fit for your needs.
