Chlorpheniramine Maleate

Chlorpheniramine maleate tablets are a great way to get relief from seasonal allergies and common cold symptoms. This antihistamine helps ease several allergy symptoms, including red, itchy, watery eyes, sneezing, throat irritation, and a runny nose caused by allergies and hay fever.

The medication comes in several forms—tablets, capsules, extended-release formulations, chewable tablets, and liquid—to match different patients' needs. Keep in mind that some people might feel sick, sleepy or dizzy while taking this medication. 

What is Chlorpheniramine Maleate?

Chlorpheniramine maleate blocks specific natural substances that cause allergy symptoms in the body. This first-generation antihistamine prevents histamine from binding to H1 receptors.

How Chlorpheniramine Maleate Tablets Work

When an allergen enters our system, our body releases histamine at the same time. Chlorpheniramine blocks histamine receptors, especially H1 receptors. Histamine normally connects to these receptors and causes sneezing, itching or watery eyes, which are usual allergy symptoms. Chlorpheniramine occupies these receptor sites and blocks histamine from binding. This action quickly alleviates those troublesome symptoms.
