Introduction

Chlorphenamine 4mg Tablets are a sedating antihistamine used to treat a range of allergic conditions including hayfever, skin rashes, hives, insect bites, and allergic rhinitis. Each tablet contains 4mg of chlorphenamine maleate, a trusted active ingredient that effectively blocks histamine—an immune chemical responsible for allergy symptoms.

These tablets offer fast relief from itching, sneezing, runny nose, and swelling, making them suitable for both seasonal and year-round allergies. They are also effective for allergic skin conditions and mild reactions to foods and medications.

How It Works

Chlorphenamine belongs to the first-generation class of antihistamines. It works by blocking H1 histamine receptors in the body, preventing the effects of histamine during an allergic reaction. This helps to reduce inflammation, swelling, itching, and other allergic responses.

Because it is a sedating antihistamine, it can also have a mild calming effect—making it useful at night when allergies interfere with sleep.

Why Choose Chlorphenamine 4mg Tablets

These tablets provide broad-spectrum allergy relief and are a reliable choice for those dealing with both acute and persistent allergic conditions. They are ideal for use when non-drowsy antihistamines are ineffective or when calming, sleep-supporting effects are also needed.

Available without a prescription, Chlorphenamine Tablets are convenient and cost-effective, making them a staple in many households. The compact packaging also makes them easy to store and carry when needed.

Chlorphenamine may cause drowsiness. Do not take with alcohol or other sedatives. Avoid driving or operating machinery after taking a dose. Do not use if you have glaucoma, prostate enlargement, or are taking MAOIs. Store in a cool, dry place below 25°C. Keep out of reach of children.
