CTM is a medicine used to overcome the symptoms of allergies or allergic rhinitis. This medicine can relieve red and watery eyes, runny nose, sneezing, and itching in the skin, nose, eyes, and throat due to allergies. CTM is available in tablet form.

CTM contains chlorpheniramine maleate which inhibits the action of histamine, which is a compound that causes allergic symptoms when a person is exposed to an allergy trigger (allergen).

Keep in mind that this medicine cannot cure allergies. Therefore, allergy sufferers are still advised to avoid things that usually cause allergic reactions.

In addition to allergies, this medicine is also often used to relieve the symptoms of a runny nose, stuffy nose, or sneezing during the common cold .
