Chlorphenamine

Chlorphenamine, also known as chlorpheniramine, is an antihistamine medication used to treat allergic symptoms such as runny nose, itchy eyes, and sneezing. It is a first-generation antihistamine, meaning it can cause drowsiness. It works by blocking the action of histamine, a substance in the body that causes allergic symptoms.

Chlorphenamine is available in various forms, including tablets, capsules, liquid solutions, and injectable forms. It is commonly found in over-the-counter cold and allergy medications, often in combination with other ingredients like decongestants or pain relievers. It is also available by prescription for more severe allergic reactions or other conditions.

The typical dosage of chlorphenamine varies depending on age and the specific formulation. It is important to follow the dosage instructions provided by a healthcare professional or on the product label. Side effects can include drowsiness, dizziness, blurred vision, and dry mouth. Due to its sedative effects, caution should be exercised when driving or operating machinery after taking chlorphenamine.

Chlorphenamine should be used with caution in individuals with certain medical conditions, such as glaucoma, prostate enlargement, or breathing problems. It may interact with other medications, including sedatives, tranquilizers, and alcohol, potentially increasing drowsiness. Pregnant or breastfeeding women should consult their doctor before using chlorphenamine.
