What is Chlorpheniramine (antihistamine)?
Chlorpheniramine, also known as chlorphenamine, is an antihistamine medication used to relieve allergy symptoms such as itching, sneezing, and runny nose. It works by blocking the action of histamine, a chemical released during an allergic reaction, thereby reducing swelling, redness, and other symptoms associated with allergies. Chlorpheniramine can be found in various forms, including tablets, capsules, and liquids, and is often used to treat conditions like hay fever, dust mites, and other environmental allergies.
What is Chlorpheniramine (antihistamine) used for?
Chlorpheniramine, also known as chlorpheniramine maleate, is a first-generation antihistamine that has been widely used for many years. It belongs to the class of medications called anticholinergics and antihistamines, which work by blocking the action of histamine, a naturally occurring chemical in the body. Histamine plays a key role in allergic reactions, and when it binds to its receptors on blood vessels, it causes them to become inflamed and swollen.
Chlorpheniramine is used to relieve symptoms of various conditions, including hay fever (allergic rhinitis), itching, runny nose, sneezing, watery eyes, and hives. It works by drying up the nasal passages and reducing the amount of mucus produced, thereby providing relief from respiratory symptoms associated with allergies. Additionally, chlorpheniramine can also be used to treat other conditions such as itching and redness caused by urticaria (hives), sunburns, insect bites, and minor skin irritations. However, it is essential to use this medication under the guidance of a healthcare provider due to its potential side effects and interactions with other medications.
