clorfeniramina

Clorfeniramina, also known as chlorpheniramine, is a first-generation antihistamine. It belongs to the alkylamine class of antihistamines. Clorfeniramina works by blocking the action of histamine, a substance produced by the body during an allergic reaction. Histamine is responsible for many of the symptoms associated with allergies, such as sneezing, itching, watery eyes, and runny nose.

This medication is commonly used to relieve the symptoms of hay fever, other upper respiratory allergies, and the common cold. It is effective in treating symptoms such as sneezing, itchy or runny nose, itchy, watery eyes, and itchy throat or nose. Clorfeniramina is also sometimes used to treat itching and swelling caused by hives and other allergic skin reactions.

Clorfeniramina is available in various forms, including oral tablets, capsules, syrups, and solutions. It is typically taken by mouth. Dosage and frequency depend on the age of the patient and the severity of the symptoms. It is important to follow the instructions provided by a healthcare professional or on the product label.

Like other first-generation antihistamines, clorfeniramina can cause side effects. The most common side effect is drowsiness, which can impair the ability to drive or operate machinery. Other potential side effects include dizziness, dry mouth, blurred vision, and difficulty urinating. It is advisable to avoid alcohol while taking this medication as it can increase drowsiness. Clorfeniramina should be used with caution in individuals with certain medical conditions, such as glaucoma, enlarged prostate, or thyroid problems.
