chlorpheniramin

Chlorpheniramine is an antihistamine medication used to treat symptoms of allergies, the common cold, and hay fever. It works by blocking the effects of histamine, a natural substance the body produces during an allergic reaction. Histamine is responsible for symptoms such as itching, watery eyes, runny nose, sneezing, and hives.

It is available in various forms, including tablets, capsules, liquid suspensions, and nasal sprays. Chlorpheniramine is also often combined with other medications, such as decongestants and pain relievers, in over-the-counter cold and allergy remedies.

Common side effects of chlorpheniramine include drowsiness, dizziness, dry mouth, blurred vision, and difficulty urinating. It is important to avoid operating heavy machinery or driving until you know how this medication affects you due to its potential to cause drowsiness. Alcohol can increase these sedative effects.

Chlorpheniramine should be used with caution in individuals with certain medical conditions, such as glaucoma, an enlarged prostate, or thyroid problems. It is also not recommended for use in newborns or premature infants. Pregnant or breastfeeding women should consult a healthcare professional before using chlorpheniramine.

The dosage and duration of treatment depend on the specific condition being treated and the individual's response to the medication. It is typically taken every four to six hours as needed. Always follow the instructions provided by a doctor or on the product label.
