Pheniramine is a drug commonly used to treat symptoms of allergies, such as sneezing, itching, and watery eyes. It belongs to the class of antihistamines and is sold under various brand names. There are several synonyms for pheniramine, including Tripelennamine, Pyrilamine, Chlorphenamine, Clemastine, and Brompheniramine. These drugs work similarly to pheniramine by blocking histamine receptors in the body, which reduces the symptoms of allergies. While pheniramine is considered a first-generation antihistamine, newer drugs with fewer side effects have been developed, such as loratadine and fexofenadine. However, pheniramine is still a useful medication in certain situations, and its synonyms offer alternatives for people with allergies who need relief.
