Beperidin is a medication that belongs to the class of antihistamines, specifically used to alleviate symptoms of Allergies and hay fever. It works by blocking histamine receptors, thereby reducing symptoms such as sneezing, runny nose, and itching. While it is effective for short-term relief, users should be aware of potential side effects, including drowsiness. Beperidin is not as commonly prescribed as other antihistamines and may have limited availability.
