🔬 Product Description
Diphenhydramine Hydrochloride is a widely used first-generation antihistamine. It works by competitively blocking histamine H1 receptors, effectively alleviating symptoms caused by allergic reactions such as hives, skin itching, and allergic rhinitis. Furthermore, due to its pronounced central sedative and anticholinergic effects, it is also commonly employed to prevent and relieve motion sickness (e.g., carsickness, seasickness) and as a short-term sleep aid.
