Longifene Syrup contains Buclizine hydrochloride 6mg per 5ml and is indicated for the management of nausea, vomiting, and motion sickness. Buclizine is an antihistaminic agent with anticholinergic and antiemetic properties, acting centrally on the vomiting center in the brain to alleviate symptoms associated with vestibular disturbances and gastrointestinal irritation. This syrup formulation allows for easy administration, particularly in pediatric and geriatric populations. Longifene Syrup is effective in preventing and treating nausea and vomiting caused by motion sickness, vertigo, and other vestibular disorders. The recommended dosage should be adhered to as per physician guidance, with caution advised in patients with a history of hypersensitivity to Buclizine or other antihistamines. Use is contraindicated in individuals with glaucoma, peptic ulcer, or severe liver impairment. Common adverse effects may include drowsiness, dry mouth, and occasional gastrointestinal discomfort. Patients should avoid activities requiring mental alertness, such as driving or operating machinery, until the effects of the medication are known. Longifene Syrup should be stored at room temperature, protected from light and moisture. Consultation with a healthcare professional is essential before initiating therapy to ensure appropriate use and to minimize potential drug interactions.
