Hyokof Flu Syrup Orange is a combination oral medication formulated to provide symptomatic relief from common cold and flu symptoms. Each 5 ml contains Chlorpheniramine Maleate 2 mg, an antihistamine that alleviates allergic manifestations such as sneezing, runny nose, and watery eyes by blocking histamine H1 receptors, and Phenylephrine 5 mg, a selective alpha-1 adrenergic receptor agonist that acts as a decongestant to reduce nasal mucosal swelling and congestion. This dual-action syrup is indicated for the management of nasal congestion, rhinorrhea, sneezing, and other allergic symptoms associated with upper respiratory tract infections. Hyokof Flu Syrup Orange is suitable for use in adults and children above a specified age, with dosage adjusted accordingly. It should be used with caution in patients with hypertension, cardiovascular diseases, hyperthyroidism, or glaucoma due to the vasoconstrictive properties of Phenylephrine. Common side effects may include drowsiness, dry mouth, dizziness, or gastrointestinal discomfort. Contraindications include hypersensitivity to any component, concurrent use of monoamine oxidase inhibitors (MAOIs), and severe hypertension. Patients are advised to follow prescribed dosages and consult healthcare professionals before use, especially if pregnant, breastfeeding, or on other medications. This syrup offers effective symptomatic relief, improving patient comfort during acute cold and flu episodes.
