Rupex 10 mg Tablet, manufactured by Incepta Pharmaceuticals Ltd., contains Rupatadine Fumarate as its active ingredient. Rupatadine is a long-acting, non-sedative antihistamine that functions as a selective antagonist of histamine H1 receptors and also inhibits platelet-activating factor (PAF). This dual mechanism of action effectively reduces symptoms associated with allergic reactions. Rupex is indicated for the symptomatic treatment of seasonal and perennial allergic rhinitis and idiopathic urticaria. The recommended dosage for adults and adolescents over 12 years is 10 mg once daily, with or without food. It is important to consult a healthcare provider before use, especially for individuals with renal or hepatic insufficiency, as the use of Rupex is not recommended in these patients. Common side effects may include somnolence, headache, and fatigue. As with all medications, it is essential to follow the prescribed dosage and consult a healthcare professional for personalized advice.
