Retorlix 10 Tablet is used to treat high blood pressure and oedema (a build-up of fluid in the body). Hypertension or high blood pressure is a chronic condition in which the force exerted by the blood against the artery wall increases. Oedema may occur in case of high blood pressure, where fluids of the body get trapped in the tissues of the hands, arms, feet, ankles, and legs, leading to swelling.
