Clonidine (Clodin 150) 150mcg Tablets are used to manage high blood pressure (hypertension) and sometimes to treat withdrawal symptoms from opioids. Each tablet contains 150mcg of clonidine, an alpha-2 adrenergic agonist that works by reducing nerve signals to the blood vessels and the heart, helping to lower blood pressure. This medication is typically prescribed as part of a comprehensive treatment plan and comes in a bottle of 100 tablets.
