Overview

Clonidine hydrochloride tablets are a prescription medicine used to treat hypertension. They may be used alone or with other blood pressure medicines.

This medicine acts in the brain to lower sympathetic outflow, which can reduce peripheral resistance, heart rate, and blood pressure. Blood pressure may begin to fall within 30 to 60 minutes after an oral dose, with the maximum decrease usually occurring within 2 to 4 hours.

Do not stop taking clonidine suddenly without consulting the prescriber. Abrupt discontinuation has been associated with nervousness, agitation, headache, tremor, and a rapid rise in blood pressure, and rare serious events have been reported after withdrawal.

Storage Information

Store at 20oto 25oC (68o to 77oF) [see USP Controlled Room Temperature].
