===Contraindications===
 
Clonidine hydrochloride tablets should not be used in patients with known [[hypersensitivity]] to Clonidine.
 
===Warnings for Withdrawal===
 
Patients should be instructed not to discontinue therapy without consulting their physician. Sudden cessation of Clonidine treatment has, in some cases, resulted in symptoms such as [[nervousness]], [[agitation]], [[headache]], and [[tremor]] accompanied or followed by a rapid rise in blood pressure and elevated catecholamine concentrations in the plasma.
 
The likelihood of such reactions to discontinuation of Clonidine therapy appears to be greater after administration of higher doses or continuation of concomitant [[beta-blocker]] treatment and special caution is therefore advised in these situations. Rare instances of [[hypertensive encephalopathy]], [[cerebrovascular accident]]s and death have been reported after Clonidine withdrawal.
 
When discontinuing therapy with Clonidine hydrochloride, the physician should reduce the dose gradually over 2 to 4 days to avoid withdrawal symptomatology.
 
An excessive rise in blood pressure following discontinuation of Clonidine therapy can be reversed by administration of oral Clonidine hydrochloride or by intravenous [[phentolamine]]. If therapy is to be discontinued in patients receiving a [[beta-blocker]] and Clonidine concurrently, the beta-blocker should be withdrawn several days before the gradual discontinuation of Clonidine.
 
Because children commonly have gastrointestinal illnesses that lead to [[vomiting]], they may be particularly susceptible to hypertensive episodes resulting from abrupt inability to take medication.
