| ==Drug Interactions==
| |
| Clonidine may potentiate the CNS-depressive effects of alcohol, barbiturates or other sedating drugs. If a patient receiving clonidine hydrochloride is also taking tricyclic antidepressants, the hypotensive effect of clonidine may be reduced, necessitating an increase in the clonidine dose. If a patient receiving clonidine is also taking neuroleptics, orthostatic regulation disturbances (e.g., orthostatic hypotension, dizziness, fatigue) may be induced or exacerbated.

| | |
| Monitor heart rate in patients receiving clonidine concomitantly with agents known to affect sinus node function or AV nodal conduction, e.g., digitalis, calcium channel blockers and beta-blockers. Sinus bradycardia resulting in hospitalization and pacemaker insertion has been reported in association with the use of clonidine concomitantly with diltiazem or verapamil.

| Amitriptyline in combination with clonidine enhances the manifestation of corneal lesions in rats (see Toxicology).

| Based on observations in patients in a state of alcoholic delirium it has been suggested that high intravenous doses of clonidine may increase the arrhythmogenic potential (QT-prolongation, ventricular fibrillation) of high intravenous doses of haloperidol. Causal relationship and relevance for clonidine oral tablets have not been established.<ref name="dailymed.nlm.nih.gov">{{Cite web | last = | first = | title = CATAPRES (CLONIDINE HYDROCHLORIDE) TABLET [BOEHRINGER INGELHEIM PHARMACEUTICALS INC.] | url = http://dailymed.nlm.nih.gov/dailymed/lookup.cfm?setid=d7f569dc-6bed-42dc-9bec-940a9e6b090d | publisher = | date = | accessdate = 5 February 2014 }}</ref>
