DOSAGE IN RENAL FAILURE AND RENAL REPLACEMENT THERAPY
Dose as in normal renal function

Clonidine is a centrally acting alpha-2 agonist.

CONTRAINDICATIONS:

  • Hypersensitivity to clonidine.

  • Bradycardia


WARNINGS
Hypotension
Because severe hypotension may follow the administration of clonidine, it should be used with caution in all patients. It is not recommended in most patients with severe cardiovascular disease or in those who are otherwise haemodynamically unstable. The benefit of its administration in these patients should be carefully balanced against the potential risks resulting from hypotension.

PRECAUTIONS
General
Withdrawal of clonidine may lead to rebound hypertension. If this occurs, clonidine should be reinstituted and withdrawn more slowly.

Laboratory Tests:
No tests in addition to routine ICU tests are indicated

Drug/Laboratory Test Interactions:
None noted

If a patient receiving clonidine is also taking tricyclic antidepressants, the effect of clonidine may be reduced, thus necessitating an increase in dosage. Clonidine may enhance the CNS-depressive effects of alcohol, barbiturates or other sedatives.

Nervous system:
Excessive sedation, confusion, hallucinations
Cardiovascular system:
Hypotension, bradycardia, heart block
Dermatological
Rash, local skin reaction (transdermal)
Gastrointestinal:
Constipation
