Clonidine belongs to the group of medications called antihypertensives or vascular stabilizers. It is used alone or in combination with thiazide diuretics (e.g., hydrochlorothiazide) to treat high blood pressure. It is usually tried when other types of blood pressure medications are ineffective or cannot be used. This medication works by widening the blood vessels, which increases blood flow and lowers blood pressure. Clonidine can also be used to relieve menopausal hot flashes when hormone replacement therapy is not needed or not desired. For hot flashes, clonidine works by helping reduce the response of the blood vessels to stimuli that cause them to narrow and widen. This medication may be available under multiple brand names and/or in several different forms. PO administration: 0.1-0.3 mg q4-6hr; increase by 0.1 mg/day to 0.15-0.75 mg/day if required; do not exceed 2.4 mg/day TD administration: 100-200 mcg/day patch q7Days; initiate 0.1-0.3 mg PO q4-6hr for first 2 days to allow for adequate drug levels Not recommended as routine treatment for hypertension (Beers criteria) Potential for orthostatic hypotension and adverse CNS effects May cause bradycardia Immediate release: Lower initial doses than for nongeriatric adult dosing, as well as gradual adjustments, are recommended Extended release: May require lower initial dose than for nongeriatric adult dosing Skin reactions; patch (15-50%) Dry mouth (40%) Somnolence (19-38%) Headache (19-29%) Fatigue (13-24%) Drowsiness (33%) Dizziness (13-16%) Hypotension, epidural (45%) Postural hypotension, epidural (32%) Anxiety (11%) Epidural clonidine is not recommended for obstetric postpartum or perioperative pain management because the risk of hemodynamic instability (eg, hypotension, bradycardia) may be unacceptable in this population Dilute product with strength of 500 mcg/m L prior to use Epidural: Hemodynamically unstable patients (risk of severe hypotension) Do not discontinue suddenly (risk of rebound hypertension) Patch: May need to remove if severe erythema and/or localized vesicle formation develop at application site or generalized rash; consult physician Severe coronary insufficiency May cause xerostomia Recent MI Cerebrovascular disease Chronic renal failure Raynaud's disease Thromboangiitis obliterans History of depression (may exacerbate depression in cancer patients) May impair ability to perform hazardous tasks Remove patch before MRI (may cause burns) Hypotension may occur; usually responsive to IV fluids and, if necessary, appropriate parenterally administered pressor agents Cardiac conduction abnormalities: Sympatholytic action may worsen sinus node dysfunction and atrioventricular (AV) block, especially if coadministered with other sympatholytic drugs Titrate slowly and monitor vital signs frequently in patients at risk for hypotension, heart block, bradycardia, syncope, cardiovascular disease, vascular disease, cerebrovascular disease or chronic renal failure; measure heart rate and blood pressure prior to initiation of therapy, following dose increases, and periodically while on therapy; avoid concomitant use of drugs with additive effects unless clinically indicated; advise patients to avoid becoming dehydrated or overheated Epidural administration may result in mild respiratory depression (usually with higher than recommended dose) Use with caution in cerebrovascular disease Avoid as first line antihypertensive in the elderly due to high risk for adverse side effects Children may be particularly susceptible to hypertensive episodes when experiencing GI illnesses that lead to vomiting Discontinue oral immediate release formulations within 4 hr of surgery; restart as soon as possible following surgery Due to different pharmacokinetic profiles, oral formulations are not interchangeable with extended release on a mg-mg basis due to different pharmacokinetic profiles Central sympatholytic via stimulation of central alpha receptors; results in reduced sympathetic outflow, causing decreased PVR, HR, BP, and renal vascular resistance; produces presynaptic and postjunctional alpha-2 adrenoreceptor analgesia by preventing pain signal transmission to brain Postsynaptic alpha2-agonist stimulation may regulate subcortical activity in the prefrontal cortex, which may regulate the area of the brain responsible for attention, emotions, and behaviors, and thereby reduces hyperactivity, distractibility, and impulsiveness The above information is provided for general informational and educational purposes only.
