Clonidine Taper Schedule for 0.2mg Daily Dose
When discontinuing clonidine 0.2mg daily for hypertension, reduce the dose gradually over 2 to 4 days to prevent potentially life-threatening rebound hypertension, as mandated by the FDA label. 1
Critical Safety Warning
Abrupt discontinuation of clonidine can cause severe rebound hypertension with nervousness, agitation, headache, tremor, rapid blood pressure elevation, and elevated plasma catecholamines. 1 Rare cases have resulted in hypertensive encephalopathy, cerebrovascular accidents, and death. 1
Recommended Taper Protocol
For a patient on clonidine 0.2mg daily, use one of these FDA-approved approaches:
Option 1: 4-Day Taper (Preferred for Safety)
- Day 1-2: Reduce to 0.15mg daily 1
- Day 3-4: Reduce to 0.1mg daily 1
- Day 5-6: Reduce to 0.05mg daily 1
- Day 7: Discontinue 1
Option 2: 2-Day Taper (Minimum Duration)
Special Precautions During Taper
If the patient is concurrently taking a beta-blocker, withdraw the beta-blocker several days BEFORE beginning the clonidine taper. 1 The combination significantly increases the risk of severe rebound hypertension. 1
Monitor blood pressure closely during and for 48-72 hours after completing the taper. 1 Patients should be instructed to report symptoms of nervousness, agitation, headache, or tremor immediately. 1
Management of Rebound Hypertension
If excessive blood pressure elevation occurs during or after tapering:
- Restart oral clonidine immediately 1
- Alternatively, administer intravenous phentolamine 1
- Do not attempt to continue the taper until blood pressure is stable 1
Important Clinical Context
Clonidine is not a first-line agent for hypertension and is typically reserved for resistant hypertension after failure of ACE inhibitors/ARBs, calcium channel blockers, thiazide diuretics, and spironolactone. 2 The ACC/AHA guidelines do not list clonidine as a preferred agent for hypertensive emergencies. 2
Children are particularly susceptible to rebound hypertension if they develop vomiting or gastrointestinal illness that prevents them from taking clonidine. 1 This population requires especially careful monitoring during any taper. 1
Common Pitfall to Avoid
Never allow a patient to simply stop clonidine without a structured taper, even if switching to another antihypertensive. 1 The new medication should be started and titrated to effect while clonidine is still being taken, then clonidine should be tapered as described above. 1
