A 47-year-old man with coronary artery disease, diabetes mellitus, and hypertension is currently taking clonidine. He is found to have a blood pressure of 170/90 mmHg after forgetting to take his medication for 48 hours.

What is the best strategy to control his blood pressure?

A. Restart clonidine
B. Start nitroprusside
C. Start esmolol
D. Add thiazide diuretic

Correct Answer is A

Comment:

Restart clonidine. Rebound hypertension is a known complication of clonidine. Immediate treatment of clonidine withdrawal involves reinstitution of therapy with a slow taper. The mechanism of action is thought to be an increase in sympathetic nervous system activity.
