Final answer:
Clonidine (Catapres) can cause rebound hypertension when abruptly discontinued and taken with a beta-blocker.
Step-by-step explanation:
Clonidine (Catapres) is a medication that can cause rebound hypertension when abruptly discontinued and taken simultaneously with a beta-blocker. Rebound hypertension is the sudden increase in blood pressure that can occur when certain medications are stopped abruptly. This is because clonidine works by reducing blood pressure, so when it is stopped abruptly, there can be a rebound effect and blood pressure can rise.
