A member asked:

Does clonidine 0.1 mg., as a blood pressure prescription, have the effect of slightly slowing the heart beat/rate? is it a beta blocker?

Clonidine is a centrally acting alpha-2 stimulator (what we call an agonist). It works on the feedback loop for adrenaline responsive nerves, and rather effectively. ~4% of people will experience bradycardia with it.

Yes, Clonidine can cause the heart rate to slow. It is an Alpha agonist, not a beta blocker.

Clonidine's central nervous system effects reduce the release of stress substances thereby lowering BP and mildly slowing ones heart rate. There a re two potential mechanisms for these effects, one of which is alpha2 receptor stimulation. It is not a beta blocker.

Clonidine is not a beta blocker. It belongs to a class of medications called alpha-2 receptor agonists that can be used to lower blood pressure. Clonidine may cause a person’s heart rate to slow down.
