How it works

Works on your heart... etc etc.
possibly the 'technical' reasoning in case that might be useful

Questions to Ask

What medications? add examples of ones that are relevant
- medical conditions?
- allergies?

How to take

self explanatory (dosing, time of the day, other important things to consider)

Side effects

list a few and maybe what to do if you experience them
- dizziness (let it know how it affects you before driving a car or anything else that requires high levels of concentration)

Other advice?

If related to the condition, get your blood pressure checked often etc. (maybe)
