I am caregiver for my grandma. Every time her heart races or she don't feel right she takes another heart pill. Her scrip is propranolal HCl er 80mg.

Do you go to her doctor appointments as her caregiver? If not, make an appointment for granny to see her heart doctor and take her. Explain your concerns to her doctor and you'll be told if this is how the medication is to be taken. If not, you'll learn proper dosing and care for her.
