I was on 30 mg and it was too much for me so I'm back to 20 mg. Inderal can lower blood pressure so they have to start you small, I think I started on 10 mg actually. My doctor didn't seem to want to up my dose past 30 mg even if it did agree with me. So is it a small dose? Honestly I guess it depends on the person and how much they can tolerate. Those with high blood pressure can tolerate more.
