I have have been using atenolol (with Tenoblock, Tenoprin or other names) since the eighties. First I was using 50 mg for many years. Later, especially during AF, my daily dose
has been the maximum
, 100 mg. Some doctors have suggested to use the high dose, and when needed, I was allowed to increase it a bit over 100. I have the feeling that I should not use so high doses, they will decrease my blood pressure and heart rate too much. Recently, I have dropped the dose to 75 mg.
