Will taking Atenolol regularly 12.5 mg/day cause low blood pressure?
Just be aware of the symptoms of low blood pressure and it would only be dangerous to take these 2 together if your blood pressure is considerably low already. 12.5 mg of atenolol is a low dose and if Viagra 25mg works for you I think you will be alright. Just let the other person aware and if you do happen to show signs of hypotension (low blood pressure), they can get assistance.
