I am 71 years old and on high blood pressure medication. I have been on it for a number of years now. Back in the 1990's, I was using viagra when it was $10 a pill. Well as we all know times have changed and it's far way too expensive for me to use at $30 a pill. I am looking for an alternative. Something that would be safe to use, and less costly. I've noticed sildenafil as a possible alternative. Before I ask my doctor about it, I would appreciate your input on what might be best to use?
