your doctor didn't answer the question, or you didn't ask? He/she must know you're on blood pressure medication. Although you can probably find the answer using Google, I'd ask the doctor's secretary to ask him/her about your specific case. As far as Viagra dosage, try to find out the lowest amount that 'works' it may be 25mg or even less. Cut up a 100 mg pill into 4 parts and start there. Good luck, it's a great drug.
