What Causes Erectile Dysfunction Despite Taking Viagra?

Posted on Tue, 19 Sep 2017

Question: Hi! My partner has erectile dysfunction. Viagra used to work for him, but not anymore. When he can get a erection, he loses it, and he never has orgasm anymore. He is on Effexor for depression, but he was on this for years and the Viagra countered it okay for a few years. He is 63 years old, mildly overweight (15-20 lbs. I guess), and does not have hypertension. He is very sedentary however, and (may) have vitamin D deficiency, we don't know. He is a never-smoker. Also does not drink. Any suggestions?

No, he's not diabetic. He has been taking a steroid for a problem with his ear -- I think it's a fluid problem in the ear. The Viagra was 100 mg I think, at first he needed only one-half of it, then the whole pill, now it doesn't work at all. He used the Viagra about 2-3 times a month over a period of 6 years. We do know that he has a problem with dehydration, he had to go to the ER last year they said he was VERY dehydrated, he has been trying hard to drink more water. He occasionally gets dizzy and nauseated from dehydration. That's about all I can tell you.

Hello again

The serum electrolytes need to be checked , in terms of the dehydration you mentioned. If there is a lowered potassium level then it should be corrected as it causes severe muscular weakness as well as predisposing a patient to arrhythmias. A deranged sodium level should also be looked for and corrected accordingly.

Tadalafil is an alternative for sildenafil and can be advised on a trial basis instead to look for benefit regarding erectile dysfunction.

Wishing you best of health

Thanks
