I am a 58 year old male with a history of erectile dysfunction. That is until the introduction of Viagra, which dramtaically improved my sex life. To reliably perform, I needed to take the 100 mg pill. I have had very few problems since I began using Viagra which was very soon after it was available. Now, it hardly works at all for me. I am not taking any new medications and have even lost weight since I began taking it. Normally, I would have symptoms such as a flushed face, stuffy nose and infrequently, heartburn. Now I get none of these symptoms and no real effect on my erections. This basically happened over a quick period of just a few weeks. Can something have caused this? Is this normal? What may have happened? What can I do to change this? This has become frustrating. Thanks.
100mg of Viagra is the highest recommended dose. If it isn't working, you may want to explore other causes of erectile dysfunction.
I would suggest some tests to make sure that there is not an anatomical or disease-related condition that is causing the dysfunction.
A testosterone level can be performed since a low level can affect sexual potency. An ultrasound can evaluate the blood vessels supplying the penis.
Nocturnal penile tumescence testing determines the quantity and quality of the erection. It can identify men with either arterial or venous dysfunction who may benefit from surgery.
If not already done, I would suggest a urology referral.
