Unhappy senior man close up

For years I took ED meds – Viagra, Cialis, and Levitra – with excellent results. Lately, they don’t work at all. Is this phenomenon typical, inevitable? If the answer is that the body adjusts itself out of the range of efficacy, does this adjustment also happen with medications taken for other purposes? I’m 63, and I’m curious in a scientific way. What can I do?


  • Michael Castleman says:

    It’s not inevitable for ED drugs to work less well or stop working over time, but it’s quite common. ED tends to become more severe with age. You say you’ve taken the drugs “for years,” so I infer you’re considerably older now than you were when you started on them, and your ED may have become more severe during that time. I suggest you discuss increasing your dosage with your prescribing physician. That often helps … but it also may increase your risk of side effects.

    Your question did not mention your lifestyle. Diet, exercise, sleep, and other lifestyle factors have major impact on erection function. For more, read the chapter on ED in my recent book, Sizzling Sex for Life.

    If upping your dose and lifestyle modifications don’t resolve things, then I suggest you consult a sexual medicine specialist. Visit the Sexual Medicine Society of North America.

    I wish you sizzling sex for life.
