Does effect of Viagra diminish with time ? I started using Viagra about 30 years of age, for first 10 years were nice, and working for me. I am 50 years now, about 6 to 7 years ago I started experecing that Viagra was not effective. then I tries, Levitra and Staxyn, they worked initially, now the effect started to diminish now.
any help will be appreciated, I am also looking to see doctor, may be penile injection is the option now.
My experience mirrors your own. But that is just anecdotal. Certainly some drugs become less effective for some individuals through continued use, just look at all the messages here dealing with the cancer treatment drugs. But the rate of diminishing effectiveness seems highly individualized; that's why doctors keep monitoring us. When a couple of drugs were losing effectiveness for me I stopped and/or substituted a different one; then sometime later tried the original and found it effective again. Drug fatigue? How our bodies react and accommodate to drugs, particularly with continuous use, is very complex to begin with, then you add on the effects of ageing. As long as you and your doctor agree the drug is safe I think it wise to experiment. Each of these PDE5 drugs works in slightly different ways. Injections worked fine for me, but was disruptive mood killer for us. YMMV.
