Does Viagra lose effectiveness over time?
If you notice that Viagra has lower effect on you there are a number of factors to take into consideration:
1) Viagra's absorption is hindered by fat in the stomach and intestines. If you take viagra after eating a fatty food, the Viagra may not be absorbed in adequate amounts to be effective.
2) There is a shelf life for Viagra. As the product ages, its potency is reduced.
3) Reduced effectiveness may be caused by some new health issues, thus it may be time for another checkup at your doctor’s.
What you can try is to stop taking Viagra and any other ED meds (herbal and otherwise) for a week. Then go back to the Viagra and see if it starts working well again.
