Viagra is somewhat pricey, but millions of men have been happy enough with its results to consider it a worthwhile investment. If you live in the United States, you won’t have any generic options available until the very end of 2017 at the earliest, and the drug won’t go fully off-patent until the year 2020.
That said, some doctors will help men who use the 50-mg dosage keep costs under control by prescribing 100-mg tablets (which usually cost the same as the 50-mg tablets) and advising patients to use a pill splitter to cut the tablets in half. Pill splitters are available at most pharmacies and big-box retailers for a few dollars.
