What Is the Cheapest Generic ED Drug Right Now?

With an average price of $19.53 per recommended starting dose, sildenafil citrate, the generic equivalent of Viagra, is the least expensive generic erectile dysfunction drug available. 

The advent of generic competition in the erectile dysfunction drug market has put relief for the symptoms of male impotence within the financial reach of more men than ever before.

Of the five brand-name ED medications — Viagra, Levitra, Cialis, Staxyn, and Stendra — available in the United States, generic equivalents are now being marketed for all but one of them. The sole exception is Stendra, which wasn’t introduced until 2012.

Price is only one criterion for selecting the ED drug that’s best for you, and it’s certainly not always the most important one. It’s more important by far to select the drug that produces the best results for sex with the fewest, if any, side effects.

Price Still Matters

However, it would be foolish to dismiss the importance of price in choosing which ED drug to buy. For some men, all of these drugs may work equally well, in which case price may very well be the sole determinant.

The recommended starting dose (RSD) for each of the generic ED drugs varies from one medication to the other. For sildenafil citrate (generic Viagra), the RSD is 50 milligrams, while for vardenafil hydrochloride (Levitra and Staxyn) and tadalafil (Cialis), the RSD is 10 milligrams.

How to Maximize Savings

To maximize savings, it’s best to buy higher strength tablets, which cost the same as lower-strength pills. The higher-strength pills can then be split in two (or even four) to yield appropriate-size doses at the lowest price possible.

We’ve based our price calculations on the purchase of 100-milligram tablets of sildenafil citrate and 20-milligram tablets of vardenafil hydrochloride and tadalafil. Split in half, the 100-milligram tablets of sildenafil yield two 50-milligram doses of the drug, which is the RSD. If you’re lucky enough to get the desired results with an even lower dose, you can convert that 100-milligram tablet into four 25-milligram doses.

Similar savings are achieved by following the same strategy with the higher-strength tablets of vardenafil and tadalafil.

SILDENAFIL (100MG)$390.68$19.53
VARDENAFIL (20MG)$457.84$22.89
TADALAFIL (20MG)$502.86$25.14

Sildenafil Is Currently the Cheapest

Based on a recent price check at CVS, Walgreens, and Walmart, as well as the online prices posted at, the least expensive generic ED drug as of early June 2019 was sildenafil citrate, the generic equivalent of Viagra. As you can see from the accompanying table, its average price was $19.53 per recommended starting dose of 50 milligrams.

Somewhat higher  is vardenafil hydrochloride, the generic equivalent of Levitra, which comes in at $22.89 per recommended starting dose. Higher still in price is tadalafil, the generic equivalent of Cialis on demand, which has an average price of $25.14 per recommended starting dose.

Staxyn’s Generic is the Most Expensive

Not included on the table is vardenafil hydrochloride ODT, an orally disintegrating form of the medication and the generic equivalent of Staxyn. We could find a price listed for this form of the drug only at Because it is sold exclusively in packets of four 10-milligram tablets each, it is difficult to compare in a table with the other generic ED drugs.

The price per 10-milligram dose of orally disintegrating vardenafil is $37.77, making it far and away the most expensive of the generic ED drugs. However, for men who find it difficult or even impossible to swallow tablets, this method of delivery might make it the most preferable of all the generics.
