What erectile dysfunction pills are available?

In addition to Viagra, other ED drugs available in the United States include avanafil (Stendra), tadalafil (Cialis) and vardenafil (Levitra). These all improve blood supply to the penis. In combination with sexual stimulation, the drugs can produce an erection sufficient to initiate and complete intercourse. There is also a fast-dissolving form of Levitra, called Staxyn, that you put under your tongue.

One ED drug, Cialis, is FDA-approved for use daily in a dose of 2.5 or 5 milligrams. This helps to produce erections on demand and may also help relieve urinary problems, like difficulty starting urination, that result from an enlarged prostate.
