There are four main types of erectile dysfunction pills that have been approved by the Food and Drug Administration (FDA) as treatments in the United States: sildenafil (Viagra), tadalafil (Cialis), vardenafil (Levitra) and avanafil (Sandra). In addition to Viagra, other medications for erectile dysfunction available in the United States include avanafil (Stendra), tadalafil (Cialis) and vardenafil (Levitra). All of them improve the blood supply to the penis. In combination with sexual stimulation, drugs can produce an erection sufficient to initiate and complete intercourse.
There is also a form of Levitra that dissolves quickly, called Staxyn, which is placed under the tongue. The most commonly prescribed medications for erectile dysfunction are sildenafil (Viagra) and tadalafil (Cialis). All erectile dysfunction pills are available by prescription only, so a person should first talk to a doctor or health professional to discuss symptoms. For example, people who have regular sex may prefer to take tadalafil, which is available as a daily pill.
Thanks to its name, horned goat weed stands out from other herbal supplements and pills marketed to increase sexual performance.
