When looking for an erectile dysfunction (ED) medicine, men may tend to choose an option that offers the fastest results. The sooner the erection happens, the better, isn't it? The most common comparison for onset of action is between Sildenafil vs Tadalafil vs Avanafil tablets, as these are popular in the sexual wellness sphere. Viagra (Sildenafil), Cialis (Tadalafil), and Stendra (Avanafil) do ring a bell for anyone taking ED pills

So, let us understand which ED medication works fastest and how to choose between these alternatives.

What Are PDE5 Inhibitors?

Inhibitors of the enzyme phosphodiesterase-5 (PDE5) are often provided as treatment for aerectile dysfunction. They increase blood flow to the penile organ and relax its smooth muscles. The dilation of blood vessels helps the reproductive organ to keep blood in for longer and leads to a taut erection for several hours. However, the duration of how long an erection lasts after using an ED pill is one thing, while the fastest erectile dysfunction medication is a whole new experience in itself.

1. Sildenafil (Viagra)

When it comes to which ED medication works fastest, Sildenafil or Viagra takes 30 to 60 minutes. The peak effect is seen within an hour, and a hard-on capacity may last for 4 to 6 hours. The common dosage strength is 25mg, 50mg, 100mg, and so on. For best results, take the medicine on an empty stomach and avoid heavy meals.

Make sure you are sexually stimulated as well. The pros include dependable medication with wide recall among people and years of trust, considerably fast onset, and availability of generics at a lower cost. The cons are that some people may experience blurry or tinted vision and slow action of the medicine if taken immediately after food.

2. Tadalafil (Cialis)

The onset time for Tadalafil is 30 to 45 minutes. However, some can experience the effect as soon as 30 minutes. The peak effect is a couple of hours after the dosage and the erection duration is 24 to 36 hours. This is why Cialis is also known as the weekend pill. Dosing may start at 10mg, 20mg, and so forth. In some cases, a doctor may advise daily dosing as low as 2.5mg, 5mg, etc.

In terms of Sildenafil vs Tadalafil vs Avanafil, Cialis is not much impacted in efficacy when taken after food. The pros are evident, especially the longer time of erection ability and the facility of spontaneous erection during intimacy. Also, less food interaction is another benefit. The cons are a slower onset in contrast to Avanafil.

The clear winner for the fastest erectile dysfunction medication among the three discussed options is Avanafil. Its onset time is as little as 15 minutes. The peak work happens after 30 to 45 minutes of dosage, with an erection possibly lasting for 6 to 12 hours. You can take the medicine either after food or on an empty stomach. The standard doses are 50mg, 100mg, 200mg, etc.

The pros are a higher rate of satisfaction and successful intercourse because of the fast-acting effect, fewer medication interactions, and a lower chance of vision-related side effects. The cons may be a higher price due to better efficacy and faster action, and less widely available generics.
