Whether you’re exploring ED treatment for the first time or comparing options like sublingual sildenafil, generic sildenafil, or Viagra, this guide explains everything you need to know — including how sildenafil works, how to buy sildenafil safely online, and what affects the sildenafil 20 mg tablet price.
What Is Sildenafil Medication?
Sildenafil medication is a prescription treatment for erectile dysfunction. It works by increasing blood flow to the penis during sexual stimulation, helping men achieve and maintain an erection firm enough for sexual activity.
Sildenafil is available as:
- Brand-name Viagra
- Generic sildenafil (same active ingredient, lower cost)
- Sublingual sildenafil (dissolves under the tongue for faster absorption)
Many patients choose generic sildenafil because it offers the same effectiveness at a more affordable price.
How Sildenafil Works (PDE5 Inhibitor Mechanism)
Sildenafil belongs to a class of medications called PDE5 inhibitors. These medications relax blood vessels and improve blood flow when a man is sexually stimulated.
How long does sildenafil take to work?
- Typically 30–60 minutes
- Some forms (like sublingual sildenafil) may work faster
- Effects can last 4–6 hours
Does sildenafil increase sexual desire?
No sildenafil helps with erections but does not increase libido.
