April 15, 20266 min read

Viagra and sildenafil are often discussed as if they are completely different medicines. In fact, they share the same active ingredient, but differ in branding and price.

Key takeaways

  • Both use sildenafil citrate as the active ingredient.
  • Clinical effectiveness is comparable at equivalent doses.
  • Generic sildenafil is usually more affordable.
  • Choose licensed pharmacies to avoid counterfeit products.

Brand vs Generic

The branded product carries original marketing and packaging. Generics are approved alternatives that must meet the same quality and bioequivalence standards.

Price and Availability

In most UK settings, generic sildenafil offers better value. Pack size, dose, and provider model can still affect final cost per tablet.

How to Choose

For many patients, the best option is the one that is affordable, clinically suitable, and supplied through a legitimate service with proper medical checks.
