Branded vs. Generic Sildenafil
When most people think of erectile dysfunction treatment, the first name that comes to mind is Viagra. Viagra was the original brand launched by Pfizer in the late 1990s, and it became so well known that the name is often used interchangeably with sildenafil.
However, Viagra is just one branded version of the drug. Since the original patent expired in 2013 in Europe, other pharmaceutical companies have been able to manufacture generic sildenafil. These generic tablets contain the exact same active ingredient (sildenafil citrate), in the same strengths (25mg, 50mg, 100mg), and are clinically proven to work in the same way.
The key differences are:
- Price – Generic sildenafil is usually much cheaper because multiple manufacturers can compete on cost. In the comparison above, the branded option is often several times more expensive than generics.
- Appearance – While Viagra comes as a well-known blue diamond-shaped tablet, generics may differ in colour, shape, or packaging depending on the manufacturer.
- Brand recognition – Some patients prefer Viagra simply because of its reputation and established history. Others are happy to switch to generic sildenafil for the savings.
Importantly, in the UK all generic sildenafil is strictly regulated by the Medicines and Healthcare products Regulatory Agency (MHRA). That means it has to meet the same standards for quality, safety, and effectiveness as Viagra. From a medical perspective, there is no difference in how the medicines work – only the brand name and the price tag.
For most people, generic sildenafil offers the best value, especially when bought from a UK-registered online pharmacy.
Prices change often, so it’s always worth checking the latest offers before placing an order. If you spot a better deal elsewhere or know a reputable pharmacy we should include in our next update, let us know at info@medino.com.
