    Comparing Sildenafil vs Viagra

    If you have heard of Viagra chances are you will have also heard of sildenafil. But, do you know why the two are linked? Well, they are actually the same thing. You will find out all you need to know about Viagra and sildenafil with UK Meds.

    What is the difference between Viagra and Sildenafil?

    The primary difference between Viagra and sildenafil lies in their branding and manufacturing. While both medications contain the same active ingredient, sildenafil, Viagra is the branded version produced by Pfizer, a pharmaceutical company. On the other hand, sildenafil is the generic version of the medication and can be manufactured by various pharmaceutical companies. 

    When did Pfizer's licence for Viagra expire?

    Pfizer's patent for Viagra expired in the UK in June 2013. This expiration allowed other pharmaceutical companies to produce generic versions of sildenafil, the active ingredient in Viagra, resulting in more affordable alternatives for consumers.

    What strengths do they both come in?

    At UK Meds we provide the same strengths of both branded Viagra and Generic sildenafil. The strengths of these tablets are 25mg, 50mg and 100mg. Other strengths may be available, however, these three are the most common and effective.  

    Does generic Viagra (sildenafil) look the same as Viagra?

    Generic Viagra (sildenafil) looks different to the recognisable shape and colour of Viagra. Viagra is diamond-shaped and blue. Generic sildenafil will look differently depending on its manufacturer, however, it is typically a circular white pill. The packaging and branding of the two medications will look different based on which manufacturer of generic sildenafil you get the medication from.

    Are the side effects of Viagra and sildenafil the same?

    Yes, in theory, the side effects of Viagra and sildenafil will be the same as they’re the same medication. Manufacturers of generic medications have to demonstrate bioequivalence, however, they typically inherit data and study results from the original branded product. This should mean that, if you switch from one medication to another, you should not notice any different effects. 

    Price difference: Why is sildenafil cheaper than Viagra?

    The price difference between Viagra and sildenafil is primarily down to branding and marketing strategies, as well as research and development costs. Viagra tends to be more expensive due to the significant investment in researching, developing, and testing the product, as well as obtaining patents. Once the patent expires, other pharmaceutical companies can produce generic versions of the medication at a lower cost as they haven't incurred the same research and development expenses. Brand-name medications also often involve investment in marketing, which further contributes to their higher price point. Some individuals may prefer to stick with the original brand for loyalty or perceived quality reasons, whereas others may choose the more affordable generic alternative, which provides the same effects.

    Viagra Dosages

    Are the dosages of Sildenafil and Viagra the same?

    Yes, the dosages of Sildenafil and Viagra are essentially the same. Both medications come in strengths of 25mg, 50mg, and 100mg. The varying dosages cater to a wider range of individual needs which allows for personalised treatment. The 25mg dosage is often suitable for men who may have experienced side effects on the higher dosages, providing a lower-strength option. The 50mg dosage is typically the starting point for most men, offering a balance between efficacy and tolerability. In cases where the 50mg dosage doesn't provide optimal results, 100mg may be prescribed for enhanced effectiveness.

    Are there any other branded forms of Viagra available?

    Yes, besides Pfizer, other pharmaceutical companies are producing and supplying generic forms of sildenafil. Pfizer themselves even produce a generic version of their own medication. Pharmaceutical companies may market or manufacture generic sildenafil under different brand names. Diversity in manufacturers and suppliers means that patients may come across different products when looking for generic Viagra. 

    What are alternative erectile dysfunction treatments to Viagra?

    There are several alternative treatments for erectile dysfunction (ED) aside from Viagra. These alternatives include:

    • Cialis (tadalafil): A popular ED medication that can be taken as needed, with effects lasting up to 36 hours.

    • Cialis Daily: A lower-dose form of tadalafil that is taken daily, allowing for more spontaneous sexual activity.

    • Viagra Connect: An over-the-counter version of Viagra available in the UK without a prescription.

    • Levitra (vardenafil): Another ED medication similar to Viagra, known for its effectiveness and lower likelihood of causing certain side effects.

    • Eropid: A brand of sildenafil, the same active ingredient as in Viagra, offering another generic option.

    • Spedra (avanafil): A fast-acting ED medication that can take effect in as little as 15 minutes.

    • Cialis Together: The over-the-counter version of Cialis (tadalafil).

    • Vitaros (alprostadil): A topical cream applied directly to the penis, offering an alternative for those who prefer not to take oral medications.
