Viagra vs Viagra Connect: What’s the Difference?

Published On : 15th August, 2025

At RX Direct, we often speak to patients who are unsure whether they should choose Viagra or Viagra Connect. Both are well-known options for treating erectile dysfunction in the UK, and both can be highly effective when used correctly. However, there are important differences in dosage, prescription requirements, and overall suitability that are worth understanding before making your choice. This guide will break down the similarities and differences so you can make an informed decision about which is right for you.

Understanding Both Products

Viagra is a prescription-only medicine containing sildenafil, used to treat erectile dysfunction by improving blood flow to the penis when a man is sexually stimulated. It has been available in the UK since the late 1990s and remains one of the most widely prescribed treatments for ED worldwide.

Viagra Connect is a pharmacy medicine version of sildenafil that was introduced in the UK in 2018. It is available without a prescription, meaning you can buy it after a consultation with a pharmacist, provided it is safe for you to use. It was launched to improve accessibility for men who may be reluctant to see their GP about ED.

Similarities Between Viagra and Viagra Connect

The most important similarity is that both contain the same active ingredient, sildenafil citrate. This means that when taken correctly, they work in the same way by helping blood vessels in the penis relax and allowing more blood to flow in during sexual arousal. The result is a firmer and longer-lasting erection that makes sexual activity easier and more satisfying.

Both medicines have a similar safety profile and are generally well tolerated. They work best when taken around 30 to 60 minutes before planned sexual activity and can remain effective for up to four hours. Sexual stimulation is still required for them to work.

Side effects for both are similar, including headaches, flushing, nasal congestion, and occasional dizziness or indigestion. These effects are usually mild and short-lived. In both cases, men with certain medical conditions or those taking nitrate medications for chest pain should not use sildenafil.

Key Differences in Strength and Prescription Rules

One of the main differences between Viagra and Viagra Connect is the available strength. Viagra is available in 25 mg, 50 mg, and 100 mg tablets. This allows for more flexibility in adjusting the dose to suit the patient’s needs and tolerance. Many men start with 50 mg, but their prescriber can adjust the dose up or down based on effectiveness and side effects.

Viagra Connect is only available in the 50 mg strength. While this dose works well for many men, it may not be enough for some, and without a prescription, there is no access to the higher 100 mg dose through this product.

The second major difference is how you obtain them. Viagra requires a prescription from a GP or an online doctor service after a full medical assessment. Viagra Connect, on the other hand, can be purchased directly from a pharmacy following a consultation with a pharmacist to confirm it is safe for you. This makes Viagra Connect easier to access for many men, but the reduced strength options and lack of ongoing medical review can limit its suitability in the long term.

Cost and Availability in the UK

Viagra is available as both the branded product and in generic form as sildenafil. The generic version is significantly more affordable and is often prescribed by the NHS, although NHS prescriptions for ED are only available to men who meet certain criteria. Many men choose to buy Viagra or generic sildenafil privately from registered online pharmacies.

Viagra Connect is available over the counter at most UK pharmacies and through regulated online providers. However, because it is a branded product and only comes in the 50 mg dose, it is usually more expensive than generic sildenafil. For men who use treatment regularly, this price difference can add up over time.

Who Might Choose Each Option

Viagra Connect may be a good choice for men who want quick and discreet access to ED treatment without booking a GP appointment. It can be particularly helpful for those trying ED medication for the first time and who are likely to respond well to the 50 mg dose.

Viagra, or generic sildenafil, is often the better choice for men who need more flexibility in dosing, require the 100 mg strength, or want a more cost-effective option for ongoing use. Because it is prescribed, there is the added benefit of regular medical reviews to ensure the medication is working safely and effectively.

RX Direct’s Guidance

While Viagra Connect has made it easier for men to access treatment, at RX Direct we generally recommend Viagra or generic sildenafil for long-term use. The ability to tailor the dose, choose from different strengths, and access more cost-effective generic options makes it a more versatile and affordable choice for most patients.

If you are starting treatment for the first time, Viagra Connect can be a useful entry point, but if the 50 mg dose is not effective enough or you want to reduce ongoing costs, it is worth speaking to a prescriber about switching to a prescription option. Book an online appointment today to get started. This also allows for a more detailed health assessment and ongoing support, which can improve results and ensure your treatment is as safe as possible.

Ultimately, both Viagra and Viagra Connect are effective treatments for erectile dysfunction when used correctly. The right choice depends on your personal needs, health background, and preferences.

At RX Direct, we can guide you through the options, ensure you receive genuine medication from a licensed UK source, and help you get the most out of your treatment.
