Spedra vs Stendra: What is the Difference and Which Is Available in the UK?

• Spedra and Stendra both contain the same active ingredient, avanafil, but Spedra is the only one licensed for sale in the UK.
• Stendra is the US market brand name for avanafil; it cannot legally be bought through a UK-regulated pharmacy.
• Both are generally available in the same three strengths, 50mg, 100mg and 200mg, since they share the same active ingredient.
• As a prescription-only medicine, genuine UK access to avanafil requires an appropriate clinical assessment and prescription, whether obtained online or in person.

Avanafil is the active ingredient in both Stendra and Spedra: Stendra is the US brand name, while in the UK the licensed brand is Spedra, and Stendra is not a UK-licensed product and is not supplied under that brand through UK-regulated pharmacies. For people in the UK looking into erectile dysfunction treatment, that distinction matters because the two names often cause confusion and can lead people toward unregulated sellers or risky import options.

This page explains what Spedra and Stendra actually are, why the same medicine has two brand names in different markets, how their UK and US licensing and availability differ, what dose strengths you may see, whether Stendra can legally be bought or imported into the UK, and how to access prescribed avanafil safely through proper UK prescribing routes.

Is Spedra the Same as Stendra?

Yes, in terms of active ingredients. Both Spedra and Stendra contain avanafil, a prescription treatment for erectile dysfunction in adult men and a phosphodiesterase type 5 (PDE5) inhibitor licensed for the treatment of erectile dysfunction in adult men. The difference between them is entirely about where they are licensed and marketed, not what they contain. Spedra is the brand name used in the UK, Stendra is the US brand for avanafil, which was approved by the FDA in April 2012.

Why Do Spedra and Stendra Have Different Names?

Pharmaceutical companies commonly market the same active ingredient under different brand names in different countries, often because different regional companies or licensing arrangements are responsible for bringing a medicine to market in each territory. This is a standard feature of how medicines reach different countries, not something specific to avanafil. The active ingredient name, avanafil, is the constant across every market; the brand name attached to it varies by where you are.

Each country's medicines regulator runs its own licensing process. In the UK, medicines are regulated by the MHRA, while in the US they are regulated by the FDA. A medicine can be approved in one country before another, or approved under different marketing arrangements in each, which is part of why the same active ingredient can end up with two different brand names rather than one global one. None of this affects what the medicine actually contains, only where and under what name it is legally sold.

Common Misconceptions About Spedra and Stendra

A few misunderstandings come up often enough to be worth addressing directly.

"Stendra is a newer or improved version of Spedra." This is not accurate. While avanafil may be described as a newer ED medicine compared with some older PDE5 inhibitors. Stendra and Spedra are the same active ingredient sold under different regional brand names at broadly the same time, neither is a later or upgraded formulation of the other.

"Stendra must be cheaper since it is the American version." Price comparisons across different countries' healthcare and pharmacy systems are not meaningful in this way, and more importantly, Stendra is not a legally purchasable option for a UK resident regardless of price.

"If a website will sell me Stendra and ship it to the UK, it must be a legitimate option." A website's willingness to sell and ship something is not evidence of legitimacy. Since Stendra has no UK-licensed product, a UK-regulated pharmacy would not ordinarily supply it under that brand.

"Bringing back a personal supply of Stendra from a trip abroad is fine because it is just for personal use." Personal importation of medicines is subject to UK rules, so bringing prescription medicines into the country should not be assumed to be automatically permitted simply because they are for personal use.

Is Stendra Available in the UK?

No. Stendra does not hold a UK marketing authorisation and is not a UK-licensed product supplied through UK-regulated pharmacies. Spedra is the UK-licensed avanafil product. If you are in the UK and looking to access avanafil, Spedra is the product actually available to you through a legitimate route.

Can You Buy Stendra in the UK?

Not through any properly regulated UK pharmacy. A UK-facing website offering Stendra directly should be treated with caution because Stendra is not a UK-licensed product. This is worth being cautious about specifically, since it is a common point of confusion for people who've come across the name Stendra online and assume it is simply an alternative product name to choose from, rather than a different country's licensing of the same ingredient. If a UK-facing site does list Stendra for sale, that alone is one of the clearer signs it is not a genuinely UK-regulated pharmacy, regardless of how professional the rest of the site looks.

What About Importing Stendra From Abroad?

Bringing a medicine that is not UK-licensed into the UK for personal use is governed by specific rules, not a straightforward personal choice.

A UK clinician may, where appropriate, prescribe an unlicensed medicine as a 'special' when the relevant requirements are met and there is a genuine clinical need.

Having prescription medicines posted from abroad or bringing in larger quantities may raise customs and regulatory issues, and the medicine may be detained or seized. Since Spedra already provides UK-licensed access to the same active ingredient, there is a clinical reason for a UK resident to pursue Stendra through an unregulated import route.

In practice, the "specials" route exists for medicines with no licensed UK equivalent at all, where a clinician has judged there is a genuine need that can not be met another way. Because Spedra already provides licensed UK access to avanafil, that clinical justification does not apply here; there's simply no gap to fill that Stendra would close and Spedra can not.

Travelling With Spedra

For travel, keep Spedra in its original packaging and carry evidence of your prescription; check the rules of your destination country before travelling. The reverse situation, someone visiting the UK who takes Stendra regularly, does not change UK law: Stendra still can not be purchased through a UK pharmacy while here. If ongoing treatment is needed during a stay, a UK prescriber can assess whether Spedra is appropriate and prescribe it where clinically suitable.

Spedra vs Stendra: Key Facts Compared

How Avanafil (Spedra/Stendra) Erectile Dysfunction Medications Work

Avanafil works by targeting PDE5, the enzyme that regulates blood flow to the penis, and helps preserve cGMP instead of letting phosphodiesterase type 5 (PDE5) break it down and cause blood vessels to constrict. During sexual stimulation, the nervous system triggers the release of nitric oxide, which activates an enzyme that produces cyclic guanosine monophosphate (cGMP). cGMP relaxes smooth muscle in penile blood vessels and erectile tissue, leading to increased blood flow that helps you get an erection. It works when you're physically aroused or physically stimulated because of physical stimulation, but it does not create arousal on its own. This mechanism is identical regardless of which brand name is on the packaging, since it is the same active ingredient. It is generally considered one of the faster-acting medicines in its class, with licensed UK dosing information describing use approximately 15 to 30 minutes before sexual activity.

A fuller breakdown of avanafil's mechanism, onset and duration is covered on our dedicated avanafil pages. This page focuses on the Spedra/Stendra naming and availability question rather than repeating that detail, and its absorption is less affected by food than with some other ED medications.

Dosage: Is Stendra the Same Strength as Spedra?

Generally, yes. Both are typically available in 50mg, 100mg and 200mg strengths, reflecting the same active ingredient at the same dose levels.

A lower dose may be chosen by a prescriber depending on your response and other factors. This is not a reason to treat the two as interchangeable for a UK resident, though, whatever the strength, the appropriate one is decided by a prescriber during a proper clinical assessment, not selected independently based on what's written on a particular brand's packaging.

If you have previously been told a specific strength while using Stendra elsewhere, that information can still be useful context to share during a UK consultation, but it does not replace a fresh assessment.

Your health, other medicines and individual response can all be reasons a prescriber recommends a different strength, even if a particular dose of Stendra was used before.

Avanafil is usually taken before sexual activity, and should not be taken more than once per day. It can be taken with or without food, although a high-fat meal may delay its onset.

Safety Considerations Whichever Name You See

Regardless of brand name, avanafil is broken down by an enzyme called CYP3A4, so drug interactions need to be checked carefully before looking at specific CYP3A4 examples. Potent CYP3A4 inhibitors make avanafil unsuitable altogether, and a smaller group of moderate CYP3A4 inhibitors mean a lower maximum dose and a longer gap between doses. Avanafil must never be combined with nitrate medicines, because the combination can lower blood pressure dangerously and increase the risk of low blood pressure. Interaction checks also need to cover alpha blockers, and some prescription medications and other medications can interact significantly as well. People with cardiovascular health conditions, heart disease, high blood pressure, low blood pressure, a previous heart attack, or chest pain should be assessed by a clinician, because physical activity itself may carry cardiac risk in those with pre-existing heart problems. These considerations do not change based on whether a product is labelled Spedra or Stendra, which is exactly why a full medicines review as part of a genuine consultation matters more than which brand name happens to appear on a box. Recreational drugs such as nitrate "poppers" and grapefruit juice should also be avoided because of interaction risk.

This also means that a product sourced outside a regulated route, whatever it is labelled, hasn't been through that medicines review at all. The safety information printed on official UK packaging and the patient information leaflet reflects the licensed UK product specifically; medicine obtained through an unverified channel carries no such assurance, even if the packaging looks similar to a genuine product.

Buying Spedra in the UK

Because avanafil is a prescription-only medicine. Because Spedra is a prescription-only medicine, it should only be supplied following an appropriate clinical assessment and valid prescription.

A legitimate online pharmacy should require an appropriate clinical assessment before dispensing Spedra.

Spedra Price in the UK

Prices are set by individual UK pharmacies and can change. On EveryDayMeds, Spedra is currently listed from £20.69, confirmed once a prescriber has reviewed your consultation rather than shown as a fixed public price. Cost shouldn't be the deciding factor in treatment; clinical suitability, decided through a proper assessment, comes first.

Signs of an Illegitimate Seller

Before buying avanafil online under any brand name, check that the pharmacy is registered with the General Pharmaceutical Council (GPhC) and displays a verifiable registration number. Be cautious of any site offering Stendra directly to UK customers, because Stendra is not a UK-licensed product. Check the provider's regulatory status before purchasing.

The same caution applies to sites offering avanafil with no prescription required, offering prescription-only medicine without an appropriate clinical assessment, using pressure tactics like countdown timers.
