Avarante is a specific tadalafil-based product available in UK pharmacies, and it’s often compared with Viagra since both are used for erectile dysfunction but work over different timeframes. This guide explains what each actually is and how they differ, so you can make sense of the options in front of you rather than choosing based on name recognition alone.
Men researching ED treatment options often come across both Avarante and Viagra in pharmacies and online, sometimes without realising they contain different active ingredients entirely. Understanding what each actually is, rather than assuming they’re interchangeable versions of the same thing, helps you have a more informed conversation with a pharmacist or prescriber.
Avarante 10mg film-coated tablets contain tadalafil, a PDE5 inhibitor that works by relaxing blood vessels in the penis, supporting blood flow during sexual stimulation. In the UK, Avarante is classified as a Pharmacy (P) medicine, meaning it can be supplied following an assessment by a pharmacist, rather than always requiring a doctor’s prescription in the way some other tadalafil products do. It’s specifically a 10mg product; it isn’t available under this brand at other strengths such as 2.5mg, 5mg, or 20mg.
In the UK, medicines are broadly classified as prescription-only (POM), pharmacy medicines (P), or general sale. A Pharmacy medicine sits in between: it doesn’t require a doctor’s prescription, but it can only be sold under the supervision of a pharmacist, who assesses whether it’s appropriate for you based on your health and circumstances. This is different from simply picking a general sale product off a shelf, but it’s a quicker route than a full prescription in some cases.
Viagra is the original branded version of sildenafil, another PDE5 inhibitor that works in the same general way as tadalafil but over a shorter timeframe. According to the NHS, sildenafil is one of the main medicines used for erectile dysfunction in the UK. Sildenafil is also available as Viagra Connect, a Pharmacy (P) medicine version, alongside the fully prescription-only route.
When you’re assessed for a Pharmacy medicine like Avarante or Viagra Connect, a pharmacist will typically ask about your general health, current medicines, and whether you have any conditions that might make the medicine unsuitable, particularly heart problems or use of nitrate medicines. This is a genuine clinical check, not a formality, and the pharmacist can decline to supply it if they have concerns, referring you to a GP instead.
Both tadalafil and sildenafil share a broadly similar side effect profile, including headache, flushing, indigestion, and nasal congestion, since they work through the same mechanism. Neither is more or less likely to cause serious side effects such as priapism, an erection lasting longer than four hours, which is a medical emergency requiring urgent attention regardless of which medicine was taken.

Avarante is taken as a single 10mg tablet, at least 30 minutes before anticipated sexual activity, and can be taken with or without food. It should not be taken more than once a day, and it isn’t intended for continuous daily use. Men who anticipate needing tadalafil frequently, such as at least twice weekly, may want to discuss whether a once-daily lower-dose tadalafil regimen would suit them better, which is a separate product and regimen from Avarante specifically.
| Factor | Avarante (Tadalafil 10mg) | Viagra (Sildenafil) |
|---|---|---|
| Active ingredient | Tadalafil | Sildenafil |
| UK classification | Pharmacy (P) medicine | Available as a Pharmacy (P) medicine (Viagra Connect) or on prescription |
| Typical timing | At least 30 minutes before anticipated sexual activity | Approximately 1 hour before anticipated sexual activity |
| Duration | May remain effective for up to 36 hours | Shorter duration than tadalafil, generally around 4 to 5 hours |
Avarante can be taken with or without food, and tadalafil is generally less affected by a meal than sildenafil. A heavy or fatty meal can noticeably delay how quickly Viagra starts working, which is worth planning around if timing matters to you. Excessive alcohol can reduce how well either medicine works and increase the risk of side effects, so moderation is advisable with both.
If a pharmacist has concerns about your suitability for a Pharmacy medicine, or if your circumstances are more complex, such as multiple health conditions or several regular medicines, you may be referred toward a fuller prescription consultation instead. This isn’t a failure of the pharmacy route; it’s simply a recognition that some situations benefit from a more in-depth assessment.
Because Avarante contains tadalafil, it shares tadalafil’s long window of responsiveness, up to approximately 36 hours after a dose. This doesn’t mean a continuous erection for that entire window; sexual stimulation is still required throughout. Viagra’s shorter window means more precise planning around a specific occasion, which some men prefer for its predictability.
Because both medicines affect blood vessels throughout the body, not just in the penis, cardiovascular health is a central part of any assessment. This includes checking for recent heart attack or stroke, unstable angina, uncontrolled blood pressure, and certain heart failure conditions, any of which could make either medicine unsuitable or require a fuller medical review before treatment.
Yes, some men try one first and switch to the other if it isn’t giving the results they want, or simply to compare which fits their lifestyle better. Always disclose to whoever is assessing you that you’ve previously tried the other medicine, including any side effects or issues, since this is genuinely useful information for making the right choice.
There isn’t a single medically recognised “best” ED treatment for everyone. The NHS identifies sildenafil, tadalafil, vardenafil, and avanafil as the main PDE5 inhibitors used for ED, without ranking one as universally superior. The most appropriate choice depends on your medical history, other medicines, how you plan sexual activity, and your own tolerability and preferences.
Because Avarante is a Pharmacy (P) medicine rather than prescription-only in the way some tadalafil products are, it can be supplied following an assessment by a pharmacist. This still involves a professional judgement about your suitability, including checking for contraindications such as nitrate use, rather than being an unrestricted, no-questions-asked purchase.
Neither Avarante nor Viagra should be combined with nitrate medicines or nitric oxide donors such as amyl nitrite (“poppers”), due to the risk of a dangerous drop in blood pressure. Both are contraindicated in certain cardiovascular circumstances, including a recent heart attack, unstable angina, or uncontrolled blood pressure. Neither is intended for use by anyone under 18. Because ED can sometimes be a sign of an underlying condition such as heart disease, diabetes, or depression, a proper assessment of your general health is an important part of choosing either treatment.

If you tend to plan sexual activity around specific occasions and like a predictable window, Viagra’s shorter duration may feel easier to plan around. If you’d rather not time things tightly, or you’re sexually active more spontaneously, Avarante’s much longer window of responsiveness may suit you better. Neither preference is more valid than the other; it’s a genuine personal choice.
Both tadalafil and sildenafil can interact with certain other medicines, including alpha-blockers, some medicines used for high blood pressure, riociguat, and other PDE5 inhibitors. Always disclose your full medicine list, including over-the-counter products and supplements, when being assessed for either treatment, since some interactions aren’t obvious from the medicine’s name alone and a pharmacist needs the complete picture to assess this properly.
Our clinical team, supporting patients across the UK, considers your full health picture, including metabolic factors such as diabetes and cholesterol that can affect how well any ED treatment works, before discussing which option may suit you, whether that’s a Pharmacy medicine route or a fuller prescription consultation. If tablets aren’t your preference, we also offer Hezkue, an oral spray form of sildenafil.
No. Avarante contains tadalafil, while Viagra contains sildenafil. They’re different active ingredients that both belong to the same class of medicine, PDE5 inhibitors.
Avarante is a specific tadalafil 10mg branded product, classified as a Pharmacy medicine. Other tadalafil products, including different strengths and the daily low-dose regimen, are separate products that may have different supply routes.
No. Even as a Pharmacy medicine, Avarante requires a pharmacist to assess your suitability before it can be supplied, checking for contraindications and relevant health conditions.
Yes, Avarante’s tadalafil content means it may remain effective for up to 36 hours, considerably longer than sildenafil’s typical 4 to 5 hour window.
No, PDE5 inhibitors should not be combined with each other, as this increases the risk of side effects without any additional benefit.
