We stock Viagra Professional as a sublingual sildenafil citrate tablet designed to dissolve under the tongue rather than being swallowed like a standard film-coated tablet. That route of administration is the main product-specific distinction to weigh when comparing it with conventional sildenafil. Some people prefer a tablet that does not need to be swallowed whole with water, but the sublingual format should not be assumed to guarantee a faster effect or freedom from food-related variation unless the product-specific instructions establish those benefits. The practical decision is therefore about administration preference, available strengths, safety and how well sildenafil suits your circumstances.
Viagra Professional contains sildenafil citrate, providing sildenafil as the active ingredient. It is a phosphodiesterase type 5 (PDE5) inhibitor intended for erectile dysfunction in adult men and is supplied as a sublingual tablet. We offer 50 mg and 100 mg strengths, both of which are established adult sildenafil strengths for erectile dysfunction, although 100 mg is generally the usual maximum sildenafil dose rather than a routine starting choice.
Sildenafil supports the physical response needed for an erection when sexual stimulation is present. It does not create sexual desire, cause an automatic erection or address every possible cause of erectile difficulty. Persistent erectile dysfunction can sometimes be associated with cardiovascular disease, diabetes, hormonal problems, medicine effects or psychological factors, so a health assessment may be useful if symptoms are new, worsening or unexplained.
This product may be considered by an adult man seeking sildenafil for erectile dysfunction who prefers a tablet designed to dissolve under the tongue. The choice should not be based only on convenience or pack value: current medicines, cardiovascular health, previous response to sildenafil and the appropriateness of the available strengths all matter.
Extra care is appropriate if you have low blood pressure, significant heart disease, liver or kidney impairment, a bleeding disorder, an active stomach ulcer, penile deformity, a condition that predisposes you to priapism, or a history of serious sight problems. If you are uncertain, our pharmacist can help you identify questions to discuss before ordering or using the medicine.
During sexual stimulation, nitric oxide helps increase cyclic guanosine monophosphate, usually shortened to cyclic GMP, in penile tissue. Cyclic GMP relaxes smooth muscle and supports increased blood flow. PDE5 normally breaks cyclic GMP down; sildenafil inhibits this enzyme, allowing the natural signal to have a stronger and more sustained effect.
A sublingual tablet is designed to dissolve against the mucous membrane beneath the tongue. This differs from a conventional tablet that is swallowed whole and passes through the gastrointestinal tract. However, the extent and speed of absorption depend on the individual formulation. Evidence about the onset and food effect of standard swallowed sildenafil should not automatically be treated as proof of a particular onset for Viagra Professional. Follow the product-specific administration instructions and allow adequate time rather than taking an additional dose because an effect is not immediate.
Established guidance for conventional sildenafil commonly uses 50 mg as an initial adult dose, with adjustment according to response, tolerability and individual health factors; 100 mg is the usual maximum. Those principles provide useful context, but a non-standard sublingual formulation may have its own instructions. Do not increase the dose, combine tablets to create a different dose or repeat a dose without appropriate guidance.
Large amounts of alcohol can make it more difficult to achieve an erection and can add to dizziness or low blood pressure. A regular pattern of failed treatment should prompt a review of administration, stimulation, health factors and the chosen strength rather than repeated unsupervised dose changes.
We list Viagra Professional in 50 mg and 100 mg tablets, counted and sold as pills. The 50 mg strength is available in packs of 20, 30, 60, 90, 120, 180, 270 and 360 pills. The 100 mg strength is available in packs of 10, 20, 30, 60, 90, 120, 180, 270 and 360 pills.
A smaller pack may be more appropriate when you do not yet know whether the formulation suits you, while a larger pack can reduce how often an established user needs to reorder. Pack size should not determine dose: the strength still needs to be appropriate for your health, other medicines and previous sildenafil experience. If you would prefer to consider another sildenafil formulation, we also carry Kamagra.
Conventional swallowed sildenafil often begins to work in around 30 to 60 minutes and may support erectile response for a window of about four hours. This does not mean an erection should last for four hours; it describes the period during which an erection may be easier to achieve with stimulation. Individual timing varies with health, dose, response and other factors.
Viagra Professional has a different administration route, but a precise faster onset should not be promised without reliable formulation-specific evidence. Do not assume that placing sildenafil under the tongue eliminates every possible food effect or guarantees more predictable absorption. A heavy meal is known to delay the onset of standard swallowed sildenafil, while the clinical significance for this exact sublingual formulation has not been established for this exact sublingual formulation.
If sildenafil does not work on one occasion, possible explanations include insufficient time, lack of stimulation, anxiety, substantial alcohol intake, an unsuitable dose or an underlying health issue. Do not respond by taking another dose within 24 hours. Repeated lack of benefit is a reason to seek advice and consider whether a different formulation, dose or treatment approach would be more appropriate.
Sildenafil must not be used with nitrates in any form or with guanylate cyclase stimulators such as riociguat because the combination can cause a dangerous fall in blood pressure. It is also unsuitable when sexual activity has been advised against because of severe cardiovascular disease. Standard sildenafil product information includes important restrictions for people with severe hypotension, a recent stroke or heart attack, severe liver impairment, certain inherited retinal disorders or previous loss of vision associated with non-arteritic anterior ischaemic optic neuropathy. Individual assessment is important where any of these may apply.
Viagra Professional in these strengths is intended for adult men with erectile dysfunction. It is not indicated for people under 18 or for use by women, including during pregnancy or breastfeeding. This product-specific limitation does not mean sildenafil has no other medical uses under specialist care; separate sildenafil regimens may be prescribed for conditions such as pulmonary arterial hypertension.
Severe allergic reactions are uncommon but require emergency help. Stop using the medicine and seek urgent care for swelling of the face, lips, tongue or throat, difficulty breathing, or a widespread severe rash.
Nitrates and guanylate cyclase stimulators are contraindicated with sildenafil. Alpha-blockers used for high blood pressure or prostate symptoms can add to its blood-pressure-lowering effect, so a patient should generally be stable on the alpha-blocker and may need a lower sildenafil starting dose or carefully planned timing. Feeling faint, dizzy or light-headed after standing can be a sign of excessive blood pressure reduction.
Strong or moderate CYP3A4 inhibitors can increase sildenafil exposure. Examples include some azole antifungals, macrolide antibiotics and HIV treatments. Ritonavir can cause a particularly large interaction, and established guidance may require a much lower dose and longer interval than either strength offered on this page. Liver or kidney impairment can also increase exposure. These situations call for individual professional advice rather than simply selecting the 50 mg tablet.
Do not combine Viagra Professional with Viagra, another sildenafil medicine, tadalafil, vardenafil, avanafil or any other PDE5 inhibitor. Doubling up does not provide a safe way to improve the response and can increase adverse effects. Tell a pharmacist or prescriber about prescription medicines, non-prescription products and recreational substances before use.

These products all centre on sildenafil, so the meaningful distinction is the formulation and how it is taken rather than a fundamentally different mechanism. Product names such as "Professional" or "Soft" should not be interpreted as proof of superior effectiveness. Response depends on the dose delivered, formulation quality, individual health and correct use.
Viagra Soft is presented as a chewable option, whereas Viagra Professional is designed for sublingual use. Someone who dislikes swallowing conventional tablets may prefer either format, but chewing a tablet and holding one beneath the tongue are different administration methods. The comparison below focuses on that practical distinction and the available strength options.

Standard Viagra is a film-coated sildenafil tablet swallowed with water. Its administration, onset and food relationship are better established: a high-fat meal can delay absorption, and it is commonly taken around one hour before sexual activity. Viagra Professional may appeal to someone who prefers a sublingual tablet, but its route alone does not establish that it will act faster or work better than standard Viagra.
| Feature | Viagra Professional | Viagra |
|---|---|---|
| Active ingredient | Sildenafil | Sildenafil |
| Dosage form | Sublingual tablet | Film-coated tablet |
| How it is taken | Placed under tongue until fully dissolved | Swallowed whole with a glass of water |
| Available strengths | 50 mg, 100 mg | 25 mg, 50 mg, 100 mg |
| Medicine class | PDE5 inhibitor | PDE5 inhibitor |
If a swallowed tablet has worked reliably and is easy for you to take, there may be little practical reason to change. If swallowing is inconvenient, the sublingual format may be attractive, provided its available strength and safety profile suit you. A poor response to sildenafil itself may instead justify discussion of another PDE5 inhibitor or an assessment for underlying causes rather than only changing the tablet format.
Sildenafil products in the United Kingdom can have different supply classifications depending on the authorised presentation, strength, and conditions of sale. That legal context is separate from our own ordering requirement.
Our ordering requirement is a separate matter. We do not require you to submit a prescription for us to accept an order for Viagra Professional. That ordering policy does not determine the medicine's UK regulatory classification or replace an individual suitability assessment. Our pharmacist is available if you have questions about the strengths, contraindications or interactions before ordering. You can also browse our Erectile Dysfunction range when considering other relevant options.
We have supported customers online since 2018. Our support team is available 24/7 by email and online chat, and a pharmacist is available for medicine-related questions. Current prices and pack availability for the 50 mg and 100 mg options are displayed alongside this guide in GBP, allowing you to compare quantities before checkout without reproducing the offer grid here.
After you place an order, we prepare it for dispatch and provide the applicable delivery estimate during checkout. Check the selected strength, pill quantity and delivery address carefully before confirming payment. When the parcel arrives, confirm that the product and strength match the order and that the packaging is intact. Contact our support team before use if anything appears incorrect or damaged.
Viagra Professional is a sildenafil citrate sublingual tablet offered in 50 mg and 100 mg strengths. Its clearest distinction is that it is designed to dissolve under the tongue rather than be swallowed whole. That may suit a personal administration preference, but it should not be treated as a guarantee of faster action, stronger results or freedom from food-related variation.
Before choosing it, consider whether sildenafil is appropriate for your cardiovascular health and current medicines, whether 50 mg or 100 mg has been professionally identified as suitable, and whether the sublingual routine is genuinely preferable to a standard tablet. Then select from the available pack quantities according to realistic planned use rather than using pack value to drive the dose. Our pharmacist and 24/7 support team are available if you need help understanding the options or our ordering process.
I live in Reading. Can I check whether you deliver this medicine to my postcode before placing an order?
Yes. Enter your postcode at checkout to check whether delivery is available for your address before you complete the order.
I found what appears to be the same sildenafil product at another online shop for about half the price. Why should I order from you instead?
We stand behind the quality of the generic medicines we offer. We cannot verify what another seller supplies, how it is sourced or handled, or whether a similar name and lower price represent the same manufacturer, origin or product quality. The choice is yours, but it is worth deciding whether the saving is worth accepting that uncertainty.
I take ritonavir as part of my HIV treatment. Can I use sildenafil sublingual tablets for erectile difficulties?
Ritonavir can greatly increase sildenafil levels and raise the risk of side effects such as low blood pressure, fainting, headache and visual disturbances. Do not start sildenafil without a prescriber or HIV specialist reviewing the combination; any dose decision needs to account for your full treatment regimen and the sublingual formulation.

It cleared customs without any questions; that was the part I'd worried about, and I didn't need to do anything extra with the order for sildenafil.
A very good product.
Good value for money.
The pack of 30 suited what I needed. It was a practical size to choose for my partner.
This purchase has been consistently good quality. It was cheaper in the past, but still worth paying for.
Packed securely and neatly.
The sublingual tablets were a different colour from the pharmacy-bought brand, but had the same sildenafil.
