FAQ

The active ingredient in these sublingual tablets is sildenafil, the same medicine ingredient used in sildenafil brand-name products for erectile dysfunction. This product is available in 50 mg and 100 mg strengths. A product name alone does not confirm the exact manufacturer, inactive ingredients, appearance or regulatory status of the product supplied.

A difference in colour, shape or packaging does not by itself show that the medicine is incorrect. Check the package label for sildenafil, the ordered strength, sublingual tablet dosage form, manufacturer, batch number and expiry date; compare any tablet imprint if one is present. Do not use the tablets if the ingredient, strength, dosage form, imprint, seal or physical condition appears wrong or compromised.

No. Sildenafil at these 50 mg and 100 mg erectile-dysfunction strengths should be avoided during pregnancy, as it is not intended for use in women and there is no established pregnancy use for this product. It should also be avoided while breastfeeding because there is no established role for this product during lactation.

Place the tablet under the tongue and allow it to dissolve; this product is for sublingual use rather than being used as a conventional swallowed tablet. Use only the strength and timing stated on the product label or supplied directions. Do not take more than the recommended amount, and do not combine sildenafil with nitrate medicines.

Description

We stock Viagra Professional as a sublingual sildenafil citrate tablet. Its defining practical feature is how it is taken: the tablet is placed under the tongue and allowed to dissolve rather than being swallowed whole like a standard oral sildenafil tablet. This may appeal if you find conventional tablets difficult or inconvenient to swallow. However, the sublingual format should not be treated as a guarantee of a faster, food-independent, or stronger response; product-specific timing can vary, and much of the established sildenafil evidence relates to conventional swallowed tablets.

What Viagra Professional actually is

Viagra Professional contains sildenafil, supplied as sildenafil citrate. Sildenafil is a phosphodiesterase type 5 (PDE5) inhibitor used to treat erectile dysfunction in adult men. We offer this product as sublingual tablets in 50 mg and 100 mg strengths. The route is sublingual, and each listed pill is one tablet at its labelled strength.

The active ingredient belongs to the same medicine class as conventional Viagra and other sildenafil products. The useful distinction is therefore the dosage form and method of administration, not a different active ingredient or a different intended condition. Anyone changing from another sildenafil product should still check the strength and directions rather than assume two formulations can be used interchangeably.

Who might consider Viagra Professional?

Sildenafil may be considered by adult men with erectile dysfunction when a doctor or pharmacist has determined that a PDE5 inhibitor is appropriate. Erectile dysfunction can have physical, psychological, medicine-related, or mixed causes, so a new or persistent problem can also justify assessment for contributing factors such as cardiovascular disease, diabetes, hormonal conditions, anxiety, or the effects of other medicines.

Practical decision factors include:

  • You prefer a tablet that dissolves under the tongue rather than one swallowed whole.
  • You are comparing the available 50 mg and 100 mg sildenafil strengths.
  • You understand that sexual stimulation is still required for sildenafil to work.
  • You have checked whether your heart health and current medicines make sexual activity and sildenafil suitable.
  • You are prepared to seek professional advice if erectile dysfunction is new, worsening, or accompanied by other symptoms.

This erectile-dysfunction product is not indicated for women or anyone under 18 years. It therefore has no intended role during pregnancy or breastfeeding. Known hypersensitivity to sildenafil or any ingredient in the particular tablet is also a reason not to use it.

How Viagra Professional works, and what that means day to day

During sexual stimulation, nitric oxide helps increase cyclic guanosine monophosphate, usually called cyclic GMP, in penile tissue. This relaxes smooth muscle and supports increased blood flow. PDE5 breaks down cyclic GMP; sildenafil inhibits that enzyme and helps preserve the natural erection response.

Sildenafil does not cause sexual desire and does not produce an automatic erection. If stimulation is absent, the medicine may appear to do little even when it has been absorbed. Stress, heavy alcohol consumption, relationship factors, underlying illness, and incorrect timing can also affect the response.

Viagra Professional is designed for sublingual administration. The exact onset and the effect of food on this particular formulation should be taken from its supplied directions rather than inferred from conventional tablets. For standard swallowed sildenafil, a high-fat meal can delay absorption, but that finding does not by itself prove that every sublingual formulation is unaffected by food.

How should you build a routine around dosing?

For conventional sildenafil used for erectile dysfunction, 50 mg is the usual starting dose for many adults. Depending on response, tolerability, other medicines, age, and liver or kidney function, a doctor may reduce the dose or increase it to a usual maximum of 100 mg. Viagra Professional is offered here only in 50 mg and 100 mg strengths, so anyone who has been advised to use a lower dose should not improvise by splitting a tablet unless the product instructions or a pharmacist confirm that this is appropriate.

  1. Place the tablet under your tongue and allow it to dissolve as directed; do not change the method of administration without professional advice.
  2. Follow the timing stated in the supplied product directions. Do not rely on a guaranteed 15-minute onset.
  3. Do not take more than one sildenafil dose in any 24-hour period.
  4. Do not increase the dose because the first attempt was unsuccessful. Timing, stimulation, alcohol, anxiety, and other factors may need to be considered first.
  5. Keep alcohol modest, as heavier drinking can worsen dizziness, reduce sexual performance, and add to blood-pressure-lowering effects.
  6. Never combine sildenafil with nitrate medicines or recreational nitrites such as amyl nitrite.

Store the tablets at 20°C to 25°C, with brief excursions permitted between 15°C and 30°C. Keep them dry, protected from light, in their original packaging, and out of reach of children.

Choosing between our available strengths and pack sizes

We list Viagra Professional in two strengths with the following current quantities:

  • 50 mg: 20, 30, 60, 90, 120, 180, 270, or 360 pills.
  • 100 mg: 10, 20, 30, 60, 90, 120, 180, 270, or 360 pills.

The count is the number of individual sublingual tablets in the pack, not the number of doses a person should take at one time. The smaller 10-pill option applies to 100 mg only. Current pricing and stock for each strength and quantity are shown in the pack options on this page.

Pack size is a supply decision, whereas strength is a clinical decision. A larger quantity does not make 100 mg more appropriate, and choosing 50 mg solely because it is lower does not account for interactions or medical contraindications. If you are new to sildenafil or unsure which strength is suitable, discuss dose selection with a doctor or pharmacist before use.

What should you expect, and how long can the effect last?

Established guidance for standard oral sildenafil commonly describes an onset within about 30 to 60 minutes and an effect window of up to around four hours, although response and timing vary. This does not mean an erection lasts for four hours; it means erections may be easier to achieve with sexual stimulation during part of that period.

The exact timing of Viagra Professional should be judged from the supplied directions and your individual response. The sublingual dosage form alone is not enough to promise that it will work within 15 to 30 minutes or last longer than a conventional sildenafil tablet. If the medicine does not work on an initial occasion, do not immediately repeat the dose. Incorrect use, insufficient stimulation, alcohol, anxiety, and an unsuitable dose can all contribute.

Sildenafil is used when needed rather than to create a permanent change in baseline erectile function. Seek professional advice if repeated correctly timed doses do not help, as another dose, treatment, or assessment may be more appropriate.

What safety issues deserve your attention first?

Common sildenafil adverse effects include headache, facial flushing, indigestion, nasal congestion, dizziness, and visual symptoms such as blurred vision or a temporary change in colour perception. Because dizziness and visual disturbance can affect driving or machinery use, wait until you know how you respond before undertaking either activity.

Sildenafil must not be used with nitrates, nitric-oxide donors, or the guanylate cyclase stimulator riociguat because the combination can cause a dangerous fall in blood pressure. It may also be unsuitable when sexual activity itself is inadvisable because of cardiovascular disease. A doctor should assess suitability after a recent heart attack or stroke, with severe heart disease, very low or uncontrolled blood pressure, significant liver or kidney impairment, certain inherited retinal disorders, or a previous episode of non-arteritic anterior ischaemic optic neuropathy.

  • Get urgent medical help for an erection that lasts more than four hours.
  • Stop taking sildenafil and seek urgent assessment for sudden loss or marked reduction of vision or hearing.
  • Seek emergency help for chest pain, fainting, severe breathlessness, or signs of a serious allergic reaction.
  • Tell emergency clinicians when sildenafil was taken. Do not use a nitrate for chest pain after taking it unless an emergency clinician specifically directs you.

People with conditions that increase the risk of priapism, including sickle cell disease, leukaemia, multiple myeloma, or certain penile abnormalities, need individual medical advice. Diabetes itself does not automatically rule out sildenafil, but cardiovascular health, kidney function, other medicines, and the cause of erectile dysfunction still matter.

Which interactions matter most before you take a dose?

A medicine review is important because several groups can alter sildenafil safety or exposure. Nitrates and riociguat are contraindicated. Alpha-blockers used for blood pressure or prostate symptoms can add to blood-pressure lowering, especially if treatment is not stable. Strong CYP3A4 inhibitors can increase sildenafil levels and may require a lower dose that this product does not offer. Other PDE5 inhibitors or erectile-dysfunction medicines should not be combined unless a specialist has expressly directed it.

Important medicine interactions for Viagra Professional

Relevant CYP3A4 inhibitors include medicines such as ritonavir, ketoconazole, itraconazole, clarithromycin, and erythromycin, although the size of the interaction varies. CYP3A4 inducers may reduce sildenafil exposure. Mention prescription medicines, over-the-counter products, supplements, and recreational substances when asking a doctor or pharmacist to check interactions. Grapefruit may also increase sildenafil exposure in some people, so avoiding large amounts around a dose is a sensible precaution.

Viagra Professional or Viagra: which fits your situation?

Both options use sildenafil for erectile dysfunction, but their administration formats differ. Viagra Professional is supplied here as a sublingual tablet, while conventional Viagra is a swallowed oral tablet. The practical choice may depend on how you prefer to take a medicine, which formulation is available to you, the strength advised, and how reliably you can follow its directions.

Key practical differences between sublingual and standard oral formulations.

A sublingual format may suit someone who dislikes swallowing whole tablets. A conventional oral tablet may suit someone who prefers a familiar formulation supported by extensive standard-tablet dosing information. Do not assume that the products have identical onset, food effects, bioavailability, or instructions merely because both contain sildenafil.

Prescription status and access in Australia

In Australia, sildenafil for erectile dysfunction is a prescription medicine. That regulatory classification describes how the medicine is scheduled in Australia and is separate from the documents our checkout asks customers to provide.

Under our ordering policy for Viagra Professional, you do not need to submit a prescription for us to accept an order. This does not make sildenafil a non-prescription medicine in Australia and does not replace an assessment by an Australian doctor or pharmacist. Professional advice is particularly important before first use, after a change in health or medicines, or when cardiovascular risk is uncertain.

PBS subsidy for Viagra Professional has not been confirmed. Any PBS eligibility should be checked for the specific sildenafil product, strength, indication, and applicable criteria rather than assumed from the active ingredient alone. Suspected adverse reactions can be reported to the Therapeutic Goods Administration through its established reporting channels.

Contact our support team if your pack, payment, tracking, or delivery needs attention.

Making your decision

Viagra Professional's central distinction is straightforward: it is our sublingual sildenafil tablet, offered in 50 mg and 100 mg strengths. The strongest reason to choose it over a conventional sildenafil tablet is a preference for under-the-tongue administration, not an assured faster onset or freedom from food effects.

Before selecting a pack, separate the main decisions. A doctor or pharmacist should help determine whether sildenafil and the chosen strength are suitable; the pack quantity then determines how many tablets you order. Check nitrates, riociguat, alpha-blockers, CYP3A4 inhibitors, other erectile-dysfunction medicines, cardiovascular health, and the urgent warning signs before use. If you would like to compare further treatment options, our Erectile Dysfunction range provides a useful place to continue browsing.
