Viagra (Sildenafil) Film-Coated Tablets

We stock original Viagra film-coated tablets containing sildenafil as sildenafil citrate, in three strengths - 25 mg, 50 mg and 100 mg - across pack quantities ranging from 10 tablets to 360 tablets, depending on strength. That range matters practically: a smaller pack can suit someone starting a prescribed strength, while a 90, 180 or 360-tablet pack may suit someone who already knows their working dose and wants fewer reorders. Because Viagra is normally taken on demand rather than as a daily tablet, the practical questions are which prescribed strength is suitable, how often it is likely to be used and how many tablets are sensible to keep on hand.

Strength is not simply a measure of how severe erectile dysfunction feels. Age, other medicines, kidney or liver function, cardiovascular health, side effects and previous response can all affect dose selection. A larger pack can reduce the need to reorder, but it is generally more sensible to establish that a particular strength is effective and tolerated before choosing a long-term quantity.

What Viagra is and where it fits

Viagra's active ingredient is sildenafil, supplied as sildenafil citrate. It is an oral, film-coated tablet and a phosphodiesterase type 5 (PDE5) inhibitor. Viagra is the original branded sildenafil formulation, with Pfizer Australia Pty Ltd as the Australian sponsor of registered Viagra sildenafil tablet products.

Sildenafil is established for treating erectile dysfunction in adult men. It does not increase sexual desire and cannot replace sexual stimulation; instead, it supports the physical erectile response when arousal occurs. It also does not treat the underlying cause of every erection problem. Erectile dysfunction can be associated with cardiovascular disease, diabetes, medicine effects, hormonal disorders, anxiety, depression or relationship factors, so a new or persistent change may warrant broader medical assessment rather than dose selection alone.

If you would like to consider the wider treatment context, you can browse our erectile dysfunction treatments. This guide focuses on the exact Viagra film-coated tablets and strengths described here.

Who might consider Viagra?

Sildenafil tablets are relevant to a fairly specific group of patients, and recognising the factors that apply to you can make the treatment discussion more useful.

• Adult men with erectile dysfunction of physical, psychological or mixed origin
• Men with diabetes-related erectile difficulty; use is established in this group, although response can be lower than in some other populations
• Men who prefer an on-demand tablet timed around sexual activity rather than a daily treatment
• Men whose prescriber considers a shorter-acting PDE5 inhibitor appropriate for their health and current medicines

Viagra is not indicated for women or anyone under 18, and it is not intended as a recreational or performance product for people without erectile dysfunction. Someone experiencing chest pain or breathlessness with modest activity, a recent major cardiovascular event or a significant change in exercise tolerance should seek medical advice before resuming sexual activity or using an erectile dysfunction medicine.

It is also worth considering what result you expect. Treatment may improve the ability to obtain and maintain an erection with stimulation, but it does not guarantee a response on every occasion. Anxiety, insufficient stimulation, poor timing, a heavy meal and excessive alcohol can all affect the experience without necessarily showing that sildenafil is unsuitable.

How does sildenafil work, and what does that mean in practice?

During sexual stimulation, nitric oxide contributes to the production of a signalling molecule called cyclic guanosine monophosphate, or cGMP, in penile tissue. cGMP relaxes smooth muscle and helps blood flow into the penis. PDE5 breaks down cGMP; sildenafil temporarily inhibits this enzyme, allowing the natural signal to have a stronger and more sustained effect.

In practice, the tablet does not cause an erection by itself. Arousal is still required, and taking a tablet without sexual stimulation may produce no noticeable erectile effect. Sildenafil also does not remain continuously active in the background like a medicine taken every day. Each dose is intended for a particular period, and the effect diminishes as the medicine is cleared.

This mechanism also explains some side effects and interactions. PDE5 inhibition can lower blood pressure modestly, while effects on related enzymes contribute to temporary changes in colour perception for some people. Medicines that strongly increase or compound these effects can make sildenafil unsuitable or require a lower dose under professional guidance.

Building a dosing routine that works for you

The generally recommended starting dose for most adult men is 50 mg, taken as needed about one hour before anticipated sexual activity. A prescriber may reduce the dose to 25 mg or increase it to a maximum of 100 mg according to effectiveness, tolerability, health factors and interacting medicines. No more than one dose should be taken in any 24-hour period.

• Take the prescribed tablet about 30 to 60 minutes before sexual activity for a practical starting routine
• Allow for sexual stimulation; the medicine does not trigger an erection automatically
• Swallow the film-coated tablet with water
• Avoid a heavy, high-fat meal close to the dose because it can slow absorption and delay onset
• Do not take more than one dose within 24 hours or add an extra tablet because the first response seems delayed
• Do not combine Viagra with another sildenafil product or any other PDE5 inhibitor

Food does not make sildenafil inherently unsafe, but a high-fat meal can make the timing less predictable. Alcohol can worsen erectile performance and add to dizziness or low blood pressure, particularly in larger amounts. Keeping the first few attempts relatively consistent in terms of meal timing, alcohol intake and the interval before sexual activity makes it easier to judge response.

A single disappointing attempt does not always establish treatment failure. However, any repeat trial should remain within the prescribed dose and frequency. Do not move between 25 mg, 50 mg and 100 mg or take multiple tablets to create a different dose without confirming that plan with a prescriber or pharmacist. People who are older, have severe kidney or liver impairment or use medicines that increase sildenafil exposure may need a lower starting dose.

Strengths and pack sizes we offer

We list Viagra as 25 mg, 50 mg and 100 mg film-coated tablets, priced in Australian dollars. Pack availability varies by strength: the 50 mg and 100 mg options include quantities from 10 tablets, while the 25 mg option starts at 20 tablets. Available quantities extend to 360 tablets.

• Smaller packs can suit an initial order when an appropriate strength has not yet been used for long
• Mid-size packs can suit someone who has established an effective, tolerated dose and wants more tablets on hand
• Larger packs can reduce reorder frequency for established use, provided the quantity is appropriate for the person's expected use

Choose the strength on clinical suitability rather than package value. Cutting or splitting a film-coated tablet should not be assumed to produce an accurate dose unless the particular tablet and the advice supplied with it support doing so. If the prescribed dose changes, confirm whether an existing pack remains appropriate rather than improvising with multiple tablets.

Quantity is a separate decision from strength. Consider likely frequency of use, the medicine's expiry date, storage conditions and whether treatment is still being reviewed. Ordering more tablets than can reasonably be used and stored correctly offers little practical benefit.

What should you expect, and when?

Many men notice an effect within 30 to 60 minutes of taking sildenafil, although onset varies. A heavy meal can delay it, while an empty stomach may make the timing more predictable. The useful response window is commonly around four hours, but this does not mean an erection lasts for four hours. It means the medicine may assist erections in response to stimulation during that period, with the effect gradually declining.

A successful response generally means improved ability to obtain and maintain an erection sufficient for sexual activity. It does not necessarily mean a stronger effect at a higher dose. Increasing the dose may increase adverse effects without producing a worthwhile improvement, which is why the aim is the lowest effective, well-tolerated dose.

If sildenafil repeatedly does not work despite correct timing, stimulation and use, a clinician can review adherence, the dose, contributing health conditions and whether another treatment is more suitable. Repeated failure should not be managed by exceeding 100 mg or taking doses closer together. Likewise, troublesome headache, flushing, indigestion, dizziness or visual symptoms may support reviewing the dose or considering an alternative.

What safety issues matter most before you start?

Who should avoid Viagra

Sildenafil must not be used by anyone with known hypersensitivity to sildenafil or another tablet ingredient. It must not be combined with nitrate medicines or nitric oxide donors in any form, including medicines used for angina, because the combination can cause a dangerous fall in blood pressure. It should also not be used with guanylate cyclase stimulators such as riociguat.

Sexual activity itself places additional demand on the heart. People for whom sexual activity is medically inadvisable because of their cardiovascular condition should not use erectile dysfunction treatment until assessed. A history of recent heart attack or stroke, severe hypotension, uncontrolled hypertension, unstable angina, serious heart disease or significant rhythm problems requires individual medical assessment rather than a general assumption that sildenafil is suitable.

People with severe liver or kidney impairment, bleeding disorders, active peptic ulceration, penile anatomical conditions or disorders that increase the risk of prolonged erections should also discuss their circumstances with a clinician. A hereditary retinal disorder or previous sudden vision loss, particularly non-arteritic anterior ischaemic optic neuropathy, calls for careful assessment and is not simply a routine dose-selection issue.

Common and less common side effects

• Headache and facial flushing
• Indigestion, nausea or nasal congestion
• Dizziness
• Visual disturbances, including blurred vision, increased light sensitivity or a temporary blue tinge to vision
• Muscle aches or back discomfort in some users
• Rarely, a prolonged or painful erection requiring urgent treatment

Seek urgent medical help for an erection lasting four hours or longer, sudden loss or marked reduction of vision, sudden hearing loss, chest pain, fainting, a severe allergic reaction or other serious symptoms. If chest pain occurs after sildenafil, do not take a nitrate medicine; tell emergency clinicians when the sildenafil dose was taken.

Because sildenafil can cause dizziness and visual changes, find out how you react before driving or operating machinery. Do not drive if affected. Side effects that are persistent, severe or difficult to distinguish from another medical problem should be reviewed rather than managed by repeatedly changing the dose yourself.

Interactions and precautions to check first

Sildenafil has several clinically important interaction groups, so check prescription medicines, non-prescription products and recreational substances before use.

Nitrate medicines are the clearest concern because combining them with sildenafil can cause a dangerous fall in blood pressure. The same prohibition applies to guanylate cyclase stimulators such as riociguat. This includes intermittent nitrate use, so simply separating the medicines by a short period is not a safe workaround without specific medical direction.

Alpha-blockers, sometimes prescribed for prostate symptoms or blood pressure, can add to the blood-pressure-lowering effect. A patient should generally be stable on alpha-blocker treatment before sildenafil is introduced, and a lower sildenafil starting dose may be considered. Other antihypertensive medicines can also contribute to dizziness or low blood pressure, even when the combination is not absolutely contraindicated.

Strong CYP3A4 inhibitors, including certain antifungal, antibiotic and antiviral medicines, can raise sildenafil levels and may require avoidance or a lower dose. Enzyme inducers can have the opposite effect. Sildenafil should not be combined with another PDE5 inhibitor, including tadalafil or vardenafil, or with another sildenafil-containing treatment. Grapefruit products may increase exposure in some circumstances, while heavy alcohol intake can worsen dizziness, low blood pressure and erectile function.

Provide a complete medicine list when asking for advice. This should include medicines used only occasionally, because an intermittent angina medicine or recreational nitrate can be just as important as a tablet taken every day.

Viagra, Levitra and Cialis: which timing profile suits you?

Once the safety picture is clear, the next practical decision may be between Viagra and another PDE5 inhibitor. These medicines share a therapeutic purpose, but individual response, side effects, food effects, onset and duration can differ. No option is automatically best for every person.

Levitra contains vardenafil and has a broadly similar on-demand role and duration to Viagra. The practical choice often depends on individual response, tolerability, medicine interactions and how reliably each treatment fits meal and activity timing. Someone who responds poorly to one PDE5 inhibitor may still respond to another, but the treatments should never be combined.

Cialis contains tadalafil and can have an effective window extending up to about 36 hours. That longer duration may allow more flexibility between dosing and sexual activity, while Viagra's shorter window may appeal to someone who prefers treatment to cover a more defined period. Tadalafil also has a daily dosing option for suitable patients, whereas the Viagra tablets described here are used on demand.

Duration alone should not decide the choice. Other health conditions, side effects, interacting medicines, previous response and how often treatment is expected to be used can be more important. Any switch should allow for the previous medicine to clear and should follow professional advice rather than overlapping doses.

Prescription status and access in Australia

In Australia, Viagra is a Schedule 4 prescription-only medicine and ordinarily requires a prescription from an authorised prescriber for lawful supply. Viagra used for erectile dysfunction is not subsidised through the Pharmaceutical Benefits Scheme, so the customer generally bears the full cost. These facts describe the medicine's classification and subsidy status in the Australian market.

Separately, our ordering policy does not require you to upload or submit a prescription document before we accept an order for this product. You can therefore place an order with us without a prescription document at checkout. That checkout process does not change Viagra's Schedule 4 classification in Australia, and it should not replace appropriate medical assessment of whether sildenafil is safe and suitable for you.

A medical review is particularly important for first-time erectile dysfunction, a sudden change in erectile function, cardiovascular symptoms, complex medicine use or repeated lack of response. Our pharmacist-supported team can help with product and medicine questions, but diagnosis and prescribing decisions remain matters for an authorised healthcare professional.

Ordering, delivery and receiving your pack

Ordering with us is straightforward, and our support team, including a pharmacist, is available 24/7 by email, online chat or phone if you have questions before or after ordering.

• Choose the advised strength - 25 mg, 50 mg or 100 mg - and an available pack quantity appropriate for your expected use
• Complete checkout in Australian dollars; our checkout does not require a prescription document for this product
• Contact our pharmacist-backed support team if you need clarification about the listed product, administration or important medicine interactions
• We pack the order discreetly and dispatch it for delivery to your address

Delivery timeframes are estimates and can vary with destination and operational conditions. Check the delivery address and postcode carefully before submitting the order, and contact our support team if you need current delivery expectations.

When the parcel arrives, confirm that the product name, strength and quantity match the order before use. Keep tablets in their original packaging, away from excess heat and moisture, and out of reach of children. Store Viagra at 25°C, with permitted temperature excursions between 15°C and 30°C. Do not use tablets that are damaged, appear altered or have passed their expiry date; contact our support team if the delivered pack raises a concern.

Making your decision

Choosing Viagra over another PDE5 inhibitor, and choosing among our available pack quantities, comes down to several separate decisions. First, sildenafil must be suitable alongside your health conditions and medicines. Second, the prescribed strength should provide a useful response with acceptable side effects. Third, Viagra's on-demand timing should fit your preference better than a longer-duration or daily alternative. Only then does pack quantity become the main commercial choice.

For a first or recently changed strength, a smaller available quantity may limit unnecessary surplus while response is assessed. For established use, a larger pack may reduce reorder frequency, provided the tablets can be used before expiry and stored correctly. With 25 mg, 50 mg and 100 mg film-coated tablets, quantities reaching 360 tablets and pharmacist-supported assistance available around the clock, we provide several ways to match the order to an established treatment plan without treating a larger strength or pack as automatically better.
