About SILDAMAX 100mg

SILDAMAX 100mg is a generic medication in our erectile dysfunction catalogue. Available in 4 pack sizes for bulk-pricing savings. Active ingredient: Sildenafil. Always read the patient information leaflet before use and consult a doctor or pharmacist if you have any underlying conditions or take other medications.

What makes SILDAMAX 100mg distinct

Sildamax 100mg is a sildenafil tablet in the familiar 100mg strength — another generic option for men who want a conventional swallowed pill at a low price.

Like all sildenafil it generally takes effect within around 30 to 60 minutes and lasts a few hours with arousal; a fatty meal can delay it. Read the leaflet and follow a doctor's advice, and never combine with nitrates.

Why choose SILDAMAX 100mg?

  • Contains Sildenafil — the same active ingredient used in the branded equivalent, manufactured under GMP conditions.
  • 4 pack sizes to choose from, with a lower per-unit price on the larger packs.
  • Plain, unbranded packaging — nothing on the outside indicates the contents.
  • Delivered Australia-wide, usually within 2–4 business days.

  • Do not exceed the dose described in the leaflet, and never take more than one medicine for the same purpose at the same time.
  • Buy from a reputable source and check the packaging and leaflet are intact on arrival.
  • Keep all medicines out of the sight and reach of children.

What is Sildamax 100mg and who typically chooses it?

Sildamax 100mg is a generic erectile dysfunction tablet containing 100mg of sildenafil citrate — the same active ingredient as Viagra and Fildena 100. Manufactured to a full-strength standard dose, it is the most economical sildenafil option in our range, starting at $53.91 for 20 pills. It is typically chosen by men who already know sildenafil works for them and want a dependable, low-cost supply rather than a branded name. Sildenafil helps blood flow into the penis when you are sexually aroused; it does not create desire on its own. If you have never used an ED medicine, speak to a doctor first — 100mg is the full dose, not automatically the right starting point for everyone. Our guide to ED causes and myths covers the basics.

How long does Sildamax 100mg take to work, and how long does it last?

Like all sildenafil products, what Sildamax 100mg does is respond to sexual stimulation — it does not produce an erection by itself at any point, only alongside arousal. A heavy, fatty meal is well documented to delay absorption of sildenafil generally, so many people find a lighter stomach more predictable, though your prescriber is the right person to advise on your specific timing. Take no more than one tablet in any 24-hour period and always read the patient leaflet supplied in the box. If duration is a priority, tadalafil-based medicines are known for a substantially longer window — see our health guides.

Sildamax 100mg vs Fildena — which sildenafil should you choose?

Sildamax 100mg and Fildena 100 contain the identical dose of the identical ingredient; the difference is manufacturer and price, with Sildamax the cheaper of the two. Choose Sildamax if per-pill cost is your priority; choose Fildena 100 if you prefer its well-known purple-triangle format. Fildena 120 steps up to 120mg — explicitly not a starting dose, and side effects such as headache and flushing become more likely as the dose rises. Super Fildena adds dapoxetine for men who also deal with premature ejaculation. If 100mg sildenafil already works well for you, there is no benefit in going higher — stay at the dose that works.

How do you get the best results from Sildamax 100mg?

Three things matter most. First, timing: take the tablet 30–60 minutes before sex and avoid a large fatty meal beforehand, which slows onset. Second, arousal: sildenafil only works alongside sexual stimulation — foreplay is part of the mechanism, not optional. Third, alcohol: one drink is generally fine, but heavy drinking blunts erections and worsens side effects. Never combine sildenafil with nitrate medicines (such as GTN sprays or isosorbide tablets) — the interaction can cause a dangerous drop in blood pressure. One tablet per 24 hours, maximum, and read the leaflet before first use. If it repeatedly underperforms, low testosterone or health issues may be involved — see the sleep-testosterone connection.

Why buy Sildamax 100mg from Kamagra AUS?

Counterfeit sildenafil is a genuine problem globally — how to identify a legitimate online pharmacy with wrong doses or no active ingredient at all. Every Sildamax box we ship is a sealed, GMP-manufactured product with the batch number and expiry date printed on the packaging, plus the original patient information leaflet inside. Orders arrive in plain, unbranded packaging across Australia within 2–4 business days, with free delivery on orders over $150 — which the 50-pill pack at $122.52 nearly reaches and the 100-pill pack at $228.70 comfortably clears. Before your first order, we verify details over WhatsApp so you know exactly who you are buying from.

What are the side effects of SILDAMAX 100mg?

Like all sildenafil tablets, SILDAMAX 100mg can cause side effects, though many men experience none at all. The most common are headache, facial flushing, nasal congestion, indigestion, dizziness and a temporary blue tint or increased brightness to vision. These are usually mild and pass within a few hours as the medicine wears off. Because 100mg is a full dose, side effects can be more noticeable than at lower strengths — sildenafil side effects generally scale with dose. Rare but serious reactions include sudden loss of vision or hearing, chest pain, and priapism — an erection lasting more than four hours. If any of these occur, stop using the tablet and seek medical help immediately, as untreated priapism can cause lasting damage.

Who should not take SILDAMAX 100mg?

SILDAMAX 100mg must never be taken with nitrate medicines (such as glyceryl trinitrate or isosorbide sprays and tablets) or recreational poppers (amyl nitrite) — the combination can cause a dangerous drop in blood pressure. Men taking alpha-blockers for prostate or blood-pressure problems should use extra caution and space doses apart. Avoid or seek medical advice first if you have significant heart disease, a recent heart attack or stroke, very low or uncontrolled blood pressure, severe liver or kidney impairment, or a rare inherited eye condition such as retinitis pigmentosa. It is also unsuitable for anyone allergic to sildenafil, and it is not intended for women or anyone under 18. When in doubt, check with a doctor or pharmacist before your first dose.

How should you store SILDAMAX 100mg and check it's genuine?

Store SILDAMAX 100mg in a cool, dry place below 25°C, away from direct sunlight and moisture — so not in a steamy bathroom cabinet. Keep the tablets in their original blister until the moment you take one, and always out of the sight and reach of children. To check your pack is genuine: each blister should be fully sealed with no loose or missing tablets, the foil should carry a printed batch number and expiry date matching the outer box, and the box itself should arrive intact with the manufacturer's leaflet inside. If anything looks tampered with, do not take the tablets — contact us and we will put it right.

Is SILDAMAX 100mg good value? Price per tablet explained

SILDAMAX 100mg is one of the most affordable full-strength sildenafil options we stock. At the smallest pack, 20 pills for $53.91 works out at roughly $2.70 per tablet. Scale up to 100 pills for $228.70 and the price drops to about $2.29 per tablet — a saving of around 15% per dose. The 100-pill pack also clears our free-delivery threshold of $150, so shipping costs nothing on top. If you are new to Sildamax, the 20-pack is a sensible, low-commitment starting point; regular users get the best per-tablet economics from the larger packs. Either way, you are paying a fraction of typical branded pharmacy prices for the same active ingredient.

About Sildenafil

General information about the active ingredient in SILDAMAX 100mg.

See the full Sildenafil guide & all Sildenafil products

What is Sildenafil?

Sildenafil is the active ingredient in a group of medicines used to treat erectile dysfunction in adult men. It belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors. It is the generic equivalent of the originally branded medicine Viagra. It is used to help men who have difficulty achieving or maintaining an erection sufficient for sexual activity.

How it works

Sildenafil works by blocking the PDE5 enzyme, which allows levels of a substance called cyclic guanosine monophosphate (cGMP) to rise in the tissues of the penis. This helps relax the blood vessels and improve blood flow when a man is sexually stimulated. Sexual arousal is still needed for the medicine to take effect; it does not cause an erection on its own. It generally begins to work within roughly half an hour to an hour and its effect usually lasts for a few hours.

How to take it

Sildenafil is normally taken by mouth a short time before planned sexual activity, at the dose advised by your doctor. It can be taken with or without food, although a heavy or high-fat meal may delay how quickly it starts to work. As a general rule no more than one dose should be taken in any 24-hour period. Always follow the instructions in the patient information leaflet and the advice of your doctor or pharmacist.

Side effects

Common (usually mild and temporary):

  • Headache
  • Flushing of the face
  • Indigestion or stomach upset
  • Nasal congestion (blocked or runny nose)
  • Dizziness
  • Changes in vision such as a blue tinge or blurring

Stop and seek medical help if you experience:

  • A painful erection lasting longer than 4 hours (priapism) — seek urgent medical help
  • Sudden loss or decrease in vision in one or both eyes
  • Sudden loss or reduction in hearing, sometimes with ringing in the ears
  • Chest pain during or after sexual activity
  • Signs of a serious allergic reaction such as swelling of the face, lips or throat, rash or difficulty breathing

Safety & who should not take it

  • Must NOT be taken with nitrate medicines (used for chest pain/angina) or nitric-oxide donors such as amyl nitrite 'poppers', as this can cause a dangerous drop in blood pressure.
  • Use with caution if you have heart or blood-vessel disease, or if sexual activity has been advised against for heart reasons.
  • Tell your doctor about any liver or kidney problems, as a dose adjustment may be needed.
  • Caution is needed if you have low blood pressure or take alpha-blockers or other blood-pressure-lowering medicines.
  • Drinking alcohol can lower blood pressure further and may reduce the medicine's effectiveness.
  • Grapefruit and grapefruit juice may affect how the medicine works and are best avoided.
  • Not intended for use by women, children or anyone under 18 years of age.

Storage

Store in the original packaging below 30°C, out of the sight and reach of children, and do not use after the expiry date.

Frequently asked questions

How long does sildenafil take to work?+

It typically begins to work within around 30 to 60 minutes of being taken, though this can vary between individuals and may be delayed by a heavy meal. Check the patient information leaflet for guidance.

Can I take it with food?+

It can be taken with or without food, but a large or high-fat meal may delay the onset of its effect. Your doctor or pharmacist can advise on timing.

How is sildenafil different from Viagra?+

Viagra is simply the original brand name under which sildenafil was first sold; a generic tablet delivers the same active substance at the same strength and works no differently.

Important: This information is general and not a substitute for medical advice. Always read the patient information leaflet supplied with your medicine and consult a doctor or pharmacist before use — especially if you have existing health conditions or take other medication.

Common questions about SILDAMAX 100mg

How much does SILDAMAX 100mg cost?+

SILDAMAX 100mg starts from $53.91. Several pack sizes are available — the larger the pack, the lower the per-unit price. Delivery is free on orders over $150, otherwise $12 standard (2–4 business days).

How is SILDAMAX 100mg delivered across Australia?+

Orders ship in plain, unbranded packaging from our Australian fulfilment centre, usually within one business day of payment clearing. Standard delivery takes 2–4 business days Australia-wide; express delivery is also available. All prices include GST, so there are no surprise bills on arrival.

What is the active ingredient in SILDAMAX 100mg?+

The active ingredient in SILDAMAX 100mg is Sildenafil — the same molecule used in the branded equivalent, manufactured under GMP conditions. Always read the patient information leaflet and consult a doctor or pharmacist before first use.

How do I pay for SILDAMAX 100mg?+

Choose your method at checkout: secure bank transfer, PayID, credit/debit card, or PayPal. You'll receive clear payment instructions by email, and we dispatch within one business day of payment clearing.

Is SILDAMAX 100mg discreetly packaged?+

Yes. Every order ships in plain, unbranded outer packaging — nothing on the outside indicates the contents or the pharmacy.

Is Sildamax 100mg the same as Viagra?+

It contains the same active ingredient — sildenafil citrate 100mg — at the same dose as the highest-strength Viagra tablet. The manufacturer, price, and appearance differ, but the pharmacology is the same: onset in 30–60 minutes and a 4–6 hour window, with arousal still required.

Why is Sildamax 100mg cheaper than Fildena 100?+

Both are generics from different manufacturers, and generic pricing varies by producer and volume. At $53.91 for 20 pills, Sildamax is the lowest-cost 100mg sildenafil in our range. Lower price does not mean lower dose — every sealed box carries batch and expiry details you can check.

Can I take Sildamax 100mg every day?+

Never take more than one tablet in 24 hours. Frequency beyond that is a question for your doctor, particularly if you have heart, blood pressure, or liver conditions. If you find yourself needing it very often, a medical review is more useful than more tablets — ED can signal underlying health issues.

Does Sildamax 100mg work without arousal?+

No. Sildenafil improves blood flow to the penis only when you are sexually stimulated — it does not cause spontaneous erections or increase desire. If low libido rather than erection quality is the problem, sildenafil is the wrong tool; discuss testosterone and other causes with a doctor.

Who should not take Sildamax 100mg?+

Anyone taking nitrate medicines for chest pain must not use sildenafil — the combination can dangerously lower blood pressure. Men with serious heart conditions, recent stroke, or severe liver problems should get medical clearance first. This is a prescription-only medicine, and that requirement exists precisely because it is not risk-free for everyone.

Can I take SILDAMAX 100mg with alcohol?+

A single small drink is unlikely to cause problems, but alcohol works against Sildamax in two ways: it can lower blood pressure further, increasing dizziness, and heavy drinking itself impairs erections. For the most reliable result, keep alcohol minimal or skip it on the nights you take a tablet.

What if SILDAMAX 100mg doesn't work the first time?+

Don't assume it has failed. Sildenafil often needs two to three attempts before the full effect shows, and it only works with sexual arousal. Take it on a lighter stomach, allow 30–60 minutes, and stay relaxed. Never take a second tablet within 24 hours; if several attempts fail, speak to a doctor.

Can I split a SILDAMAX 100mg tablet in half?+

Many men do split the tablet to take an effective 50mg starting dose, and the diamond shape breaks reasonably cleanly. The split will not be perfectly precise, so if you need exact dosing, ask a pharmacist. Store the unused half in the blister and use it soon after.

How long does SILDAMAX 100mg stay in your system?+

Sildenafil has a half-life of about four hours, so most of the effect fades after four to six hours, and the drug is essentially cleared within about 24 hours. This is also why the one-tablet-per-24-hours rule exists — earlier doses may still be partially active in your body.

Does SILDAMAX 100mg expire, and can I use old tablets?+

Yes — every blister carries a printed expiry date, typically two to three years from manufacture. Do not take tablets past that date: potency is no longer guaranteed. Stored correctly in the sealed blister, below 25°C and away from moisture, Sildamax stays fully effective right up to its expiry.
