Viagra Extra Dosage is sildenafil at 120 mg, 130 mg, 150 mg and 200 mg — every one of them above the 100 mg maximum licensed single dose. That is the first thing to say about this page, because it is the thing the category name is designed to soften.
The licensed ceiling, and what sits above it
| Dose | Status | What the evidence supports |
|---|---|---|
| 25–100 mg | Licensed range | 100 mg is the approved maximum single dose worldwide |
| 120–150 mg | Above any licensed dose | No approved product information; adverse effects increase |
| 200 mg | Double the licensed maximum | No approved product information; visual side effects notably more common |
Sildenafil's dose-response curve flattens close to 100 mg. Past it, the things that keep rising are headache, flushing, indigestion, nasal congestion and — characteristically at the top of the range — visual disturbance: a blue tint, light sensitivity, blurring. Those effects come from the same mechanism that makes the drug work, so they scale with dose whether or not the benefit does.
We stock these strengths because men search for them, and we would rather they read something honest than something enthusiastic. If 100 mg is not working under good conditions, a bigger tablet is not the missing piece.
What to check before reaching for a bigger dose
- Timing. Thirty minutes is the floor, not the average — allow an hour.
- Food. A fatty meal delays sildenafil substantially. Many "failed" doses are simply doses taken after dinner.
- Alcohol. A couple of drinks is survivable; a heavy night is not, and no dose overcomes it.
- Arousal. Sildenafil enables a response, it does not initiate one. Anxiety is not outmuscled by milligrams.
- The molecule. Some men simply respond better to tadalafil. Switching is a more rational experiment than escalating.
If all of those are genuinely accounted for and a full 100 mg dose still does nothing, that is medical information rather than a shopping problem: persistent erectile dysfunction can be an early sign of cardiovascular or hormonal disease, and it is worth having looked at.
Where this sits in Australia
Sildenafil is Schedule 4 — prescription-only in Australia at every strength, and these high-dose presentations are not TGA-registered; they are made for other markets. If you have heart disease, take blood-pressure medication, take nitrates in any form, or have never used sildenafil, medical advice before starting is not optional at these doses.
If you are going to take it
One tablet, 30 to 60 minutes before sex, never more than one dose in 24 hours — a rule that matters more at these strengths, not less. Consider splitting: a 200 mg tablet halved is two licensed 100 mg doses, which keeps the price advantage that brought you here without the extra risk.
Side effects and the one absolute rule
Expect sildenafil's usual profile, more pronounced: headache, facial flushing, blocked nose, indigestion, and visual disturbance that becomes common rather than occasional at the top of this range. Dizziness on standing is more likely, especially with alcohol or blood-pressure medicines.
The absolute rule: never combine sildenafil with nitrates (angina medicines such as glyceryl trinitrate) or with amyl nitrite "poppers" — the combination can cause a catastrophic drop in blood pressure. Alpha-blockers, some antifungals and certain HIV medicines need medical input first; see ED pills and other medicines. An erection lasting more than four hours, or sudden loss of vision or hearing, is an emergency — priapism is a real risk of supra-therapeutic dosing and causes permanent damage if left untreated.
Where we would point you first
Generic Viagra at 50 mg or 100 mg is the licensed route and where most men should start. If the four-to-five-hour window is the real problem, tadalafil runs to about 36 hours — generic Cialis, or Cialis Daily to remove timing altogether. If speed of onset is the issue, the faster formats are Viagra Soft Tabs and Viagra Sublingual. Other high-strength products are grouped on strong-dose ED medications.
What the four strengths actually differ by
| Strength | Relative to the licensed maximum | Practical note |
|---|---|---|
| 120 mg | +20% | The smallest step above 100 mg; splits awkwardly |
| 130 mg | +30% | No clinical rationale for this increment over 120 mg |
| 150 mg | +50% | Halves cleanly into two 75 mg doses inside the licensed range |
| 200 mg | Double | Halves cleanly into two licensed 100 mg doses — the sensible way to buy it |
There is no pharmacological reason for the gaps between 120, 130 and 150 mg; they are packaging decisions, not dosing science. If price per milligram is what brought you here, the 200 mg tablet split in two is the most defensible way to use this page.
Storing it
Keep tablets in the blister, below 25 °C, away from bathroom steam. What expiry dates mean and how to dispose of what is left is covered in storing and disposing of medicines.
