Summary

Fildena 100 delivers the standard 100mg sildenafil dose from an independent generic manufacturer. How it works and where it ships in Australia.

On this page

Sildenafil has been prescribed for erectile dysfunction since the late 1990s, and 100mg has long been treated as the standard reference dose in the class. Fildena 100 delivers that same 100mg sildenafil dose, produced by a manufacturer separate from other sildenafil brands in the Kamagra AUS catalogue.

The Same Active Ingredient, a Different Manufacturer

Fildena and Sildamax are both sildenafil-based generics, but they come from different manufacturers than Kamagra or Cenforce products. This is a normal feature of the generic medicines market: a single active ingredient can be legally produced by several manufacturers once patent exclusivity has lapsed, each selling under its own brand name at broadly comparable price points. The active ingredient, mechanism, and expected effect are the same across brands β€” what differs is the manufacturer, packaging, and sometimes tablet formulation, such as coating or shape.

How Sildenafil Works at This Dose

At 100mg, sildenafil relaxes smooth muscle in the blood vessels of the penis, allowing increased blood flow during sexual arousal. This is the dose most commonly referenced in clinical literature and is often where prescribers start patients who haven't previously tried a PDE5 inhibitor, though some begin lower depending on age, other medications, and cardiovascular history. Sexual stimulation is still required for the medicine to have any effect; it does not work on its own.

Onset and Duration

Sildenafil generally takes somewhere in the region of 30 to 60 minutes to take effect, and its effects are commonly understood to last for a number of hours, though this varies between individuals and can be affected by food intake β€” a heavy or fatty meal can delay onset. None of this differs based on which manufacturer produced the tablet; it's a property of sildenafil itself, so Fildena 100 behaves the same way in this respect as any other 100mg sildenafil product.

Deciding Between Doses

Fildena is also available at 120mg for men who need a higher dose, so 100mg is best thought of as the middle ground rather than the only option. Many men are prescribed 100mg as their first sildenafil dose and stay on it long-term without needing to change, while others move up or down after discussing their response with a prescriber over the following weeks or months.

Still Prescription-Only

Sildenafil, including Fildena 100, is a Schedule 4 Prescription Only Medicine under Australian law. It requires a valid prescription from a registered Australian prescriber, and no manufacturer or brand changes that requirement. This is worth repeating because generic pricing can sometimes create the impression that a product is less regulated β€” it isn't.

Side Effects and Precautions

As with any PDE5 inhibitor, Fildena 100 can cause side effects such as headache, flushing, nasal congestion, or mild visual disturbances in some men, and it should not be taken alongside nitrate medicines due to the risk of a significant drop in blood pressure. Men with heart conditions, uncontrolled blood pressure, or a history of stroke should have these discussed with a prescriber before starting treatment, and the patient information leaflet included with each pack should be read in full.

Where It Ships

Kamagra AUS dispatches Fildena 100 within one business day of payment, in plain unbranded packaging, with delivery typically taking two to four business days across the country. This reaches Tasmania's main centres β€” Hobart, Launceston, Devonport, Burnie, and Ulverstone β€” as well as inland New South Wales towns like Albury, Tamworth, and Orange, alongside every capital city from Sydney and Melbourne to Brisbane, Perth, Adelaide, Canberra, and Darwin. Orders over $150 AUD ship free, with bank transfer, PayID, credit or debit card, and PayPal all accepted, all in AUD.

Frequently asked questions

Is Fildena 100 the same as brand-name Viagra?+

It contains the same active ingredient, sildenafil, but is produced by a different manufacturer under its own brand name β€” a standard arrangement for generic medicines once patent protection has expired.

How long does 100mg sildenafil typically take to work?+

Generally around 30 to 60 minutes, though this varies between individuals and can be delayed by a heavy meal.

Do I need a new prescription for Fildena specifically?+

You need a valid prescription for sildenafil from a registered Australian prescriber. Your prescriber can advise on brand suitability as part of that prescription.
