ED Medications Online

Medically reviewed by Dr. Sarah Collins, MPharm, AHPRA Registered Pharmacist — Updated January 2026

Erectile dysfunction affects approximately 1 in 3 Australian men over 40 — and in the vast majority of cases is effectively treatable with medication. At RedstoneRX we offer all four approved classes of PDE5 inhibitors and their proven generics from GMP-certified manufacturers — at a fraction of Australian chemist prices. Viagra Generic (Sildenafil) from $0.99 AUD per pill, Cialis Generic (Tadalafil) from $1.10 AUD, Levitra Generic (Vardenafil) from $1.80 AUD — with discreet delivery to all Australian states and territories in 4 to 9 business days.

Our Most Popular ED Medications — Prices and Overview

Viagra vs Cialis vs Levitra vs Avana — Which ED Medication Is Right for You?

All four medications treat erectile dysfunction as PDE5 inhibitors — they work by the same mechanism but differ in onset speed, duration, and side effect profile. The right choice depends on your lifestyle, frequency of sexual activity, and individual response.

For first-time users — Viagra Generic (Sildenafil 50 mg) is the standard starting recommendation: best researched, lowest cost, most predictable. For maximum spontaneity over an entire weekend — Cialis Generic (Tadalafil) with its 36-hour duration. For fastest onset — Levitra Generic (Vardenafil) or Avana (Avanafil). For Australian men with diabetes — Vardenafil has the most extensive clinical evidence base specifically in diabetic and post-prostatectomy populations. For men with prostate issues (BPH) — Tadalafil is the only PDE5 inhibitor with a dual approval for ED and BPH.

How Do PDE5 Inhibitors Work?

All four ED medications work through the same fundamental mechanism — inhibition of the phosphodiesterase type 5 (PDE5) enzyme. During sexual arousal, nitric oxide (NO) is released in penile tissue, stimulating production of cyclic guanosine monophosphate (cGMP). cGMP relaxes the smooth muscle of penile blood vessels, allowing increased blood flow and producing an erection.

PDE5 is the enzyme that breaks down cGMP — shortening the erection window. Sildenafil, Tadalafil, Vardenafil, and Avanafil each inhibit PDE5, keeping cGMP levels elevated and enabling a sustained erection in response to sexual stimulation.

Critical: PDE5 inhibitors work only with sexual stimulation. Without arousal, no erection occurs regardless of the medication taken — they are not aphrodisiacs and do not increase sexual desire.

Price Comparison: Generic ED Medications vs. Australian Chemist Prices

For Australian men who take ED medication regularly, switching from brand-name medications at a local chemist to generics at RedstoneRX means savings of several hundred to several thousand Australian dollars per year — with identical therapeutic efficacy.

Why Generic ED Medications Work the Same as Brand

Generic medications contain the same active ingredient at the same dosage as the brand product. Bioequivalence is legally required — meaning identical absorption, identical peak blood concentration, and identical efficacy. The price difference exists solely because generic manufacturers do not bear the research and development costs of the original companies.

Viagra Generic with Sildenafil works identically to Pfizer's Viagra. Cialis Generic with Tadalafil works identically to Eli Lilly's Cialis. All generics at RedstoneRX are sourced from GMP-certified manufacturers including Ajanta Pharma, Centurion Laboratories, Cipla, and others — the same standard of manufacturing that supplies regulated markets globally.

Legal Status in Australia — Personal Importation Scheme

TGA Schedule status: Sildenafil, Tadalafil, Vardenafil, and Avanafil are Schedule 4 (prescription-only) medications in Australia under the Therapeutic Goods Act 1989. At Australian-registered pharmacies — both physical and TGA-approved online pharmacies — a valid prescription from an Australian doctor is required.

Personal importation from international online pharmacies: The TGA Personal Importation Scheme permits Australian residents to import up to a 3-month personal supply of most Schedule 4 medications for personal use from international sources without an Australian prescription. Purchasing ED generics from reputable international online pharmacies for personal use in quantities up to 3 months' supply is generally permitted under this scheme. Australian Border Force may inspect incoming parcels — personal-use quantities from reputable sources are rarely subject to enforcement action.

Our recommendation: Consult a doctor or pharmacist before taking any PDE5 inhibitor for the first time — particularly if you take heart medications, blood pressure drugs, nitrates, alpha-blockers, or any other regular medications. Australian men can access convenient online consultations through telehealth services such as Eucalyptus (Pilot), Kin Health, or InstantScripts.

Frequently Asked Questions — ED Medications in Australia

What is the best ED medication in Australia? There is no single best option — the right choice depends on individual needs. For first-time users: Viagra Generic (Sildenafil 50 mg) — best researched and most affordable starting point. For spontaneity: Cialis Generic (Tadalafil) — up to 36-hour duration. For fastest onset: Levitra Generic (Vardenafil) or Avana (Avanafil) — effective in 15–30 minutes. For men with diabetes: Vardenafil has the most extensive clinical evidence base in this population. For men with BPH: Tadalafil is the only ED medication with dual approval.

Is generic Viagra the same as Viagra in Australia? Therapeutically identical. Both contain Sildenafil Citrate at the same dosage. Generic manufacturers are legally required to demonstrate bioequivalence to the brand product — identical absorption, identical peak concentration, identical efficacy. The difference is the manufacturer, packaging, and price.

Can I buy ED medications online in Australia without a prescription? At Australian-registered pharmacies, a prescription is required. However, the TGA Personal Importation Scheme allows Australian residents to import up to a 3-month personal supply from international online pharmacies without an Australian prescription. Purchasing from reputable international sources for personal use is generally permitted under Australian law.

How much does generic Viagra cost in Australia? At Australian chemists, brand Viagra costs AU$15–30 per pill. Viagra Generic (Sildenafil) at RedstoneRX starts from $0.99 AUD per pill — up to 95% less. Many Australian men purchase 100 mg Sildenafil tablets and split them with a pill cutter, halving the cost per dose.

Which is better — Viagra or Cialis for Australian men? Neither is universally better. Viagra Generic (Sildenafil) is the most cost-effective and best-researched option for planned intimacy. Cialis Generic (Tadalafil) offers a 36-hour window and daily therapy option — ideal for spontaneity and men who value not having to plan timing precisely. Many Australian men try both via a trial pack before committing to one.

How long does delivery to Australia take? Standard delivery to all Australian states and territories takes 4 to 9 business days. Express shipping is available on request. All orders arrive in plain, unmarked packaging with a tracking number included.

Is Sildenafil the same as Viagra in Australia? Yes. Sildenafil Citrate is the active ingredient in Viagra. Viagra Generic contains the same Sildenafil Citrate at the same dosage as brand Viagra — with identical pharmacological action, onset, duration, and side effect profile. The difference is that Viagra is Pfizer's branded product while Sildenafil Generic is manufactured by GMP-certified international manufacturers at significantly lower cost.

Can I import ED medication into Australia? Yes. The TGA Personal Importation Scheme permits importation of up to a 3-month personal supply of Schedule 4 medications for personal use. This applies to ED medications including Sildenafil, Tadalafil, Vardenafil, and Avanafil ordered from reputable international pharmacies. Australian Border Force may inspect incoming parcels — enforcement against personal-use quantities is rare.

What is Levitra Generic and how does it differ from Viagra in Australia? Levitra Generic contains Vardenafil — a different PDE5 inhibitor to Sildenafil (Viagra). Key differences: Vardenafil has a faster onset (15–30 minutes vs 30–60 minutes for Sildenafil), is less affected by food, and has the most extensive clinical data in men with diabetes and post-prostatectomy ED. Both have similar duration (4–6 hours). Vardenafil costs slightly more than Sildenafil but offers advantages in specific clinical situations.
