Levitra Generic

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

Is Generic Levitra the Same as Brand Levitra in Australia?

Levitra Generic contains the same active ingredient — Vardenafil — at the same dosage as Bayer's Levitra. Bioequivalence is legally required and verified by regulatory authorities: identical absorption, identical peak blood concentration, identical efficacy and side effect profile.

The price difference between brand Levitra and Levitra Generic exists solely because generic manufacturers do not bear Bayer's research and development costs. The therapeutic outcome — onset speed, duration, efficacy, and side effect profile — is identical.

Levitra Generic vs Viagra Generic vs Cialis Generic — Which Is Right for You?

Choose Levitra Generic (Vardenafil) if: you want the fastest onset among classic PDE5 inhibitors, you take your medication after a meal and found Sildenafil less predictable, you experienced visual blue tinge with Sildenafil, you have diabetes or have had prostate surgery, or you want an ED medication that has the most extensive clinical evidence base for these specific populations.

Choose Viagra Generic (Sildenafil) if: you are a first-time user wanting the most cost-effective starting point, or you prefer a well-established option for planned intimacy.

Choose Cialis Generic (Tadalafil) if: you want a 36-hour duration window, daily therapy, or you have both ED and BPH (enlarged prostate).

How Does Levitra Generic Work?

Vardenafil is a PDE5 inhibitor (phosphodiesterase type 5 inhibitor) — the same class as Sildenafil and Tadalafil. During sexual arousal, nitric oxide (NO) is released in penile tissue, stimulating production of cGMP (cyclic guanosine monophosphate). cGMP relaxes the smooth muscle of blood vessels in the corpus cavernosum, allowing the increased blood flow that produces and sustains an erection.

Vardenafil competitively binds to the active site of the PDE5 enzyme, preventing the breakdown of cGMP and keeping penile blood vessels relaxed during sexual stimulation. Vardenafil was first approved by the TGA for erectile dysfunction in 2004.

What makes Vardenafil clinically distinct from Sildenafil is its higher potency per milligram at the PDE5 receptor — meaning a lower dose of Vardenafil achieves comparable or superior enzyme inhibition. This contributes to its faster onset and the absence of the visual PDE6 cross-reactivity that causes the blue tinge seen with Sildenafil.

Critical: Levitra Generic works only with sexual stimulation. Without arousal, no erection occurs regardless of dose — it is not an aphrodisiac and does not increase sexual desire. It does not protect against sexually transmitted infections.

Vardenafil for Diabetes and Post-Prostatectomy ED — The Clinical Evidence

Levitra Generic (Vardenafil) has the most extensive clinical evidence base among PDE5 inhibitors specifically in the two Australian populations that find ED medication most challenging — men with diabetes and men who have undergone radical prostatectomy for prostate cancer.

Diabetes: ED affects approximately 50–75% of Australian men with diabetes — significantly higher than the general population. Diabetic ED is often more severe and less responsive to PDE5 inhibitors than non-diabetic ED because diabetes damages both vascular and neurological pathways involved in erection. Clinical trials specifically in diabetic populations have consistently shown Vardenafil to be effective: in one major randomised double-blind trial involving 452 men with type 1 and type 2 diabetes, Vardenafil 10 mg and 20 mg produced significant improvements in erectile function scores versus placebo, with 10 mg achieving 57% successful intercourse attempts versus 23% with placebo. Australian men with diabetes who have not responded adequately to Sildenafil or Tadalafil are frequently offered Vardenafil as the next therapeutic step.

Post-prostatectomy ED: Radical prostatectomy for prostate cancer — one of the most common cancer surgeries in Australian men — causes ED in 40–80% of patients due to cavernous nerve damage during surgery. Post-prostatectomy ED is particularly difficult to treat because the normal neurological trigger for erection (nitric oxide release) is impaired. Vardenafil has been studied specifically in post-prostatectomy patients and has shown clinically meaningful benefit even in men with significant nerve damage — particularly when used as early penile rehabilitation therapy following surgery.

Why Vardenafil Works After a Meal — and Sildenafil Does Not

One of the most practical advantages of Levitra Generic over Viagra Generic for Australian men is its resistance to the food effect. High-fat meals — a steak dinner, a restaurant meal, fish and chips — significantly delay Sildenafil absorption and can reduce its peak blood concentration by up to 29%, making the onset unpredictable.

Vardenafil absorption is minimally affected by most meals. While a very high-fat meal (>57% fat content) can modestly reduce Vardenafil's peak concentration, standard meals have little clinical impact. For Australian men who want to take their ED medication at dinner or after a social meal and expect reliable, fast onset — Vardenafil is consistently more predictable than Sildenafil.

No Visual Colour Disturbances — Vardenafil vs Sildenafil

Sildenafil (Viagra) is known to occasionally cause visual side effects — most notably a blue tinge or colour shift in vision, increased sensitivity to light, and blurred vision. These effects occur because Sildenafil has a degree of cross-reactivity with PDE6 — an enzyme involved in retinal photoreceptor function.

Vardenafil is significantly more selective for PDE5 over PDE6 than Sildenafil. As a result, visual colour disturbances are not a reported side effect of Vardenafil. For Australian men who have experienced blue tinge or visual disturbance with Sildenafil — or who have occupations or hobbies where colour discrimination is important (pilots, designers, photographers, drivers) — Vardenafil offers a clinically meaningful advantage.

Dosage Guide — Levitra Generic in Australia

Standard starting dose: 10 mg taken approximately 30 to 60 minutes before planned sexual activity. For many Australian men, onset begins in 15 to 30 minutes.

Dose adjustment:

• 5 mg — recommended for men over 65 years of age, or men with moderate hepatic impairment, or men taking certain medications that may increase Vardenafil blood levels (alpha-blockers, certain antibiotics or antifungals)
• 10 mg — standard starting dose for most Australian men
• 20 mg — maximum recommended dose if 10 mg is insufficient. Do not exceed 20 mg in 24 hours

With or without food: Levitra Generic can be taken with or without food. Unlike Sildenafil, moderate meals do not significantly affect onset. For fastest results, take on an empty stomach or after a light meal. A very high-fat meal may modestly slow absorption.

Maximum frequency: No more than once per 24 hours.

Men over 65: Start with 5 mg. Older men clear Vardenafil more slowly, resulting in higher blood concentrations at the same dose. 5 mg provides effective ED treatment in most men over 65 with a lower risk of side effects.

Men with diabetes: Standard dosing (10 mg) applies for most diabetic men. ED associated with diabetes often requires several attempts before optimal response — try at least 6 to 8 times before concluding the medication is not effective.

Price Comparison — Levitra Generic vs Australian Chemist

For Australian men who take Levitra regularly, purchasing Levitra Generic at RedstoneRX instead of brand Levitra at a local chemist means savings of up to AU$1,700 per year — with therapeutically identical results.

Legal Status in Australia — TGA Schedule 4 and Personal Importation

TGA Schedule status: Vardenafil (Levitra) is a Schedule 4 (prescription-only) medication under Australian law. At TGA-registered Australian pharmacies — physical and online — a valid prescription from a licensed Australian doctor is required. Brand Levitra has been TGA-registered in Australia since 2004.

TGA Personal Importation Scheme: 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 Levitra Generic 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 an Australian GP or urologist before taking Vardenafil for the first time — particularly if you take any heart medications, antiarrhythmics, blood pressure drugs, or alpha-blockers for prostate. Australian men can access same-day telehealth consultations for ED through Eucalyptus (Pilot), Kin Health, InstantScripts, or HotDoc.

Drug Interactions — What Australian Men Must Know Before Taking Vardenafil

Vardenafil interacts with several medication groups. Some interactions are shared with all PDE5 inhibitors — others are specific to Vardenafil. Always inform your Australian GP or pharmacist about all medications you take before starting Vardenafil.

Absolute contraindications — never combine:

• Nitrate medications (nitroglycerin/GTN spray, isosorbide dinitrate, isosorbide mononitrate) — used for angina and heart disease. The combination causes severe, potentially life-threatening hypotension. Absolute contraindication — there is no safe dose of Vardenafil for men taking nitrates.
• Poppers (amyl nitrite, butyl nitrite) — recreational drugs with nitrate action widely used in Australia. Same dangerous blood pressure drop as cardiac nitrates. This combination is potentially fatal.
• Class IA antiarrhythmics (quinidine, procainamide, disopyramide) — these medications prolong the QT interval. Vardenafil also prolongs the QT interval. The combination increases risk of dangerous cardiac arrhythmias. Absolute contraindication specific to Vardenafil — not shared to the same degree by Sildenafil or Tadalafil.
• Class III antiarrhythmics (amiodarone, sotalol, dronedarone) — same QT prolongation risk as Class IA. Absolute contraindication. This is Vardenafil's most important unique drug interaction — Australian men taking amiodarone or sotalol must not use Vardenafil.
• Riociguat (Adempas) — used for pulmonary hypertension. Severe hypotension risk. Absolute contraindication.
• Other PDE5 inhibitors (Sildenafil, Tadalafil, Avanafil) — never combine two ED medications simultaneously or within 24 hours.

Use with caution — inform your doctor:

• Alpha-blockers (tamsulosin/Flomax, doxazosin/Cardura) — commonly prescribed to Australian men for BPH or hypertension. The combination can cause significant blood pressure drop. Start Vardenafil at 5 mg under medical supervision if you take an alpha-blocker.
• Strong CYP3A4 inhibitors (ketoconazole, itraconazole, ritonavir, clarithromycin, erythromycin) — significantly increase Vardenafil blood levels. Dose reduction to 5 mg maximum is recommended with these medications.
• Antihypertensive medications — additive blood pressure lowering possible. Monitor blood pressure when starting Vardenafil.
• Alcohol — one to two standard Australian drinks are tolerable for most healthy men. Larger amounts increase blood pressure drop risk and can independently impair erection quality.
• Grapefruit juice — can increase Vardenafil blood levels. Best avoided on the day of use.

Side Effects of Levitra Generic (Vardenafil)

Common side effects (affect 1 in 10 users):

• Headaches
• Facial flushing
• Nasal congestion — stuffy or runny nose (particularly characteristic of Vardenafil)
• Indigestion
• Dizziness

Vardenafil does NOT cause: visual colour disturbances or blue tinge — a common Sildenafil side effect that is not reported with Vardenafil due to its greater PDE5 selectivity.

Rare but serious side effects — seek immediate attention at your nearest Australian emergency department:

• Priapism — painful erection lasting more than 4 hours. Requires immediate hospital treatment. Call 000 or go to your nearest emergency department immediately.
• Sudden vision loss — stop Vardenafil immediately and seek urgent medical attention.
• Sudden hearing loss or tinnitus — stop immediately and seek medical attention.
• Chest pain or cardiac symptoms during or after sexual activity — stop immediately and call 000.
• Severe allergic reactions (swelling of face, tongue, throat — difficulty breathing).

Who Should Not Take Levitra Generic

Vardenafil is contraindicated in men who:

• Take nitrate medications in any form
• Take Class IA or Class III antiarrhythmic medications (quinidine, procainamide, amiodarone, sotalol)
• Take riociguat (Adempas)
• Have severe cardiovascular disease or recent heart attack or stroke (within 6 months)
• Have severe hepatic impairment
• Have hereditary degenerative retinal disorders (retinitis pigmentosa)
• Have uncontrolled hypotension or hypertension
• Have a history of non-arteritic anterior ischaemic optic neuropathy (NAION)
• Are women or children — Vardenafil for ED is indicated for adult males only

Frequently Asked Questions — Levitra Generic in Australia

Is Vardenafil the same as Levitra in Australia? Yes. Vardenafil is the active ingredient in Levitra. Levitra Generic contains the same Vardenafil at the same dosage as brand Levitra from Bayer — with identical pharmacological action, onset, duration, efficacy, and side effects. Bioequivalence to the brand product is required by law before generic registration.

Is Levitra better than Viagra in Australia? For specific Australian men — yes. Levitra Generic (Vardenafil) has a faster onset (15–30 min vs 30–60 min for Sildenafil), is not significantly affected by food, does not cause visual colour disturbances, and has the most extensive clinical evidence in men with diabetes and post-prostatectomy ED. For first-time users wanting the lowest cost, Viagra Generic (Sildenafil) is still the standard recommendation. Many Australian men try both and find one works better for them personally.

How long does Levitra last in Australia? 4 to 6 hours — the same as Viagra Generic (Sildenafil). For a longer-lasting option, Cialis Generic (Tadalafil) offers up to 36 hours. Levitra's advantage over Viagra is onset speed and food resistance, not duration.

Can I take Levitra after a meal in Australia? Yes — this is one of Vardenafil's key practical advantages. Unlike Sildenafil (Viagra) which is significantly slowed by high-fat meals, Vardenafil absorption is minimally affected by standard meals. For Australian men who want reliable, fast-onset ED medication after dinner — Vardenafil is the most predictable choice among classic PDE5 inhibitors.

Is Levitra suitable for Australian men with diabetes? Yes — Vardenafil has the most extensive clinical evidence base of any PDE5 inhibitor specifically in diabetic populations. Clinical trials in men with type 1 and type 2 diabetes show 57% successful intercourse attempts with Vardenafil 10 mg versus 23% with placebo. Australian men with diabetes who have not responded adequately to Sildenafil are frequently switched to Vardenafil.

Does Levitra cause colour vision problems like Viagra? No. Visual colour disturbances (blue tinge, light sensitivity) are a known side effect of Sildenafil (Viagra) due to its cross-reactivity with PDE6 — a retinal enzyme. Vardenafil is significantly more selective for PDE5 over PDE6, and visual colour disturbances are not a reported side effect of Levitra Generic.

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

Is Levitra safe with heart medications? Vardenafil has an important and unique contraindication: it must never be combined with Class IA antiarrhythmics (quinidine, procainamide) or Class III antiarrhythmics (amiodarone, sotalol) due to additive QT interval prolongation and cardiac arrhythmia risk. This contraindication is more significant for Vardenafil than for Sildenafil or Tadalafil. Australian men taking any heart rhythm medication must inform their cardiologist or GP before using Vardenafil. As with all PDE5 inhibitors, nitrates in any form are an absolute contraindication.

How long does delivery of Levitra Generic to Australia take? Standard delivery to all Australian states and territories takes 4 to 9 business days. Express shipping is also available. All orders are delivered in plain, unmarked packaging with a tracking number.

Will Levitra Generic be stopped at Australian customs? Shipments from international sources carry a risk of inspection by Australian Border Force. Under the TGA Personal Importation Scheme, personal-use quantities (up to 3 months' supply) are generally permitted. All shipments from RedstoneRX are sent in plain, unmarked packaging with no reference to the contents. A tracking number is included with every order.
