Malegra FXT (Sildenafil/Fluoxetine): Patient Information for Australians
Basic Product Information
| International Non-proprietary Name (INN) | Sildenafil & Fluoxetine |
|---|---|
| Australia Brand Names | Malegra FXT (not an officially registered brand in Australia; sourced internationally) |
| ATC Code | G04BE03 (Sildenafil); N06AB03 (Fluoxetine; combined formulation not currently assigned unique ATC code in AU) |
| Available Forms and Strengths | Tablets: Usually 100mg Sildenafil / 40mg Fluoxetine per tablet |
| Manufacturers | Sunrise Remedies, India (most common international supplier; not TGA-listed in Australia) |
| Prescription Status | Prescription Only in Australia for both active substances; consult your GP or urologist before use. |
Mechanism of Action
In simple terms:Malegra FXT combines two active medications:
- Sildenafil: This is a type of medicine called a PDE5 inhibitor, which helps increase blood flow to the penis during sexual stimulation, assisting men with erectile dysfunction (ED).
- Fluoxetine: A well-known antidepressant in the SSRI (selective serotonin reuptake inhibitor) class, used both for mood disorders and, off-label, to help manage premature ejaculation (PE) by increasing serotonin in the brain and delaying ejaculation.
Sildenafil inhibits phosphodiesterase type 5 (PDE5), enhancing NO-mediated smooth muscle relaxation and increased penile blood inflow during sexual stimulation. Fluoxetine blocks the reuptake of serotonin at synaptic clefts, prolonging its action and modulating ejaculatory latency.
Pharmacokinetics
- Absorption:
- Sildenafil: Rapid, peak plasma levels in ~1 hour
- Fluoxetine: Readily absorbed, peak in 6–8 hours
- Metabolism:
- Sildenafil: Hepatic via CYP3A4/2C9
- Fluoxetine: Hepatic via CYP2D6 (and its active metabolite norfluoxetine—very long half-life)
- Elimination:
- Sildenafil: Mainly by liver and kidney, t½ ~4 hours
- Fluoxetine: t½ ~1–3 days, norfluoxetine t½ ~4–16 days
- Duration of Action:
- Sildenafil: 4–6 hours
- Fluoxetine: Steady therapeutic state may take multiple days (for PE, acute effect can occur within hours)
Use in Everyday Life and Best Practices (in Australia)
Both parts of Malegra FXT are used to help men who experience erectile dysfunction (ED) and premature ejaculation (PE). While the product is not currently registered for supply in Australia, your GP or urologist may discuss similar medicines that are TGA-approved.
Typical doses:- Malegra FXT: 1 tablet (100mg Sildenafil and 40mg Fluoxetine) taken with water, about 30-60 minutes before sexual activity (not more than once per day).
How to use:
- Take the tablet whole, with a full glass of water.
- Time the dose for planned intimacy (about 1 hour beforehand for best results).
- If prescribed for regular use, try to take it at the same time of day.
- Do not double dose; if you miss a dose and it is near the next, skip and continue as normal.
Dosing in the Morning vs Evening
- Morning: May be preferable for men planning sexual activity earlier in the day or seeking a routine to manage premature ejaculation with fluoxetine’s SSRI effect.
- Can result in more stable fluoxetine levels over time.
- May interfere less with sleep for some patients.
- Evening: Often chosen when intimacy is likely later in the day.
- Risk of sleep disturbance (fluoxetine can sometimes cause insomnia).
- Ensure not to mix with heavy alcohol intake common in late evenings.
Tip: Consistency is helpful. Pick a regular time that matches your needs and is easy to remember. Discuss your routine with your doctor or pharmacist.
Taking with Food or on an Empty Stomach
Sildenafil is best absorbed on an empty stomach—it works faster and more effectively if you avoid high-fat foods beforehand. Fluoxetine is less affected by food.
- With Food:
- May slow down onset of sildenafil (fatty English breakfast, heavy evening meal can delay results).
- Not recommended if fast action is needed.
- On an Empty Stomach:
- Faster absorption and effect (aim for at least 2 hours after eating for best sildenafil action).
If you have a sensitive stomach, you may take the tablet with a small snack (not high in fat), but expect a potential delay in effect.

Legal, Registration, and Reimbursement Status in Australia
- Malegra FXT is not registered for general supply by the Therapeutic Goods Administration (TGA) in Australia.
- Individual components (sildenafil, fluoxetine) are approved but not in combination.
- Imported use may fall under the TGA’s Personal Importation Scheme, but risks counterfeit/quality concerns.
- Prescription is required for both sildenafil and fluoxetine in Australia.
- Sildenafil for ED is not covered on the PBS (Pharmaceutical Benefits Scheme) without a special indication.
- Fluoxetine is funded by PBS only for depression and some mental health conditions.
Latest Research and Clinical Guidance (2022–2025)
- Recent English and European studies (e.g., European Urology, 2023; BJU International, 2024) confirm the efficacy of dual therapy in men with both ED and PE, but safety and regulatory guidance stresses the importance of individualised treatment and monitoring for serotonin syndrome and hypotension.
- Australian guidelines (Therapeutic Guidelines: Sexual and Reproductive Health, 2023) recommend the use of single therapy unless dual symptoms are carefully assessed and other options trialled; SSRIs (fluoxetine, paroxetine) may be considered off-label for PE.
- Emerging evidence supports the careful use of combination therapies for men where single-drug treatments for ED or PE have failed, but only under specialist supervision.

FAQ – Patient Questions and Answers
- Is Malegra FXT safe to use in Australia?
Malegra FXT is not registered by the TGA, so its safety and quality are not officially guaranteed in Australia. The individual ingredients are approved in single forms; discuss combination therapy and sourcing with your GP first. - Can I use Malegra FXT if I have other medical conditions?
Caution is essential. Malegra FXT should be avoided in people with severe heart, liver, or kidney disease, or those taking nitrates, alpha-blockers, or other antidepressants. Talk to your doctor about all of your medications and conditions. - Can I drink alcohol or eat normally while using Malegra FXT?
Alcohol can increase side effects—limit or avoid. Large or fatty meals can reduce sildenafil’s effectiveness—aim for lighter meals when dosing. - Do I need a prescription to obtain this medicine?
Yes, prescriptions are mandatory in Australia for both sildenafil and fluoxetine—combination products should not be self-ordered without doctor supervision. - Are there safer TGA-approved alternatives in Australia?
Yes. Separately prescribed sildenafil (for ED) and fluoxetine or paroxetine (for PE) are available in Australia under medical supervision, and represent the preferred, safer alternatives.
