General a quick outline and notable facts
Active segments present in the formulation: tadalafil and dapoxetine combined in a single tablet.
Use as intended: treatment for adult men with erectile dysfunction (ED) together with on-demand management of premature ejaculation (PE). The formulation puts a long-acting phosphodiesterase type 5 inhibitor together with a short-acting serotonin reuptake agent to target both conditions in the same encounter.
Typical strength: one marketed formulation contains tadalafil 20 mg together with dapoxetine 60 mg in each tablet.

Biological the way it works of action
Tadalafil action
Tadalafil works by inhibiting PDE5 which increases blood flow to the penis during sexual stimulation. This supports the ability to get and keep an erection. In many users the effect on erectile function can last for up to around 36 hours following a single dose.
Dapoxetine action
Dapoxetine is a short-acting selective serotonin reuptake inhibitor used on demand for premature ejaculation in men aged 18 to 64. It tends to increase the time to ejaculation by altering serotonergic signalling involved in ejaculatory control.
Practical use instructions
Follow the advice of your prescriber or pharmacist. The following points are general guidance only.
- Swallow the tablet in one piece with water.
- Take the tablet about 30 to 40 minutes before sexual activity is expected.
- It can be taken with or without food, but large high-fat meals may slow how fast it starts to work.
- Avoid alcohol and grapefruit or grapefruit juice when possible due to contact and response potential and elevated damaging effects.
- Note that the two active components have different time to peak effect: tadalafil often acts within 20 minutes in some men, dapoxetine commonly reaches peak effect at around 40 to 50 minutes. Plan timing accordingly.
If you are unsure about timing or whether this medicine suits you, discuss options in collaboration with your prescriber. See dosing and timing further details are available.
Timing of dosing
Use the lowest effective dose for the shortest duration necessary, as advised by a clinician.
- Common fixed-dose tablet: tadalafil 20 mg plus dapoxetine 60 mg taken as needed before sexual activity.
- Do not take more than one tablet within 24 hours. Because tadalafil persists in the body, your prescriber may recommend spacing doses further apart in some cases.
- If you forget to take a planned dose, take it when you remember only if sexual activity is still intended that day. Only one dose should be taken at a time.
- Some patients require separate prescriptions for tadalafil and for a PE treatment at different doses. Your clinician may tailor therapy depending on medical history and co-medication.
Archival data at rest resides in storage until it is accessed. and handling instructions
- Store between 20 and 25 degrees C (68 and 77 degrees F).
- Keep in a dry place away from direct heat and strong light.
- Keep out of the reach and sight of children and animals.
Major positive the give and take of interactions enhance user satisfaction.
There are several medicines and substances that can interact with either tadalafil or dapoxetine. Always tell your prescriber about all medicines, supplements, and recreational drugs you use.
- Nitrates or nitric oxide donors (for example glyceryl trinitrate, isosorbide dinitrate, nitroprusside, or "poppers"): combining these can cause a dangerous fall in blood pressure and is contraindicated.
- Alpha-blocking agents and some blood pressure medicines: may add to blood pressure lowering and cause dizziness or fainting; careful adjustment and timing may be required.
- Strong CYP3A4 inhibitors (for example ketoconazole, itraconazole, ritonavir, cobicistat, clarithromycin): can increase levels of tadalafil and possibly dapoxetine; dose changes or avoidance may be necessary.
- CYP3A4 inducers (for example rifampicin, carbamazepine, phenytoin, Hypericum perforatum, the St Johns wort herb): may lower effectiveness by increasing clearance.
- Other serotonergic drugs (such as SSRIs, SNRIs, MAO inhibitors, linezolid, lithium, triptans): combined use with dapoxetine raises the risk of serotonin syndrome.
- Ethanol solution: increases risk of dizziness, fainting, pain in my head and impaired judgment. Limit your drinking to moderate levels.
- Other erectile dysfunction medicines or local therapies: keep these separate; do not combine them. without medical advice.

Alternative options and analogous treatments
If the fixed-dose combination is unsuitable, clinicians may recommend using single agents or different strategies. Choice should be tailored to medical history, medication interplay between parties alerts, preferences and tolerability.
Treatment avenues for erectile dysfunction
- Tadalafil alone - available as on-demand 10 to 20 mg or lower-dose daily regimes (2.5 to 5 mg).
- Sildenafil (generic or brand Viagra) - shorter duration of action, commonly used first-line.
- Vardenafil (Levitra) - similar onset and duration to sildenafil for some patients.
- Avanafil branded Spedra - may have a faster onset; availability depends on local pharmacy stock.
- Non-oral approaches - vacuum erection devices or intracavernosal injections such as alprostadil for men who cannot take or do not respond to oral drugs.
Methods for dealing with premature ejaculation
- Dapoxetine taken on demand where it is legally supplied.
- Topical numbing agents (lidocaine/prilocaine creams or sprays) to reduce penile sensitivity.
- Behavioural techniques such as stop-start or squeeze methods, and pelvic floor training.
- Off-label oral SSRIs prescribed by a doctor, for example sertraline or paroxetine, usually as daily therapy.
Discuss these more options with an Australian registered prescriber to agree the safest option. For links to fee schedule and availability, see rough cost range and jurisdictional legal considerations.

Considerations under Australian law
- Tadalafil is classified as a Prescription Only (Schedule 4) medicine in Australia and requires a prescription from an Australian-registered prescriber for lawful supply.
- Dapoxetine and some fixed-dose combinations may not be listed on the Australian Register of Therapeutic Goods (ARTG) for routine supply; this restricts availability in Australian drugstore chains.
- Personal importation: the Therapeutic Goods Administration (TGA) Personal Importation Plan may allow individuals to import up to a three-month personal supply in limited circumstances, typically requiring a valid prescription and compliance with customs. Non-ARTG products can be detained by Border Force or refused entry.
- Advertising and online sales: Australian law limits how prescription medicines can be advertised to the public. Be cautious with overseas websites and sellers because counterfeit and substandard medicines are a significant risk.
- Driving and operating machinery: if you experience dizziness or drowsiness after taking the medicine, do not drive or perform tasks that require full alertness in line with Australian road safety regulations.
For up-to-date guidance consult the TGA website, state health departments, or your pharmacist. If you plan to import medicinesplease check. current TGA and customs rules first.
