Mechanism of Action
For Patients: Tadalafil is a medicine that works by increasing blood flow to certain parts of the body. In men, it’s used to treat erectile dysfunction (ED). Research has suggested it may improve sexual satisfaction, arousal, and blood flow for some women with sexual dysfunction, though it’s not formally approved for this use in Australia.
Specialist Detail: Tadalafil is a selective inhibitor of phosphodiesterase type 5 (PDE5). By blocking this enzyme, it prevents the breakdown of cyclic guanosine monophosphate (cGMP), leading to relaxation of smooth muscle and increased blood flow, particularly in the pelvic region. In women, the proposed benefit involves enhanced genital blood flow, lubrication, and genital sensitivity, though robust clinical data are still emerging.
Pharmacokinetics
- Absorption: Rapidly absorbed after oral administration; peak plasma concentration within 2 hours (range: 0.5–6 hours).
- Metabolism: Primarily metabolised by hepatic CYP3A4 enzymes.
- Elimination: Mainly via faeces (61%); small proportion in urine (36%).
- Half-life: 17.5 hours (long half-life allows for daily or “on-demand” use).
- Duration of Action: Up to 36 hours; sometimes called “the weekend tablet.”
Use in Everyday Life and Best Practices
- Typical Doses for Women (Research Use): For investigational purposes in female sexual dysfunction, doses of 5–10 mg daily or 10–20 mg taken before anticipated sexual activity have been studied. Note: Always follow your doctor’s advice.
- How to Take: Swallow tablet whole with water, once daily or as directed. Can be taken with or without food.
- English Context: Discuss with a GP or sexual health specialist with experience in female sexual health. Unregistered use (off-label) can only be prescribed by a medical professional.
- Duration: Take for as long as recommended by your doctor; review efficacy and side effects regularly.
Dosing in the Morning vs. Evening
- Morning: May help if sexual activity is anticipated during the day; maintains steady levels.
- Evening: Convenient for those who expect sexual activity at night; reduces drowsiness concerns.
- Tips: Try to take at approximately the same time each day to maintain regular effects.
- Advantages/Disadvantages: No significant difference in efficacy; choose the time that best fits your lifestyle.
Taking with Food or on an Empty Stomach
- Tadalafil can be taken with or without food.
- Fat-rich English or multicultural Australian meals do not significantly delay absorption or effectiveness.

Guidelines for Proper Use
- Always use as prescribed; never exceed the dose recommended by your doctor.
- Discuss medical history and all medications with your GP before starting.
- Do not combine with other ED therapies or nitrates.
- If you experience chest pain, sudden vision change or dizziness, seek urgent medical attention.
- Women who are pregnant, planning pregnancy, or breastfeeding should not use without maternity specialist advice.
- Store below 25°C, protect from moisture and sunlight. Follow Australian medicine disposal rules for unused tablets.
Alternative Treatment Options
- Pharmacotherapy: There are no approved drug alternatives for female sexual dysfunction in Australia; flibanserin and bremelanotide are not registered with the TGA.
- Non-pharmacological:
- Psycho-sexual counselling (referral via Medicare)
- Pelvic floor physical therapy
- Lubricants and vaginal moisturisers (available OTC)
- Hormonal therapy (for postmenopausal symptoms – as per specialist recommendation)
- Comparative notes: Tadalafil is investigational for women. Counselling and lifestyle interventions remain first-line and are widely accessible in Australia.
Legal, Registration & Reimbursement Status in Australia
- Tadalafil is a Schedule 4 prescription medicine, regulated by the Therapeutic Goods Administration (TGA).
- Use for ED and PAH is TGA-approved.
- Use for female sexual dysfunction is “off-label”; only via individual prescriber responsibility with fully informed patient consent.
- Tadalafil for ED may be partially subsidised under the Pharmaceutical Benefits Scheme (PBS) for some indications; not subsidised for use in women.
- Medicines must be supplied by registered Australian pharmacies.
Latest Research & Clinical Guidance (2022–2025)
- Recent English and international studies (e.g., Journal of Sexual Medicine, 2023–2024) suggest Tadalafil may improve some aspects of sexual satisfaction and arousal in selected women, especially those with vascular or psychogenic causes, but benefits are modest and data are limited.
- Guidelines from the Royal Australian College of General Practitioners (RACGP) state that off-label use of Tadalafil for women should only be considered after multidisciplinary assessment and counselling, and only where benefit outweighs risk.
- Ongoing clinical trials (NCT, 2022–2025) are exploring expanded indications, but Tadalafil is not a mainstream therapy for female sexual dysfunction in Australia as of 2024.
