Mechanism of Action
Sildenafil is a phosphodiesterase type 5 (PDE5) inhibitor, increasing blood flow in the penis during sexual stimulation—helping with erectile dysfunction (ED). It relaxes blood vessels, allowing for a more natural erection.
Dapoxetine is a selective serotonin reuptake inhibitor (SSRI) registered for the treatment of premature ejaculation (PE). It increases serotonin activity in relevant nerve pathways, helping delay ejaculation and improve control during sexual activity.
Simple Explanation:
- Sildenafil: Improves erections by increasing blood flow.
- Dapoxetine: Helps you last longer by supporting control over ejaculation.
Pharmacokinetics
- Absorption: Sildenafil’s effects begin after 30-60 minutes; Dapoxetine reaches peak concentration within 1-2 hours.
- Metabolism: Both drugs are metabolised mainly in the liver (CYP3A4 pathway), with active metabolites. Liver impairment may affect levels.
- Elimination: Mainly via kidneys (urine) for both substances.
- Duration of Action:
- Sildenafil: lasts 4–6 hours (some effect up to 8 hours)
- Dapoxetine: effective up to ~4 hours after ingestion
Use in Everyday Life and Best Practices
- Typical Doses: 1 tablet (Sildenafil 100mg + Dapoxetine 60mg), as needed, once in 24 hours.
- How to Use: Swallow whole with a glass of water, preferably 1–3 hours before expected sexual activity. Do not split or crush the tablet.
- Australian Context: Safe, confidential consultations with your GP or sexual health clinic are recommended. These medicines are not TGA-registered, so discuss alternatives and obtain legitimate prescriptions.
- Do not take more than one tablet within 24 hours.
- If you forget to take a dose, skip it—never double up.
- Do not use without a valid prescription and regular follow-up with your practitioner.
Dosing in the Morning vs Evening
- Evening Use (Most Common): Generally recommended, as sexual activity often occurs at night. Both medicines act within 1–3 hours.
- Morning Use: Not contraindicated, but increased risk of orthostatic effects (dizziness, faintness) on getting up. Consult your doctor if regularly using in the morning.
- Tip: Take your tablet at the same time of day (relative to sexual activity), for best results and minimal side effects.
Taking with Food or on an Empty Stomach
- With Food: High-fat meals (e.g., eggs and bacon, full English breakfast) delay Sildenafil absorption—start may be slower, but overall effect not reduced.
- On Empty Stomach: Effect is faster—onset usually in 30–60 minutes. Avoid large meals if rapid effect is desired.
- Advice: Light meals (toast, fruit, small sandwich) do not significantly affect absorption. Alcohol and fatty meals may increase risk of side effects or delayed onset.
Interaction Warnings
| Interacting Substance | Effect / Risk |
|---|---|
| Nitrates (heart medications) | Dangerous drop in blood pressure (contraindicated) |
| Alpha-blockers (e.g., for prostate) | Possible enhanced low blood pressure, dizziness |
| Alcohol | Increases risk of side effects like dizziness, fainting, reduced efficacy |
| SSRIs / MAOIs / Psychiatric medications | May increase risk of serotonin syndrome (with Dapoxetine) |
| CYP3A4 inhibitors (e.g., ketoconazole, erythromycin, grapefruit juice) | Increases blood levels of both drugs, raising side effect risk |
| CYP3A4 inducers (e.g., rifampicin) | Decreases blood levels of both drugs, reducing benefit |
Always inform your GP or pharmacist of all medicines and supplements you are taking.
Indications
| Official Indications | Treatment of erectile dysfunction (ED) with concurrent premature ejaculation (PE) in adult men (off-label in AU; each compound is separately approved but not the combination). |
|---|---|
| Off-label Uses | Some urologists may prescribe for men with ED plus PE if standard single-agent therapy fails. Always under specialist supervision. |
Dosing According to Clinical Indications
| Patient Group | Starting Dose | Maximum Dose / Interval |
|---|---|---|
| Adult men (18–64 yrs) | 1 tablet, as needed 1–3h before sexual activity | Not more than once in 24h |
| Elderly (65+) | Special caution – start with lowest possible dose | Not more than once in 24h, and only under physician advice |
| Paediatric (under 18) | Not recommended. Safety and efficacy not established. | Contraindicated |
| Renal/liver impairment | Use with caution; consult specialist | Lower starting doses may be indicated |
Safety Profile and Side Effects
The combination is usually well tolerated but some side effects may occur. Most are mild and transient.
| Frequency | Side Effect |
|---|---|
| Very common (>10%) | Headache, facial flushing, nausea, dizziness |
| Common (>1-10%) | Indigestion, diarrhoea, nasal congestion, back pain, insomnia, mild vision changes, dry mouth |
| Uncommon (>0.1-1%) | Palpitations, anxiety, light-headedness, raised blood pressure, prolonged erection (>4h, priapism), blurred vision |
| Rare (<0.1%) | Severe allergic reactions, chest pain, fainting, serotonin syndrome (with Dapoxetine), seizures |
- If an erection lasts longer than 4 hours, seek immediate medical help (can cause permanent damage).

- Limit alcohol; avoid recreational drugs while on therapy.

- Sildenafil (Viagra, generic) – TGA-approved, widely available, PBS-listed for some patients
- Tadalafil (Cialis, generic) – longer acting, TGA-approved, some PBS coverage
- Vardenafil (Levitra)
- Avanafil (Spedra)

Legal, Registration, and Reimbursement Status in Australia
- Regulator: Therapeutic Goods Administration (TGA)
- Cenforce D: Not registered with TGA for supply in Australia as of June 2024.
- Prescription: Required for both components per PBS and TGA legislature.
- PBS Reimbursement: Sildenafil and Tadalafil approved for select patients under PBS; Dapoxetine is not yet subsidised.
- Private importation: Patients may legally import small quantities for personal use with a valid prescription (up to 3 months’ supply), subject to TGA Personal Import Scheme compliance.
- Careful consultation with your GP or pharmacist about legal status and availability is strongly advised.
Latest Research and Clinical Guidance (2022–2025)
Recent clinical trials and real-world studies (EU, US, Asia-Pacific) support the efficacy of combined PDE5 inhibitors plus Dapoxetine for men with dual ED and PE (Pharmacotherapy, 2023; International Journal of Impotence Research, 2024). Australian guidelines (Sexual Health Society of Australia, RACGP) recommend single-agent approaches first, with combination therapy reserved for complex cases and always under specialist guidance. Dapoxetine monotherapy is preferred for isolated PE; dual therapy is off-label but used in select populations—especially when single therapy is inadequate (Khera et al., 2023; Bella & Brock, 2024).

Frequently Asked Questions (FAQ)
- Can I buy Cenforce D over the counter in Australia?
No. Cenforce D is prescription-only and not registered with the TGA. Discuss with your GP for suitable, approved alternatives if needed. - Is it safe to combine Cenforce D with alcohol?
It is best to avoid alcohol. Alcohol increases risks of side effects like dizziness and fainting, and may reduce the effectiveness of the medication. - How quickly will Cenforce D start working?
Effects are usually felt within 1 hour if taken on an empty stomach, but can take longer after a large or fatty meal. - Are there lifestyle changes that can help with ED or PE?
Yes: regular exercise, balanced diet, reducing alcohol and tobacco, managing stress, and open communication with your partner all make a difference to sexual health. - What should I do if I get side effects?
Mild symptoms (such as headache or flushing) often pass. For severe symptoms (prolonged erections, chest pain, allergic reaction), seek urgent medical help.
Note: For any further questions or to discuss sexual health concerns, speak with your GP, pharmacist, or accredited sexual health service in your local area.
