Overview of PE Medications

1. Dapoxetine (Priligy®) — On-Demand SSRI

The only medication specifically developed for PE.

• Type: Short-acting SSRI
• Dosing: 30 mg or 60 mg, taken 1–3 hours before sexual activity
• How it works: Rapidly increases serotonin to raise the ejaculatory threshold
• IELT improvement: 2.5–3× from baseline (Li J et al. Clin Ther. 2014;36(12):2003-2014. PMID: 25438723)
• Key advantage: On-demand dosing; rapid onset and clearance
• Key limitation: Less potent than chronic SSRIs for IELT extension

2. Daily SSRIs (Off-Label)

Antidepressants repurposed for PE.

Common options include: - Paroxetine: Considered the most effective SSRI for PE(Based on clinical guidelines and prescribing information) - Sertraline: Good balance of efficacy and side effects(Based on clinical guidelines and prescribing information) - Fluoxetine: Longer half-life; may be less effective(Based on clinical guidelines and prescribing information) - Citalopram/Escitalopram: Sometimes used with reasonable efficacy(Based on clinical guidelines and prescribing information)

• Dosing: Daily, with full effect taking 1–2 weeks
• How they work: Chronically elevated serotonin raises the ejaculatory threshold
• IELT improvement: 3–8× from baseline(Based on clinical guidelines and prescribing information) — potentially greater than dapoxetine
• Key advantage: Greater IELT improvement for some men; good for frequent sexual activity
• Key limitation: Daily dosing required; broader side-effect profile; discontinuation symptoms

3. Topical Anaesthetics

Numbing agents applied to the penis.

• Products: Lidocaine/prilocaine spray (e.g., EMLA, Fortacin), benzocaine wipes
• Dosing: Applied 10–20 minutes before intercourse
• How they work: Reduce penile nerve sensitivity
• IELT improvement: 1.5–2×(Based on clinical guidelines and prescribing information)
• Key advantage: No systemic side effects; available without prescription in some formulations
• Key limitation: Must be timed carefully; can transfer to partner causing numbness; reduced sensation

4. Tramadol (Off-Label)

An opioid analgesic with serotonergic properties.

• Dosing: 25–50 mg, taken 1–2 hours before activity(Based on clinical guidelines and prescribing information)
• IELT improvement: Moderate(Based on clinical guidelines and prescribing information)
• Key advantage: May work when SSRIs don't
• Key limitation: Risk of dependence; sedation; not first-line; regulatory concerns

Head-to-Head Comparison

Choosing the Right Treatment

Choose Dapoxetine If:

• You want a treatment specifically designed for PE
• You prefer on-demand dosing (take it only when you need it)
• You don't want to take daily medication
• You want rapid onset with minimal lingering effects
• International guidelines recommend it as first-line (Althof SE et al. Sex Med. 2014;2(2):60-90. PMID: 25356302)

Choose Daily SSRI If:

• You have very frequent sexual activity and prefer continuous coverage
• Dapoxetine alone doesn't provide sufficient improvement
• You also have depression or anxiety that would benefit from treatment
• You're comfortable with daily medication and the broader side-effect profile

Choose Topical Anaesthetic If:

• You prefer a non-oral option
• You want to avoid systemic medication entirely
• Your PE is mild and related to penile hypersensitivity
• You're comfortable with reduced sensation

Combined Approach:

Some doctors may recommend combining treatments — for example, dapoxetine plus a topical anaesthetic, or medication plus behavioural therapy. This multi-modal approach is supported by the ISSM guidelines (Althof SE et al. Sex Med. 2014;2(2):60-90. PMID: 25356302).

Side-Effect Profiles

Dapoxetine

• Nausea (10–15%), headache (5–10%), dizziness (5–8%)
• Generally mild and transient
• No sexual side effects (libido, erection unaffected)
• No withdrawal or discontinuation syndrome

Daily SSRIs

• Nausea, headache, fatigue (common during initiation)
• Sexual side effects: Reduced libido, erectile difficulty, delayed orgasm (10–30%)(Based on clinical guidelines and prescribing information)
• Weight changes possible(Based on clinical guidelines and prescribing information)
• Discontinuation syndrome if stopped abruptly: dizziness, nausea, irritability, "brain zaps"(Based on clinical guidelines and prescribing information)

Topical Anaesthetics

• Local numbness (desired effect, but can be excessive)
• Potential transfer to partner
• Skin irritation in some individuals(Based on clinical guidelines and prescribing information)
• No systemic side effects

Tramadol

• Drowsiness, nausea, constipation
• Dependence potential with regular use
• Drug interactions with SSRIs (serotonin syndrome risk)(Based on clinical guidelines and prescribing information)

What About Behavioural Therapy?

Medication works best when combined with behavioural strategies:

• Stop-start and squeeze techniques: Teach you to recognise and manage the point of no return
• Mindful sex practices: Focusing on sensation rather than performance
• Cognitive behavioural therapy (CBT): Addresses performance anxiety and negative thought patterns
• Couples therapy: Improves communication and reduces relationship tension

The ISSM recommends combining pharmacotherapy with psychological intervention for optimal outcomes (Althof SE et al. Sex Med. 2014;2(2):60-90. PMID: 25356302).

Frequently Asked Questions

1. Can I switch between different PE medications?

Yes, under medical supervision. If dapoxetine isn't effective or well-tolerated, your doctor may suggest a daily SSRI or a combined approach.

2. Can I use topical anaesthetic AND dapoxetine together?

This combination is sometimes used for men who need additional help. Discuss with your doctor first.

3. How long does it take to know if a treatment is working?

Dapoxetine: improvement from the first dose. Daily SSRIs: 1–2 weeks for initial effect, 4–6 weeks for full effect(Based on clinical guidelines and prescribing information). Topicals: immediate effect on first use.

4. Are generic versions of dapoxetine available in Hong Kong?

Generic dapoxetine formulations may be available and are typically more affordable than branded Priligy(Based on clinical guidelines and prescribing information). Your noah™ doctor will prescribe the most appropriate option.

5. Will I need medication forever?

Not necessarily. Some men use dapoxetine during a period of sexual confidence-building and eventually find they need it less frequently. Others prefer to have it available as needed long-term. There's no wrong approach — it's about what works for you.
