Basic product information

Priligy (dapoxetine) is an oral medicine. Dapoxetine is part of a class of drugs known as selective serotonin reuptake inhibitors (SSRIs), designed specifically for the treatment of premature ejaculation.

In the UK, Priligy is used as a targeted therapy for men who experience ejaculation earlier than they want, causing distress and affecting sexual satisfaction.

Strengths commonly available: 30 mg and 60 mg tablets (dose availability can vary by supplier/pharmacy).

How Priligy works (mechanism of action)

Dapoxetine increases levels of serotonin in the brain by blocking its reuptake (it is an SSRI). Serotonin plays a role in sexual function, including ejaculation timing.

• Slows ejaculation reflex: Helping extend time to ejaculation.
• Improves control and reduces urgency: For many men, ejaculation becomes less “sudden.”
• Works on nerve signalling involved in ejaculation: The effect is related to serotonin-dependent pathways.

Individual responses vary. Some men notice benefits after the first few doses, while others may need several doses to see the full effect.

Pharmacokinetics (how the body handles dapoxetine)

Pharmacokinetics describes absorption, distribution, metabolism, and excretion—how your body processes the medicine.

• Absorption: Dapoxetine is absorbed after oral administration. Food can affect absorption (see “Food interactions”).
• Time to peak effect: Dapoxetine generally reaches its highest blood levels within a few hours after taking a dose.
• On-demand use: The medicine is designed for taking before sexual activity rather than daily long-term dosing.
• Metabolism: Primarily metabolised by the liver (notably via CYP enzymes).
• Elimination: Excreted mainly as metabolites through urine and faeces.

Because dapoxetine is processed by the liver and can influence serotonin pathways, it may interact with other medicines and may be unsafe for some people (particularly those with liver or certain heart conditions).

Typical use and timing

Priligy is commonly used “as needed” prior to sexual activity.

When to take it

• Take Priligy about 1 to 3 hours before sex (follow your local prescribing instructions).
• Do not take multiple doses within a short period.

How often

• Maximum frequency: Do not exceed the maximum daily dose stated on your medicine information or as advised by a healthcare professional.
• Many product instructions limit use to avoid side effects.

Practical tip: Choose a consistent timing for your first few doses so you can learn how your body responds.

Indications (what it is used for)

Priligy is indicated for the treatment of premature ejaculation in adult men.

Premature ejaculation generally refers to ejaculation that occurs sooner than desired, often accompanied by a lack of control and distress. Your clinician will usually confirm the diagnosis and discuss whether dapoxetine is appropriate.

Dosing (general guidance)

Dosing can vary based on your health status, tolerability, and potential drug interactions. The typical approach is to start at a lower dose and adjust if needed.

Common starting strategy

• Initial dose: Often 30 mg to help reduce the chance of side effects.
• If tolerated: Your clinician may consider increasing to 60 mg for stronger effect.

Missed dose

Because Priligy is taken before sexual activity, a “missed dose” usually means you simply do not take it at another time. Use it only according to the timing advice given for your situation.

Special populations

• Older adults: May be more sensitive to side effects such as dizziness. Extra caution is recommended.
• Kidney problems: Dose suitability may vary.
• Liver problems: Priligy may be unsuitable in moderate to severe liver disease.

Food interactions

Food can affect how dapoxetine is absorbed. For many patients, taking Priligy with a heavy meal may delay absorption and change how quickly you feel the effect.

• General guidance: Many dosing instructions advise taking it with or without food, but timing consistency is important.
• Practical advice: If you notice delayed effect, try taking it in a more predictable way (for example, with a similar meal pattern each time) and discuss your experience with a pharmacist/clinician.

If you have experienced nausea or dizziness, some people find it easier to take the tablet with a light snack—however follow your official product instructions or professional advice.

Alcohol interactions

Combining Priligy with alcohol can increase the likelihood of dizziness, drowsiness, or feeling faint. Dapoxetine may affect blood pressure regulation in some people, and alcohol can worsen this effect.

• Avoid heavy drinking around the time you take Priligy.
• Do not drive or operate machinery if you feel dizzy or unwell.
• If you get symptoms such as light-headedness, sit or lie down and seek advice.

If you want to drink, keep it minimal and be cautious. Discuss your plan with a healthcare professional, especially if you have a history of fainting or low blood pressure.

Medicine interactions (very important)

Because dapoxetine affects serotonin levels and is metabolised by liver enzymes, it can interact with several types of medicines. Always check interactions with a pharmacist before combining Priligy with any new medicine.

Common interaction categories

• Other antidepressants (especially SSRIs/SNRIs/MAO inhibitors): increased risk of serotonin-related side effects.
• MAO inhibitors (and recent use): typically incompatible due to serious interactions.
• Linezolid or methylene blue: may increase serotonin-related risks.
• Triptans (migraine treatments): combined use may increase serotonin risk.
• Strong CYP inhibitors (some antifungals and certain antibiotics): can raise dapoxetine levels, increasing adverse effects.
• Medicines affecting heart rhythm: may increase safety risks, including QT-related effects.
• Other drugs that can lower blood pressure: may increase dizziness/light-headedness.

Do not start or stop antidepressants abruptly

If you take any antidepressant medicines, do not change them without medical guidance. Sudden changes can cause withdrawal symptoms or affect serotonin balance.

Herbal and supplement interactions

• St John’s wort may affect serotonin pathways and dapoxetine levels.
• Other supplements may also interact—check with a pharmacist.

Safety reminder: If you are taking multiple medicines, it’s helpful to keep an up-to-date list and review it with a clinician or pharmacist before using Priligy.

Safety profile

Like all medicines, Priligy can cause side effects. Many are mild and improve as your body adapts, but some require urgent attention.

Common side effects

These are the most frequently reported effects, typically during early use:

• Nausea
• Dizziness or light-headedness
• Headache
• Diarrhoea
• Insomnia or sleep disturbance
• Fatigue

Less common but important risks

• Fainting (syncope): particularly in people predisposed to low blood pressure.
• Blood pressure changes: dizziness on standing may occur.
• Serotonin-related reactions: symptoms such as agitation, sweating, tremor, fever, confusion, or severe diarrhoea may indicate a serious condition.
• Heart rhythm issues: rarely, dapoxetine may affect the electrical activity of the heart in susceptible individuals.

When to seek urgent medical help

Stop using Priligy and seek urgent help if you experience:

• Severe dizziness, fainting, or collapse
• Signs of a serious allergic reaction (swelling of face/lips, difficulty breathing)
• Symptoms suggestive of serotonin syndrome (high fever, severe agitation, confusion, rigid muscles, rapid heart rate)
• Chest pain, severe shortness of breath, or palpitations that feel unusual or severe

Who should be extra cautious or may not be suitable

Priligy may not be suitable if you have certain medical conditions or take certain medicines. Examples include:

• Moderate to severe liver impairment
• Certain heart rhythm problems or history of fainting related to blood pressure
• Concurrent use of interacting medicines (see interaction section)

If you have any history of mental health conditions or seizures, tell your clinician or pharmacist before using dapoxetine.

Practical use tips (to get the best experience)

• Start low, go slow: If you are advised to begin at 30 mg, give your body time to adjust.
• Learn your timing: Many men benefit from taking it 1–3 hours before sex. Adjust within the advised range if your first experience is too early or too late.
• Stay hydrated: Dehydration can worsen headaches and dizziness.
• Be cautious when standing up: If dizziness occurs, rise slowly.
• Avoid heavy alcohol: Alcohol can worsen side effects and reduce control.
• Don’t combine with incompatible medicines: Review your full list of medicines (including migraine treatments and antidepressants) with a pharmacist.
• Manage anxiety: Stress and performance anxiety can worsen PE. Behavioural techniques and reassurance often complement medication.

Alternative options for premature ejaculation (UK)

If Priligy is not suitable or does not work well enough, there are other approaches.

Behavioural techniques

• Start-stop techniques: pausing stimulation to regain control.
• Squeeze techniques: applying pressure to reduce arousal (may help some men).
• Pelvic floor exercises: strengthening can improve control over ejaculation.

Other medication approaches

There are other prescription options and off-label strategies used in some settings, depending on local guidance and individual circumstances. A clinician can advise based on your health history and the likely benefit-risk balance.

Topical options

• Local anaesthetic sprays/creams may reduce sensitivity for some men.
• They may be used with caution to avoid reduced sensation for a partner.

Note: Alternative options should be chosen with a clinician’s help, particularly where medical conditions, heart rhythm risks, or antidepressant use are involved.
