Tadapox (Tadalafil with Dapoxetine) – Patient Information (UK)

Tadapox is a combination medicine that contains tadalafil and dapoxetine. It is used to help men with two common conditions occurring together: erectile dysfunction (ED) and premature ejaculation (PE). The tadalafil component supports erections, while dapoxetine helps delay ejaculation.

This page explains how Tadapox works, typical use, timing, food and alcohol interactions, safety information, and practical tips. It is written for patients in the United Kingdom.

Basic product information

• Brand name: Tadapox
• Active ingredients: Tadalafil + Dapoxetine
• Medicinal type: Combination treatment for ED and PE
• Who it may be for: Adult men experiencing both ED and PE
• Common dosing form: Oral tablets (strength depends on local availability)

Note: Always check the exact strength on your pack and follow the instructions provided by your healthcare professional and the product label.

How Tadapox works (mechanism of action)

Tadalafil (ED component)

Tadalafil belongs to a group of medicines called phosphodiesterase type 5 (PDE5) inhibitors. In men, erections occur when blood flow to the penis increases. This process involves nitric oxide (NO), which activates a natural pathway that increases cyclic GMP (cGMP).

• Tadalafil blocks PDE5, an enzyme that breaks down cGMP.
• As a result, cGMP levels remain higher for longer.
• This helps relax blood vessels in the penis and supports blood flow during sexual stimulation.

Important: Tadalafil does not automatically produce an erection. Sexual stimulation is still required.

Dapoxetine (PE component)

Dapoxetine is a selective serotonin reuptake inhibitor (SSRI). Serotonin is a neurotransmitter involved in ejaculation control.

• Dapoxetine helps increase serotonin activity in relevant brain pathways by slowing reuptake.
• This can help increase the time to ejaculation in men with premature ejaculation.

Pharmacokinetics (how the body handles each component)

“Pharmacokinetics” describes absorption, distribution, metabolism, and elimination. Exact times may vary between individuals.

Tadalafil – general PK profile

• Absorption: Tadalafil is absorbed after oral dosing.
• Onset: Effects can begin within about 30–60 minutes in many people.
• Duration: Tadalafil has a long duration of action (commonly described as up to ~36 hours), which is why it is often described as “long-lasting.”
• Metabolism: Primarily metabolised in the liver.
• Elimination: Excreted mainly through bile/feces and, to a lesser extent, urine.

Dapoxetine – general PK profile

• Absorption: Rapid absorption after oral dosing.
• Onset: Dapoxetine is designed for “on-demand” use before sex.
• Metabolism: Metabolised by the liver and other pathways.
• Elimination: Cleared primarily via metabolism, with metabolites removed through urine/feces.

Key takeaway: Because both ingredients have different time profiles, Tadapox is usually taken in a “timed” way around sexual activity (see Timing and how to take Tadapox).

Typical use and what to expect

Tadapox is intended for adult men who have both ED and PE. It may help:

• Improve the ability to get and maintain an erection sufficient for sexual activity.
• Reduce the tendency to ejaculate sooner than desired.

Many men notice some improvement quickly, but individual experiences vary. If symptoms persist, a healthcare professional can advise on whether ongoing treatment is suitable and safe for your situation.

When Tadapox is indicated

In general terms, this combination is used for:

• Erectile dysfunction (difficulty achieving or maintaining an erection)
• Premature ejaculation (ejaculation earlier than wanted, often with limited control)
• Both ED and PE together when combined treatment is appropriate

Not for women.

Dosing (how much and how often)

Always follow the exact dosing instructions on your pack. Below are general patient-friendly guidance points.

Typical “as needed” approach

Tadapox is commonly taken before anticipated sexual activity. The tadalafil component may provide a wider time window, while dapoxetine is designed for more time-specific benefit.

Starting dose and adjustments

• Most people start with a lower strength to assess tolerance.
• Adjustments may be considered based on response and side effects.
• Do not exceed the recommended frequency stated on your label or by your healthcare professional.

Missed dose

If you planned a dose for sexual activity but you do not use it, you typically do not take an extra dose later. Follow the pack guidance for timing of the next tablet.

Swallowing instructions

• Take tablets with water.
• Avoid crushing or splitting unless your specific tablet can be prepared that way (only do so if the product instructions allow it).

Timing and how to take Tadapox

Correct timing helps maximise both components’ benefit.

• Plan ahead: Take Tadapox in advance of sexual activity as directed on the product label.
• Sexual stimulation is required: Tadalafil supports erections but does not create arousal by itself.
• Allow time for effects: Many people find that tadalafil-related effects become noticeable within roughly an hour, but dapoxetine is also intended for pre-activity dosing.

Practical suggestion: Take it at the time recommended for your tablet strength. If you are unsure, check your pack leaflet or ask a pharmacist for advice.

Food interactions

Food can affect the absorption rate of some medicines. With Tadapox, the main considerations are:

• Heavy or fatty meals may delay absorption for some people.
• Delays may shift the onset of effect, particularly for the dapoxetine component.
• If you notice reduced benefit after meals, try taking it with a lighter meal or as instructed on the label.

General approach: Follow the advice on the pack. If your pack says it can be taken with or without food, most people choose a routine that matches their typical meal schedule.

Alcohol and medicine interactions

Combining Tadapox with alcohol can increase the risk of side effects such as dizziness, low blood pressure, and lightheadedness. For safe use:

• Avoid excessive alcohol before and after taking Tadapox.
• If you feel unwell, dizzy, or faint, do not continue sexual activity.
• Be cautious if you are driving or operating machinery the same day, especially if you experience drowsiness.

Medicines that may interact (important)

Tadapox contains two active ingredients that can interact with several medicine classes. Always tell a healthcare professional or pharmacist about all medicines you take, including over-the-counter products and herbal supplements.

1) Nitrates and “nitric oxide donors”

Do not use Tadapox with nitrates (commonly used for chest pain/angina) or medicines that release nitric oxide.

• Example categories: glyceryl trinitrate (GTN), isosorbide medicines, and similar nitrate therapies.
• Combining can cause a dangerous drop in blood pressure.

2) Alpha-blockers (for urinary symptoms or blood pressure)

Using tadalafil with alpha-blockers may increase the risk of low blood pressure, especially at the start of therapy or after a dose change.

3) Blood pressure medicines

Because tadalafil can lower blood pressure, combining with other antihypertensive medicines may increase lightheadedness in some people.

4) Potent CYP3A4 inhibitors/inducers

Tadalafil is metabolised via liver pathways involving CYP enzymes (notably CYP3A4). Some medicines can significantly raise or lower tadalafil levels.

• Examples of potential inhibitors: certain antifungals (e.g., ketoconazole), some antibiotics (e.g., clarithromycin), and some HIV therapies.
• Examples of potential inducers: some anti-seizure medicines and rifampicin-type antibiotics.

These interactions may require dose adjustment or avoidance.

5) Serotonin-related medicines (SSRI interaction risk)

Dapoxetine affects serotonin. Combining with certain medicines can increase the risk of serotonin syndrome, which can be serious.

• Examples: other SSRIs/SNRIs, MAO inhibitors, linezolid, and some migraine therapies (depending on product).

6) “On-demand” ED treatments

Do not combine Tadapox with another PDE5 inhibitor (such as sildenafil, vardenafil, or similar) unless explicitly advised by a healthcare professional.

7) Other relevant considerations

• St John’s wort (a herbal supplement) may affect drug levels and is usually best avoided without professional advice.
• Caution with anticoagulants or medicines affecting clotting: while tadalafil isn’t a blood thinner, individual medicines and health conditions can change risk.

Important: This is not a complete interaction list. Your pharmacist can help check your full medication list for interactions in the UK context.

Safety profile: common and serious side effects

As with all medicines, Tadapox can cause side effects. Many are mild and short-lived, but seek medical advice if symptoms are severe or persistent.

Common side effects

• Headache
• Flushing or feeling warm
• Dizziness
• Nasal congestion
• Nausea or upset stomach
• Indigestion or reflux
• Back pain or muscle aches (more typical with PDE5 inhibitors)
• Dry mouth or other mild SSRI-type effects
• Fatigue or tiredness

Less common but potentially serious effects

• Low blood pressure, fainting, or feeling about to pass out
• Chest pain or severe dizziness (seek urgent help)
• Allergic reactions (rash, swelling of lips/face, difficulty breathing)
• Priapism (an erection lasting longer than recommended). This requires urgent medical attention.
• Serotonin syndrome symptoms such as agitation, confusion, fast heartbeat, sweating, tremor, or fever—seek urgent help.
• Mood changes (especially in those with a history of depression or bipolar disorder)

Who should be extra cautious

Seek professional medical advice before using Tadapox if you have:

• Severe heart disease or recent heart problems
• Low blood pressure or fainting history
• Severe liver impairment
• Severe kidney impairment
• A history of stroke or uncontrolled blood pressure
• Mania/hypomania or significant psychiatric history
• Conditions that make erections unsafe (e.g., certain blood disorders)

Do not use if advised against due to contraindications such as nitrate use or specific serotonin-related medicines.

Practical use tips (to get the best results safely)

• Start conservatively: Use the lowest effective dose first if you’re new to combination therapy.
• Timing matters: Take the tablet at the recommended time before sex, especially if you eat a heavy meal.
• Manage expectations: Tadalafil works better with sexual stimulation. If arousal isn’t present, erections may still be difficult.
• Know your triggers: Stress, lack of sleep, alcohol, and smoking can worsen both ED and PE.
• Hydration and comfort: Staying hydrated may reduce headaches for some people.
• Alcohol caution: Keep alcohol minimal to reduce dizziness and performance variability.
• Plan for side effects: If you feel dizzy after a dose, avoid driving and do not attempt sex until you feel fully normal.
• Monitor response: If you don’t notice benefit after a few appropriate attempts, check with a pharmacist or clinician rather than increasing frequency.

Alternative options for ED and/or PE (UK)

Depending on your main concern and medical history, there are alternatives. Your pharmacist can help you understand what might fit best.

Alternatives for erectile dysfunction

• PDE5 inhibitors without dapoxetine (e.g., tadalafil alone or sildenafil-type options).
• Lifestyle measures: weight management, regular exercise, reducing smoking, moderating alcohol, and managing diabetes/blood pressure.
• Psychosexual support if anxiety or relationship factors contribute.
• Other medical options where appropriate (your clinician may discuss injection therapies or vacuum devices).

Alternatives for premature ejaculation

• Behavioural approaches (e.g., stop-start techniques, pelvic floor exercises).
• SSRI-type medicines used specifically for PE in some cases, guided by clinician advice.
• Topical treatments (numbing sprays/creams) where suitable.

Note: If you have ED and PE separately (or only one condition), using single-ingredient options may sometimes reduce unnecessary side-effect burden. A healthcare professional can recommend the most appropriate approach.

Market and legal context in the UK

In the UK, medicines are supplied under a framework that includes safety monitoring, pharmacy practice rules, and prescribing/dispensing standards for different medicine categories. Availability can depend on whether a medicine is classified as prescription-only or falls under other regulatory routes.

For patient safety, UK online pharmacies typically:

• Ask health questions to assess suitability and detect contraindications.
• Provide medication information about interactions and side effects.
• Offer access to a clinician/pharmacist review where required by regulations and medicine classification.

Always use reputable UK-licensed services and avoid unofficial websites. If you’re unsure whether a seller is legitimate, check their registration and contact details.

Recent guidance and safety awareness (UK-focused)

Patient safety guidance across the UK continues to emphasise:

• Checking drug interactions (especially nitrates and serotonin-related medicines).
• Screening for cardiovascular risk because sexual activity and ED treatments can interact with underlying heart conditions.
• Recognising early signs of serious reactions (fainting, prolonged erection, allergic reactions, serotonin syndrome).
• Mental health awareness for medicines affecting serotonin pathways, including vigilance for agitation or mood changes.

If you’ve recently been hospitalised for heart problems, have new neurological symptoms, or have changes in your medication list, consult a pharmacist or clinician before taking Tadapox again.
