Sildalis (Sildenafil Citrate 100 mg + Tadalafil 20 mg)

Sildalis (Sildenafil Citrate 100 mg + Tadalafil 20 mg) – Patient Information (UK)

Sildalis contains a combination of two well-known medicines used for erectile dysfunction (ED):

• Sildenafil citrate 100 mg
• Tadalafil 20 mg

This combination is designed to provide erectile support using two different pathways and duration profiles. Below is a patient-friendly overview of what the medicine does, how it works in the body, typical use in adults, key safety information, and practical considerations for daily life in the United Kingdom.

Basic product information

Note: Always follow the instructions provided with your specific product pack and the advice of a qualified healthcare professional.

How Sildalis works (mechanism of action)

Erectile function depends on healthy blood flow to the penis and a normal nerve/hormonal environment. During sexual arousal, nitric oxide is released, which increases levels of cyclic GMP (cGMP) and helps relax smooth muscle in blood vessels.

Sildenafil and tadalafil both work by inhibiting phosphodiesterase (PDE) enzymes involved in this pathway:

• Sildenafil inhibits PDE-5. This supports the nitric oxide–cGMP pathway in the penis, helping blood flow when you are sexually stimulated.
• Tadalafil inhibits PDE-5 as well, but has different pharmacokinetic properties (notably a longer duration of action for many people).

Key point: These medicines do not automatically produce an erection. They help the normal erection process by improving blood flow in response to sexual stimulation.

Pharmacokinetics (how the body absorbs and processes it)

Because Sildalis combines two PDE-5 inhibitors, you may experience effects that begin at different times and last for varying lengths.

Sildenafil (citrate) – overview

• Onset: Often begins working within about 30–60 minutes for many men.
• Duration: Commonly lasts around 4–6 hours (individual responses vary).
• Metabolism: Processed mainly by liver enzymes (CYP pathways) and eliminated through the body.

Tadalafil – overview

• Onset: Often begins working within about 30–120 minutes depending on the person and conditions.
• Duration: Frequently lasts longer, commonly up to 24–36 hours for many people.
• Metabolism: Broken down largely by the liver and eliminated from the body.

Absorption and variability: Both medicines are affected by factors such as food, alcohol, other medications, liver function, and individual metabolism. If you have liver or kidney problems, the ideal dosing schedule may differ.

What Sildalis is used for (indications)

Sildalis is used to treat erectile dysfunction (ED), which means difficulty achieving and/or maintaining an erection sufficient for satisfactory sexual activity.

ED can have physical causes (e.g., blood vessel disease, diabetes, smoking) and/or psychological contributors (stress, anxiety). These medicines address the blood-flow component but do not treat all underlying causes.

Typical use and timing

Sildalis is generally taken as needed before sexual activity. Because it combines two medicines, many people find it useful for planned occasions that may run longer.

• Typical pre-sex timing: Consider taking it approximately 30–60 minutes before sexual activity, but adjust based on how your body responds.
• Flexibility: With tadalafil, the “window” may extend significantly beyond sildenafil alone.

Important: Sexual stimulation is still required. Avoid using it more frequently than recommended.

Dosing information (general guidance)

Always follow the specific instructions given with your product and medical advice. The combination strength in this product is fixed (Sildenafil 100 mg + Tadalafil 20 mg), and this is not a one-size-fits-all approach.

General considerations:

• This combination is typically intended for adults with ED who have been assessed as suitable for PDE-5 inhibitor treatment.
• Lower doses are often used in clinical practice for many men, particularly those who are older, have certain health conditions, or take interacting medications.
• If you are uncertain about suitability, do not self-adjust—seek advice.

Do not exceed the dosing frequency on the product instructions. Using PDE-5 inhibitors too often can increase the risk of side effects (including headache, dizziness, low blood pressure, and in rare cases, more serious cardiovascular events).

Food interactions

Food can affect absorption, especially for sildenafil.

• High-fat meals: May delay the onset of sildenafil, making it take longer to work.
• Timing with meals: If you want more predictable onset, consider taking it with a light meal or on a relatively empty stomach.
• Tadalafil: Can be less sensitive to meals for some people, but individual response varies.

Practical tip: If a previous dose felt slow, you may need to adjust meal timing rather than increase the dose.

Alcohol and medicine interactions

Alcohol

Alcohol can worsen ED and also increase the chance of side effects.

• Moderate to heavy alcohol may reduce erection quality.
• Alcohol may contribute to dizziness and low blood pressure, especially when combined with PDE-5 inhibitors.
• For safer use, keep alcohol moderate and avoid binge drinking.

Major medicine interactions (very important)

Some medicines can interact strongly with sildenafil/tadalafil—particularly those affecting nitric oxide pathways or liver enzymes.

Do NOT take PDE-5 inhibitors if you use nitrates or “nitric oxide donors.” Combining them can cause a dangerous drop in blood pressure.

Examples (not exhaustive):

• Nitrates such as glyceryl trinitrate (GTN), isosorbide dinitrate/mononitrate
• “Poppers” (amyl nitrite and similar nitrite preparations)

Other caution areas:

• Alpha-blockers (used for prostate symptoms and/or high blood pressure): can increase dizziness/low blood pressure when combined. A healthcare professional may need to adjust timing or doses.
• Strong CYP3A4 inhibitors (may increase PDE-5 inhibitor levels), such as certain antifungals and some antibiotics/antivirals (e.g., ketoconazole, itraconazole, ritonavir, cobicistat-containing regimens). This may increase side effects and require dose adjustment.
• CYP3A4 inducers (may reduce effectiveness), such as some anticonvulsants (e.g., carbamazepine, phenytoin), rifampicin, and some herbal products.
• Other PDE-5 inhibitors: avoid taking additional sildenafil or tadalafil products together.
• Riociguat (for pulmonary hypertension): contraindicated with PDE-5 inhibitors due to blood pressure risks.

If you have a long-term condition, take multiple medicines, or use occasional “over-the-counter” products, check with a healthcare professional or pharmacist before starting Sildalis.

Safety profile and side effects

Most men tolerate PDE-5 inhibitors well, but side effects can occur. The combination includes two PDE-5 inhibitors, so side effects may be more noticeable than with a single-agent approach.

Common side effects

• Headache
• Flushing (warmth/redness)
• Indigestion / stomach discomfort
• Nasal congestion (stuffy nose)
• Dizziness
• Back pain / muscle aches (more typical of tadalafil in many people)
• Mild visual effects (e.g., changes in colour perception—usually temporary)

Less common but serious warnings

• Chest pain or severe shortness of breath (seek urgent medical help)
• Severe dizziness or fainting (possible low blood pressure)
• Sudden vision loss or sudden hearing loss (rare, urgent medical assessment needed)
• Priapism (an erection lasting longer than 4 hours): emergency treatment is required

Seek urgent help immediately if you experience chest pain during sex, fainting, an erection lasting longer than 4 hours, sudden vision/hearing changes, or severe allergic-type reactions.

Who should be extra careful?

You may need extra assessment before using Sildalis if you:

• Have heart disease or are advised to avoid sexual activity
• Have a history of stroke or certain cardiovascular conditions
• Have low blood pressure or are prone to dizziness
• Have severe liver impairment
• Have severe kidney impairment
• Have a blood disorder affecting erections (e.g., sickle cell anaemia) or structural penile problems

Practical tips for effective and safer use

• Plan around your response: If you’re trying for the first time, choose a time when you can be comfortable and relaxed.
• Use sexual stimulation: These medicines help, but arousal is still required.
• Avoid heavy meals if onset matters: A light meal may improve timing.
• Keep alcohol moderate: Too much alcohol can increase dizziness and reduce erection quality.
• Don’t combine PDE-5 inhibitors: Avoid taking sildenafil/tadalafil (or similar) products at the same time.
• Know the “red flags”: Seek urgent care for priapism, chest pain, fainting, or sudden vision/hearing loss.
• Review interactions: Especially nitrates, alpha-blockers, and medicines affecting liver enzymes.

Alternative options (for ED in the UK)

If Sildalis doesn’t suit you, several other approaches may be considered depending on your health and preferences.

Other PDE-5 inhibitors

• Sildenafil alone (shorter duration for many)
• Tadalafil alone (longer duration for many)
• Vardenafil or Avanafil (availability varies by region)

Non-medicine options

• Vacuum erection devices
• Intracavernosal injections (specialist-led)
• Intraurethral therapy (specialist-led)
• Psychosexual support if anxiety/stress is a contributing factor
• Lifestyle measures (stop smoking, reduce excess weight, regular exercise, manage diabetes and blood pressure)

Your best option depends on your medical history, medication list, and the timing/duration you want.

UK market, legal and clinical context

In the United Kingdom, treatments for erectile dysfunction are widely used and are supported by established clinical guidance and prescribing practices. PDE-5 inhibitors are used to treat ED in men who are assessed to be suitable based on cardiovascular risk and other health factors.

Key UK considerations:

• Medicines regulation: Products sold in the UK must comply with relevant medicinal product rules and distribution requirements.
• Quality and safety: Choose reputable suppliers and ensure the product has appropriate labelling and packaging.
• Clinical appropriateness: ED can be a marker for cardiovascular disease; a clinician may assess overall risk.

Recent and ongoing guidance themes (general): healthcare providers typically emphasise careful cardiovascular screening, avoidance of dangerous drug combinations (especially nitrates), and review of interacting medications. Many clinicians also encourage addressing underlying conditions such as diabetes, hypertension, smoking, and mental wellbeing.

FAQ

1) How soon will Sildalis work?

For many men, sildenafil may start helping within 30–60 minutes, while tadalafil may contribute over a broader window beginning around 30–120 minutes. Individual response varies, and the speed of onset can be affected by food, alcohol, and other medicines.

2) How long does it last?

Because it contains both sildenafil and tadalafil, the overall effect may be longer than either alone. Many men experience effects over a period of up to about a day, but the “useful window” varies widely.

3) Can I take it every day?

Some men take PDE-5 inhibitors as needed rather than daily. With a fixed high-strength combination product, dosing schedules must be strictly followed. Always use the dosing instructions supplied with your product and seek advice if you are considering frequent use.

4) What happens if I eat a heavy meal?

A heavy, especially fatty, meal may delay the onset of sildenafil. You may still get benefit, but it could take longer to work. A lighter meal may improve timing.

5) Is it safe to drink alcohol with Sildalis?

Moderate alcohol may be tolerated by some people, but alcohol can worsen ED and increase dizziness/low blood pressure risk. Avoid heavy drinking and be cautious with your first dose.

6) Can I take nitrates for angina at the same time?

No. PDE-5 inhibitors (including sildenafil and tadalafil) must not be combined with nitrates or “poppers” because it can cause dangerous blood pressure drops.

7) Can I take it with other ED tablets?

Do not combine it with other PDE-5 inhibitors. Taking multiple similar medicines can increase the risk of side effects.

8) What if I get a headache or flushing?

These are common side effects. Hydration, a calm environment, and avoiding excessive alcohol may help. If headaches are severe, persistent, or accompanied by worrying symptoms (e.g., chest pain or fainting), seek medical help.

9) What should I do if the erection lasts too long?

If an erection lasts longer than 4 hours (priapism), you need urgent medical care. Do not wait for it to resolve on its own.

10) Is Sildalis suitable for everyone with ED?

No. Men with certain heart conditions, very low blood pressure, severe liver/kidney impairment, or those taking interacting medicines (especially nitrates) may be unsuitable or require special dosing advice.

Final reminder: If you are unsure about whether Sildalis is appropriate for you—especially if you take medicines for blood pressure, prostate symptoms, angina, or pulmonary hypertension—speak to a healthcare professional before use.
