What Is Erectile Dysfunction?
Erectile dysfunction (ED) is the persistent inability to get and/or keep an erection firm enough for satisfactory sexual activity. It can be caused by physical factors (such as cardiovascular disease, diabetes, high blood pressure, high cholesterol, or hormonal issues), psychological factors (stress, anxiety), or a combination of both.
ED is common, especially with age, but it may also be an early sign of underlying health conditions that are worth checking. If ED is new, worsening, or occurs alongside chest pain or breathlessness, you should seek medical advice.
Mechanism of Action (How Fildena Extra Power Works)
Sildenafil belongs to a group of medicines called PDE5 inhibitors (phosphodiesterase type 5 inhibitors). When you’re sexually stimulated, natural signals increase nitric oxide in the body. This helps relax smooth muscle and increases blood flow to the penis.
Sildenafil works by blocking PDE5, an enzyme that breaks down a chemical messenger called cGMP. By inhibiting PDE5, sildenafil helps maintain cGMP levels, supporting erection by improving blood flow to the penis.
Important: Sildenafil does not automatically cause an erection. It helps the erection process happen more effectively in response to sexual stimulation.
Pharmacokinetics (Absorption, Onset, Duration)
Absorption and onset
After swallowing, sildenafil is absorbed into the bloodstream. Typical time to onset is often around 30–60 minutes, though it can vary depending on dose and individual factors.
Effect of food
A heavy or fatty meal can delay absorption and reduce the speed of onset. The medicine may still work, but you may notice it takes longer to start.
Duration of action
For many men, effects can last for several hours. Some people report benefit closer to the lower end of that range, while others may find it works longer.
Metabolism and elimination (in simple terms)
Sildenafil is metabolised by the liver (primarily through CYP pathways) and eliminated mostly via the body’s normal waste processes. Because of this, liver impairment and certain drug interactions may change how sildenafil is handled in your body.
Typical Use and Timing
Fildena Extra Power is taken as needed for erectile dysfunction. The goal is to take it at a time that allows it to reach peak levels when you plan to have sex.
When to take it
- Take it about 30–60 minutes before sexual activity, if possible.
- If you’ve eaten a large or high-fat meal, allow more time (the medicine may take longer to work).
- Don’t take it more frequently than recommended.
What to expect
- You may notice improved ability to achieve an erection with sexual stimulation.
- The first experience may require a little “timing adjustment” based on your routine, meal timing, and response.
- If it doesn’t seem to work, it may be due to dose, timing, alcohol/food effects, stress, or underlying medical factors.
Indications (What It Is Used For)
Fildena Extra Power is indicated for the treatment of erectile dysfunction in men. It is used to improve erection quality in response to sexual stimulation.
If you have other conditions (such as heart disease) or you’re taking medicines that affect blood pressure, you should take extra care and follow dosing guidance carefully.
Dosing (Typical Adult Instructions)
The exact strength of “Extra Power” products may differ by formulation. Follow the dose printed on your pack or the guidance from your pharmacist. Below are common sildenafil dosing principles for ED.
General dosing principles
- Start low if you are new to sildenafil or have risk factors (e.g., older age, liver impairment, or interacting medicines).
- Allow time for effect before increasing or changing the dose.
- Maximum frequency: Do not take more often than recommended on the pack (commonly no more than once daily for ED).
If you miss a dose
If you plan to take sildenafil for sexual activity and you miss timing, take it only if it still fits your schedule and remains within the recommended dosing frequency. Do not take extra doses to “catch up.”
Dose adjustments in special situations
Some situations require caution and possibly lower starting doses, including:
- Older age
- Liver impairment
- Use of certain interacting medicines (see below)
- Some cardiovascular conditions—particularly those associated with low blood pressure or use of nitrates
If you are unsure which dose is appropriate, consult a healthcare professional or pharmacist before continuing.
Food Interactions (Including High-Fat Meals)
Food can influence how quickly sildenafil begins working.
- Large, fatty meals may delay onset by slowing absorption.
- A lighter meal may help sildenafil start working closer to your expected timing.
- Alcohol can compound the effect (see “Alcohol and medicine interactions”).
Tip: If you’re planning to use sildenafil, consider a lighter meal earlier in the evening and schedule the dose with adequate time before sex.
Alcohol and Medicine Interactions
Alcohol
Alcohol affects sexual performance and blood circulation. Drinking too much may:
- Make it harder to achieve or maintain an erection
- Increase dizziness and the risk of low blood pressure
- Worsen side effects such as headache, flushing, or nausea
Moderate alcohol is less likely to cause problems, but many men find that limiting alcohol improves reliability. Avoid excessive drinking, especially if you already feel light-headed.
Do not take sildenafil with nitrates
The most important interaction is with medicines containing nitrates (often used for angina/chest pain). Sildenafil can enhance the blood-pressure-lowering effects of nitrates, which may cause dangerous hypotension.
Examples of nitrates include (not exhaustive): glyceryl trinitrate (nitroglycerin), isosorbide dinitrate, and some nitrate-containing preparations.
Other common interaction categories
Tell your pharmacist about all medicines you take, including over-the-counter products and herbal remedies. Sildenafil may interact with:
- Alpha-blockers (e.g., for prostate symptoms or high blood pressure): may increase risk of low blood pressure, especially when starting or adjusting doses.
- Medicines that affect liver enzymes (CYP3A4 inhibitors or inducers): may raise or lower sildenafil levels. Strong inhibitors can increase side effects and require dose adjustments.
- Other ED medicines: combining ED therapies can increase side effects and is usually not advised without professional guidance.
- Blood pressure medicines: sildenafil may further lower blood pressure in some people.
How to reduce interaction risk
- Make a list of all medicines you take (including inhalers, heart medicines, and supplements).
- Check with a pharmacist if you’re unsure about nitrates or blood pressure medicines.
- Do not start or stop prescription medicines solely to “make sildenafil work” without advice.
Safety Profile (Common and Serious Side Effects)
Common side effects
Many people tolerate sildenafil well. Common side effects can include:
- Headache
- Flushing (warmth/redness of the face)
- Indigestion or nausea
- Nasal congestion (stuffy nose)
- Dizziness
- Visual changes (e.g., mild colour tinge or blurred vision in some people)
Serious side effects – seek urgent help
Contact urgent medical services immediately or seek emergency care if you experience:
- Chest pain, severe shortness of breath, or fainting
-
Priapism (an erection lasting 4 hours or more
- Sudden vision loss or severe eye pain
- Sudden hearing loss (sometimes with dizziness)
- Signs of a severe allergic reaction: swelling of the face/lips, breathing difficulty, or widespread rash
Who should be extra cautious?
- People with severe cardiovascular conditions or unstable angina
- Those with very low blood pressure or significant heart rhythm problems
- People who have had stroke or serious heart events recently
- Those taking medicines that interact strongly (especially nitrates and certain blood pressure medicines)
If you have any cardiovascular concerns, get advice before using sildenafil.
Practical Use Tips (For Better Results)
- Plan your timing: Aim for 30–60 minutes before sex (or longer after a heavy meal).
- Keep alcohol moderate: Too much alcohol can reduce performance and increase side effects.
- Focus on stimulation: Sildenafil works with sexual stimulation—don’t rely on the tablet alone.
- Stay hydrated: Dehydration can worsen dizziness and headaches.
- Manage stress: Anxiety about performance is common and can reduce response even when medicine works.
- Try consistently: If you didn’t respond the first time, consider timing/food/alcohol factors before giving up.
- Avoid mixing with other ED treatments unless advised by a healthcare professional.
If sildenafil seems ineffective, it may reflect dose mismatch, timing, drug interactions, or underlying conditions such as diabetes or vascular disease. Consider speaking with a clinician to identify causes and the best treatment approach.
Alternative Options
Sildenafil is one of several approaches for ED. Depending on your health profile and preference, options may include:
Other PDE5 inhibitors
- Tadalafil (often longer lasting for some people)
- Vardenafil
- Avanafil
Non-medicine options
- Lifestyle changes (exercise, weight management, stopping smoking, reducing alcohol)
- Managing underlying conditions (diabetes, high blood pressure, cholesterol)
- Psychosexual support if stress, anxiety, or relationship factors contribute
- Devices such as vacuum erection devices (for selected patients)
Prescription-only treatments (where appropriate)
Some treatments require specialist assessment, such as injectable therapies or other medical options. A healthcare professional can advise which option is most suitable for your situation.
UK Market and Legal Context (Patient-Friendly Overview)
