What is Fildena Extra Power?
Fildena Extra Power is an oral medicine used for ED. ED is the consistent or frequent inability to get and/or keep an erection sufficient for satisfactory sexual performance. Sildenafil helps improve erectile function by targeting the pathways involved in blood vessel relaxation.
Like other sildenafil-containing medicines, Fildena Extra Power does not automatically cause an erection. Instead, it enhances the natural erectile response to sexual stimulation.
How it works (mechanism of action)
Sildenafil belongs to a group of medicines called phosphodiesterase type 5 (PDE5) inhibitors. During sexual stimulation, nitric oxide (NO) is released, which triggers the production of cyclic guanosine monophosphate (cGMP). cGMP helps relax smooth muscle in the penis and allows increased blood flow.
PDE5 normally breaks down cGMP. Sildenafil inhibits PDE5, helping cGMP levels remain higher for longer. The result is improved blood flow during sexual stimulation, supporting erections.
- Improves erection quality by enhancing blood flow
- Requires sexual stimulation to work effectively
- Does not increase libido directly
Pharmacokinetics: how the body processes sildenafil
Understanding how sildenafil behaves in the body can help you use it more effectively and safely. Pharmacokinetics describes absorption, distribution, metabolism, and elimination.
Absorption
Sildenafil is absorbed after oral administration and reaches peak levels in the bloodstream at around 30 to 120 minutes in many people. Timing can vary depending on dose, individual metabolism, and whether you have eaten.
Distribution
Sildenafil is bound to plasma proteins. It distributes throughout the body, including to tissues involved in erectile function.
Metabolism
Sildenafil is mainly metabolised by liver enzymes, particularly the CYP3A4 pathway. This is important because some medicines can increase or decrease its levels.
Elimination
Sildenafil and its metabolites are excreted primarily via the faeces and urine. The “effective” duration can differ from how long it stays detectable in the body.
Typical use and indications
Fildena Extra Power is intended for the treatment of erectile dysfunction in adult men. It may be used when ED affects sexual activity, self-confidence, or relationship wellbeing.
It may be appropriate if you have ED due to a variety of causes such as:
- Age-related changes
- Stress, performance anxiety, or psychological factors
- Some medical conditions that affect blood flow (as advised by a clinician)
- Conditions where impaired blood vessel relaxation contributes to ED
If you have ED as a result of an underlying health problem (for example, cardiovascular disease, diabetes, or hormonal issues), it’s important to address the root cause with appropriate medical guidance.
Dose and how to take it (UK-friendly practical guidance)
The exact strength of Fildena Extra Power varies by product pack—always check the tablet strength in mg on your packaging. The information below provides general guidance for sildenafil medicines.
Starting dose
Many men start with the lowest effective dose. If you are new to sildenafil or are taking other medicines that may interact, your clinician or pharmacy may recommend a lower dose.
Typical dosing frequency
- Take sildenafil as needed before sexual activity.
- Do not take more than once within 24 hours unless a clinician advises otherwise.
- Use the dose that achieves effect without unnecessary side effects.
Swallowing and administration
Swallow the tablet whole with water. Avoid crushing unless the pack specifically allows it. If you experience stomach upset, taking it with a small snack may help (see “Food interactions” below).
When does it work? (timing)
Timing can make a big difference. Sildenafil is often effective within 30–60 minutes, and some people may need up to around 2 hours for best effect.
Practical timing tips:
- Consider taking it approximately 1 hour before planned sexual activity.
- If you’ve eaten a heavy meal, you may need to allow more time (see food section).
- If it doesn’t seem to work, do not increase the dose repeatedly in a short time—speak to a healthcare professional or pharmacy.
Food interactions
Food can affect how quickly sildenafil is absorbed. A heavy or high-fat meal may delay absorption and delay the onset of effect.
- Smaller, lighter meals may reduce delay.
- If you know you’ll eat a large meal, consider taking sildenafil a little earlier to allow time for absorption.
- Alcohol can also influence performance and side effects (see below).
Mild stomach upset can occur. Staying well hydrated and following recommended timing can help.
Alcohol interactions
Alcohol can worsen ED symptoms by affecting nervous system signals and blood vessel function. It may also increase the likelihood of side effects such as dizziness or light-headedness.
Safety approach:
- Keep alcohol intake moderate.
- Avoid “binge” drinking before taking sildenafil.
- If you feel dizzy or faint, lie down and seek medical advice urgently if symptoms persist.
Sildenafil and alcohol together can sometimes cause changes in blood pressure, especially in susceptible individuals.
Medicine interactions: what to watch for
Some medicines can make sildenafil levels rise or fall, or can be unsafe when combined. Always check interactions with your pharmacist or healthcare provider—especially if you take multiple medicines.
Absolute contraindication: nitrates
Sildenafil must not be used with nitrates (for example, glyceryl trinitrate) or nitrite preparations because the combination can cause a potentially dangerous drop in blood pressure.
This includes certain chest-pain treatments. If you use nitrate medication for angina, seek urgent medical advice on safe ED treatment options.
Riociguat
Sildenafil must not be used with riociguat (used for certain lung/blood pressure conditions) due to similar blood pressure risks.
Alpha-blockers
Men taking alpha-blockers for prostate symptoms or blood pressure may be at risk of dizziness or low blood pressure when sildenafil is combined. Your clinician may adjust dose timing or start with a lower sildenafil dose.
Medicines that can increase sildenafil levels
Drugs that inhibit CYP3A4 may increase sildenafil exposure, raising the chance of side effects. Examples may include some treatments for fungal infections (certain azoles) or HIV medicines (certain protease inhibitors). Your pharmacist can advise based on your specific products.
Medicines that can decrease sildenafil levels
Medicines that induce liver enzymes (for example, some treatments for seizures or certain antibiotics like rifampicin) can reduce sildenafil levels, potentially reducing effectiveness.
Other ED medicines
Do not combine sildenafil with other ED treatments (particularly PDE5 inhibitors) unless explicitly instructed by a healthcare professional.
Safety profile: common side effects and when to seek help
Like all medicines, sildenafil can cause side effects. Many are mild and improve as your body adjusts. However, some reactions require urgent attention.
Common side effects
- Headache
- Flushing (warmth, redness)
- Indigestion or nausea
- Blocked or runny nose
- Back pain or muscle aches (sometimes reported)
- Dizziness
- Visual effects (temporary changes in colour perception or light sensitivity)
Less common but serious concerns
Seek urgent medical advice (or emergency help) if you experience:
- Chest pain, severe shortness of breath, or symptoms suggesting a heart problem
- Fainting or severe dizziness
- An erection lasting longer than 4 hours (priapism)
- Sudden vision loss or severe visual disturbance
- Symptoms of an allergic reaction such as swelling of the face/lips, trouble breathing, or widespread rash
Who should be extra cautious?
You should discuss sildenafil use with a clinician if you have certain heart or circulation conditions, significantly low blood pressure, or a history of certain eye conditions. If you are unsure, ask a pharmacist for a tailored safety check.
Practical use tips for better results
Many people find that improving preparation and managing expectations helps. Consider these practical tips:
- Give it time: try taking it around the recommended time before sex (often ~1 hour).
- Keep meals lighter: a heavy meal may delay onset.
- Use it in a calm setting: stress and anxiety can reduce effectiveness.
- Stay hydrated: dehydration can worsen dizziness.
- Avoid mixing with unsafe medicines: especially nitrates.
- Don’t “stack” doses: only take one dose in 24 hours unless advised otherwise.
- Track what works: note your dose and timing so you can refine your approach.
If sildenafil seems ineffective, it can be due to incorrect timing, food effects, alcohol use, insufficient stimulation, or interactions with other medicines. Speak to a pharmacist or clinician before changing the dose.
Missed dose
Fildena Extra Power is taken as needed. If you miss your planned timing, you can take it later before sexual activity, as long as you still follow the recommended maximum frequency (do not take more than once in 24 hours).
Alternative options for ED
ED is common and treatable. Depending on your health profile, preferences, and response to sildenafil, you may consider alternatives:
Other PDE5 inhibitors
- Tadalafil (often longer lasting)
- Vardenafil
- Avanafil
Non-medicine options
- Lifestyle changes: reduce smoking, manage weight, exercise, improve sleep
- Reduce alcohol and address stress
- Psychosexual counselling if anxiety or relationship factors contribute
- Devices (for example, vacuum erection devices) if suitable
- Other medical treatments such as injections or implants when appropriate
Your clinician can help choose the safest option, particularly if you have cardiovascular disease or take interacting medications.
