Malegra (Sildenafil Citrate) – Patient Information

Malegra is a medicine used to treat erectile dysfunction (ED) in adult men. The active ingredient is sildenafil citrate, a well-known treatment that helps you achieve and maintain an erection when you are sexually stimulated.

This page explains how Malegra works, typical uses, timing, food and alcohol interactions, safety information, and practical guidance for getting the most benefit while minimising risk. It is written for people in the United Kingdom.

Quick product overview

How Malegra works (mechanism of action)

Sildenafil belongs to a group of medicines called PDE5 inhibitors. During sexual stimulation, the body increases blood flow to the penis through a natural chemical pathway. One key step involves a molecule called cGMP (cyclic guanosine monophosphate).

PDE5 is an enzyme that breaks down cGMP. By blocking PDE5, sildenafil helps maintain cGMP levels, which supports greater blood flow to the erectile tissue. The result is an improved ability to achieve and maintain an erection during sexual activity.

Important: Malegra does not create sexual desire. It works only in response to sexual stimulation.

Pharmacokinetics (how the body handles it)

Understanding how Malegra is absorbed and processed may help you time your dose effectively.

• Absorption: Sildenafil is absorbed after oral administration. Peak levels typically occur in about 1 to 2 hours.
• Onset: Some people notice effects in roughly 30 to 60 minutes, though it varies by individual and dose.
• Duration: The effect often lasts for around 4 hours, with many people able to achieve erections throughout this window. Some may find the benefit extends longer.
• Metabolism: The liver breaks down sildenafil, mainly via CYP3A4 pathways.
• Elimination: The medicine and its metabolites are cleared primarily through the faeces and urine.

Variability: Timing and intensity can differ depending on factors such as age, liver and kidney function, other medicines, alcohol intake, and whether food delays absorption.

What Malegra is typically used for (indications)

Malegra is indicated for the treatment of erectile dysfunction, meaning difficulty achieving or maintaining an erection sufficient for satisfactory sexual performance.

It may be suitable when ED is associated with a range of causes, including stress, blood flow changes, diabetes, and other conditions—however, suitability depends on your medical history and other medications.

Typical dosing and how to take Malegra

Dosage can vary between individuals. The following guidance is general information and reflects common practice for sildenafil medicines. Your clinician or pharmacist may adjust dosing to suit you.

Typical starting dose (common approach)

• Most adults: 50 mg taken as needed, about 1 hour before sexual activity.
• Some people may start lower: 25 mg may be used if you are older, have certain medical conditions, or are taking medicines that may increase sildenafil levels.

How often to take it

• Do not take more than one dose in 24 hours.

Adjusting the dose

• If the effect is too weak, your dose may be increased (for example, to 100 mg) depending on safety and tolerability.
• If side effects occur, dose reduction may be considered.

How to take

• Take the tablet with water.
• Plan to take it when you can allow time for it to work.
• Ensure you are sexually stimulated; sildenafil supports erections but does not replace arousal.

Timing: when will Malegra work?

For many men, sildenafil works best when taken shortly before sex.

• Typical timing: about 1 hour before sexual activity.
• Possible earlier onset: some people notice effects between 30–60 minutes.
• Food can delay onset: see the food section below.

Practical tip: Avoid taking it “right before” if you’re planning an evening meal or if you usually eat heavy meals—food may delay absorption.

Food interactions

Food can affect how quickly sildenafil is absorbed.

• Heavy or high-fat meals: may slow absorption and delay onset, meaning it may take longer to work.
• Light meals: may have less impact, and some people still experience good effects if they take sildenafil after a lighter snack.

If you notice your usual timing doesn’t work, consider whether meals may be delaying the effect and trial a slightly earlier dose next time (within safe limits).

Alcohol and Malegra

Alcohol can influence erectile function in two ways: it may reduce arousal and it can affect blood vessels. Together with sildenafil, this may increase the chance of dizziness or low blood pressure.

• Moderate alcohol: may be tolerated by some men, but performance may still be reduced.
• Heavy drinking: can worsen ED and may increase side effects such as dizziness, headache, and flushing.

Safety note: If you feel light-headed, unwell, or your vision changes, avoid driving and do not take additional alcohol. Seek medical help urgently if you develop chest pain, fainting, or severe shortness of breath.

Medicine interactions (including vital warnings)

Interactions are important for safety. Certain medicines can significantly increase sildenafil levels or cause dangerous blood pressure changes.

Absolute warning: nitrates and “nitric oxide donors”

Do not use Malegra if you take nitrate medicines for chest pain (angina) or “nitric oxide donors” (for example, glyceryl trinitrate). The combination can cause a dangerous drop in blood pressure.

• Examples include medicines used for angina and some severe heart conditions.
• If chest pain occurs after taking sildenafil, seek urgent medical attention and tell healthcare professionals that you have used a PDE5 inhibitor.

Alpha-blockers (for prostate or blood pressure)

Men taking alpha-blockers (such as tamsulosin, doxazosin, or similar medicines) may be more prone to dizziness or low blood pressure, especially during dose initiation.

• Tell a clinician or pharmacist if you take an alpha-blocker.
• Often, a lower starting dose of sildenafil is used and timing may be adjusted.

Medicines that increase sildenafil levels (CYP3A4 inhibitors)

Some drugs can raise sildenafil concentrations, increasing both effectiveness and the risk of side effects. Examples include:

• Some antifungal medicines (e.g., ketoconazole, itraconazole)
• Some antibiotics (e.g., clarithromycin)
• Medicines used to treat HIV (antiretroviral therapies)
• Some medicines for certain heart rhythm conditions

If you take medicines from this group, your dose may need to be reduced and you may be advised to take it with extra caution.

Medicines that decrease sildenafil levels

Some medicines may reduce sildenafil levels, potentially making it less effective. Examples include:

• Rifampicin (antibiotic used for tuberculosis)
• Some anticonvulsants
• Other strong enzyme-inducing medicines

Other ED treatments

Do not combine sildenafil with other PDE5 inhibitors (such as tadalafil or vardenafil). Using multiple PDE5 inhibitors together can increase the risk of side effects and does not necessarily improve outcomes.

Riociguat

Do not take sildenafil with riociguat (used for certain types of pulmonary hypertension). This combination may also cause unsafe blood pressure effects.

Safety profile: side effects and when to seek help

Like all medicines, Malegra can cause side effects. Many are mild and temporary.

Common side effects

• Headache
• Flushing (warmth or redness)
• Indigestion or nausea
• Stuffy or runny nose
• Dizziness
• Blurred vision or changes in colour perception (often described as a bluish tinge)

Less common but important

• Temporary effects on hearing or ringing in ears (seek advice if this occurs)
• Prolonged erection (priapism): an erection lasting longer than 4 hours
• Allergic reactions: rash, swelling of face/lips, breathing difficulty

Seek urgent medical help if you experience

• Chest pain or symptoms of a heart problem
• Fainting or severe dizziness
• Sudden vision loss or severe eye pain
• Sudden hearing loss
• Pripaism (erection lasting more than 4 hours)

Always tell emergency or medical staff that you have taken sildenafil.

Who should be extra cautious?

• Men with known heart disease, unstable angina, recent heart attack or stroke
• People with very low blood pressure or conditions causing blood pressure instability
• Those with severe liver impairment
• Those with severe kidney impairment (dose adjustments may be needed)
• Men taking multiple medicines that affect blood pressure or heart rhythm

Practical use tips for better results

• Start with the right timing: plan for roughly an hour before sex.
• Consider meal size: a heavy meal can delay onset; try a lighter meal if timing feels inconsistent.
• Be careful with alcohol: limit drinking and avoid excessive amounts.
• Follow the 24-hour rule: do not take more than one dose per day.
• Give it a fair trial: if it feels ineffective, it may relate to timing, dose, or underlying health factors—discuss adjustments with a clinician or pharmacist.
• Manage contributing factors: lifestyle changes (stopping smoking, reducing excess weight, exercise, and controlling diabetes) can improve ED long-term.

Alternative options to Malegra

If sildenafil isn’t suitable or isn’t working well, there are other treatment options for ED. Options may include:

Other PDE5 inhibitors

• Tadalafil – longer duration for some men
• Vardenafil – similar class, different timing for onset in some individuals

Non-PDE5 approaches

• Vacuum erection devices
• Intraurethral or injectable therapies (specialist use)
• Psychosexual support if performance anxiety or relationship factors contribute
• Addressing underlying health issues such as diabetes, hypertension, or high cholesterol

Note: Each option has its own suitability and interaction profile. A clinician can help you choose the safest approach based on your health and medication list.
