Silvitra (Sildenafil Citrate 100 mg + Vardenafil 20 mg) — Patient Information (Australia)

Silvitra is a combination medicine containing sildenafil citrate 100 mg and vardenafil 20 mg. It is used to help men with erectile dysfunction achieve and maintain an erection during sexual activity.

This guide is written to be patient-friendly and practical. It explains how the medicine works, when to take it, what to expect, key safety considerations, and common interactions—especially in an Australian context.

How Silvitra Works (Mechanism of Action)

Silvitra contains two medicines from the PDE-5 inhibitor family: sildenafil and vardenafil.

During sexual stimulation, nitric oxide (NO) is released in the body and helps relax smooth muscle in the penile blood vessels. This relaxation allows more blood to flow into the penis, helping produce and maintain an erection.

PDE-5 is an enzyme that breaks down cGMP, a chemical that supports this blood-vessel relaxation. Sildenafil and vardenafil both block PDE-5, which helps cGMP last longer—so erections can be achieved more effectively when you are sexually aroused.

Important: Silvitra does not automatically create an erection. Sexual stimulation is still required.

Pharmacokinetics (Absorption, Onset, Duration)

“Pharmacokinetics” describes what the body does to a medicine—how quickly it’s absorbed, how long it lasts, and how it’s eliminated. The exact speed and level can vary by individual factors such as age, liver function, and other medicines.

General expectations for PDE-5 inhibitors

Absorption: Both components are absorbed after oral dosing.
Onset: Many men notice effects within about 30–60 minutes (sometimes sooner, depending on food and individual response).
Peak effect: The strongest effect is often reached within a few hours.
Duration: Effects may last for several hours; some men may notice benefit for up to about a full day, though the strength generally decreases with time.

Elimination

PDE-5 inhibitors are mainly cleared by the body through hepatic (liver) metabolism and renal (kidney) elimination. Reduced liver function can increase medicine exposure.

What Silvitra Is Typically Used For (Indications)

Silvitra is used to treat erectile dysfunction (ED)—the persistent difficulty achieving or maintaining an erection sufficient for satisfactory sexual performance.

It may be considered when ED is related to factors such as vascular health, diabetes, stress-related factors, or other common causes. However, ED can also be a sign of underlying cardiovascular disease, so it’s important to discuss symptoms with a healthcare professional if ED is new, worsening, or associated with chest pain or breathlessness.

Before You Use Silvitra — Key Safety Notes

Do not take if any of the following apply

Nitrates (e.g., glyceryl trinitrate/nitroglycerin, isosorbide) used for chest pain or other heart conditions.
Combining nitrates with PDE-5 inhibitors can cause a dangerous drop in blood pressure.
Riociguat (used for pulmonary arterial hypertension).
This combination can also lower blood pressure dangerously.
Severe heart problems or medical conditions where sexual activity is not recommended.
Recent serious eye conditions (such as NAION—non-arteritic anterior ischemic optic neuropathy) if advised by a clinician.

Be cautious / seek medical advice

Low blood pressure or history of fainting
Recent stroke or heart attack
Severe liver impairment
Severe kidney disease
Body anatomy issues (e.g., Peyronie’s disease) or conditions causing prolonged erections
Taking medicines that may interact (see interactions section)

Dosing and How to Take It (Practical Guidance)

Silvitra is taken by mouth prior to sexual activity. The exact dose and frequency should follow the product’s instructions and/or advice from a qualified health professional.

Typical “as needed” timing

Take it about 30–60 minutes before planned sexual activity.
If you notice slower onset (for example, due to food), allow additional time.
Do not take more than once in a 24-hour period (unless specifically advised otherwise by a healthcare professional).

How to improve your results

Ensure you have sexual stimulation—the medicine supports the process, but arousal is required.
Use the medicine consistently for a few attempts (unless side effects occur), as response can vary.
Address contributing factors such as smoking, high blood pressure, diabetes control, stress, and sleep.

Timing Considerations: When It Works Best

The onset and strength of PDE-5 inhibitors are influenced by digestion and overall health. Many people find that effects are most noticeable after a short “window” following a dose.

Typical effective window: around 30 minutes to 4 hours after taking it (individual variation is expected).
Plan ahead: avoid taking it at the last minute if you’ve eaten a heavy meal.
If it doesn’t work: don’t assume the medicine never helps—review timing, food intake, alcohol, and interacting medicines.

Food Interactions (What You Should Know)

Food—especially high-fat meals—can slow down absorption and reduce or delay the effect.

After a heavy/fatty meal: you may need to take Silvitra earlier (e.g., closer to 60–90 minutes before sex) or switch to a lighter meal beforehand.
Fasting or light meals: onset may be quicker and more predictable.

You can still take Silvitra with food if needed, but if you’re aiming for consistent timing, a lighter meal is often helpful.

Alcohol Interactions (Safety and Performance Tips)

Alcohol can affect both erections and safety. In combination with PDE-5 inhibitors, alcohol may:

Increase the chance of dizziness, light-headedness, or low blood pressure
Worsen erectile performance due to effects on the nervous system and blood vessels
Increase fatigue and reduce sexual responsiveness

If you plan to drink, consider:

Limit alcohol (especially avoid heavy drinking)
Rise slowly from sitting/lying down
Avoid drinking more than you would comfortably manage

Medicine Interactions (Important)

PDE-5 inhibitors can interact with other medications. Always review your current medicines (including “natural” products) with a healthcare professional or pharmacist.

Most critical interactions

Nitrates (for chest pain): Do not combine.
Examples may include glyceryl trinitrate/nitroglycerin and isosorbide medicines.
Riociguat: Do not combine.

Blood pressure medicines and other cardiovascular drugs

Alpha-blockers (used for prostate symptoms or high blood pressure) may increase the risk of low blood pressure—medical advice is recommended for safe timing and dosing.
Some antihypertensive medicines can also contribute to dizziness, particularly if you drink alcohol.

Medicines that can raise PDE-5 inhibitor levels

Some drugs inhibit liver enzymes that metabolise PDE-5 inhibitors, potentially increasing exposure and side effects.

Certain antifungal medicines (e.g., ketoconazole, itraconazole)
Certain antibiotics/antivirals (e.g., some macrolides; HIV protease inhibitors)
Some other strong enzyme inhibitors

Medicines that may reduce effectiveness

Some enzyme inducers may reduce blood levels of PDE-5 inhibitors, potentially making them less effective.

Grapefruit/other food-drug effects

Grapefruit and similar products may affect enzyme systems involved in drug metabolism for some PDE-5 inhibitors. If you are prone to interactions, consider avoiding grapefruit.

Always seek advice if you’re unsure about a medicine you take.

Safety Profile: Common and Serious Side Effects

Like all medicines, Silvitra can cause side effects. Many are mild and temporary, but it’s important to know what to watch for.

Common side effects

Headache
Flushing (warmth/redness)
Indigestion or nausea
Dizziness
Stuffed nose
Back pain or muscle aches (can occur with PDE-5 inhibitors)
Visual changes (e.g., blurred vision or sensitivity to light)

Less common but important warning signs (seek urgent care)

Chest pain or symptoms of a serious heart problem
Fainting or severe dizziness
Prolonged erection (priapism), lasting 4 hours or more
Sudden vision loss or sudden severe decrease in vision
Sudden hearing loss or severe ringing in the ears

If any of these occur, stop taking the medicine and seek emergency medical help.

Practical Use Tips (What Helps Most People)

Choose the right moment: take the dose at the planned time before sex, considering meal timing.
Stay hydrated and avoid overheating.
Manage stress and performance anxiety—these strongly influence ED.
Be realistic about expectations: erections require arousal; the medicine supports the process.
Don’t “stack” doses: taking extra doses increases side effects without guaranteeing better results.
Track what worked: note timing, food, alcohol, and side effects to improve future attempts.

Alternative Options for Erectile Dysfunction

If Silvitra isn’t suitable, there are multiple alternatives depending on your health, preferences, and cause of ED.

Other oral PDE-5 inhibitor medicines

Sildenafil (often known by brand names such as Viagra)
Tadalafil (longer acting in many people)
Vardenafil (another PDE-5 inhibitor)
Avanafil (rapid onset in some cases)

Other ED approaches

Lifestyle measures: exercise, weight management, smoking cessation, reduced alcohol, and sleep optimisation
Managing underlying conditions: blood sugar control, blood pressure treatment, and reviewing medications that may cause ED
Vacuum erection devices (mechanical support)
Penile injections or suppositories (where appropriate under medical supervision)
Psychosexual support if anxiety or relationship factors contribute

A clinician can help determine the safest option based on your heart health, medications, and previous response.
