MaxGun Sublingual Spray (Sildenafil Oral Spray) — Patient-Friendly Guide

MaxGun Sublingual Spray contains sildenafil, a medicine used to treat erectile dysfunction (ED). It is provided as an oral spray designed to be used in the mouth, with absorption through the oral tissues. This guide explains how the medicine works, when and how to use it, important safety information, and practical tips for Australians.

Always read the Consumer Medicine Information (CMI) supplied with your product and follow the instructions from your healthcare professional or pharmacist.

Basic product information

• Medicine name: MaxGun Sublingual Spray
• Active ingredient: Sildenafil
• Dosage form: Sublingual/oral spray (sildenafil oral spray)
• Common purpose: Treatment of erectile dysfunction
• How it works: Increases blood flow to the penis to help achieve and maintain an erection during sexual stimulation

Strengths: MaxGun products may come in different strengths depending on the packaging (for example, the number of sprays per dose or the sildenafil concentration). Check the label/box for the exact strength and the number of actuations per dose.

How sildenafil works (mechanism of action)

Sildenafil is a PDE5 (phosphodiesterase type 5) inhibitor. It works by:

• Blocking PDE5, an enzyme that normally breaks down cGMP (cyclic guanosine monophosphate).
• Allowing cGMP levels to rise, which helps smooth muscle cells relax in blood vessels.
• Increasing blood flow to the erectile tissue in the penis, which supports erections when you are sexually aroused.

Important: Sildenafil does not automatically produce an erection. Sexual stimulation is still required.

Pharmacokinetics (absorption, onset, and duration)

Because MaxGun is an oral spray intended for absorption through the mouth, the onset can be relatively quicker than some traditional oral tablets for certain people. Individual response varies.

General pharmacokinetic features of sildenafil

• Absorption: Sildenafil is absorbed after administration via the oral mucosa and/or gastrointestinal tract.
• Peak effect: Peak blood levels typically occur within about 30 minutes to 1 hour after dosing with oral formulations (exact time may vary).
• Duration: Effects may last for several hours, allowing time for sexual activity. Many people experience benefit for up to about 4 hours, though some may notice longer or shorter responsiveness.
• Metabolism: Sildenafil is mainly metabolised by the liver (primarily CYP3A4).
• Elimination: Mostly eliminated through faeces and urine metabolites.

Practical takeaway: Plan your dose based on when you want to be sexually active, while recognising that response may differ depending on food intake, alcohol, and other medicines.

What it’s used for (indications)

MaxGun Sublingual Spray is used to treat erectile dysfunction (ED) in adult men, including men who have difficulty achieving or maintaining an erection sufficient for satisfactory sexual performance.

It is not indicated for improving libido (sex drive) and it does not protect against sexually transmitted infections (STIs).

Typical timing and how to use it

Correct timing can improve the chance of a successful outcome.

When to take MaxGun

• For many people, sildenafil works best when taken approximately 30 minutes to 1 hour before sexual activity.
• You may still be able to be sexually active within a few hours after dosing, depending on individual response.

How to use the spray (general guidance)

Follow your product label instructions exactly. In general, the goal is to deliver the dose into the mouth for oral mucosal absorption.

• Step 1: Check the prescribed dose and confirm the number of sprays/actuations.
• Step 2: Keep the mouth slightly open. Aim the spray toward the inner cheek or under the tongue area, as directed by the CMI or packaging.
• Step 3: Avoid swallowing immediately if your instructions advise not to. Let the spray sit in the mouth briefly.
• Step 4: Replace the cap and store safely.
• Step 5: Wash hands after use.

Tip: If you are uncertain about your specific dosing technique, ask your pharmacist to show you how to use the spray device correctly.

Dosing (adults)

Dose strength and frequency can vary. Use only the dose stated on your product information or as advised by your healthcare professional.

Typical dosing principles for sildenafil in ED

• Start low: Many people begin with a lower strength to assess tolerance and response.
• Maximum frequency: ED dosing is typically limited to a maximum of once daily for sildenafil-containing products.
• Adjustments: Some factors (such as age, liver/kidney function, and interacting medicines) may require dose adjustment.

Do not take additional doses within the same day to “increase effect” if the first dose is ineffective. If you’re not getting the desired result, speak with a pharmacist or doctor for assessment of dose suitability and interacting factors.

Food interactions

Food—especially high-fat meals—can reduce or delay sildenafil absorption for some people, potentially making the onset slower.

• High-fat meals: May delay the onset and reduce effectiveness for a period after eating.
• Timing strategy: If you experience reduced effect, consider taking the dose when you are not immediately after a heavy, fatty meal.

Note: Because MaxGun is a spray formulation, some people may notice less effect from food than with certain tablets, but food can still matter.

Alcohol interactions

Alcohol can contribute to erectile dysfunction and may worsen side effects such as dizziness or low blood pressure.

• Moderate to heavy drinking: May reduce the ability to achieve or maintain an erection.
• Increased dizziness/light-headedness: When combined with sildenafil, you may feel more unsteady.

Practical approach: If you plan to drink, keep alcohol moderate and allow time to gauge your response. Avoid driving or operating machinery if you feel dizzy.

Medicine interactions (very important)

Sildenafil can interact with several medicines, some of which may cause dangerous drops in blood pressure or other serious side effects.

Absolute/major caution: nitrates and “NO donors”

• Do not use sildenafil with nitrates (e.g., glyceryl trinitrate/GTN) or other medicines that release nitric oxide.
• The combination can cause significant hypotension (dangerously low blood pressure).

Other important interactions

• Alpha-blockers (for prostate symptoms or hypertension): may increase risk of low blood pressure, particularly when initiating sildenafil or when dosing changes.
• Riociguat: combination may increase risk of low blood pressure and is generally contraindicated.
• Strong CYP3A4 inhibitors (e.g., some antifungals/antivirals such as ketoconazole/ritonavir): can raise sildenafil levels, increasing side effects risk.
• Some antibiotics/antifungals and cimetidine: may affect sildenafil metabolism.
• Other ED treatments or pulmonary hypertension medicines: combining PDE5 inhibitors may increase adverse effects and is not recommended without medical guidance.

Safety checklist before using

Tell your pharmacist or doctor if you take any of the following (or anything similar):

• Nitrates (for angina/heart pain) or “GTN” sprays/tablets
• Riociguat
• Alpha-blockers (e.g., tamsulosin, doxazosin, alfuzosin)
• Blood pressure medicines
• HIV medicines or antifungals
• Any recreational “poppers” containing nitrates
• Other PDE5 inhibitors

Seek urgent help if you develop symptoms such as severe dizziness, fainting, chest pain, or signs of an allergic reaction.

Indications and suitability (who should be cautious)

MaxGun is for adult men with ED, but some conditions require extra caution.

Use with caution or talk to a clinician if you have:

• Severe heart problems or unstable angina
• Recent stroke or heart attack (timing guidance is individual)
• Significant liver disease
• Severe kidney impairment
• Very low blood pressure
• Retinal conditions or a history of non-arteritic anterior ischaemic optic neuropathy (NAION)
• Bleeding disorders or conditions predisposing to priapism

ED can sometimes be a marker of underlying cardiovascular disease. If ED is new or worsening, consider discussing it with a healthcare professional.

Safety profile and side effects

Like all medicines, sildenafil can cause side effects. Not everyone gets them, and many are mild and short-lived.

Common side effects

• Headache
• Flushing (warmth/redness)
• Dizziness
• Indigestion or stomach discomfort
• Nasal congestion
• Visual disturbances (e.g., mild blurring or increased light sensitivity)

Less common but serious — get urgent medical help

• Chest pain or symptoms suggesting a heart problem
• Fainting or severe dizziness
• Sudden vision loss or sudden hearing changes
• Prolonged erection lasting more than 4 hours (priapism)
• Severe allergic reaction (swelling of face/lips, difficulty breathing)

Emergency tip: If you suspect priapism, seek urgent care immediately. Delaying treatment can cause permanent damage.

Practical use tips for better results

• Use at the right time: Start with dosing about 30 minutes to 1 hour before sex.
• Consider meal timing: Avoid heavy, fatty meals right before dosing if you notice delayed or reduced effects.
• Limit alcohol: Keep alcohol moderate to support erection quality.
• Give it a fair trial: Some men need more than one attempt to find the best timing and dose within safe limits.
• Be consistent: Stress, fatigue, and anxiety can significantly impact ED. A calm environment and adequate foreplay may improve outcomes.
• Don’t combine with similar medicines: Avoid taking other ED treatments at the same time.
• Check for interacting medicines: Many “hidden” interactions come from heart medicines and some antifungals/antivirals.

Alternative options (if sildenafil spray isn’t suitable)

ED has multiple treatment pathways. Depending on your medical situation and preferences, alternatives may include:

• Other sildenafil formulations: Sildenafil tablets may differ in onset and food effects.
• Tadalafil: Another PDE5 inhibitor, often with a longer duration of action for some people.
• Vardenafil or avanafil: Other PDE5 inhibitor options with different onset profiles.
• Non-drug options: Vacuum erection devices, lifestyle changes, counselling/sex therapy, and addressing contributing factors such as diabetes or cardiovascular risk.
• Hormone assessment: If low testosterone or endocrine issues are suspected, testing may be discussed with a clinician.

When to seek medical advice: If ED persists despite appropriate use, or if ED is associated with chest pain, shortness of breath, or other cardiovascular symptoms, consult a healthcare professional.
