Genegra (Viagra Strips) – Patient Information (Australia)

Genegra is a brand of sildenafil in an easy-to-use strip format. It is designed for men who have difficulty achieving or maintaining an erection that is firm enough for sexual activity. This page explains how Genegra works, how to take it, key safety information, and what to consider regarding food, alcohol, and other medicines.

The information below is intended to help you understand Genegra better. It does not replace advice from a healthcare professional. If you have any concerns—especially about heart health, blood pressure, or medication interactions—seek medical guidance.

Quick facts

• Active ingredient: Sildenafil (the same active ingredient as Viagra)
• Dosage form: Oral “strip” (placed on the tongue to dissolve)
• Common use: Erectile dysfunction (ED)
• How it works: Helps improve blood flow to the penis during sexual stimulation
• Typical onset: Often within 30–60 minutes
• Duration: Effects may last several hours (commonly up to ~4 hours or more)

Basic product information

Exact strip strength can vary by product presentation. Please confirm the dose printed on your specific Genegra strip pack.

How Genegra works (mechanism of action)

Genegra contains sildenafil, a medicine in the class called PDE5 inhibitors (phosphodiesterase type 5 inhibitors).

During sexual arousal, nitric oxide is released in the penis, which increases levels of cGMP. cGMP relaxes smooth muscle and allows increased blood flow to help achieve an erection.

PDE5 is an enzyme that breaks down cGMP. Sildenafil works by inhibiting PDE5, which helps maintain cGMP levels longer. As a result, blood vessels can relax more effectively when you are sexually stimulated, improving your ability to get and keep an erection.

• Not an aphrodisiac: Genegra does not automatically create sexual desire.
• Works with arousal: It supports the normal response to sexual stimulation.

Pharmacokinetics (how the body handles sildenafil)

Pharmacokinetics describe how the medicine is absorbed, distributed, metabolised, and eliminated. While exact values can vary between individuals, the following patterns are common for sildenafil:

• Absorption: Sildenafil is absorbed after oral administration. With the strip format, the strip dissolves in the mouth and the medication is swallowed/absorbed through the oral route.
• Time to peak effect: Blood levels typically peak within about 30–120 minutes after dosing.
• Metabolism: Primarily metabolised by the liver enzyme system, mainly CYP3A4 (and related pathways).
• Elimination: Metabolites are removed mainly via the liver and kidneys.
• Duration: While effects vary, many men notice benefits for several hours; clinically, sildenafil is often considered to have a window of effectiveness of up to ~4 hours or longer for some individuals.

Because sildenafil metabolism relies on liver enzymes, certain medicines (and some foods/supplements) can change how fast sildenafil is processed.

Typical use and timing

When to take Genegra

Genegra is taken before sexual activity. The aim is to have the medicine reach effective levels when you are ready.

• Common timing: Take about 30 to 60 minutes before sex.
• Consider individual response: Some men may feel effects sooner; others may take longer.
• Consistency matters: Your first dose may help you learn the best timing for your body.

How to use the strip

• Open the sachet/pack according to the instructions on the label.
• Place the strip on the tongue and allow it to dissolve.
• Avoid chewing the strip.
• Follow the directions provided with your specific product.

If you miss a planned time for sex, you can generally take it later if needed—within reasonable timing for effect. However, do not take more frequently than recommended.

Indications (what Genegra is used for)

Genegra is used for erectile dysfunction (ED)—the persistent difficulty achieving and/or maintaining an erection sufficient for satisfactory sexual performance.

It is intended for adult men. If you have other causes of sexual difficulty (such as hormonal issues, severe depression, medication side effects, or nerve/vascular problems), these should also be assessed.

Dosing (general guidance)

The right dose can vary depending on your health, age, and other medicines you may take. Please check the dosing instructions included with your specific Genegra product and the guidance provided through your pharmacy service.

Common dosing approach

• Starting dose: Many men start at a lower effective dose to reduce the risk of side effects.
• Adjustments: If needed, the dose may be adjusted based on response and tolerability.
• Maximum frequency: Do not take more often than the product instructions recommend (frequently no more than once per day for sildenafil products).

Special considerations

• Older men: Dosing may start lower and be adjusted carefully.
• Liver impairment: Reduced metabolism may increase exposure—dose adjustments are often needed.
• Kidney impairment: May require careful dosing.
• Concomitant medicines: Certain drugs strongly affect sildenafil levels and may require a different plan or avoidance.

If you are unsure what dose is appropriate for you, speak with a healthcare professional before using Genegra.

Food interactions

Food can influence how quickly sildenafil is absorbed. In particular:

• High-fat meals: A heavy or high-fat meal may delay the onset of action and reduce how quickly you feel effects.
• Light meals: A lighter meal may have less impact on timing.

Practical tip: If you want more predictable timing, consider taking Genegra on a relatively lighter stomach and allowing the usual onset window of 30–60 minutes.

Alcohol and medicine interactions

Alcohol

Alcohol can worsen erectile dysfunction by affecting blood vessels and nervous system signals. It may also increase side effects such as dizziness or headache.

• For best results, keep alcohol moderate.
• Avoid excessive drinking, especially if you experience light-headedness.

Do not combine with nitrates (important)

Sildenafil can cause a drop in blood pressure. Medicines that contain nitrates used for chest pain (angina) can have dangerous interactions with sildenafil.

• Avoid taking Genegra with nitrate medicines (e.g., nitroglycerin/glyceryl trinitrate, isosorbide preparations, and other nitrate therapies).
• If you use nitrates, do not use sildenafil unless a clinician specifically advises a safe plan.

Alpha-blockers (for prostate/urinary symptoms or blood pressure)

If you take alpha-blockers such as tamsulosin or similar medicines, there is a potential for dizziness or blood pressure changes.

• Your clinician/pharmacist may recommend specific timing or a starting dose strategy.
• Be cautious when standing up to avoid faintness.

Blood pressure medicines

Sildenafil can add to the blood pressure–lowering effects of some medications. This may increase risks of dizziness or fainting in sensitive individuals.

Medicines that may increase sildenafil levels

Certain medicines can increase sildenafil blood levels, raising the risk of side effects. Examples include:

• Some antifungal medicines (e.g., ketoconazole, itraconazole)
• Some antibiotics (e.g., clarithromycin)
• HIV protease inhibitors
• Cobicistat/ritonavir-containing regimens may also increase levels

Medicines that may decrease sildenafil levels

Some medicines can reduce sildenafil effectiveness by speeding its metabolism. Examples include:

• Rifampicin (TB treatment)
• Some anticonvulsants (e.g., carbamazepine, phenytoin)
• St John’s wort (herbal supplement)

Other ED medicines

Do not combine Genegra with other PDE5 inhibitors (such as other sildenafil products or tadalafil) unless specifically directed by a healthcare professional.

“Stimulant” and recreational substances

Using sildenafil alongside recreational drugs or unknown supplements can increase cardiovascular and blood-pressure risks. If you have any concerns, consult a healthcare professional.

Safety profile (who should be careful)

Most men tolerate sildenafil well when used correctly. However, some conditions and situations increase risk. Consider the following safety points.

Common side effects

• Headache
• Flushing (warmth/redness)
• Indigestion or upset stomach
• Nasal congestion
• Dizziness
• Visual changes (e.g., a bluish tint or increased light sensitivity in some men)

Seek urgent medical help

Stop using sildenafil and seek urgent medical assistance if you experience:

• Chest pain or symptoms of a heart problem
• Severe dizziness or fainting
• Sudden vision loss or severe sudden eye pain
• Sudden hearing loss (rare but reported)
• Priapism—an erection lasting 4 hours or longer (emergency)
• Serious allergic reaction (swelling of face/lips, trouble breathing, rash)

Heart and cardiovascular safety

Sexual activity itself can stress the heart. Sildenafil may also lower blood pressure. Men with known cardiovascular disease should ensure sexual activity is safe and discuss ED treatment options with a clinician.

• If you have been advised not to engage in sexual activity, do not use Genegra without medical advice.
• Be alert for exertional chest pain symptoms.

Conditions affecting dosage and risk

• Low blood pressure or significant cardiovascular instability
• Severe liver impairment
• Severe kidney impairment
• Certain blood disorders (increased risk of priapism)
• Existing eye conditions such as severe vision impairment disorders

Practical use tips

• Start with a test dose: Try Genegra when you’re not rushing—so you can observe your timing and response.
• Give it time: If you take it too late, you may not get the intended effect at the time you need it.
• Use sexual stimulation: Sildenafil supports arousal; it doesn’t replace it.
• Hydrate sensibly: Dehydration can make light-headedness more likely.
• Limit heavy meals beforehand: Especially if you want faster onset.
• Plan for side effects: If you feel dizzy, avoid driving or risky activities until you know how you react.

If Genegra doesn’t seem to work, common reasons include incorrect timing, high-fat meals, insufficient stimulation, or drug interactions that change sildenafil levels. Adjusting timing and checking interactions can help.

Alternative options

If Genegra is not right for you, other treatment options may be available depending on your situation and medical history.

Other PDE5 inhibitors

• Tadalafil (often has a longer duration; some men prefer flexibility)
• Vardenafil
• Avanafil

Non-PDE5 options

• Vacuum erection devices (mechanical approach)
• Intracavernosal injections or intraurethral therapy (specialist-guided)
• Hormone evaluation if low testosterone or other endocrine causes are suspected
• Psychological and lifestyle approaches (stress, relationship factors, smoking cessation, exercise, weight management)

The best option depends on your health conditions, preferences, and which medications you already take.
