Intro and a quick outline and Key Findings
The principal active ingredient is vardenafil. (commonly known by the brand name Levitra).
Its primary purpose is to treat erectile dysfunction in adult men. Vardenafil belongs to the phosphodiesterase type 5 (PDE5) inhibitor class and helps produce and maintain an erection when sexual stimulation occurs. Onset is commonly within 30 to 60 minutes for many men, with effects lasting around 4 to 5 hours in most cases.
Tablet strength options on hand in Australia: typically 10 mg and 20 mg. For more on how it compares to other agents, see the section Different Options and Side by Side Comparisons.
If you are an athletea review meeting the notes on regulatory standards under The Regulatory and Legal Position in Australia prior to using.

How to Take Advantage of This
Typical instructions:
- Take the tablets with water. They may be taken with or without food, but a very heavy or fatty meal can delay onset.
- Take the dose about one hour before sexual activity. The effectiveness of the medicine depends on sexual stimulation.
- Do not use more than one dose in any 24-hour period. Do not take extra tablets if a dose seems ineffective.
- Use only the formulation prescribed to you; do not share your prescription with others.
Forgotten dose
Vardenafil is taken as needed. There is no schedule to catch up; do not take an extra dose to make up for a missed occasion.
Overdosed
If you suspect an deliberate overdose, contact the Australian Poisons Information Centre on 13 11 26 or proceed to the nearest emergency department without delay.
Potential Drug Food Interactions in the system
Certain combinations can produce serious hypotension or other undesirable health effects. Review all medicines, including supplements and herbal products, with your doctor.
Combinations with conditions that rule out this therapy
- Nitrates used for angina or chest pain (for example nitroglycerin, isosorbide mononitrate/dinitrate) and recreational inhaled nitrates such as amyl nitrite or butyl nitrite. These combinations can cause dangerous drops in blood pressure.
- Riociguat, a soluble guanylate cyclase stimulator.
- Certain QT-prolonging agents such as cisapride or pimozide; confirm with your healthcare provider.
Medicines that may require dose adjustment or caution
- Alpha blockers (for example tamsulosin, doxazosin) — coadministration can cause symptomatic low blood pressure; start under medical supervision.
- Strong CYP3A4 inhibitors that elevate vardenafil levels, including some macrolide antibiotics and azole antifungals, certain HIV protease inhibitors, and grapefruit juice.
- Enzyme inducers that may decrease vardenafil exposure, such as rifampin, carbamazepine, phenytoin and phenobarbital.
- Certain antiarrhythmics and other cardiac medicines; consult your cardiologist if relevant.
- Some antidepressants and antipsychotics may interact; check with your prescriber for a tailored assessment.
Alcohol bottle and tobacco can influence effectiveness and ill effects. Discuss lifestyle factors with your clinician by your side. For safety integrity through watchful oversight counsel and tips see Monitoring and Safety safety measures.

Snappy FAQs
How quickly does vardenafil start working? Many men notice an effect within 30 to 60 minutes. A fatty meal can delay absorption.
Is it wise to drink alcohol from a safety standpoint? Moderate alcohol intake may be acceptable, but excessive alcohol can reduce erectile function and increase dizziness. See Food Effects on Medication in order to provide more context.
Are tablets able to be halved? Only split tablets that are plain and scored. Do not split film-coated or orally disintegrating tablets unless instructed by your pharmacist.
Can this be safe for someone with heart disease? Some patients with stable cardiac disease can use PDE5 inhibitors, but you must be assessed and cleared by your doctor. Never combine with nitrates. See Who might need to consult a doctor and Cautionary Measures and Environmental monitoring.
