Tadora (Tadalafil) — Patient Information (Australia)

Tadora contains tadalafil, a medicine used for erectile dysfunction and certain other conditions. This guide explains how Tadora works, how to take it, what to expect, and important safety information. It is written for patients in Australia and uses clear, practical language.

Quick overview

Basic product information

Brand name: Tadora
Active ingredient: Tadalafil
Medicine type: Phosphodiesterase type 5 (PDE5) inhibitor
Forms and strengths: Tadora is available in tablet form in different strengths (commonly 5 mg, 10 mg, and 20 mg—availability can vary by pharmacy). Your product pack will list the exact strength.

Tadalafil belongs to a group of medicines known as PDE5 inhibitors. These medicines help improve blood flow in certain circumstances by acting on specific enzymes in the body.

How Tadora works (mechanism of action)

When sexual stimulation occurs, the body releases signals that increase blood flow to the penis. PDE5 is an enzyme that breaks down a chemical messenger called cGMP. Tadalafil inhibits PDE5, which helps:

• Maintain higher cGMP levels for longer
• Relax smooth muscle in blood vessel walls
• Support improved blood flow where it is needed

Importantly, Tadora helps with the response to sexual stimulation; it does not automatically cause an erection without stimulation.

Pharmacokinetics (how the body handles tadalafil)

“Pharmacokinetics” describes how a medicine is absorbed, distributed, metabolised, and eliminated.

• Absorption: Tadalafil is absorbed after oral dosing. Peak levels generally occur within a few hours.
• Onset: Many people notice effects within about 30–60 minutes, but timing can vary.
• Duration: Tadalafil is long-acting. Clinical effects can last up to around 36 hours in erectile dysfunction.
• Metabolism: Tadalafil is metabolised mainly in the liver (via CYP pathways).
• Elimination: It is removed from the body through both metabolism and excretion. The long half-life is part of why it lasts so long.

If you have liver or kidney impairment, the way tadalafil works in your body may change. Your dosing may need adjustment.

Typical uses (indications)

Tadalafil can be used for different conditions. The appropriate dose and schedule depend on the specific indication.

• Erectile dysfunction (ED): Helps achieve and maintain an erection suitable for sexual activity.
• Benign prostatic hyperplasia (BPH) / lower urinary tract symptoms: Helps relieve symptoms such as difficulty starting urination, weak stream, urgency, and frequent urination.
• Pulmonary arterial hypertension (PAH): Helps improve exercise capacity and delay clinical worsening by affecting blood vessel tone in the lungs. (This use depends on local product guidance and specialist management.)
• Combination decisions: Sometimes tadalafil and other medicines may be used together for symptom control—your clinician will advise what is appropriate for your situation.

Who might benefit?

Tadora may be suitable if you have ED and you are otherwise safe to use a PDE5 inhibitor. It may also help with urinary symptoms due to BPH or with PAH in appropriate patients.

You should not use tadalafil if you have certain medical conditions or take certain medicines that can cause dangerous interactions (see “Alcohol and medicine interactions” and “When to avoid Tadora”).

Dosing — how to take Tadora

Dosing depends on the condition, your overall health, and how you respond. Always follow the dose written on your medicine label and any advice provided by a qualified healthcare professional.

1) For erectile dysfunction (ED)

Two common approaches are used:

• As-needed dosing: Often taken before anticipated sexual activity. Many people take tadalafil at least 30 minutes before sexual activity.
• Once-daily dosing: A low daily dose may help you be ready more often without planning timing each time.

Practical timing tip: Because tadalafil can act for a long time, the “window” may extend beyond a single evening. You do not need to take multiple doses close together.

2) For BPH (lower urinary tract symptoms)

BPH dosing is commonly taken once daily. This approach targets urinary symptoms over time rather than for immediate “on/off” effects.

3) For pulmonary arterial hypertension (PAH)

PAH dosing schedules are typically specific and may require specialist care. Follow the dosing plan provided for your condition.

Missed dose

• If you are taking tadalafil once daily and miss a dose, take it when you remember unless it is close to the next dose. Do not take a double dose.
• If you take it as needed, skip the missed dose and resume your usual schedule when appropriate.

Do not exceed the prescribed dose

Taking more than recommended increases the risk of side effects and interactions without improving safety or effectiveness.

Timing: when does it work?

• As-needed ED use: Many people experience effects within about 30–60 minutes, though individual variation is normal.
• Duration: Effects may last up to ~36 hours for ED. You may find it easier to plan around this extended window.
• Daily dosing: With daily use, symptom control may take several days, depending on the condition and your response.

Remember: Sexual stimulation is required for erections. Tadalafil does not replace the need for stimulation.

Food interactions (including fatty meals)

Tadalafil can be taken with or without food. However, food may influence the speed of onset.

• Fatty meals: A very heavy or fatty meal may delay absorption and slightly delay onset in some people.
• Alcohol with meals: See the alcohol section for key safety points.

If you want to fine-tune timing for ED, consider taking Tadora on a day when meals are typical rather than extremely heavy, and observe how you respond.

Alcohol and medicine interactions

Alcohol

Alcohol can affect sexual performance and can increase the likelihood of side effects such as dizziness, low blood pressure, or headache. For safety:

• Keep alcohol moderate.
• Avoid binge drinking before taking tadalafil.
• Be cautious if you feel light-headed or unwell.

Alcohol and tadalafil together may increase the risk of hypotension (low blood pressure), especially in people who are sensitive to blood pressure changes.

Medicines that can cause dangerous interactions

Some medicines must not be used with tadalafil due to the risk of serious low blood pressure or other complications.

• Nitrates (for chest pain) — for example, glyceryl trinitrate (GTN) or isosorbide preparations.
  Do not combine.
• “Nitrite” recreational drugs — can behave like nitrates and can be dangerous.
• Riociguat (for certain pulmonary hypertension conditions).
  Do not combine.

Alpha-blockers (for prostate symptoms or blood pressure)

Medicines in the alpha-blocker class (used for BPH or hypertension) can also lower blood pressure. Combining them with tadalafil can cause dizziness or fainting in some people.

• Extra caution is required.
• Doses may need to be started gradually and timed carefully.

Blood pressure medicines

If you use antihypertensives, the combination may increase the likelihood of light-headedness or low blood pressure, especially at the start.

Other PDE5 inhibitors

• Do not take tadalafil with other PDE5 inhibitors (such as sildenafil or vardenafil).
• This increases side effect risk without added benefit.

HIV medicines, antifungals, and some antibiotics

Certain medicines can raise tadalafil levels in the body (which can increase side effects), while others may reduce levels. Examples include:

• Some antifungal medicines
• Some HIV medicines
• Some antibiotics (for example, certain macrolides)
• Some anti-seizure medicines (may reduce tadalafil effect)

If you take regular medicines, check them with a pharmacist to confirm there are no important interactions.

Safety profile — common and serious side effects

Common side effects

Many side effects are mild and may improve as your body adjusts. Commonly reported effects include:

• Headache
• Flushing (warmth/redness)
• Indigestion / stomach discomfort
• Back pain or muscle aches
• Nasal congestion
• Dizziness

Less common but important warnings

• Vision changes: Seek urgent medical attention if you experience sudden vision loss or severe visual disturbances.
• Hearing changes: Sudden hearing decrease or ringing in the ears should be treated as urgent.
• Chest pain: If chest pain occurs, follow local emergency guidance and avoid further doses until reviewed.

Priapism (prolonged erection)

Rarely, PDE5 inhibitors can cause a prolonged erection lasting more than a few hours. This is a medical emergency because it can damage tissue.

• If an erection lasts too long (for example, more than 4 hours), seek emergency care.

Low blood pressure (hypotension)

Symptoms can include dizziness, fainting, blurred vision, or feeling unusually weak. If you feel these effects, do not take another dose and seek advice promptly.

When to avoid or use extra caution

Tadora may not be suitable for everyone. Talk to a pharmacist about your medical history, especially if you have:

• Heart conditions or unstable angina
• Severe low blood pressure or a history of fainting
• Significant liver disease
• Severe kidney impairment
• Retinitis pigmentosa (a rare inherited eye condition)
• Bleeding disorders or a history of stroke
• Conditions increasing the risk of priapism (for example, certain blood disorders or anatomical penile conditions)

If you have had an allergic reaction to tadalafil or any ingredient, do not use the product.

Practical use tips

Set yourself up for success (ED)

• Give yourself enough time: Plan for a window that allows it to take effect.
• Focus on stimulation: Ensure there is sexual stimulation before expecting an erection.
• Manage stress: Anxiety can interfere with erectile response, even if the medicine is working.
• Consider lifestyle factors: Smoking, excessive alcohol, lack of sleep, and certain diets can worsen ED.

Reduce side effects

• Start with the lowest effective dose (if your prescriber has advised this approach).
• Stand up slowly if you feel dizzy.
• Stay hydrated and avoid heavy meals and excessive alcohol close to dosing if you are sensitive.

Track your response

If you’re trying tadalafil for ED, note what dose you used, when you took it, whether you ate heavily, and how it affected you. This can help your healthcare professional fine-tune timing.

Alternative options

Depending on the reason you need treatment, there are several alternative approaches. Options may include lifestyle changes, other medicines, or therapies.

For erectile dysfunction

• Other PDE5 inhibitors: such as sildenafil or vardenafil (different onset and duration profiles).
• Non-oral options: vacuum erection devices, injections, or suppositories may be considered for some individuals.
• Address underlying causes: cardiovascular health, diabetes, medication side effects, and mental wellbeing all influence ED.

For BPH symptoms

• Alpha-blockers (commonly used for urinary symptoms)
• 5-alpha reductase inhibitors (in specific prostate size situations)
• Combination therapy may be used in certain patients under medical guidance

For PAH

• PAH treatment often involves specialist-directed therapy, which may include other classes such as endothelin receptor antagonists or prostacyclin pathway medicines.

A pharmacist can help you compare options and discuss suitability based on your health conditions and medicines.
