Executive summary
Tadalafil is the active component in Cialis. It is a phosphodiesterase type 5 (PDE5) inhibitor that relaxes smooth muscle and increases blood flow in targeted tissues. Its primary licensed use in men is to treat erectile dysfunction (ED). Formulations of tadalafil at different doses are also used for symptoms of benign prostatic hyperplasia (BPH) and, under other trade names and regimens, for pulmonary arterial hypertension.
Surveying the sections on the study maps how the dynamics of interactions evolve over time. and status under Australian law for related practical essential information.
Fundamental facts in one glance
- The formulation's active ingredient is tadalafil.
- Main use: treatment of erectile dysfunction; some doses for BPH under medical advice.
- Tablet strengths commonly sold in Australia are 2.two copies of 5 mg, then 10 mg and 20 mg.
- Typical distinguishing feature: longer duration of action compared with many other PDE5 inhibitors, up to 36 hours.
Preventive steps and when to avoid using it tadalafil
Do not take tadalafil if you are using nitrates for angina or chest pain. Examples include nitroglycerin products and isosorbide compounds. Recreational amyl nitrite products, often called "poppers", also contain nitrites and must be avoided. Combining nitrates and tadalafil can produce a severe and real potentially life-threatening fall in blood pressure.
Avoid tadalafil if you are on riociguat. Discuss with your prescriber before taking tadalafil if you have any of the following:
- Recent myocardial infarction (within 90 days) or recent stroke/heart failure (within 6 months).
- Unstable angina or serious heart rhythm disturbance.
- Poorly controlled high or low blood pressure.
- Severe hepatic disorder or renal impairment including dialysis.
- Blood dyscrasias such as sickle cell disease, multiple myeloma or leukaemia.
- Active bleeding problems or active peptic ulcer disease.
- Inherited retinal disorders or a history of sudden visual loss.
- Penile anatomical deformities like Peyronie disease.
Reports of rare sudden vision loss and rare hearing changes have been linked to PDE5 inhibitors; these events are more likely in people with vascular risk factors. Older adults may need dose changes. Tadalafil is not indicated for use in pregnancy; female use and lactation data are limited.
Guidelines for taking tadalafil
General advice for oral tablets:
- Swallow the pills whole with water.
- For on-demand ED treatment, take approximately 30 to 60 minutes before sexual activity; sexual stimulation is required for efficacy.
- Limit dosing to once per 24 hours for on-demand use.
- Fatty meals may delay the onset of effect; many choose to avoid heavy meals around dosing.
- For continuous benefit, low-dose daily regimens (2.5 mg or 5 mg) can be prescribed; take at the same time each day.

- Alpha-blockers used for blood pressure or prostate symptoms (for example doxazosin, tamsulosin) - risk of low blood pressure.
- Strong CYP3A4 inhibitors such as ketoconazole or itraconazole - may increase tadalafil levels.
- CYP3A4 inducers such as rifampin or certain anticonvulsants - may reduce tadalafil levels.
- Some antibiotics and antiviral agents, certain antidepressants and antiarrhythmics - discuss as advised by your prescriber.
- Grapefruit products can modify tadalafil exposure.

Options and similar medications
Other PDE5 inhibitors commonly used for ED include sildenafil (Viagra), vardenafil (Levitra) and avanafil (Spedra). Key practical differences are:
- Sildenafil: onset usually 30 to 60 minutes; effect duration about 4 to 6 hours.
- Vardenafil: similar onset and duration to sildenafil but with a slightly different side effect profile for some people.
- Avanafil: may act faster in some users, sometimes within 15 to 30 minutes, with several hours of effect.
- Non-oral options: alprostadil is available as an injection or urethral suppository for patients unsuitable for PDE5 inhibitors.
Run a comparisond with these options, tadalafil often provides a longer window of opportunity for sexual activity, and a low-dose daily regimen can offer more spontaneity. Choice depends on individual response, tolerance, comorbidities and cost. Consider the options together with your treating clinician.
