Tadagra Strong: Confidential Prescriptions by Clinicians - in Australia

Big picture summary

Tadagra Strong is a brand of oral tablet that contains tadalafil as the active molecule. It is most commonly prescribed for erectile dysfunction (ED). In certain clinical contexts tadalafil is also used to improve symptoms of benign prostatic hyperplasia (BPH) and, under specialist supervision, to manage pulmonary arterial hypertension (PAH).

• Active element: tadalafil
• Typical marketed strength for this product: 40 mg tablet
• Central cues: erectile dysfunction, BPH symptom relief, specialist PAH therapy

This is important: On-demand ED dosing is usually 10 mg or 20 mg. A 40 mg tablet exceeds common on-demand doses and may raise the likelihood of adverse reactions. Use only if specifically recommended by a prescriber. See Dosing and Delivery Methods for how to swallow it and Situations in which this treatment is not advised and Operational warnings Guidance for safety limits.

Pharmacologic mechanism of action

Tadalafil is part of the phosphodiesterase type 5 (PDE-5) inhibitor family. By blocking PDE-5 it supports the nitric oxide pathway in penile blood vessels, promoting smooth muscle relaxation and improved blood flow during sexual stimulation, which assists in achieving and maintaining an erection. In BPH it can relax prostate and bladder neck muscles, easing urinary flow. For PAH, tadalafil reduces pulmonary vascular resistance but must be prescribed and monitored by a specialist.

Dosing and Drug Administration

General instructions for use:

• Take a single tablet about 30 to 60 minutes before sexual activity if using as needed.
• Swallow tablets whole with water; avoid breaking or chewing them.
• It may be taken with food or on an empty stomach; very high fat meals can delay onset.
• One dose maximum per 24 hours.
• Avoid grapefruit and grapefruit juice as they can increase tadalafil concentrations.

Common regimens clinicians select for ED are 10 mg to 20 mg when required, or a lower daily dose such as 2.5 mg to 5 mg for regular therapy. The 40 mg formulation associated with Tadagra Strong is higher than typical ED doses and should not be used without explicit medical advice. Specialist PAH regimens sometimes use 40 mg once daily; do not interchange formulations without specialist instruction.

If your health or other medicines change, consult your doctor or pharmacist before continuing treatment. See further OTC and Prescription Drug Interactions among users and Safety guidelines.

Safety care steps

Tell your prescriber about any of the following prior to beginning tadalafil:

• Diseases of the cardiovascular system, prior heart attack or stroke, or an irregular heartbeat.
• Unstable angina, uncontrolled blood pressure, or untreated pulmonary hypertension.
• Pulmonary veno-occlusive disease.
• Advanced liver impairment or advanced kidney disease, including dialysis.
• Retinal diseases that are hereditary, including retinitis pigmentosa or any unexplained vision loss episodes.
• Blood disorders that predispose to prolonged erections, for example sickle cell disease, leukemia, or multiple myeloma.
• Penile anatomical abnormalities or a history of priapism (erection longer than 4 hours).
• Active peptic ulcers or any condition that makes sexual activity hazardous.

Alcoholic beverage product can worsen dizziness or low blood pressure when combined with tadalafil. Consider limiting alcohol intake while taking this medicine.

Alert: Safety Alert notices and Cases where treatment is not appropriate

• If you have a known hypersensitivity to tadalafil or any ingredient in the tablet, avoid use.
• Concurrent use of nitrates, for example nitroglycerin, isosorbide mononitrate or isosorbide dinitrate.
• Use of the soluble guanylate cyclase stimulator riociguat.

Using recreational nitrates such as amyl nitrite or "poppers" together with tadalafil is dangerous and can cause a sudden and profound drop in blood pressure. If you are prescribed nitrates for heart conditions, tadalafil is not suitable.

Drug related adverse effects - Common and Serious

Key deleterious effects are typically mild and transient:

• A cephalalgia with facial flushing, or nasal congestion
• Gastric discomfort, nausea or upper abdominal discomfort
• Back related pain, muscle aches or limb pain
• Feeling dizzy, especially if combined with alcohol or blood pressure medicines

Seek urgent medical attention if you develop chest pain, sudden loss of vision or hearing, seizures, severe allergic symptoms, or a painful erection lasting more than 4 hours.

Potential Interactions Between Drugs

Provide your prescriber with a full list of all prescription drugs, over-the-counter medicines and supplements. Principal contact moments include:

• Nitrates and other nitric oxide donors, and riociguat - these are contraindicated. See Exclusion criteria for therapy, Alerts, and Operational warnings.
• Other PDE-5 inhibitors used for ED or PAH.
• Strong CYP3A4 inhibitors such as ketoconazole, itraconazole, clarithromycin and ritonavir which may raise tadalafil blood levels.
• CYP3A4 inducers like rifampicin, carbamazepine, phenytoin or Perennial herb Hypericum perforatum which can reduce tadalafil effectiveness.
• Antihypertensive agents and alpha-blockers which may exaggerate blood pressure lowering.
• Certain antiviral agents used for HIV or hepatitis C that alter CYP3A4 metabolism.
• Grapefruit or grapefruit juice which may increase tadalafil concentration. See Administration and Dose.

Lapsed dose

• If you use tadalafil as needed, there is no fixed schedule; do not take an extra tablet to make up for a missed occasion.
• If you are on a daily prescription and miss a dose, take it as soon as you remember unless the next scheduled dose is near. Do not work in pairs to catch up.

ODing

If you suspect an experienced an overdose call emergency services or travel toward the nearest hospital immediately. Symptoms of experienced an overdose may include severe dizziness, fainting, or a prolonged painful erection. If possible, bring the medication packaging with you.

Storage systems

• Store tablets at room temperature away from excessive heat and humidity.
• Keep the medicine in its original container and out of reach of children.

Related Medications and Alternatives

If tadalafil is not suitable for you or is unavailable, clinicians may discuss other options. Budget-friendly choice variations include:

• Sildenafil (for example Viagra and generic versions) - generally faster onset but shorter duration than tadalafil.
• Vardenafil (Levitra and generics) - broadly similar to sildenafil with different food effects in some cases.
• Avanafil aka Spedra - may act faster with a shorter overall duration for some users.
• Branded tadalafil (Cialis) - available in lower daily doses (2.5 mg and 5 mg) and as on-demand 10 mg and tablets providing twenty milligrams.
• Non-drug interventions - vacuum erection devices, intracavernosal injections, lifestyle changes, weight loss and psychological therapy.

Which option is best depends on how quickly you want onset, how long you want effects to last, side effect profiles, cost and other medications you take. See How prices run in Australia for approximate comparisons.
