Megalis Information

Introduction

Megalis is a medication indicated for the treatment of erectile dysfunction (ED) and other men’s health conditions. Its active ingredient is tadalafil, a phosphodiesterase‑5 (PDE‑5) inhibitor that belongs to the erectile dysfunction therapeutic group. In Hong Kong, men who experience difficulty achieving or maintaining an erection may be prescribed Megalis as part of a comprehensive approach to sexual health. The drug is also used off‑label for pulmonary arterial hypertension under a different brand name, reflecting its vascular‑relaxing properties.

What is Megalis?

Megalis is a tablet formulation that contains 5 mg, 10 mg, or 20 mg of tadalafil per unit. The product is manufactured by a licensed pharmaceutical company that complies with Good Manufacturing Practice (GMP) standards required by the Hong Kong Department of Health. While Megalis is marketed under its own brand name, it contains the same active compound as well‑known products such as Cialis®, Adcirca® and Tadalis®. As a generic formulation, Megalis offers an affordable alternative without compromising efficacy or safety when sourced from reputable suppliers.

How Megalis Works

Tadalafil inhibits the enzyme phosphodiesterase‑5 (PDE‑5) found in the smooth muscle lining of the corpus cavernosum and pulmonary vasculature. By blocking PDE‑5, tadalafil prevents the breakdown of cyclic guanosine monophosphate (cGMP), a messenger that promotes smooth‑muscle relaxation and vasodilation. In the penis, increased cGMP levels enhance blood inflow during sexual stimulation, leading to an erection. The drug’s onset of action typically occurs within 30 minutes, and its pharmacologic effect can last up to 36 hours, providing a flexible therapeutic window. Tadalafil is metabolized primarily by the liver enzyme CYP3A4 and eliminated via feces and urine, with a half‑life of approximately 17.5 hours.

Conditions Treated with Megalis

• Erectile Dysfunction (ED) – The primary indication. ED affects an estimated 30 % of men over 40 in Hong Kong, with prevalence rising with age and comorbidities such as diabetes and hypertension.
• Benign Prostatic Hyperplasia (BPH) associated lower urinary tract symptoms – Tadalafil 10 mg once daily improves urinary flow and reduces symptom scores.
• Pulmonary Arterial Hypertension (PAH) – Although prescribed under a different brand, the same pharmacologic action reduces pulmonary vascular resistance, improving exercise capacity.

Megalis is effective for these conditions because PDE‑5 inhibition directly addresses the underlying vascular dysfunction that contributes to impaired erectile response, urinary obstruction, or elevated pulmonary pressures.

Who is Megalis For?

• Adults with diagnosed erectile dysfunction who desire an on‑demand or daily regimen.
• Men with BPH‑related urinary symptoms who benefit from a once‑daily dose.
• Patients with PAH who require sustained pulmonary vasodilation (under specialist supervision).

Contraindications include patients using nitrates, those with severe uncontrolled hypertension, or individuals with a known hypersensitivity to tadalafil or any tablet excipients. Caution is advised for men with moderate hepatic or renal impairment, as dose adjustments may be necessary.

Risks, Side Effects, and Interactions

Common

• Headache
• Dyspeasia (indigestion)
• Nasal congestion
• Back pain or muscle aches (often occurring 12–24 h after dosing)
• Flushing

These effects are usually mild, transient, and resolve without medical intervention.

Rare

• Dizziness or vertigo
• Vision changes (e.g., blurred vision, blue‑tinted perception)
• Hearing loss or tinnitus
• Priapism (prolonged erection lasting > 4 h)

Patients experiencing any of these rare events should seek prompt evaluation.

Serious

• Cardiovascular events (myocardial infarction, stroke) in patients with pre‑existing heart disease.
• Severe hypotension, especially when combined with nitrates or potent vasodilators.
• Anaphylactic reactions (rash, swelling, airway compromise).

Any serious adverse event warrants immediate medical attention.

Clinically Relevant Drug Interactions

• Nitrates (e.g., nitroglycerin, isosorbide dinitrate) – concurrent use can cause profound hypotension.
• Alpha‑blockers (e.g., tamsulosin) – may increase the risk of symptomatic hypotension.
• CYP3A4 inhibitors ( – can raise tadalafil plasma concentrations, necessitating dose reduction.
• CYP3A4 inducers (e.g., rifampin, carbamazepine) – may lower effectiveness.

Patients should provide a full medication list to their healthcare provider before initiating Megalis.

Practical Use: Dosing, Missed Dose, Overdose

• On‑demand dosing: 10 mg or 20 mg taken at least 30 minutes before anticipated sexual activity. Do not exceed one dose per 24 hours.
• Daily dosing for BPH: 5 mg taken at the same time each day, with or without food.
• Missed dose: For on‑demand use, skip the missed dose and take the next dose when needed. For daily use, take the missed tablet as soon as remembered unless it is within 12 hours of the next scheduled dose; in that case, skip the missed tablet to avoid double dosing.
• Overdose: Symptoms may include severe headache, flushing, hypotension, or prolonged erection. Seek emergency medical care promptly.

Precautions: High‑fat meals may delay absorption but do not affect overall efficacy. Moderate alcohol consumption generally does not interfere, though excessive intake can increase the risk of hypotension and dizziness. Patients with cardiovascular disease should discuss activity level and safety with a physician before use.

FAQ

• Is Megalis available in multiple tablet strengths?
  Yes, Megalis is marketed in 5 mg, 10 mg, and 20 mg tablets, allowing clinicians to tailor therapy to individual response and dosing schedules.

• Can I store Megalis in a bathroom cabinet?
  Megalis should be kept at controlled room temperature, away from excessive heat, moisture, and direct sunlight. A bathroom cabinet may expose the tablets to humidity, which could degrade potency over time.

• Does the formulation contain any allergens such as lactose or gluten?
  The inactive ingredients typically include microcrystalline cellulose, calcium hydrogen phosphate, and magnesium stearate. Neither lactose nor gluten is listed, but patients with severe sensitivities should verify the specific batch label.

• How does Hong Kong’s personal import limit affect ordering Megalis?
  Hong Kong permits the personal import of a three‑month supply of a prescription medication for personal use, provided the product is for the importer’s own health needs and is accompanied by a valid prescription when requested by customs.

• Will taking Megalis affect routine drug‑testing at work?
  Standard workplace drug screens do not test for PDE‑5 inhibitors. Therefore, Megalis use is unlikely to be detected in typical occupational drug‑testing panels.

• Is there a difference between the Asian‑market and Western‑market Megalis tablets?
  The active ingredient and dosage strength are identical worldwide. Minor variations may exist in tablet coating or excipients to meet regional regulatory preferences, but therapeutic effect remains equivalent.

• What is the historical significance of tadalafil in erectile‑dysfunction therapy?
  Tadalafil was first approved by the U.S. FDA in 2003, introducing a longer duration of action compared with earlier PDE‑5 inhibitors. Its extended therapeutic window facilitated flexible dosing and contributed to broader acceptance of oral ED treatments.

• Can Megalis be taken with antihypertensive medication?
  Generally, concurrent use with commonly prescribed antihypertensives (e.g., ACE inhibitors, beta‑blockers) is safe. However, caution is advised when combined with medications that also lower blood pressure, such as alpha‑blockers, to prevent additive hypotensive effects.

• Does traveling at high altitude influence Megalis effectiveness?
  High altitude can affect oxygen saturation and vascular tone, but no clinically significant interaction with tadalafil has been reported. Patients with underlying pulmonary conditions should discuss travel plans with a healthcare professional.

• Are there any differences between Megalis and the brand‑name Cialis® tablet appearance?
  Cialis® tablets are often scored and may have a distinct imprint, while Megalis tablets carry their own manufacturer’s imprint and may not be scored. The visual differences do not alter the pharmacologic activity.

Glossary

Phosphodiesterase‑5 (PDE‑5) inhibitor
