Generic Cialis Information

Introduction

Cialis (generic name: tadalafil) is a phosphodiesterase‑5 (PDE‑5) inhibitor indicated primarily for the treatment of erectile dysfunction (ED) in adult men. In Hong Kong, it is prescribed by physicians and supplied through licensed pharmacies. The medication is manufactured by Eli Lilly and related companies, and belongs to the men’s health therapeutic group. In addition to ED, tadalafil is approved for benign prostatic hyperplasia (BPH) and, in a higher dose, for pulmonary arterial hypertension under the brand name Adcirca.

What is Cialis?

Cialis is a prescription medication that contains the active compound tadalafil, a selective PDE‑5 inhibitor. It was developed by Eli Lilly and first approved by the U.S. Food and Drug Administration in 2003. The drug is available in tablet form with strengths of 2.5 mg, 5 mg, 10 mg, and 20 mg. Cialis is marketed as a long‑acting option for erectile dysfunction, providing flexibility for on‑demand or daily dosing regimens.

How Cialis Works

Tadalafil blocks the enzyme phosphodiesterase‑5, which normally degrades cyclic guanosine monophosphate (cG → cGMP) in the smooth muscle of the corpus cavernosum. By inhibiting PDE‑5, tadalafil allows cGMP to accumulate, leading to smooth‑muscle relaxation and increased blood flow during sexual stimulation. The drug is absorbed rapidly, reaching peak plasma concentrations in 2 hours (range 1–3 h). Its elimination half‑life is approximately 17.5 hours, which supports a therapeutic window of up to 36 hours after dosing. Clearance occurs mainly via hepatic metabolism (CYP3A4) and renal excretion of metabolites.

Conditions Treated with Cialis

• Erectile Dysfunction (ED): Restores the ability to achieve and maintain an erection sufficient for sexual activity.
• Benign Prostatic Hyperplasia (BPH): Improves urinary symptoms such as weak stream, urgency, and nocturia by relaxing smooth muscle in the prostate and bladder neck.
• Pulmonary Arterial Hypertension (PAH): Under the brand Adcirca, the 40 mg dose reduces pulmonary vascular resistance and improves exercise capacity.

In Hong Kong, prevalence studies estimate that 1 in 5 men aged 40 years or older experience some degree of ED, while BPH affects up to 30 % of men over 60. Access to an effective, long‑acting oral agent therefore addresses a substantial burden on men’s health.

Patient Groups Most Likely to Benefit

• Men with intermittent sexual activity who prefer “as‑needed” dosing (10 mg or 20 mg taken at least 30 minutes before intercourse).
• Men requiring daily therapy (2.5 mg or 5 mg) because of frequent sexual activity or co‑existing BPH symptoms.
• Patients with both ED and BPH, where a single daily dose can treat both conditions simultaneously.
• Individuals with PAH who meet the specific dosing criteria for Adcirca (40 mg once daily).

Cautious use is recommended for patients with severe cardiovascular disease, uncontrolled hypertension, recent stroke or myocardial infarction, and those taking nitrates or certain alpha‑blockers.

Risks, Side Effects, and Interactions

Common

• Headache
• Indigestion (dyspepsia)
• Back pain
• Muscle aches (myalgia)
• Nasal congestion
• Flushing

Rare

• Vision changes (blurred vision, blue‑tinted vision)
• Hearing loss or tinnitus
• Priapism (prolonged erection lasting > 4 hours)

Serious

• Cardiovascular events (myocardial infarction, stroke) in patients with pre‑existing disease
• Severe hypotension, especially when combined with nitrates or potent vasodilators
• Allergic reactions (rash, angioedema, anaphylaxis)

Drug–Drug Interactions

• Nitrates (e.g., nitroglycerin, isosorbide dinitrate): Concomitant use can cause marked hypotension; contraindicated.
• Alpha‑blockers (e.g., tamsulosin, doxazosin): May enhance blood‑pressure lowering effects; start with low tadalafil dose and monitor.
• CYP3A4 inhibitors (e.g., ketoconazole, ritonavir): Increase tadalafil plasma concentrations; dose reduction may be required.
• CYP3A4 inducers (e.g., rifampicin, carbamazepine): Decrease efficacy of tadalafil; consider alternative therapy.

Patients should disclose all prescribed, over‑the‑counter, and herbal products before initiating therapy.

Practical Use: Dosing, Missed Dose, Overdose

• On‑demand regimen: 10 mg taken at least 30 minutes before sexual activity; may increase to 20 mg or decrease to 5 mg based on efficacy and tolerability. Do not exceed one dose per 24 hours.
• Daily regimen for ED/BPH: 2.5 mg or 5 mg once daily at the same time each day. The 5 mg dose is typical for combined ED and BPH treatment.
• PAH (Adcirca): 40 mg taken once daily with or without food.

Missed dose: For daily therapy, take the missed dose as soon as remembered, unless it is within 12 hours of the next scheduled dose; in that case, skip the missed dose and resume the regular schedule. No additional dose is required.

Overdose: Signs may include pronounced hypotension, dizziness, or prolonged erection. If overdose is suspected, seek immediate medical attention; supportive care and monitoring are the mainstays of treatment.

Food and alcohol: Food does not significantly affect absorption. Excessive alcohol may increase the risk of hypotension and reduce erection quality; moderate consumption (≤ 2 standard drinks) is advisable.

Comorbidities: Caution is warranted in patients with severe hepatic impairment (dose adjustment) and renal impairment (monitor for accumulation).

FAQ

• Is Cialis available in both brand‑name and generic forms in Hong Kong?
  Yes, both the original brand‑name product (Cialis by Eli Lilly) and generic tadalafil tablets are authorized in Hong Kong. Generic versions contain the same active ingredient and are typically offered at lower cost, making them a practical option for many patients.

• What is the recommended storage condition for tadalafil tablets?
  Tadalafil should be stored at controlled room temperature (15 °C – 30 °C), away from direct sunlight, moisture, and heat sources. Do not refrigerate; keep the medication in its original blister pack until use to preserve potency.

• Can Cialis be used together with antihypertensive medication?
  In most cases, tadalafil can be combined safely with routine antihypertensive agents, provided blood pressure is well controlled. However, caution is needed when the antihypertensive regimen includes nitrates or potent alpha‑blockers, as additive hypotensive effects may occur. Consultation with a physician is essential.

• Does the efficacy of Cialis differ across ethnic groups, such as Asian populations?
  Clinical trials have shown comparable efficacy and safety of tadalafil among Asian participants relative to other ethnicities. No specific dosage adjustment is required solely based on ethnicity, although individual response and tolerability should guide dosing.

• Is it legal to import Cialis for personal use into Hong Kong?
  Importation of prescription medicines for personal use is permitted when the product is accompanied by a valid prescription from a Hong Kong‑registered doctor. Our online pharmacy facilitates the professional evaluation step to ensure compliance with local regulations before shipping.

• What packaging does Cialis come in when ordered online?
  Orders from our pharmacy are delivered in discreet, tamper‑evident packaging. Tablets are placed in a sealed, opaque pouch inside a plain cardboard box, containing only the essential labeling required by Hong Kong customs.

• Can Cialis be safely taken after a meal?
  Food has minimal impact on the absorption of tadalafil, so the medication may be taken with or without meals. High‑fat meals might modestly delay onset, but the overall efficacy remains unaffected.

• How quickly does Cialis start working, and how long does the effect last?
  On‑demand dosing typically produces an erection‑facilitating effect within 30 minutes, with a therapeutic window extending up to 36 hours. Daily dosing maintains steady plasma levels, allowing spontaneous sexual activity without planning around dosing time.

• Does Cialis interact with over‑the‑counter supplements such as ginkgo biloba or L‑arginine?
  Certain supplements, especially those with vasodilatory properties (e.g., ginkgo biloba, yohimbine), may potentiate the blood‑pressure–lowering effect of tadalafil. Patients should discuss all supplements with their healthcare provider to avoid unintended hypotension.

• What is the prescription process for ordering Cialis through our online pharmacy?

• Can Cialis be used for sexual activity with a partner of any gender?
  Tadalafil facilitates the physiological process of erection regardless of the gender of the sexual partner. The medication is indicated for men with erectile dysfunction, and its efficacy is independent of the partner’s gender identity.

• Are there any special considerations for patients with liver disease?
  Severe hepatic impairment (Child‑Pugh class C) can increase tadalafil exposure, raising the risk of adverse effects. In such cases, dose reduction to 5 mg or avoidance is recommended, and therapy should be initiated only under close medical supervision.
