Tadalafil

What Are Tadalafil? 

Tadalafil is the active ingredient in Cialis — the world’s longest-acting PDE5 inhibitor and the most popular ED treatment for men who value spontaneity. Unlike Sildenafil’s 4–6 hour window, Tadalafil provides up to 36 hours of erectile readiness, earning it the nickname ‘the weekend pill.’ At a once-daily dose of 5 mg, Tadalafil also provides continuous all-day erectile readiness and treats BPH lower urinary tract symptoms. AmozonPill stocks 54 generic Tadalafil products across all dose strengths — sourced from FDA-inspected, WHO-GMP manufacturers at up to 95% below Cialis brand price.

How to Choose the Right Product

For occasional use and spontaneous sex: Tadalafil 20 mg taken 30 minutes before activity — the 36-hour window means one tablet covers a full weekend. For frequent sexual activity or maximum convenience: Tadalafil 5 mg once daily eliminates planning entirely. For men with both ED and BPH urinary symptoms: Tadalafil 5 mg daily is the only medication approved for both conditions in a single dose. For first-time users: start with Tadalafil 10 mg to assess response and tolerability before escalating to 20 mg. 

Frequently Asked Questions

Why is Tadalafil called ‘the weekend pill’? 

Tadalafil’s 36-hour duration of action means a single Friday-evening dose provides erectile readiness throughout an entire weekend — covering spontaneous sexual activity without the need to time dosing. No other PDE5 inhibitor offers this duration. 

What is the difference between Tadalafil 20 mg and Tadalafil 5 mg daily? 

Tadalafil 20 mg is taken on-demand (before anticipated sexual activity) — it provides a single 36-hour window per tablet. Tadalafil 5 mg daily builds to a steady-state plasma level over 5 days, providing 24-hour continuous erectile readiness every day. Daily dosing is preferred by men who have sex frequently or who prefer to remove the planning aspect entirely. 

Is Tadalafil affected by food? 

No — this is a key advantage over Sildenafil. Tadalafil can be taken with or without food, including high-fat meals, without affecting its absorption or onset of action. Moderate alcohol (up to 2 units) also does not significantly reduce efficacy. 

What is the difference between Vidalista and Cialis? 

Vidalista is manufactured by Centurion Laboratories (India) and contains Tadalafil — the same active ingredient as Cialis. Vidalista meets WHO-GMP manufacturing standards. The pharmacological action is identical to Cialis. The price of Vidalista is 90%+ lower than branded Cialis. 

Can Tadalafil help with enlarged prostate symptoms? 

Yes. Tadalafil 5 mg once daily is FDA-approved for benign prostatic hyperplasia (BPH) — it relaxes smooth muscle in the prostate and bladder neck, improving urinary flow and reducing LUTS. It is the only medication that treats both ED and BPH simultaneously in a single daily dose. 

What side effects does Tadalafil cause? 

The most common side effects are headache (11%), indigestion (10%), back pain (6%), and muscle aches (5%) — the latter two are unique to Tadalafil and related to PDE11 inhibition. They typically resolve within 48 hours. Flushing and nasal congestion are less common than with Sildenafil.
