Frequently Asked Questions
Q1: How long does Cialis 20mg Tablet work?
Cialis 20mg (tadalafil) is renowned for its exceptionally long duration of up to 36 hours, earning it the nickname 'the weekend pill'. Take only once per day.
Q2: Is Cialis 20mg Tablet safe for everyone?
Not recommended for those with heart conditions, low blood pressure, or taking nitrates. Consult your doctor before use.
Q3: Can Cialis 20mg Tablet be combined with alcohol?
Alcohol may reduce effectiveness and increase side effects. It's best to avoid or limit consumption.
Q4: What is Cialis 20mg used for?
Cialis 20mg contains tadalafil 20mg and is a brand-name PDE5 inhibitor for treating erectile dysfunction. Unlike generic tadalafil, Cialis is manufactured by Eli Lilly and is the original branded product known for its 36-hour duration.
Q5: How does Cialis 20mg differ from Viagra?
Cialis (tadalafil) and Viagra (sildenafil) are both PDE5 inhibitors but differ in duration. Cialis lasts up to 36 hours, compared to Viagra's 4-6 hours. Tadalafil also has a more consistent effect regardless of food intake.
Q6: How long does Cialis 20mg take to work?
Cialis 20mg typically begins working within 30 to 45 minutes. Some men may notice effects as early as 15 minutes. Unlike sildenafil, food does not significantly delay its absorption.
Q7: Why is Cialis called the 'weekend pill'?
One tablet of Cialis 20mg taken on a Friday evening can remain effective throughout Saturday and Sunday, allowing for multiple spontaneous sexual encounters over a weekend without the need for additional dosing.
Q8: Can Cialis 20mg be taken with food?
Yes, Cialis 20mg can be taken with or without food. High-fat meals do not significantly delay its onset, which is a notable advantage over sildenafil-based medications.
Q9: What side effects are associated with Cialis 20mg?
Common side effects of Cialis include headache, back pain, muscle aches, nasal congestion, indigestion, and facial flushing. Back pain and muscle aches are more characteristic of tadalafil and usually resolve within 2 days.
Q10: Who should not take Cialis 20mg?
Cialis 20mg is contraindicated for men taking nitrate medications, those with severe cardiovascular disease, recent heart attack or stroke, uncontrolled hypotension or hypertension, or severe hepatic impairment.
Q11: Can Cialis 20mg treat benign prostatic hyperplasia (BPH)?
Yes, tadalafil is approved for treating both ED and symptoms of BPH (enlarged prostate), such as urinary urgency and weak urine flow. Low daily doses (2.5-5mg) are also approved for this purpose.
