Cialis is the brand name for Tadalafil, a medication used to treat erectile dysfunction (ED) and benign prostatic hyperplasia (BPH, enlarged prostate).
This drug works by relaxing blood vessels and increasing blood flow to the penis, enabling stronger and longer-lasting erections.
Why Does Cialis Come in Two Dosages?
In Thailand, Cialis (Tadalafil) is commonly prescribed in two strengths:
- Cialis 20mg – Comes in a box of 4 tablets
- Cialis 5mg – Comes in a box of 28 tablets
Both dosages serve different purposes in treating ED and other conditions.
How to Use Cialis (Tadalafil)?
- For Treating Enlarged Prostate (BPH)
- Take 5mg once daily as prescribed by a doctor.
- Continue treatment until symptoms improve.
- For Treating Erectile Dysfunction (ED)
A doctor will assess your condition and recommend the appropriate dosage. There are two common treatment approaches:
On-Demand Use (Cialis 20mg)
- Take 20mg at least 30 minutes before sexual activity.
- The effects can last up to 36 hours, allowing for spontaneous intercourse within this time frame.
Daily Use (Cialis 5mg)
- Take 5mg once daily at the same time each day.
- Allows for spontaneous sexual activity at any time.
- Ideal for men who prefer a continuous treatment option.
Important Warning: Cialis is a prescription-only medication and should only be taken under a doctor’s supervision.
Beware of counterfeit Cialis sold online!
