Tadalafil: Uses, Dosage, Benefits, Side Effects, and Complete Safety Guide
What Is Tadalafil?
Drug Classification and Overview
Tadalafil belongs to a group of medicines called PDE5 inhibitors. These medications improve blood flow in certain parts of the body.
How It Became Popular Worldwide
It gained popularity because of its long-lasting effect — up to 36 hours. That’s why some people call it “the weekend pill.”
Why It Is Prescribed
Doctors prescribe tadalafil for:
- Erectile Dysfunction (ED)
- Benign Prostatic Hyperplasia (BPH)
- Pulmonary Arterial Hypertension (PAH)
How Tadalafil Works in the Body
Understanding Blood Flow and Erections
An erection depends on proper blood flow. When blood vessels relax and widen, blood flows more easily.
PDE5 Inhibitors Explained
Tadalafil blocks the enzyme PDE5. This helps relax blood vessels and improves circulation where needed.
Duration of Action
Unlike some similar medications that last 4–6 hours, tadalafil can remain effective for up to 36 hours.
That doesn’t mean constant effect — it means improved responsiveness during that time.
Main Uses of Tadalafil
Erectile Dysfunction (ED)
Helps men achieve and maintain an erection sufficient for sexual activity.
Benign Prostatic Hyperplasia (BPH)
Relieves symptoms like:
- Frequent urination
- Weak urine stream
- Difficulty starting urination
Pulmonary Arterial Hypertension (PAH)
Improves exercise capacity by relaxing blood vessels in the lungs.
Dual Treatment Benefits
Some patients benefit from treatment of both ED and BPH with one medication.
