What is Tadalafil?

Tadalafil is the active ingredient in Cialis, one of the most well-known treatments for erectile dysfunction. It was developed by Eli Lilly and has been used medically since the early 2000s. It's also prescribed for pulmonary arterial hypertension and benign prostatic hyperplasia.

Quick Facts

How Does It Work?

Tadalafil is a PDE5 inhibitor. It works by relaxing the smooth muscle in blood vessel walls, which increases blood flow to specific areas of the body. When sexual stimulation occurs, this improved blood flow makes it easier to achieve and maintain an erection.

What It's Used For

• Treating erectile dysfunction in men
• Managing symptoms of benign prostatic hyperplasia (enlarged prostate)
• Treating pulmonary arterial hypertension to improve exercise capacity

What to Expect

Tadalafil typically starts working within 30 minutes of taking it. Because of its long half-life, its effects can last up to 36 hours, earning it the nickname "the weekend pill." You still need sexual stimulation for it to work — it doesn't cause an automatic response.

Possible Side Effects

• Headache and facial flushing
• Indigestion or back pain
• Nasal congestion or runny nose

Cycle & Dosage Notes

For on-demand use, take one 20mg tablet at least 30 minutes before sexual activity. Do not take more than one dose in a 24-hour period. Tadalafil is not a hormonal compound, so no PCT is required.

Storage

Keep at room temperature (15–25°C), away from light and moisture. Leave in the original packaging.
