Tadalafil: Everything You Need to Know About This Popular Treatment

What is Tadalafil? Mechanism of Action Explained

Tadalafil is a widely prescribed medication recognized for its efficacy in treating erectile dysfunction (ED) and benign prostatic hyperplasia (BPH). Marketed under the brand name Cialis, and also available as a generic, Tadalafil stands out due to its longer duration of action compared to sildenafil (Viagra) and vardenafil (Levitra).

But what makes Tadalafil unique? Primarily, it is a phosphodiesterase type 5 (PDE5) inhibitor. This means it enhances erectile function by increasing blood flow to the penis in response to sexual stimulation. The increased blood flow is possible because Tadalafil relaxes the smooth muscle in the blood vessels of the penis, facilitating easier and longer-lasting erections. [Source: Mayo Clinic, NIH]

How Long Does Tadalafil Last?

Tadalafil is often called the “weekend pill” due to its long duration—up to 36 hours in the body, offering a more relaxed approach to intimacy compared to the 4-6 hours of sildenafil. This extended window allows for greater spontaneity, a feature highly praised in patient feedback.

Like any medication, Tadalafil can cause side effects. Most are mild and transient, but some require immediate medical attention.

Common Side Effects: Headache, indigestion, back pain, muscle aches, nasal congestion, flushing.
Less Common/Rare But Serious: Sudden vision or hearing loss, priapism (erection lasting more than 4 hours), chest pain, allergic reactions (rash, swelling, difficulty breathing).
