Tadalafil vs Sildenafil? A Complete Comparison of ED Treatment

Erectile dysfunction (ED) affects millions of men worldwide, and two of the most popular treatments are Tadalafil Vs Sildenafil. While both medications belong to the same class of drugs—PDE5 inhibitors—they have unique characteristics that can influence which is best for you. This guide breaks down their differences, similarities, pros, and cons so you can make an informed choice.

1. What Are Tadalafil and Sildenafil?

Sildenafil is best known by its brand name, Viagra. It was the first oral ED drug approved by the FDA in 1998 and has helped millions of men improve their sexual performance.

Tadalafil, on the other hand, is the generic version of Cialis. It was approved later but quickly became a favorite for its longer-lasting effects.

Mechanism of Action

Both drugs work by increasing blood flow to the penis during sexual stimulation. They inhibit the enzyme phosphodiesterase type 5 (PDE5), which regulates blood flow. This helps relax blood vessels and allows more blood to flow into the penis, making it easier to achieve and maintain an erection.

2. Key Differences Between Tadalafil and Sildenafil

2.1 Dosage and Administration

2.1.1 Tadalafil Dosage

• As needed: 10 mg before sex (range: 5–20 mg)
• Daily: 2.5–5 mg once daily, regardless of sexual activity
• Can be taken with or without food

2.1.2 Sildenafil Dosage

• As needed: Usually 50 mg, 30–60 minutes before sex
• Can be adjusted between 25 mg and 100 mg
• Should be taken on an empty stomach for best results

3. Effectiveness: Which One Works Better?

Both medications are highly effective, with success rates ranging between 70% and 85%. However, individual response can vary.

3.1 Tadalafil: Pros
