Cialis: Comprehensive Guide to tadalafil use, benefits, and expert advice

What Is Cialis? — Tadalafil Explained

Cialis, known generically as tadalafil, is a prescription medication clinically proven to treat erectile dysfunction (ED) and benign prostatic hyperplasia (BPH). Developed by Eli Lilly, it has revolutionized male sexual health since its FDA approval in 2003. Cialis belongs to a class of drugs called PDE5 inhibitors, which also includes sildenafil (Viagra) and vardenafil (Levitra). However, Cialis stands out for its long-lasting effects—up to 36 hours—earning it the nickname “The Weekend Pill.”

• Active Ingredient: Tadalafil
• Common Dosages: 2.5mg, 5mg, 10mg, 20mg
• Primary Uses: Erectile dysfunction, benign prostatic hyperplasia
• Onset: 30–60 minutes
• Duration: Up to 36 hours

“Cialis is now one of the first-line treatments for erectile dysfunction due to its efficacy and patient-friendly dosing options,” notes Dr. Amanda Reese, MD, a board-certified urologist.

How Does Cialis Work? Mechanism of Action

Tadalafil (Cialis) blocks the enzyme phosphodiesterase type 5 (PDE5), which results in increased blood flow to the penis during sexual stimulation. This improved blood flow helps men achieve and maintain a firm erection.

Infographic: How Cialis Works

• Sexual stimulation triggers nitric oxide release
• Nitric oxide increases cGMP levels
• PDE5 normally breaks down cGMP
• Tadalafil inhibits PDE5 —> Sustained cGMP —> Smooth muscle relaxation —> Increased blood flow —> Stronger erection

Indications: Who Should Consider Taking Cialis?

Cialis is FDA approved for:

• Erectile Dysfunction (ED): Difficulty in achieving or maintaining an erection sufficient for sex.
• Benign Prostatic Hyperplasia (BPH): Enlarged prostate symptoms such as difficulty urinating.
• Dual Indication: Some men suffer both ED and BPH, and tadalafil can target both issues with a single pill.

Less Common Uses

Cialis is sometimes prescribed off-label for pulmonary arterial hypertension (under the brand name Adcirca).

How to Use Cialis: Dosage and Administration

Always consult a healthcare provider before starting Cialis. Your doctor will tailor the dose to your individual health status and response.

• ED On-Demand: 10mg, taken about 30 minutes before anticipated sexual activity. May be adjusted between 5mg and 20mg.
• ED Daily Use: 2.5mg or 5mg, taken at the same time every day, regardless of sexual activity.
• BPH or ED+BPH: 5mg once daily.

Tips for Best Results

• Take with or without food.
• Do not take more than one dose per day.
• Sexual stimulation is required for efficacy—Cialis is not an aphrodisiac.
• If you miss a daily dose, take it as soon as you remember, but skip it if it’s almost time for the next dose.

“Starting with the lowest effective dose minimizes side effects. Most men respond well to 10mg as needed or 5mg daily,” says Dr. Paul Lin, PharmD.
