Cialis (Tadalafil)

Cialis is a prescription tablet for erectile dysfunction (ED). It helps increase blood flow to the penis during sexual stimulation, so you can get and keep an erection when you need it. Known for its long action window often up to 36 hours Cialis gives you more flexibility and less pressure to time things perfectly. Use exactly as directed by your healthcare provider.

What Cialis Does

• Supports reliable erections during sexual stimulation
• Works on demand with a longer window than many ED pills
• Can be adjusted up (20 mg) or down (5 mg) based on your response

How Tadalafil Works

Tadalafil blocks the PDE5 enzyme in penile blood vessels. That relaxes smooth muscle and lets more blood flow in when you’re aroused. It won’t cause arousal by itself you still need sexual stimulation.

How And When To Take It

• Take one tablet about 30 minutes before sexual activity
• Swallow whole with water; don’t crush or split unless your pharmacist says it’s okay
• Do not take more than one dose in 24 hours
• If 10 mg feels too strong or too weak, ask your provider about adjusting to 5 mg or 20 mg, or a daily 2.5–5 mg plan

Food, Alcohol, And Timing Tips

• Food: You can take Cialis with or without food; fatty meals have minimal impact
• Alcohol: Keep it light—too much can lower blood pressure and affect performance
• Duration: Many men notice improved responsiveness for up to 36 hours (not a continuous erection)

Choosing Your Best Dose
