What is Cialis Black (Tadalafil)?
Cialis Black contains tadalafil, a phosphodiesterase type 5 (PDE5) inhibitor that works by relaxing blood vessels, increasing blood flow to the penis during sexual stimulation. The "Black" version is marketed to emphasize a more potent effect or larger dosage, helping to maintain an erection for up to 36 hours, often dubbed the "weekend pill." It requires sexual arousal to be effective and is prescribed for erectile dysfunction (ED).
Dosage of Cialis Black (Tadalafil)
- Standard doses range from 10 mg to 20 mg taken as needed.
- Take the pill at least 30 minutes before sexual activity.
- The maximum recommended dose is 20 mg once per day.
- Lower doses (2.5 mg or 5 mg) may be prescribed daily for continuous ED and benign prostatic hyperplasia (BPH) treatment.
- Dosage adjustments may be needed for kidney or liver impairment.
Take 10–20 mg before sex, not exceeding one dose per day; daily lower doses are available for ongoing treatment.
