The recommended starting dose of tadalafil for erectile dysfunction is 10 mg, taken as needed, at least 30 minutes before sexual activity. This dose can be increased to 20 mg or decreased to 5 mg based on individual response and tolerance. However, do not exceed 20 mg in a 24-hour period.
Dosage Adjustments
Your doctor might adjust your dosage based on several factors. For instance, individuals with kidney or liver problems may require a lower dose. Similarly, men taking certain medications, like nitrates, should not use tadalafil at all due to potentially dangerous interactions.
Tadalafil for Benign Prostatic Hyperplasia (BPH)
For BPH, the usual starting dose is 5 mg once daily. This dose is taken consistently, regardless of sexual activity. Your doctor will determine the appropriate dosage for your specific needs.
Important Considerations
| Kidney problems | Lower dose may be necessary; consult your doctor. |
| Liver problems | Lower dose may be necessary; consult your doctor. |
| Age (over 65) | Your doctor may recommend a lower starting dose. |
| Heart problems | Careful monitoring and a potentially adjusted dose may be necessary; consult your doctor. |
Frequency of Use
For erectile dysfunction, tadalafil is usually taken as needed. For BPH, it’s taken daily. Never exceed the prescribed dose, and always follow your doctor’s instructions precisely.
