- Benign Prostatic Hyperplasia (BPH): It can also help relieve symptoms of benign prostatic hyperplasia, such as difficulty urinating or frequent urination.
- Pulmonary Arterial Hypertension (PAH): Tadalafil is prescribed for pulmonary arterial hypertension to improve exercise capacity and reduce symptoms associated with high blood pressure in the lungs.

- Daily Use: A lower dose of 2.5mg to 5mg can be taken daily, regardless of sexual activity.
