Erectile Dysfunction (ED): Helps achieve and maintain an erection by improving blood flow.
Benign Prostatic Hyperplasia (BPH): Relieves urinary symptoms like weak stream or frequent urination.
ED + BPH: Can treat both together.
Pulmonary Arterial Hypertension (PAH): In a different brand/formulation and dose (used to lower lung blood pressure).
How it works
Cialis relaxes blood vessels by inhibiting the enzyme PDE-5, increasing blood flow.
Its effect can last up to 36 hours, which is why it's called the “weekend pill.”
