- Treats erectile dysfunction (ED) – helps achieve and maintain a
strong erection with sexual stimulation
- Works for up to 36 hours – known as the “weekend pill” for longer
duration than sildenafil
- Treats benign prostatic hyperplasia (BPH) – relieves symptoms like
frequent urination, weak stream, and urgency
- Approved for both ED and BPH together (daily low-dose use
improves symptoms of both)
- Improves blood flow to the penis and relaxes prostate/bladder
muscles
- Daily low-dose option (2.5–5 mg) allows spontaneous sex without
timing the pill
- Also used for pulmonary arterial hypertension (under brand Adcirca)
Precautions
Never combine with nitrates (nitroglycerin, poppers) or riociguat – can cause
life-threatening blood pressure drop.
Seek emergency help if erection lasts longer than 4 hours (priapism), or you get
sudden vision/hearing loss or chest pain.
Consult your doctor first if you have heart disease, low blood pressure,
liver/kidney issues, retinal disorders, or history of priapism.
