How does tadalafil work?
Tadalafil relaxes blood vessels, improving circulation to help with erectile dysfunction, reduce urinary symptoms in BPH, and lower blood pressure in pulmonary hypertension.
What is tadalafil used to treat?
Tadalafil is commonly prescribed for:
- Erectile dysfunction (ED) (to improve the ability to get and maintain an erection)
- Benign prostatic hyperplasia (BPH) (to reduce urinary symptoms such as difficulty urinating)
- Pulmonary arterial hypertension (PAH) (to lower blood pressure in the lungs)
Who can take tadalafil?
Tadalafil is suitable for most adults, but your doctor will assess if it’s right for you.
Who might not be able to take tadalafil?
Tadalafil may not be suitable if you:
- Have heart disease or a history of stroke
- Have low blood pressure or uncontrolled high blood pressure
- Are taking nitrates for chest pain
- Have severe kidney or liver disease
Can I take tadalafil if I’m pregnant or breastfeeding?
Tadalafil is not prescribed for women unless treating pulmonary hypertension. If you are pregnant or breastfeeding, consult your doctor.
What if I miss a dose?
- For ED as needed: Take only when required, about 30 minutes before sexual activity.
- For daily ED or BPH treatment: If you miss a dose, take it as soon as you remember. If it’s close to your next dose, skip the missed one—do not take two doses at once.
How effective is tadalafil?
Tadalafil is highly effective for ED, working within 30 to 60 minutes and lasting up to 36 hours. For BPH and PAH, it works best when taken regularly.
What should I do if I take too much?
Taking too much tadalafil can cause severe dizziness, fainting, or prolonged erections (priapism). If you experience serious side effects, seek emergency medical help immediately.
What dose of tadalafil is usually taken?
- For erectile dysfunction: 10mg to 20mg as needed, or 2.5mg to 5mg daily
- For BPH: 5mg once daily
- For pulmonary hypertension: 40mg once daily
Your doctor will determine the correct dose based on your condition.
