Tadalafil is a widely prescribed medication used to treat erectile dysfunction (ED) and other medical conditions in adults. It works by increasing blood flow, helping to achieve and maintain an erection when sexually aroused [1].
This medication is available in tablet form and is usually taken once per day. The dosage can vary based on the condition being treated and your doctor’s recommendations.

Tadalafil is primarily known as a treatment for erectile dysfunction, but it is also prescribed for:

• Benign prostatic hyperplasia (BPH) – a condition that causes an enlarged prostate, leading to urinary symptoms.
• Pulmonary arterial hypertension (PAH) – a type of high blood pressure that affects the lungs and heart.

How to take tadalafil

For erectile dysfunction: You may be prescribed a low-dose daily tablet of tadalafil or a higher-dose tablet to take as needed before sexual activity.

How long should you take tadalafil?

The duration of tadalafil treatment depends on the condition being treated and your doctor’s recommendations. It can be a short-term or long-term medication, depending on your individual health needs [3].

Tadalafil for BPH and PAH

If you are taking tadalafil for benign prostatic hyperplasia (BPH) or pulmonary arterial hypertension (PAH), it is usually prescribed as a long-term treatment to manage symptoms effectively.

However, if you are using tadalafil alongside finasteride to treat BPH, you may only need to take tadalafil for up to 26 weeks as part of your treatment plan.
