Sold under the brand name Cialis, Tadalafil is known for its long duration of action — lasting up to 36 hours, making it a popular option for more spontaneous activity compared to other ED medications.

Erectile dysfunction (ED)
Benign prostatic hyperplasia (BPH)
Combined ED and BPH symptoms
Pulmonary arterial hypertension (under brand Adcirca)

Common questions about Tadalafil

Tadalafil can last up to 36 hours. It usually starts working within 30–60 minutes.

Yes, you can take a low-dose Tadalafil (usually 2.5 mg or 5 mg) every day if prescribed by your doctor. This allows for more spontaneous sexual activity, rather than timing a dose before intercourse.

Tadalafil lasts much longer than Sildenafil (up to 36 hours vs. 4–6 hours) and can be taken daily. Sildenafil works faster for some, but Tadalafil offers more flexibility. The better option depends on your needs and how your body responds.

If Tadalafil doesn’t work, make sure you’ve taken it correctly—on an empty stomach and with enough time (30–60 minutes before activity). If it still doesn’t help after a few tries, talk to your doctor. A different dose or medication may be more effective.

Tadalafil is not approved for use in women. Its safety and effectiveness haven't been fully studied in females, so it should only be used if specifically prescribed by a doctor for off-label purposes.
