Tadalafil 10 mg tablets are a medium‑strength, “as‑needed” option for erectile dysfunction widely used by adult men in the USA. This dose is a common starting point when men want flexible, on‑demand support without jumping straight to the highest 20 mg strength.​

Tadalafil 10 mg overview
Tadalafil 10 mg is a PDE5 inhibitor that relaxes blood vessels and increases blood flow to the penis, helping men achieve and maintain an erection with sexual stimulation. In U.S. practice it is typically prescribed as an on‑demand ED tablet and is equivalent in strength to branded Cialis 10 mg.​

How 10 mg is usually taken
For most adults, the usual on‑demand starting dose is one tadalafil 10 mg tablet taken at least 30 minutes before planned sexual activity. Depending on response and side effects, a prescriber may adjust the dose down to 5 mg or up to 20 mg, but it must not be taken more than once in 24 hours.​

Benefits of tadalafil 10 mg
Balanced strength: 10 mg offers stronger erection support than low daily doses, but with a lower side‑effect risk than jumping straight to 20 mg for many men.​

Long duration: A single 10 mg tablet can work for up to 36 hours, giving a wide window for natural, spontaneous intimacy.​

Flexible option: Suited for men who do not need daily ED treatment but want effective on‑demand support a few times per week or less.​

Side effects and precautions
Typical side effects include headache, flushing, indigestion, nasal congestion, back pain, and dizziness, which are usually mild and temporary. Tadalafil 10 mg must be avoided with nitrates and certain heart or blood‑pressure medicines, and men with serious heart, liver, or kidney problems should seek medical advice from a U.S. provider before use
