Dosage of Tadalafil: An Introduction
The dosage of
tadalafil (
Cialis®) your healthcare provider recommends will vary depending on a number of factors, such as:
- Other medical conditions you may have
- Other medications you may be currently taking.
As always, do not adjust your dosage unless your healthcare provider specifically instructs you to do so.
Tadalafil Dosing for Erectile Dysfunction
The recommended starting dosage of tadalafil for treating
erectile dysfunction is tadalafil 10 mg one hour prior to sexual activity. However, you may take tadalafil anywhere from 1 hour to 36 hours before sexual activity. Depending on the effectiveness of the medication (and whether you experience any side effects), your healthcare provider may increase or decrease your tadalafil dosage. The maximum tadalafil dosage is tadalafil 20 mg.
Alternatively, tadalafil can be taken on a daily basis (every single day, whether you plan sexual activity or not). For this use, the recommended dose is tadalafil 2.5 mg once daily, at the same time each day (it does not matter when you plan to have sexual activity if you take tadalafil this way). If the 2.5 mg daily dosage does not seem to be working well enough, your healthcare provider may increase the dose to tadalafil 5 mg every day.
Dosage of Tadalafil for People With Kidney or Liver Disease
For people with moderate kidney disease, the recommended starting dosage is tadalafil 5 mg. You should not take more than 10 mg in any 48-hour period. For people with severe kidney disease, the maximum recommended daily dosage is tadalafil 5 mg in any 72-hour period.
The maximum dosage for people with mild or moderate liver disease is tadalafil 10 mg once a day. People with severe liver disease should not take tadalafil.
