Cialis Dosage

For most people, the recommended starting dose of Cialis is 10 mg one hour prior to sexual activity. The maximum recommended dose is Cialis 20 mg. The Cialis dosage your healthcare provider recommends will depend on your age, any medical conditions you may have, and any medications you may be currently taking, among other factors. For Cialis to work properly, you must take it exactly as prescribed.

 

An Introduction to Cialis Dosage

The dose of Cialis® (tadalafil) your healthcare provider recommends will vary depending on a number of factors, including:
 
  • 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.
 

Cialis Dosage for Erectile Dysfunction

The recommended starting dosage of Cialis for treating erectile dysfunction is Cialis 10 mg one hour prior to sexual activity. However, you may take Cialis anywhere from 1 hour to 36 hours before sexual activity. Depending on how well it works and whether you experience any side effects, your healthcare provider may increase or decrease your Cialis dosage. The maximum Cialis dosage is Cialis 20 mg.
 
Alternatively, Cialis can be taken on a daily basis (every single day, whether you plan sexual activity or not). For this use, the recommended dose is Cialis 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 Cialis 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 Cialis 5 mg every day.
 

Cialis Dosage in People With Kidney or Liver Disease

For people with moderate kidney disease, the recommended starting Cialis dosage is 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 Cialis 5 mg in any 72-hour period.
 
The maximum Cialis dosage for people with mild or moderate liver disease is 10 mg once a day. People with severe liver disease should not take Cialis.
