The dose will depend on the severity of your pain and your previous history of needing painkillers.
A patient with severe pain should start with an oral dose of one or two 10 mg tablets every 4 hours.

Your doctor will decide the number of tablets you should take.
A reduction in the normal adult dose is recommended.
Not recommended in children under 5 years.
In children from 5 to 12 years: 10 mg every 4 hours.
