What does it do?

Dihydrocodeine is used to relieve pain.

How should you take it?

Take dihydrocodeine as directed with a glass of water. You can take it with or without food. Swallow whole - do not crush or chew.

What if you forget a dose?

If dihydrocodeine is taken regularly and it is nearly time for your next dose, skip the missed dose and take your next dose at the usual time. Otherwise, take the missed dose as soon as you remember. Do not take two doses at the same time.
