How Does Dihydrocodeine Work?

Dihydrocodeine is a semi-synthetic form of opioid pain relief. It works by blocking the signals that are sent from the area of pain to the brain. This means that your sensation of the pain is either reduced or eliminated.

Dihydrocodeine does not treat the cause of the pain, but it may help you to feel more comfortable whilst recovering from an injury or operation.

Minimising pain is helpful for recovery. If you are able to mobilise then your risk of a post-operative blood clot will be reduced. You may also be able to cough more comfortably to prevent a chest infection after an operation.

How is Dihydrocodeine Taken?
