Dihydrocodeine 30mg

Dihydrocodeine is an opioid painkiller. It’s used to treat moderate to severe pain, such as after an operation or a serious injury.

It’s also used for long-term pain if weaker painkillers, such as paracetamol, ibuprofen and aspirin, have not worked.

It works by blocking pain signals from the central nervous system and the brain.

Dihydrocodeine is only available on prescription.

It comes as standard tablets, slow-release tablets and as a liquid that you swallow. It can also be given by an injection into the muscle or under the skin. This is usually done in hospital.

Co-dydramol, Paramol, Remedeine and Remedeine Forte are brand names that contain dihydrocodeine and paracetamol.

How to take it

If you’re taking dihydrocodeine as a liquid, it will come with a plastic medicine spoon or syringe to help you measure the correct amount. Ask a pharmacist for one if you do not have it.

Do not measure the liquid with a kitchen teaspoon because it will not give the right amount.

How long to take it for

This will depend on why you’re taking dihydrocodeine.

If you’re taking it for pain after an operation you may only need to take if for a short time.

You may need to take it for longer if you have a long-term pain or illness such as cancer.

Always check with a doctor if you want to stop taking dihydrocodeine.

It’s possible that you could become dependent on dihydrocodeine and have withdrawal symptoms if you stop suddenly. These can include:

• yawning
• sneezing
• muscle twitching
• sweating
• feeling worried or anxious
• poor sleep
• pain, including stomach pain
• feeling or being sick
• feeling restless

If these happen to you, speak to a doctor. It may be possible to reduce your dose slowly to stop these from happening.

If you forget to take it

If you forget to take a dose, check the information leaflet inside the packet or ask a pharmacist or doctor for advice on what to do.

Never take 2 doses at the same time to make up for a forgotten one.

If you often forget doses, it may help to set an alarm to remind you. You could also ask a pharmacist for advice on other ways to remember to take your medicine.

If you take too much

• feel very sleepy, sick or dizzy
• find it difficult to breathe
• become unconscious

• store it properly and safely at home
• keep it out of the sight and reach of children
• do not give your medicine to anyone else
• return any unused dihydrocodeine to a pharmacy so they can throw it away in the right way
