Dihydrocodeine for pain relief

About dihydrocodeine

Dihydrocodeine is an opioid medicine (sometimes called an opiate). It is used to treat moderate-to-severe types of pain. It works by binding to certain tiny areas, called opioid receptors, in your central nervous system (brain and spinal cord). This leads to a decrease in the way you feel pain and your reaction to pain. Dihydrocodeine is available on a prescription from a doctor.

Dihydrocodeine is sometimes prescribed in combination with the painkiller paracetamol in a medicine called co-dydramol. Co-dydramol is available on prescription and also from pharmacies on the advice of a pharmacist.

Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start taking dihydrocodeine, it is important that your doctor knows:

• Om du är gravid eller ammar.

• If you have a problem with the way your liver works, or a problem with the way your kidneys work.

• Om du har prostataproblem eller några svårigheter med att kissa.

• Om du har några andningsproblem, såsom astma eller kroniskt obstruktiv lungsjukdom (KOL).

• If you have been told you have low blood pressure.

• If you have any problems with your thyroid gland or adrenal glands.

• If you have epilepsy.

• If you have a problem with your bile duct or pancreas.

• Om du har varit förstoppad i mer än en vecka eller har ett inflammatoriskt tarmproblem.

• Om du har ett tillstånd som orsakar muskelsvaghet, kallat myasthenia gravis.

• Om du nyligen har haft en allvarlig huvudskada.

• Om du någonsin har varit beroende av droger eller alkohol.

• Om du någonsin har haft en allergisk reaktion mot en medicin.

• Om du tar några andra läkemedel. Detta inkluderar alla läkemedel du tar som finns att köpa utan recept, samt växtbaserade och komplementära läkemedel.

• Before you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about dihydrocodeine and will provide you with a full list of the side-effects which you may experience from taking it.

• Take dihydrocodeine exactly as your doctor tells you to. There are several different strengths of tablet available, so your doctor or pharmacist will tell you how often you should take your doses. As a guide, 30 mg tablets are usually taken every 4-6 hours as needed and prolonged-release tablets (DHC Continus® brand) are taken every 12 hours. The directions for taking the tablets will be printed on the label of the pack to remind you about what the doctor said to you.

• Swallow the tablets with a drink of water. Dihydrocodeine should preferably to taken after food, as this can help prevent feelings of sickness which can sometimes occur with the first few doses.

• If you have been given tablets called DHC Continus®, these are specially formulated to release dihydrocodeine slowly to give you a more even painkilling effect throughout the day. It is important that you swallow the tablets whole (do not chew or crush them), otherwise the medicine will be released into your bloodstream too quickly and cause problems.

• If you have been given dihydrocodeine liquid medicine for your child, check the label carefully to make sure you are giving the correct dose.

• If you forget to take a dose, take it as soon as you remember and then continue taking your doses as before. Do not take two doses together to make up for a forgotten dose.

• You should not drink alcohol while you are taking dihydrocodeine. This is because dihydrocodeine will increase the risk that you experience side-effects from the alcohol, such as feeling dizzy and sleepy.

• If you are a driver, please be aware that dihydrocodeine is likely to affect your reactions and ability to drive. It is an offence to drive while your reactions are impaired. Even if your driving ability is not impaired, you are advised to carry with you some evidence that the medicine has been prescribed for you - a repeat prescription form or a patient information leaflet from the pack is generally considered suitable.

• You will not be given dihydrocodeine for longer than is necessary. This is because when you take dihydrocodeine repeatedly over a period of time and then stop taking it, it can cause withdrawal symptoms such as making you feel restless or irritable. If you have been taking it for some time and want to stop it, your doctor will recommend that you reduce your dose slowly in order to avoid the risk of these effects.

• Dihydrocodeine is normally prescribed for short periods of pain. If you take it over a longer period of time, your body can become used to it and it will not work as well. This is called tolerance.

• If you are having an operation or dental treatment, tell the person carrying out the treatment that you are taking dihydrocodeine.

• If you buy any medicines, check with a pharmacist that they are safe to take with an opioid painkiller.

Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them. The table below contains some of the most common ones associated with dihydrocodeine. You will find a full list in the manufacturer's information leaflet supplied with your medicine. The unwanted effects often improve as your body adjusts to the new medicine, but speak with your doctor or pharmacist if any of the following continue or become troublesome.

If you experience other symptoms which you think may be due to dihydrocodeine, speak with your doctor or pharmacist for further advice.
