The name of your medicine is Co-dydramol Tablets (called co-dydramol throughout this leaflet). This medicine has been prescribed for you for the relief of mild to moderate pain. Co-dydramol contains two different medicines called paracetamol and dihydrocodeine. Dihydrocodeine belongs to a class of medicines called opioids, which are ‘pain relievers’. This medicine has been prescribed to you and should not be given to anyone else. Opioids can cause addiction and you may get withdrawal symptoms if you stop taking it suddenly. Your prescriber should have explained how long you will be taking it for and when it is appropriate to stop, how to do this safely.
- Do not take for longer than your doctor tells you to.
- This medicine contains paracetamol. Do not take anything else containing paracetamol while taking this medicine.
- Taking a painkiller for headaches too often or for too long can make them worse.
Taking this medicine regularly, particularly for a long time, can lead to addiction. Your prescriber should have explained how long you will be taking it for and when it is appropriate to stop, how to do this safely.
Rarely, increasing the dose of this medicine can make you more sensitive to pain. If this happens, you need to speak to your prescriber about your treatment.
Addiction can cause withdrawal symptoms when you stop taking this medicine. Withdrawal symptoms can include restlessness, difficulty sleeping, irritability, agitation, anxiety, feeling your heartbeat (palpitations), increased blood pressure, feeling or being sick, diarrhoea, loss of appetite, shaking, shivering or sweating. Your prescriber will discuss with you how to gradually reduce your dose before stopping the medicine. It is important that you do not stop taking the medicine suddenly as you will be more likely to experience withdrawal symptoms.
Opioids should only be used by those they are prescribed for. Do not give your medicine to anyone else. Taking higher doses or more frequent doses of opioid, may increase the risk of addiction. Overuse and misuse can lead to overdose and/or death.
Do not take co-dydramol and tell your doctor if:
- You are taking medicines to treat depression called MAOIs (monoamine oxidase inhibitors) or have taken them in the last 2 weeks. MAOIs are medicines such as moclobemide, phenelzine, tranylcypromine.
- You are allergic to the active substances or any of the other ingredients in your medicine (listed in Section 6).
Signs of an allergic reaction include a rash and breathing problems. There can also be swelling of the legs, arms, face, throat or tongue. - You have breathing problems.
- You are having an asthma attack.
- You have liver disease.
- You are an alcoholic.
Do not take co-dydramol if any of the above apply to you. If you are not sure, talk to your doctor or pharmacist before taking co-dydramol.
Co-dydramol must not be given to children under 12 years of age.
- You are or have ever been addicted to opioids, alcohol, prescription medicines, or illegal drugs.
- You have previously suffered from withdrawal symptoms such as agitation, anxiety, shaking or sweating, when you have stopped taking alcohol or drugs.
- You feel you need to take more co-dydramol to get the same level of pain relief, this may mean you are becoming tolerant to the effects of this medicine or are becoming addicted to it. Speak to your prescriber who will discuss your treatment and may change your dose or switch you to an alternative pain reliever.
- You have kidney problems.
- You have asthma.
- You have problems with your thyroid gland (hypothyroidism).
- You are in the last three months of pregnancy (see Pregnancy and breast-feeding section).
If you are not sure if any of the above apply to you, talk to your doctor or pharmacist before taking this medicine.
- You have severe illnesses, including severe renal impairment or sepsis (when bacteria and their toxins circulate in the blood leading to organ damage), or you suffer from malnutrition, chronic alcoholism or if you are also taking flucloxacillin (an antibiotic). A serious condition called metabolic acidosis (a blood and fluid abnormality) has been reported in patients in these situations when paracetamol is used at regular doses for a prolonged period or when paracetamol is taken together with flucloxacillin.
Symptoms of metabolic acidosis may include: serious breathing difficulties with deep rapid breathing, drowsiness, feeling sick (nausea) and being sick (vomiting).
Tell your doctor or pharmacist if you are taking or have recently taken any other medicines. This includes medicines obtained without a prescription, including herbal medicines. This is because co-dydramol and some other medicines can affect the way each other work.
Concomitant use of co-dydramol and sedative medicines such as benzodiazepines or related drugs increases the risk of drowsiness, difficulties in breathing (respiratory depression), coma and may be life-threatening. Because of this, concomitant use should only be considered when other treatment options are not possible.
However if your doctor does prescribe co-dydramol together with sedative medicines the dose and duration of concomitant treatment should be limited by your doctor. Please tell your doctor about all sedative medicines you are taking, and follow your doctor’s dose recommendation closely. It could be helpful to inform friends or relatives to be aware of the signs and symptoms stated above. Contact your doctor when experiencing such symptoms.
Tell your doctor or pharmacist if you are taking any of the following medicines, or have taken them in the past two weeks:
- Medicines which make you drowsy or sleepy (CNS depressants or a benzodiazepine) such as sleeping tablets, sedatives, tranquilisers, hypnotics and medicines used to treat anxiety or anaesthetics.
- Antidepressant medicines such as imipramine, amitriptyline, tranylcypromine, dosulepin, mirtazapine or chlorpromazine.
Tell your doctor or pharmacist if you are taking:
- Flucloxacillin (antibiotic), due to a serious risk of blood and fluid abnormality (called metabolic acidosis) that must have urgent treatment (see section 2).
Tell your doctor or pharmacist if you are taking any other medicines:
- Medicines used to thin the blood such as warfarin.
- Chloramphenicol – an antibiotic used for infections.
- Medicines used to treat allergies (antihistamines).
- Medicines for travel sickness or nausea (antihistamines or antiemetics).
- Medicines to treat psychiatric disorders (antipsychotics or neuroleptics).
- Muscle relaxants.
- Medicines to treat Parkinson’s disease.
If you are not sure if any of the above applies to you, talk to your doctor or pharmacist before taking co-dydramol.
You should not drink alcohol while you are taking these tablets.
- Do not take co-dydramol if you are pregnant or think you might be pregnant unless you have discussed this with your prescriber and the benefits of treatment are considered to outweigh the potential harm to the baby. If necessary, co-dydramol can be used during pregnancy. You should use the lowest possible dose that reduces your pain and/or your fever and use it for the shortest time possible. Contact your doctor or midwife if the pain and/or fever are not reduced or if you need to take the medicine more often.
- If you use co-dydramol during pregnancy, your baby may become dependent and experience withdrawal symptoms after the birth which may need to be treated.
- Do not take co-dydramol while you are breastfeeding as dihydrocodeine passes into breast milk and will affect your baby.
