Other medicines and CODEP XR
Always tell your healthcare professional if you are taking any other medicine (This includes complementary or traditional medicines). If you take CODEP XR with other medicines, the effect of CODEP XR or the other medicines may be changed. Medicines or substances, which have effects on the central nervous system (CNS) (CNS depressant effects), e.g. alcohol, other opioid class medicines (strong pain medicines), medicines to help you sleep, antidepressants, mood stabilising medication, anti-histamines (medicines for allergies or travel sickness) and anti-emetics (medicines to stop you from vomiting) may increase the effect of CODEP XR on your breathing ability. If you are taking CODEP XR with medicines which decrease the blood’s clotting ability (warfarin), your blood clotting time may be faster or slower. If you are taking CODEP XR with medicines known as anticholinergics or medications with anticholinergic activity (examples include tricyclic antidepressants, antihistamines, antipsychotics, muscle relaxants, anti-Parkinson medicines), it may increase the side effects of these medicines. Tell your doctor or pharmacist:
- if you are taking antibiotics (such as clarithromycin)
- if you are taking antifungal medicines (such as ketoconazole)
- if you are taking medicine to treat HIV (such as ritonavir)
- if you are taking medicine to treat tuberculosis (such as rifampicin)
- if you are taking medicine to treat epilepsy (such as carbamazepine or phenytoin)
- if you are taking medicine to treat depression (such as paroxetine or St.John’s Wort)
- if you are taking quinidine (a medicine to treat a fast heart beat).
Grapefruit juice may also increase the blood levels of oxycodone and should not be drunk whilst taking CODEP XR.
CODEP XR with food and drink
You can take CODEP XR with or without food. Drinking alcohol during your treatment with CODEP XR may make you sleepy or increase the risk of serious side effects, such as shallow breathing with the risk to stopping breathing, and loss of consciousness. It is recommended not to drink alcohol while you are taking CODEP XR.
Pregnancy and breastfeeding
If you are pregnant or breastfeeding, think you may be pregnant or are planning to have a baby, please consult your doctor, pharmacist or other healthcare professional for advice before taking CODEP XR. CODEP XR is not recommended for use in pregnancy or during labour. Both oxycodone and naloxone pass into the placenta. Use of CODEP XR tablets during pregnancy should be avoided. If used over prolonged periods during pregnancy, oxycodone may lead to withdrawal symptoms in the newborn baby. If oxycodone is given during childbirth, the baby may have breathing problems (respiratory depression).
Breastfeeding should be discontinued during treatment with CODEP XR.
Driving and using machines
CODEP XR may reduce your ability to drive and use machines safely. It is not always possible to predict to what extent CODEP XR may interfere with the daily activities of a patient. Patients should ensure that they do not engage in the above activities until they are aware of the measure to which CODEP XR affects them.
