Talk to your doctor or pharmacist if you get any of the following symptoms while taking Metadon Nordic Drugs:

Children are more sensitive to methadone than adults. Therefore, poisoning can occur at very low doses. To prevent children from accidentally ingesting methadone when using it at home, keep it in a safe place out of the reach of children.

Other medicines and Methadone Nordic Drugs

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines. Pay special attention to:

• medicines that affect your mental state (eg thioridazine, phenothiazines, haloperidol, and sertindole)

• medicines for heart disease (verapamil, quinidine )

• the type of antidepressant called monoamine oxidase inhibitors ( MAOIs ), especially if you have been taking them for the last two weeks

Other medicines you take may also affect your heart (eg sotalol, amiodarone, and flecainide ).

The risk of side effects is increased if you use methadone at the same time as antidepressants (eg citalopram, duloxetine, escitalopram, fluoxetine, fluvoxamine, paroxetine, sertraline, venlafaxine, amitriptyline, clomipramine, imipramine, and nortriptyline). Contact a doctor if you get symptoms such as:

You must tell your doctor about all the other medicines you are taking, as they may be dangerous if you take them with methadone. In such situations, your doctor may decide that your heart needs to be monitored using an ECG at the beginning of treatment to check that no such effects occur. Methadone can also affect certain blood and urine samples. Tell your doctor that you are taking methadone before leaving any samples.

Methadone Nordic Drugs with food, drink and alcohol

You must not drink alcohol while taking Methadone Nordic Drugs as it can cause serious side effects. Do not drink grapefruit juice when you are being treated with Methadone Nordic Drugs as it may alter the effect of the medicine.

Pregnancy, breastfeeding and fertility

If you are pregnant, think you may be pregnant, or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine. You should not take Methadone Nordic Drugs during labor.

Talk to your doctor if you are breastfeeding or planning to breastfeed while taking methadone as it may affect your baby. Monitor your child for abnormal signs and symptoms such as increased drowsiness (more than usual), difficulty breathing, or muscle weakness; if your doctor decides that you can breastfeed during treatment. Contact a doctor immediately if you notice any of these symptoms.

Driving and using machines

Methadone affects the coordination between brain and body movements so the ability to drive or use machines can be severely affected until your medication has stabilized at a certain dose level. You should therefore not drive or use machines during the initial period of treatment. How long it takes before you can drive a car or use machines are very individual, so you should decide together with your doctor.

Even if the doctor assesses your psychomotor ability, you are at the same time responsible for assessing whether you are fit to drive a motor vehicle or perform work that requires sharpened attention. One of the factors that can affect your ability in these respects is the use of drugs due to their effects and/or side effects. Descriptions of these effects and side effects can be found in other sections. Read all the information in this leaflet for guidance. If you are not sure, talk to your doctor or pharmacist.
