6. Further information
1. What Eptadone is and what it is used for
Eptadone contains a medicine called methadone. This belongs to a group of medicines which act on
your nervous system like morphine and diamorphine (also called heroin). They are sometimes called
‘opiates’. Eptadone is a liquid medicine which should only be taken by your mouth.
Eptadone is used:
• to treat addiction to medicines like morphine or heroin (opiates). It acts as a substitute for the addictive
drugs. Eptadone is addictive and may cause symptoms of dependence but it is less addictive than
medicines like heroin or morphine.
2. Before you take Eptadone
Do not take Eptadone if:
• you are allergic (hypersensitive) to methadone hydrochloride or any of the other ingredients of
Eptadone (listed in section 6)
• you are addicted to medicines which are not like morphine or heroin (‘opiate’ medicines)
• you have ever had breathing or lung problems such as asthma or COPD
• you are having an asthma attack
• you are going into labour or are in labour
• you are a child.
Do not take Eptadone if any of the above apply to you.
If you are not sure, talk to your doctor or pharmacist before taking Eptadone.
Take special care with Eptadone
Check with your doctor or pharmacist before taking your medicine if:
• you have kidney problems
• you have liver problems
• you have a severe headache or have recently had a head injury
• you have a raised pressure inside your skull
• you have heart problems, such as a problem with the way your heart beats
• you have been told by your doctor that you have an ‘electrolyte imbalance’ such as ‘hypokalaemia’
• you have low blood pressure
• you are in shock (you may have a very low blood pressure which can lead to collapse)
• you have an under-active thyroid gland
• you have a ‘hyper-active adrenal gland’
• you are a man who has prostate problems
• you are elderly (over 65 years of age).
• you are generally unwell.
If you are not sure if any of the above apply to you, talk to your doctor or pharmacist before taking
Taking other medicines
Please 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
Eptadone can affect the way some medicines work. Also some other medicines can affect the way
Eptadone works.
Do not take this medicine, and tell your doctor, if you are taking:
• medicines for depression called MAOIs (MonoAmine Oxidase Inhibitors) or have taken them in the
last 2 weeks. MAOIs are medicines such as moclobemide, phenelzine and tranylcypromine.
Tell your doctor if you are taking any of the following medicines:
• medicines for fungal infections such as fluconazole, itraconazole or ketoconazole
• medicines for epilepsy such as barbiturates, phenytoin or carbamazepine
• medicines for diarrhoea such as loperamide or co-phenotrope
• medicines that make your urine acid such as ammonium chloride
• medicines used to stop opiates working such as naltrexone
• medicines used to treat addiction such as buprenorphine
• medicines for depression such as fluoxetine, paroxetine, sertraline, nefazodone or fluvoxamine
• medicines for HIV such as nevirapine, delavirdine, didanosine stavudine, zidovudine, ritonavir, abacavir
or efavirenz
• antibiotics such as rifampicin, clarithromycin or erythromycin
• strong painkillers such as morphine, butorphanol, nalbuphine, pentazocine
• naloxone used to reverse the effects of opiate medicines
• octreotide used to treat some types of cancer and to reduce secretions
• verapamil used for heart problems
• ‘cannabinoids’ used for pain, such as dronabinol and nabilone.
If you are not sure if any of the above apply to you, talk to your doctor or pharmacist before taking
Taking Eptadone with food and drink
Do not drink alcohol while taking this medicine. This is because alcohol may increase the side effects
of methadone such as breathing problems and feeling dizzy because of low blood pressure. Do not
drink grapefruit juice while you are taking this medicine. This is because grapefruit juice can change
the effect of methadone.
Pregnancy and breast-feeding
• Do not take Eptadone if you are going into labour or are in labour.
• Talk to your doctor before taking Eptadone if you are pregnant or likely to become pregnant.
• Talk to your doctor before taking Eptadone if you are breast-feeding. This is because small amounts
may pass into the mother’s milk.

Driving and using machines:
Eptadone may make you feel drowsy and less alert and will affect your ability to drive or use any tools
or machines.

• This will happen while you are taking it, and also for some time afterwards.
• Only start driving or using tools or machines when your doctor says it is OK.
