6.Contents of the pack and additional information

Eptadone contains a medicine called methadone, which belongs to a group of medicines that act on the nervous system like morphine and diamorphine (also known as heroin). Sometimes they are known as “opioids”. Eptadone is a liquid drinkable medicine that should only be taken orally.

Eptadone is used:

• to treat addiction to drugs such as morphine or heroin (opioids). It acts as a substitute for the addictive substances, but is less addictive

Do not take Eptadone:

• If you are allergic to hydrochloride of metadone or any of the other components of this medication (listed in section 6).
• If you have addiction to medications that are not like morphine or heroin (opioid medications).
• If you have had respiratory or pulmonary problems, now or in the past.
• If you are expecting to give birth.

Warnings and precautions

Consult your doctor or pharmacist before starting to take Eptadone:

• If you have kidney problems.
• If you have liver problems.
• If you have a severe headache or have had a head injury recently.
• If you have been diagnosed with high intracranial pressure.
• If you have heart problems, such as rhythm problems.
• If you have low blood pressure.
• If you have been diagnosed with low thyroid function.
• If you have been diagnosed with high adrenal function.
• If you are a man with prostate problems.
• If you are over 65 years old.
• If you usually feel unwell.

Speak with your doctor or pharmacist if you experience any of the following symptoms while taking Eptadone:

• Weakness, fatigue, loss of appetite, nausea, vomiting, or low blood pressure. This may be a sign that your adrenal glands are producing very low levels of cortisol, so you may need to take a hormone supplement.

Long-term use may cause a decrease in sex hormone levels and an increase in prolactin levels. Consult your doctor if you experience symptoms such as decreased libido, impotence, or absence of menstruation (amenorrhea).

Tolerance, dependence, and addiction

This medication contains an opioid medication called metadone. Repeated use of opioids can reduce the effectiveness of the medication (your body gets used to the medication, this is known as tolerance). Repeated use of Eptadone can also cause dependence, abuse, and addiction, which can lead to a potentially fatal overdose.

Dependence or addiction can make you feel like you no longer have control over the amount of medication you need to take or how often you need to take it.

The risk of becoming dependent or addicted varies from person to person. You may be at a higher risk of becoming dependent or addicted to Eptadone if:

• You or a family member have a history of alcohol, prescription medication, or illicit substance abuse (addiction).
• You are a smoker.
• You have had problems with your mood (depression, anxiety, or personality disorder) or have received treatment from a psychiatrist for other mental health conditions.

If you notice any of the following signs while taking Eptadone, it could be a sign that you have become dependent or addicted:

• You need to take the medication for a longer period than recommended by your doctor.
• You need to take more doses than recommended.
• You are using the medication for reasons other than those prescribed, such as "to calm down" or "to help you sleep".
• You have made repeated and unsuccessful attempts to stop or control the use of the medication.
• You do not feel well when you stop taking the medication and feel better when you take it again (abstinence symptoms).

If you notice any of these signs, speak with your doctor to address the most suitable therapeutic strategy for your case, including when it is appropriate to stop taking it and how to do it safely (see section 3 "If you interrupt treatment with Eptadone").

Respiratory problems related to sleep

Eptadone can cause respiratory problems related to sleep, such as sleep apnea (pauses in breathing during sleep) and sleep-related hypoxemia (low oxygen levels in the blood). Symptoms may include pauses in breathing during sleep, nocturnal awakenings due to lack of breath, difficulty maintaining sleep, or excessive daytime somnolence. If you or someone else observes these symptoms, contact your doctor. Your doctor may consider reducing the dose.

Children and adolescents

This medication is contraindicated in children.

Use in athletes:

This medication contains Metadone, which can produce a positive result in doping tests.

Other medications and Eptadone

Inform your doctor or pharmacist if you are using or have used recently or may need to use any other medication. Eptadone may affect how some medications work. Additionally, other medications may affect how Eptadone works.

Do not take this medication and consult your doctor if you are taking:

• Depression medications called IMAO (monoamine oxidase inhibitors) or have taken them in the last 2 weeks. IMAO medications are medications such as moclobemide, phenelzine, and tranylcypromine.

Consult your doctor if you are taking any of the following medications:

• Fungal infection medications such as fluconazole, itraconazole, or ketoconazole.
• Epilepsy medications such as barbiturates, phenytoin, or carbamazepine.
• Diarhea medications such as loperamide or co-phenotrope.
• Medications that acidify the urine such as ammonium chloride.
• Medications used to stop the action of opioids such as naltrexone.
• Medications used to treat addiction such as buprenorphine.
• Depression medications such as fluoxetine, paroxetine, sertraline, nefazodone, or fluvoxamine.
• Medications for HIV such as nevirapine, delavirdine, didanosine, stavudine, zidovudine, ritonavir, abacavir, or efavirenz.
• Antibiotics such as rifampicin, clarithromycin, or erythromycin.
• Potent analgesics such as morphine, butorphanol, nalbuphine, pentazocine.
• Naloxone used to neutralize the effects of opioid medications.
• Octreotide used to treat certain types of cancer and to reduce secretions.
• Verapamil used to treat heart problems.
• "Cannabinoids" used for pain, such as dronabinol and nabilone.
• Metamizol, a medication used to treat pain and fever.
• Cannabidiol (a medication used to treat seizures).
• Gabapentin and pregabalin (medications used to treat epilepsy, nerve pain, or anxiety). These may increase the risk of opioid overdose, respiratory depression (difficulty breathing), and may be potentially fatal.
• Calming medications called benzodiazepines, such as diazepam or flunitrazepam.
  The concomitant use ofEptadoneand sedative medications such as benzodiazepines or related medications increases the risk of somnolence, difficulty breathing (respiratory depression), coma, and may be potentially fatal.Therefore, it should only be considered when other treatment options are not possible.
  However, if your doctor prescribesEptadonealong with sedative medications, your doctor should limit the dose and duration of concomitant treatment.
  Inform your doctor about all sedative medications you are taking and follow your doctor's recommendations regarding the dose. It may be helpful to inform friends or family members who are aware of the signs and symptoms mentioned above. Contact your doctor when you experience these symptoms.

The risk of side effects increases if metadone is consumed simultaneously with antidepressants (such as citalopram, duloxetine, escitalopram, fluoxetine, fluvoxamine, paroxetine, sertraline, venlafaxine, amitriptyline, clomipramine, imipramine, nortriptyline). Consult your doctor if you experience symptoms such as:

• Changes in mental state (such as restlessness, hallucinations, coma)
• Fast pulse, unstable blood pressure, fever
• Increased reflexes, discoordination, muscle rigidity
• Gastrointestinal symptoms (such as nausea, vomiting, diarrhea)

If you are unsure if any of the above points apply to you, consult your doctor or pharmacist before taking Eptadone.
