6. Contents of the pack and additional information

The active ingredient, hydrochloride of naltrexone, belongs to the group of medications “other

medications that act on the nervous system; medications used in addictive disorders”.

What is Tranalex used for

Tranalex is used in combination with other medications or treatments to help people dependent on opioid drugs overcome their addiction.

Tranalex acts by blocking receptors in the brain to neutralize the action of opioids. Patients will no longer experience the euphoria they previously felt after consuming opioids..

It is also indicated as a supporting treatment to maintain abstinence (self-denial) of patients dependent on alcohol.

Tranalex does not cause dependence.

Do not take Tranalex

• if you are allergic to naltrexone hydrochloride or any of the other ingredients in this

medication (listed in section 6).

• if you have severe kidney problems.

• if you have severe liver problems.

• if you have an acute liver infection.

• if you are dependent on opioids.

• if you are taking a medication that contains an opioid, for example, certain

medications for cough, medications to treat diarrhea (such as kaolin or morphine) and

analgesics (to relieve pain). Note: Tranalex does not block the effects of non-opioid analgesics (such as ibuprofen, paracetamol, and acetylsalicylic acid).

• If you are taking methadone.

If any of these situations apply to you, do not take the tablets. Consult your doctor first and follow their instructions.

Warnings and precautions

Consult your doctor or pharmacist before starting to take Tranalex.

• Do not take opioids while taking Tranalex. Although Tranalex will normally block some of the effects (i.e., the high), if you take high doses of opioids, you may experience respiratory difficulties and circulatory problems (opioid overdose).

• You must not use Tranalex if you are still addicted to opioids as Tranalex will cause severe withdrawal symptoms in this situation.

• You must inform all doctors who treat you that you are taking Tranalex. Non-opioid anesthetics should be used if you need an anesthetic in an emergency. If you need to use anesthetics that contain opioids, you may need higher doses than usual. You may also be more sensitive to side effects (respiratory difficulties and circulatory problems).

• Do not attempt to overcome the blocking effect of Tranalex with high doses of opioids. There is a risk that the opioids will still be present in your body after the effects of Tranalex have worn off. If this happens, you could experience an involuntary overdose with severe consequences.

• Naltrexone is eliminated from the body through the liver and kidneys. Liver problems are common in people dependent on opioids. Your doctor will perform liver function tests before and during treatment.

Inform your doctor if any of the above warnings apply to you, or if they did in the past.

Children and adolescents

Tranalex is not recommended for use in children and adolescents under 18 years of age, due to the absence of clinical data in this age group. Its safe use in children has not been established.

Use in elderly patients

There is insufficient data on the safety and efficacy of Tranalex for this

indication in elderly patients.

Other medications and Tranalex

Inform your doctor or pharmacist if you are taking, have taken recently, or may need to take any other medication.

Some common medications contain opioids and may not work when you are taking Tranalex. You must inform your doctor if you need medications for cough or medications against diarrhea or pain, as they may contain opioids.

If, despite the contraindication of concurrent use, in emergency situations you need medications that contain opioids, the appropriate dose to relieve pain may be higher than usual. It is absolutely necessary for the doctor to exercise close monitoring because the depression of respiration and other symptoms that occur may be more severe and prolonged.

Taking Tranalex with food and drinks

The intake of food or drinks does not affect your treatment with Tranalex.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor or pharmacist before using any medication.
