TRANALEX 50 mg Film-Coated Tablets

2. What you need to know before you take Tranalex

Do not take Tranalex

• if you are allergic to naltrexone hydrochloride or any of the other ingredients of this medicine (listed in section 6).

if you have severe kidney problems.

• if you have severe liver problems.
• if you have an acute infection in the liver.
• if you are dependent on opiates.
• if you are taking a medicine that contains an opiate, for example, certain cough medicines, anti-diarrheal medicines (such as kaolin or morphine) and painkillers (to relieve pain). Note: Tranalex does not block the effects of painkillers that do not contain opiates (such as ibuprofen, paracetamol, and acetylsalicylic acid).

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 opiates while taking Tranalex. Although Tranalex will normally block some of the effects (i.e., the elevated effects), if you take high doses of opiates, you may experience breathing difficulties and circulatory problems (opiate intoxication).
• You must not use Tranalex if you are still addicted to opiates, as Tranalex will cause severe withdrawal symptoms in this situation.
• You should inform all doctors who treat you that you are taking Tranalex. Non-opiate anesthetics should be used if you need an anesthetic in an emergency situation. If you have to use anesthetics that contain opiates, you may need higher doses than usual. You may also be more sensitive to side effects (breathing difficulties and circulatory problems).
• You should not try to overcome the blocking effect of Tranalex with high doses of opiates. There is a risk that the opiates will still be in your body after the effects of Tranalex have passed. If this happens, you could suffer an unintentional overdose with serious consequences.
• Naltrexone is eliminated from the body through the liver and kidneys. Liver problems are common in people dependent on opiates. Your doctor will perform liver function tests before and during treatment.

Tell your doctor if any of the above warnings are applicable to you, or if they were in the past.

Children and adolescents

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

Use in elderly patients

There is not enough data on the safety and efficacy of Tranalex for this indication in elderly patients.

Other medicines and Tranalex

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.

Some common medicines contain opiates and may not work when you are taking Tranalex. You should tell your doctor if you need medicines for coughs or medicines for diarrhea or pain, as they may contain opiates.

If, despite the contraindication of combined use, in cases of emergency, medicines that contain opioids are needed, the dose suitable for pain relief may be higher than usual. It is absolutely necessary to have close medical supervision because the respiratory depression and other symptoms that occur may be stronger and more lasting.

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 medicine.

The safety of using Tranalex during pregnancy has not been demonstrated.

It is not known if Tranalex is excreted in breast milk. Since the safety of Tranalex in neonates and children has not been demonstrated, breastfeeding is not recommended while taking Tranalex.

Naltrexone may decrease the physical and/or mental abilities necessary for performing potentially hazardous activities such as driving a car or operating machinery.

Tranalex contains lactose
