1. What TARGAXAN is and what it is used for

Targaxan contains the active substance rifaximin. Targaxan is an antibiotic that destroys bacteria, which can cause a disease called hepatic encephalopathy (symptoms include agitation, confusion, muscle problems, difficulty in speaking and in some cases coma).

Targaxan is used in adults with liver disease to reduce the recurrence of episodes of overt hepatic encephalopathy.

Targaxan can either be used alone or more commonly together with medicines containing lactulose (a laxative).

2. What you need to know before you take TARGAXAN

Do not take Targaxan:

  • if you are allergic to:
    • rifaximin
    • similar types of antibiotics (such as rifampicin or rifabutin)
    • any of the other ingredients of this medicine (listed in section 6).
  • if you have a blockage in your intestine

Warnings and precautions

Talk to your doctor or pharmacist before taking Targaxan.

While you are taking Targaxan your urine may turn a reddish colour. This is quite normal.

Treatment with any antibiotic including rifaximin may cause severe diarrhoea. This can happen several months after you have finished taking the medicine. If you have severe diarrhoea during or after using Targaxan you should stop taking Targaxan and contact your doctor immediately.

If your liver problems are severe your doctor will need to observe you carefully.

Targaxan contains sodium

This medicine contains less than 1 mmol sodium (23 mg) per tablet, that is to say essentially ‘sodium-free’.

Targaxan is not recommended for children and adolescents aged under 18 years. This medicine has not been studied in children and adolescents.

Pregnancy and breast-feeding

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking any medicine.

It is not known if Targaxan can harm your unborn baby. Targaxan is therefore not to be used if you are pregnant.

If you forget to take Targaxan
