1. What Yatrox is and what it is used for

Yatrox is a medicine that contains the active substance sodium fusidate. It belongs to a group of medicines called antibiotics, specifically fusidic acid derivatives, which work by stopping the growth of certain bacteria.

Yatrox is used for the treatment of infections caused by bacteria that are sensitive to fusidic acid. It is commonly prescribed for skin infections (such as infected eczema, impetigo), bone and joint infections, and certain types of respiratory tract infections when caused by susceptible bacteria. It may also be used in combination with other antibiotics to treat more serious infections, such as those associated with Staphylococcus aureus, including some resistant strains.

Yatrox is available in different forms, including tablets, oral suspension, and topical formulations (cream or ointment), depending on the type and location of the infection.

Yatrox belongs to the group of medicines known as antiemetics. Yatrox is used to:

• prevent nausea and vomiting caused by:
  • chemotherapy in the treatment of cancer in adults and children over 6 months of age.
  • radiotherapy in the treatment of cancer in adults.
• prevent postoperative nausea and vomiting in adults.

2. What you need to know before starting to take Yatrox

Do not take Yatrox:

• If you are allergic (hypersensitive) to ondansetron or to any of the components of Yatrox (listed in section 6).
• If you have had or have ever had an allergic reaction (hypersensitivity) to other medicines for nausea or vomiting (for example, granisetron or dolasetron).
• If you are taking apomorphine (a medicine used to treat Parkinson's disease).

If you think this applies to you, consult your doctor before taking Yatrox.

• rifampicin (an antibiotic used to treat infections such as tuberculosis).
