1. What OXCIVA is and what it is used for

OXCIVA contains the active substance oxacillin, which belongs to a class of medicines called beta-lactams, beta-lactamase-resistant penicillins.
Oxacillin acts against susceptible bacteria causing skin, bone, and respiratory tract infections.
OXCIVA is also indicated for severe infections such as endocarditis (inflammation of the inner lining of the heart), meningitis (inflammation of the meninges), and septicemia (blood infection). It may also be used to prevent postoperative infections.
Oxacillin may also be used for other types of infections, as directed by the treating physician.
This medicine is used in adults and children from birth onwards to treat the following infections:

  • endocarditis,
  • meningitis,
  • pneumonia,
  • joint infections,
  • osteomyelitis,
  • skin and soft tissue infections,
  • prophylaxis of postoperative infections (including neurosurgery, plastic surgery, etc.),
  • bacteraemia associated with or suspected to be associated with the infections listed above,
  • prophylaxis of postoperative infections in:
    • neurosurgery: craniotomy and placement of an internal cerebrospinal fluid shunt
    • plastic and reconstructive surgery of varying complexity

Current guidelines for antibiotic use should be taken into consideration.

2. What you need to know before using OXCIVA

Do not use OXCIVA:

  • If you are allergic to oxacillin, to other beta-lactam antibiotics (penicillins and cephalosporins), or to any of the other ingredients of this medicine (listed in section 6). If allergic reactions occur, stop treatment immediately and inform your doctor.

Warnings and precautions
Talk to your doctor or pharmacist before using OXCIVA.
Any allergic reaction occurring during treatment must be reported to your doctor immediately.
Before starting this treatment, inform your doctor if you have previously experienced an allergic reaction during antibiotic therapy (even with another class of antibiotics), including: urticaria or other skin rashes, itching, sudden allergic-type swelling of the face and throat (angioedema) (see section 4).
Diarrhoea may occur during treatment with antibiotics, including OXCIVA, and may even appear several weeks after treatment has ended. If severe or persistent diarrhoea occurs, or if you notice blood or mucus in your stools, stop taking OXCIVA immediately. Do not take medicines that block or slow intestinal transit and contact your doctor (see section 4).

Other medicines and OXCIVA
Inform your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines, including methotrexate (a medicine used to treat cancer or rheumatoid arthritis), probenecid (a medicine used to treat gout), or another antibiotic, including over-the-counter medicines.

Pregnancy and breastfeeding
If you are pregnant, think you may be pregnant, planning to become pregnant, or are breastfeeding, consult your doctor or pharmacist before using this medicine.

Pregnancy
OXCIVA should not be taken during pregnancy unless specifically recommended by your doctor.

Breastfeeding
Small amounts of penicillins pass into breast milk, and the quantities ingested by the infant are much lower than neonatal therapeutic doses. Nevertheless, caution should be exercised when oxacillin is administered to breastfeeding mothers. If the infant develops adverse effects such as diarrhoea, skin rash, or candidiasis (an infection caused by certain microscopic fungi), inform your doctor immediately, as these effects in the infant may be related to the use of this medicine.
Consult your doctor or pharmacist before taking any medicine.

Driving and using machines
OXCIVA does not affect the ability to drive or operate machinery.

OXCIVA contains sodium
This medicine contains approximately 64 mg of sodium (the main component of table/cooking salt) per vial. This corresponds to 3.2% of the maximum recommended daily dietary intake of sodium for an adult.
