Invexem 1 g Solution

INVEXEM contains ertapenem, which is an antibiotic of the beta-lactam group. Ertapenem can kill a wide range of bacteria (germs) that cause infections in various parts of the body. INVEXEM may be given to persons 3 months of age and older.

Your doctor may have prescribed INVEXEM to you or your child if you have one (or more) of the following types of infection:

• Infection in the abdomen
• Skin infections, including diabetic foot infections
• Infection in the lungs (pneumonia)
• Certain urinary infections
• Acute pelvic infections

INVEXEM should not be administered to you:

• if you are hypersensitive (allergic) to the active substance (ertapenem) or any of the other ingredients of INVEXEM (listed in section 6);
• if you are allergic to other beta-lactam antibiotics such as penicillins, cephalosporins (used to treat various infections);
• if you have bacterial meningitis (infection and inflammation of the membranes and fluid around the brain and spinal cord);
• if you are allergic to lidocaine (lignocaine) hydrochloride (a local anaesthetic). If INVEXEM is injected into the muscle, it is dissolved in a lidocaine (lignocaine) injection.

Warnings and precautions

Tell your doctor or healthcare provider before INVEXEM injection is given if you:

• have allergies to other medicines or other substances;
• get an allergic reaction (such as swelling of the face, tongue or throat, trouble breathing or swallowing, skin rash) during treatment (tell your doctor straight away as you may need urgent medical treatment). Serious, sometimes fatal allergic reactions have been reported with ertapenem (contained in INVEXEM). See section 4;
• have central nervous system disorders, such as localised tremors (shaking), or seizures (“fits”);
• are taking medicines called valproic acid or divalproex sodium (see “Other medicines and INVEXEM” below);
• have advanced kidney disease and if you get dialysis treatment;
• are going to have an operation that may take longer than 4 hours.

It is important that you tell your doctor if you have diarrhoea before, during or after your treatment with INVEXEM. This is because you may have a condition known as colitis (an inflammation of the bowel). Do not take any medicine to treat diarrhoea without first checking with your doctor.

Ertapenem may sometimes cause brain problems like confusion, seizures, or changes in consciousness (encephalopathy). If you notice these symptoms, your doctor might stop INVEXEM. People with kidney issues are more likely to experience these problems, and it might take longer for them to get better.

INVEXEM kills certain bacteria, but other bacteria and fungi may continue to grow more than normal and cause thrush or diarrhoea. This is called overgrowth. Your doctor will monitor you for overgrowth and treat you if necessary. See section 4 “Possible side effects”.

Children

Experience with INVEXEM is limited in children less than two years of age. In this age group your doctor will decide on the potential benefit of its use. There is no experience in children under 3 months of age. INVEXEM is therefore contraindicated in this age group (see “INVEXEM should not be administered”).

Do not share medicine prescribed for you with any other person. You will not be expected to give yourself INVEXEM. It will be given to you by a person who is qualified to do so.

Your healthcare provider will prepare INVEXEM and give it to you intravenously (into a vein) or intramuscularly (into a muscle). The recommended dose of INVEXEM for adults and adolescents 13 years of age and older is 1 gram (g) given once a day. The recommended dose for children 3 months to 12 years of age is 15 mg/kg given twice daily (not to exceed 1 g/day).

Your doctor will however prescribe a dose just suitable for you, or your child. The dose will depend on the type of infection you have and the condition of your kidneys. Your doctor will decide for how long to treat you, or your child. The duration will depend on the type of infection and your response on the treatment. It is very important that you continue to receive INVEXEM for as long as your doctor prescribes it.

If you are given more INVEXEM than you should Since a healthcare provider will administer INVEXEM, he/she will control the dosage. However, in the event of overdosage your doctor will manage the overdosage. If you are concerned that you may have been given too much INVEXEM, contact your doctor or another healthcare provider immediately.

If you miss a dose of INVEXEM Since a healthcare provider will administer INVEXEM, it is unlikely that the dose will be missed. If you are concerned that you may have missed a dose, contact your doctor or another healthcare provider immediately.

• Serious skin disorders, such as blistering or peeling of the skin, lesions on the skin and mucous membranes, an acute medicine rash (numerous small fluid-filled skin spots within large areas of red swollen skin).
• Severely upset stomach (pseudomembranous colitis). You may have inflammation of the bowels, that could be life-threatening. The symptoms may include severe abdominal pain and diarrhoea, or diarrhoea tinged with blood, vomiting and fever.
