1. What Meropenem is and what it is used for

Meropenem belongs to a group of medicines called carbapenem antibiotics. It works by killing bacteria, which can cause serious infections.

Meropenem is used to treat the following in adults and children aged 3 months and older:

  • Infection affecting the lungs (pneumonia).
  • Lung and bronchial infections in patients suffering from cystic fibrosis.
  • Complicated urinary tract infections.
  • Complicated infections in the abdomen.
  • Infections that you can catch during or after the delivery.
  • Complicated skin and soft tissues infections.
  • Acute bacterial infection of the brain (meningitis).

Meropenem may be used in the management of neutropenic patients with fever that is suspected to be due to a bacterial infection.

Meropenem may be used to treat bacterial infection of the blood which might be associated with a type of infection mentioned above.

2. What you need to know before you use Meropenem
Do not use Meropenem
  • If you are allergic (hypersensitive) to meropenem or any of the other ingredients of this medicine (listed in Section 6).
  • If you are allergic (hypersensitive) to other antibiotics such as penicillins, cephalosporins or carbapenems as you may also be allergic to meropenem.

Warnings and precautions

Talk to your doctor, pharmacist or nurse before using Meropenem.

  • If you have health problems, such as liver or kidney problems.
  • If you have had severe diarrhoea after taking other antibiotics.

You may develop a positive test (Coombs test) which indicates the presence of antibodies that may destroy red blood cells. Your doctor will discuss this with you.

You may develop signs and symptoms of severe skin reactions (see section 4). If this happens talk to your doctor or nurse immediately so that they can treat the symptoms.

Liver problems

If you notice yellowing of the skin and eyes, itchy skin, dark-coloured urine or light-coloured stool tell your doctor. This may be a sign of liver problems which your doctor needs to check.

If you are not sure if any of the above applies to you, talk to your doctor or nurse before using Meropenem.

Other medicines and Meropenem

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

This is because Meropenem can affect the way some medicines work and some medicines can have an effect on Meropenem.

In particular, tell your doctor or nurse if you are taking any of the following medicines:

  • Probenecid (used to treat gout).
  • Valproic acid/sodium valproate/valpromide (used to treat epilepsy). Meropenem should not be used because it may decrease the effect of sodium valproate.
  • Oral anti-coagulant agent (used to treat or prevent blood clots).

Pregnancy, breast-feeding and fertility

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 using this medicine. It is preferable to avoid the use of meropenem during pregnancy. Your doctor will decide whether you should use meropenem.

It is important that you tell your doctor if you are breast-feeding or if you intend to breast-feed before receiving meropenem. Small amounts of this medicine may pass into the breast milk. Therefore, your doctor will decide whether you should use meropenem while breast-feeding.

Driving and using machines

No studies on the effect on the ability to drive and use machines have been performed. Meropenem has been associated with headache; tingling or pricking skin (paraesthesia). Any of these side effects could affect your ability to drive or operate machines.

Meropenem may cause and involuntary muscle movements, leading the person's body to shake rapidly and uncontrollably (convulsions). This is usually accompanied with a loss of consciousness. Do not drive or use machines if you experience this side effect.

The maximum recommended daily dose of this medicinal product contains 540 mg sodium (found in table salt). This is equivalent to 27% of the adult recommended maximum daily dietary intake for sodium.

Meropenem 500 mg

Talk to your doctor if you need 9 or more vials daily for a prolonged period, especially if you have been advised to follow a low salt (sodium) diet.

Meropenem 1 g

Talk to your doctor if you need 5 or more vials daily for a prolonged period, especially if you have been advised to follow a low salt (sodium) diet.

3. How to use Meropenem

Always use this medicine exactly as your doctor or nurse has told you. Check with your doctor or nurse if you are not sure.

Use in Adults
  • The dose depends on the type of infection that you have, where the infection is in the body and how serious the infection is. Your doctor will decide on the dose that you need.
  • The dose for adults is usually between 500 mg (milligrams) and 2 g (gram). You will usually receive a dose every 8 hours. However you may receive a dose less often if your kidneys do not work very well.

Use in children and adolescents
  • The dose for children over 3 months old and up to 12 years of age is decided using the age and weight of the child. The usual dose is between 10 mg and 40 mg of Meropenem for each kilogram (kg) that the child weighs. A dose is usually given every 8 hours.
    Children who weigh over 50 kg will be given an adult dose.

How to use Meropenem
  • Meropenem will be given to you as an injection or infusion into a large vein.
  • Your doctor or nurse will normally give Meropenem to you.
  • However, some patients, parents and carers are trained to give Meropenem at home.

Always use Meropenem exactly as your doctor has told you. You should check with your doctor if you are not sure.
  • Your injection should not be mixed with or added to solutions that contain other medicines.
  • The injection may take about 5 minutes or between 15 and 30 minutes. Your doctor will tell you how to give Meropenem.
