Meropenem Sandoz is injected into your vein. It must always be given by a doctor or nurse.

Many people who get Meropenem Sandoz in hospital will have a drip (intravenous line). This medicine can be given directly into the vein or the drip without any need for an injection through the skin. It is given either as a slow injection over approximately 5 minutes or as a slow drip over 15 to 30 minutes.

Your doctor will decide which is best for you.

How much will you be given

Your doctor will decide what dose you will need depending on certain factors such as your type of infection and your age. The usual dose is 500mg to 1g injected every 8 hours. If you have meningitis you may require more, while a lower dose may be used for children or if you have kidney problems.

How long will you need to be given Meropenem Sandoz

This medicine needs to be given as a series of injections over a few days. Your doctor will decide how many days you will need to have Meropenem Sandoz for.

If you have been given too much (overdose)

As Meropenem Sandoz will be given to you under the supervision of your doctor, it is very unlikely that you will receive too much.

However, if you are concerned that you have been given too much, tell your doctor, nurse or pharmacist immediately or go to the Accident and Emergency at your nearest hospital.

You may need urgent medical attention.

Meropenem Sandoz has been associated with headache, tingling or prickling skin and convulsions/seizures (fits). Any of these could affect your ability to drive or operate machines.
