5 Conservation of Meropenem
Meropenem belongs to a group of medicines called carbapenem antibiotics.
Antibiotics are used to treat bacterial infections and do not work for viral infections such as the flu or the common cold.
It is important that you follow the instructions regarding the dose, administration interval, and treatment duration indicated by your doctor.
Do not store or reuse this medicine. If you have any leftover antibiotic after finishing the treatment, return it to the pharmacy for proper disposal. Do not throw away medicines via wastewater or household waste.
It works by killing bacteria that can cause serious infections.
Meropenem is used to treat the following infections in adults and children from 3 months of age:
??Infection affecting the lungs (pneumonia)
??Bronchial and lung infections in patients with cystic fibrosis
??Complicated urinary tract infections
??Complicated infections in the abdomen
??Infections that you can acquire during and after childbirth
??Complicated skin and soft tissue infections
??Acute bacterial infection of the brain (meningitis)
Meropenem may be used to treat patients with neutropenia who have fever that is suspected to be due to a bacterial infection.
Meropenem can be used to treat bacterial infection of the blood that may be associated with one of the aforementioned infections.
Do not use Meropenem if
?? you are allergic (hypersensitive) to meropenem or any of the other ingredients of this medicine (listed in section 6).
?? you are allergic (hypersensitive) to other antibiotics such as penicillins, cephalosporins, or carbapenems, as you may also be allergic to meropenem.
Warnings and precautions
Consult your doctor, pharmacist, or nurse before starting to use Meropenem if:
?? you have health problems, such as liver or kidney problems.
?? you have had severe diarrhea after taking other antibiotics.
You may develop a positive reaction to a test (Coombs test) that indicates the presence of antibodies that can 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, inform your doctor or nurse immediately so that they can treat the symptoms.
If you notice muscle pain, sensitivity, or unexplained weakness, and/or dark urine, inform your doctor immediately. This could be a sign of muscle deterioration (rhabdomyolysis), which can cause kidney problems.
Liver problems
Tell your doctor if you notice yellowing of the skin and eyes, itching of the skin, dark-colored urine, or light-colored stools. This may be a sign of liver problems that your doctor should check.
If you are in any of these situations, or if you have doubts, consult your doctor or nurse before using Meropenem.
Other medicines and MeropenemInform your doctor, pharmacist, or nurse if you are using, have recently used, or might use any other medicines, including those obtained without a prescription and herbal medicines.
This is because Meropenem can affect the way some medicines work, and some of these may have an effect on Meropenem.
In particular, inform your doctor, pharmacist, 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, as it can decrease the effect of sodium valproate.
?? Oral anticoagulant agent (used to treat or prevent blood clots).
Pregnancy and breastfeeding
If you are pregnant or breastfeeding, 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 if you should use meropenem.
It is important that you inform your doctor if you are breastfeeding or plan to breastfeed before receiving meropenem. Small amounts of this medicine pass into breast milk. Therefore, your doctor will decide if you should use meropenem during breastfeeding.
Driving and using machines
No studies on the effects on the ability to drive and use machines have been performed.
However, Meropenem has been associated with headache, tingling, or numbness of the skin (paresthesia). Any of these side effects may affect your ability to drive or use machines.
Meropenem may cause involuntary muscle movements, leading to rapid and uncontrolled body agitation (convulsions), which is usually accompanied by loss of consciousness. Do not drive or use machines if you experience this side effect.
Meropenem contains sodium.
Meropenem 500 mg: This medicine contains 45 mg of sodium (main component of table/cooking salt) per 500 mg. This is equivalent to 2.25% of the maximum recommended daily sodium intake for an adult.
If you have a condition that requires you to control your sodium intake, inform your doctor, pharmacist, or nurse.
Follow exactly the administration instructions of this medicine indicated by your doctor or pharmacist. If in doubt, consult your doctor or pharmacist again.
Use in adults
??The dose depends on the type of infection you have, the area of the body where it is located, and its severity. Your doctor will decide what dose you need.
??The normal dose in adults is between 500 mg (milligrams) and 2 g (grams). You will usually be given a dose every 8 hours. However, if your kidneys do not work well, you may receive the dose less frequently.
Use in children and adolescents
The dose for children over 3 months and up to 11 years is decided using the child's age and weight. The normal dose is between 10 mg and 40 mg of meropenem per kilogram (kg) of the child's weight. You will usually be given a dose every 8 hours. Children who weigh over 50 kg will be given an adult dose.
How to use Meropenem
??Meropenem will be administered to you as an injection or infusion into a large vein.
??Meropenem will usually be administered by your doctor or nurse.
??However, some patients, parents, or caregivers are trained to administer meropenem at home.

Follow exactly the administration instructions of Meropenem indicated by your doctor. Consult your doctor if you have doubts.

Health Advice/Education
Antibiotics are used to treat infections caused by bacteria. They have no effect against infections caused by viruses.
Sometimes a bacterial infection does not respond to treatment with an antibiotic. One of the most common reasons for this to happen is that the bacteria causing the infection are resistant to the antibiotic being taken. This means they can survive and even multiply, despite the antibiotic.
Bacteria can become resistant to antibiotics for many reasons. Using antibiotics with caution can help reduce the opportunity for bacteria to become resistant to them.
When your doctor prescribes you antibiotic treatment, it is to treat only your current illness. Paying attention to the following tips will help prevent the appearance of resistant bacteria that could stop the activity of the antibiotic.
