Meronem 500mg Injection

Meronem 500mg Injection contains Meropenem, a carbapenem antibiotic used to treat a wide range of serious bacterial infections in adults and children.

Benefits

Meropenem 500mg is a broad-spectrum antibiotic effective against various severe bacterial infections, including those caused by multi-drug resistant organisms. It works by killing the bacteria or preventing their growth, helping to eliminate concurrent bacteraemia.

Uses and Indications

• Pneumonia, including community-acquired, nosocomial, hospital-associated, and ventilator-associated pneumonia.
• Broncho-pulmonary infections in cystic fibrosis.
• Complicated urinary tract infections.
• Complicated intra-abdominal infections.
• Intra- and post-partum infections (gynaecological infections such as endometritis).
• Complicated skin and soft tissue infections.
• Acute bacterial meningitis.
• Management of febrile neutropenic patients where bacterial infection is suspected.
• Treatment of bacteraemia associated with any of the listed infections.

The Meronem 500mg Injection contains:

• Meropenem trihydrate equivalent to 500 mg anhydrous Meropenem (active ingredient).
• Anhydrous sodium carbonate (excipient).
• Approximately 45 mg of sodium per 500 mg vial.

Dosage and Administration

1. Meronem 500mg Injection is administered intravenously, either as an infusion over approximately 15 to 30 minutes or as a bolus injection over approximately 3 to 5 minutes.
2. The dose and duration of treatment depend on the type and severity of the infection, the patient's condition, and renal function.
3. For adults, a typical dose is 500 mg every 8 hours for certain infections like pneumonia, urinary tract infections, gynaecological infections, and skin and soft tissue infections.
4. For bolus administration, Meronem 500mg should be reconstituted with sterile water for injection to a final concentration of 50 mg/mL.
5. For intravenous infusion, it can be reconstituted directly with 0.9% sodium chloride solution or 5% dextrose solution, or reconstituted with sterile water for injection and then diluted with a compatible infusion fluid.
6. The injection should be given at evenly spaced times each day.

Storage and Disposal

• Store the dry powder vials at controlled room temperature, typically not above 30°C. Do not freeze.
• After reconstitution, solutions for intravenous bolus injection (50 mg/mL in water for injection) are stable for 3 hours at up to 25°C or 12-16 hours under refrigerated conditions (2-8°C).
• Solutions for intravenous infusion reconstituted with 0.9% sodium chloride are stable for 3-6 hours at up to 25°C or 15-24 hours under refrigerated conditions (2-8°C).
• Solutions reconstituted with 5% dextrose should be used immediately.
• Any unused product or waste material should be disposed of in accordance with local requirements.
• Keep out of the sight and reach of children.

Precautions and Safety

• Meronem 500mg Injection is contraindicated in patients with known hypersensitivity to meropenem, other carbapenem antibiotics, penicillins, or other beta-lactam antibiotics.
• Careful inquiry about previous hypersensitivity reactions to beta-lactam antibiotics should be made before starting therapy.
• Patients with a history of central nervous system disorders (e.g., brain lesions, seizures) or renal impairment should use this medicine with caution, as seizures have been reported.
• Hepatic function should be closely monitored during treatment due to the risk of drug-induced liver injury.
• Severe diarrhea, including Clostridium difficile-associated diarrhea, has been reported and should be considered in patients presenting with diarrhea during or after treatment.
• Concomitant use with valproic acid/sodium valproate/valpromide is not recommended as meropenem may decrease its effect.
• This medicine may cause serious skin reactions; if signs appear, treatment should be withdrawn immediately.
• Meropenem may affect coordination, reaction time, or judgment; patients should not drive or operate machinery until they know how it affects them.
• Pregnancy and breastfeeding: It is preferable to avoid meropenem during pregnancy. Small amounts may pass into breast milk, so the doctor will decide on its use during breastfeeding.

Side Effects and Risks

• Common side effects include headache, nausea, vomiting, diarrhea, constipation, abdominal pain, and pain, redness, or swelling at the injection site.
• Other possible side effects include skin rash, itchy skin, increased numbers of platelets, changes in liver and kidney function blood tests, tingling sensation, mouth or vaginal thrush, inflammation of the bowel with diarrhea, and sore veins at the injection site.
• Serious side effects, though less common, can include severe allergic reactions (hives, itching, swelling of face/throat/tongue, difficulty breathing), seizures, severe watery or bloody diarrhea, severe skin reactions (blistering, peeling skin, red lesions), unusual tiredness or weakness, pale skin, fast or irregular heartbeat, shortness of breath, return of fever, muscle pain/tenderness/weakness (rhabdomyolysis), and liver problems (yellowing of skin/eyes, dark urine).
• Consult a doctor if side effects bother you or do not go away, or if any serious side effects occur.
