Meropenem Eberth (Meropenem)

Meropenem is used to treat serious infections caused by susceptible bacteria, particularly in hospital settings.

• Complicated intra‑abdominal infection: provides broad coverage against mixed aerobic and anaerobic pathogens to resolve infection.
• Hospital‑acquired pneumonia/ventilator‑associated pneumonia: achieves bacterial eradication in the lungs.
• Complicated urinary tract infection: eliminates resistant Gram‑negative organisms in the urinary tract.
• Bacterial meningitis: penetrates the cerebrospinal fluid to treat central nervous system infections.
• Sepsis and febrile neutropenia: offers rapid bactericidal activity in systemic infections.

• Meropenem binds to penicillin‑binding proteins (PBPs) on the bacterial cell wall, inhibiting the final transpeptidation step of peptidoglycan synthesis. This disruption weakens the cell wall, leading to osmotic instability and bacterial cell death. Its high affinity for a broad range of PBPs underlies its activity against many Gram‑positive, Gram‑negative, and anaerobic organisms.

Adverse reactions to Meropenem may vary in frequency and severity.

Common Side Effects

• Nausea: mild to moderate upset stomach.
• Diarrhea: may be watery or loose.
• Headache: transient cranial discomfort.
• Rash: skin redness or itching.
• Elevated liver enzymes: mild hepatic enzyme rise.

Serious or Rare Side Effects

• Seizures: especially in patients with renal impairment or CNS disorders.
• Clostridioides difficile‑associated diarrhea: severe colitis risk.
• Anaphylaxis: acute allergic reaction requiring immediate care.
• Severe neutropenia: marked decrease in white blood cells.
• Renal impairment: worsening kidney function in susceptible individuals.

When using Meropenem, clinicians should consider several safety and monitoring factors.

• Renal function: adjust dose in patients with impaired clearance.
• Hypersensitivity: discontinue if allergic reaction occurs.
• Seizure risk: monitor patients with central nervous system disorders.
• Concomitant valproic acid: may reduce serum levels; consider alternative therapy.
• Antimicrobial stewardship: limit use to confirmed infections to prevent resistance.
• Store at 2-8°C: keep refrigerated, protect from light, do not freeze or shake.

Meropenem can affect or be affected by other medicines; awareness of key interactions helps prevent complications.

Major Interactions (Avoid)

• Valproic acid: reduced plasma concentrations; avoid co‑administration.
• Probenecid: increased meropenem levels; monitor renal function.
• High‑dose aminoglycosides: enhanced nephrotoxicity; monitor kidney function.

Moderate Interactions (Monitor Closely)

• NSAIDs: potential renal effects; monitor creatinine.
• Oral contraceptives: reduced efficacy reported; consider alternative contraception.
• Other antibiotics: possible antagonism; assess clinical need.
