* CrCl 10-29 mL/min: 1 gram IV every 12 hours.
* CrCl <10 mL/min: 1 gram IV every 24 hours.
* Hemodialysis: 1 gram IV every 24 hours, administer after dialysis.
* **Hepatic Impairment:** No dose adjustment required.
## Contraindications
* Hypersensitivity to Mega%2525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252520cv or other beta-lactam antibiotics.
## Adverse Effects
Common adverse effects include diarrhea, nausea, vomiting, rash, and injection site reactions. Serious adverse effects include Clostridioides difficile-associated diarrhea, hypersensitivity reactions, and seizures (rarely, especially with renal impairment).
## Key Drug Interactions
* **Probenecid:** May increase serum concentrations of Mega%2525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252520cv.
* **Aminoglycosides:** Concurrent administration may lead to additive nephrotoxicity or ototoxicity.
* **Warfarin:** May alter INR; monitor INR closely.
## Monitoring
* Renal function (BUN, creatinine) is crucial for dose adjustments.
* Monitor for signs and symptoms of hypersensitivity reactions.
* Assess for diarrhea and consider testing for C. difficile if suspected.
* Monitor therapeutic drug levels if clinically indicated, particularly in critically ill patients or those with altered pharmacokinetics.
## Clinical Pearls
* Administer as an intravenous infusion over 30 minutes.
* Reconstituted solution should be used within 1 hour if stored at room temperature or within 24 hours if refrigerated.
* Ensure adequate hydration to minimize the risk of crystalluria.
* Spectrum of activity includes many Gram-positive and Gram-negative organisms, including some resistant strains.
