• I.M. injection in patients allergic to lidocaine or other amide local anesthetics
Use cautiously in:
• seizure disorder

☞ Monitor vital signs, ECG, and cardiovascular status closely. Stay alert for arrhythmias, edema, respiratory distress, and other signs and symptoms of heart failure.
☞ Assess neurologic status, and watch for signs of impending seizure.
☞ Monitor bowel pattern, and stay alert for signs and symptoms of pseudomembranous colitis.
• Inspect injection site for evidence of thrombophlebitis and induration.
☞ Watch for indications of erythema multiforme (sore throat, rash, cough, iris lesions, mouth sores, fever). Report early signs before condition progresses to Stevens-Johnson syndrome, and stay alert for other hypersensitivity reactions (including anaphylaxis).
• Tell patient to notify nurse right away if drug causes pain or swelling at injection site.
• Inform patient that drug can be toxic to many organ systems. Tell him to promptly report significant adverse reactions.
• Tell female patient to inform prescriber of pregnancy or breastfeeding before taking drug.
• As appropriate, review all other significant and life-threatening adverse reactions and interactions, especially those related to the drugs mentioned above.

Adverse Reactions/Side Effects
Central nervous system
- seizures (life-threatening)
- pseudomembranous colitis (life-threatening)
- phlebitis at IV site
- pain at IM site
- hypersensitivity reaction including anaphylaxis (life-threatening)
Drug-Drug interactionProbenecid ↓ excretion and ↑ blood levels.May ↓ serum valproate levels (↑ risk of seizures).
Renal ImpairmentIntramuscular Intravenous (Adults) CCr ≤30 mL/min/1.73m2—500 mg once daily.
- Assess for infection (vital signs; appearance of wound, sputum, urine, and stool; WBC) at beginning of and during therapy.
- Obtain a history before initiating therapy to determine previous use of and reactions to penicillins, cephalosporins, or carbapenems. Persons with a negative history of penicillin sensitivity may still have an allergic response.
- Obtain specimens for culture and sensitivity before initiating therapy. First dose may be given before receiving results.
- Observe patient for signs and symptoms of anaphylaxis (rash, pruritus, laryngeal edema, wheezing). Discontinue the drug and notify the physician immediately if these occur. Have epinephrine, an antihistamine, and resuscitative equipment close by in the event of an anaphylactic reaction.
- Monitor bowel function. Diarrhea, abdominal cramping, fever, and bloody stools should be reported to health care professional promptly as a sign of pseudomembranous colitis. May begin up to several weeks following cessation of therapy.
- Lab Test Considerations: May cause ↑ AST, ALT, serum alkaline phosphatase levels.
- May cause ↑ platelet and eosinophil counts.
