From the Guidelines
For an 88-year-old patient experiencing seizure-like movements while recovering from agranulocytosis and retropharyngeal abscess on daptomycin, this medication should be discontinued immediately and the patient's healthcare provider notified. Daptomycin can cause neuromuscular symptoms including muscle twitching, tremors, and rarely seizures, particularly in elderly patients or those with renal impairment 1. Alternative antibiotics such as linezolid or clindamycin (depending on culture results) should be considered. The patient needs urgent neurological evaluation, including an EEG to rule out true seizures, and laboratory tests to check electrolytes, renal function, and drug levels. Supportive care should include seizure precautions, maintaining a safe environment, and close monitoring of vital signs. These symptoms often resolve within 48-72 hours after stopping daptomycin. Renal dosing of any replacement antibiotics is crucial given the patient's advanced age and potential for decreased kidney function, which may have contributed to daptomycin toxicity.
Key Considerations
- Daptomycin has been associated with neuromuscular symptoms, including muscle twitching, tremors, and seizures, particularly in elderly patients or those with renal impairment 1.
- Alternative antibiotics such as linezolid or clindamycin may be considered, depending on culture results.
- Urgent neurological evaluation, including an EEG, is necessary to rule out true seizures.
- Laboratory tests should be conducted to check electrolytes, renal function, and drug levels.
- Supportive care, including seizure precautions and close monitoring of vital signs, is essential.
Treatment Options
- Linezolid has been shown to be effective in treating complicated skin and soft tissue infections, including those caused by MRSA 1.
- Clindamycin may also be considered as an alternative antibiotic, depending on culture results.
- Renal dosing of any replacement antibiotics is crucial to avoid toxicity, particularly in elderly patients with potential kidney function decline.
Monitoring and Follow-up
- Close monitoring of the patient's vital signs and neurological status is necessary after discontinuing daptomycin.
- Follow-up laboratory tests should be conducted to ensure that the patient's electrolytes, renal function, and drug levels return to normal.
- The patient's response to alternative antibiotics should be closely monitored, and adjustments made as necessary to ensure effective treatment.

5 WARNINGS AND PRECAUTIONS
5.1 Anaphylaxis/Hypersensitivity Reactions Anaphylaxis/hypersensitivity reactions have been reported with the use of antibacterial agents, including daptomycin for injection, and may be life-threatening. 5.2 Myopathy and Rhabdomyolysis Myopathy, defined as muscle aching or muscle weakness in conjunction with increases in creatine phosphokinase (CPK) values to greater than 10 times the upper limit of normal (ULN), has been reported with the use of daptomycin for injection.
The patient's sister-like movement while recovering from agranulocytosis and retropharyngeal abscess on daptomycin may be related to myopathy or peripheral neuropathy, which are potential side effects of daptomycin.
- Key considerations:
- Monitor the patient for signs and symptoms of myopathy or peripheral neuropathy.
- Consider discontinuing daptomycin if the patient develops unexplained signs and symptoms of myopathy or peripheral neuropathy.
- CPK levels should be monitored weekly, and more frequently in patients with renal impairment 2.
From the Research
Movement and Recovery
- For an 88-year-old patient recovering from agranulocytosis and retropharyngeal abscess on daptomycin, movement is not directly addressed in the provided studies 3, 4, 5, 6, 7.
- However, it is essential to consider the patient's overall condition and the potential risks and benefits of movement during recovery.
Retropharyngeal Abscess Treatment
- The treatment of retropharyngeal abscess typically involves surgical drainage of the abscess and intravenous antibiotics 3, 4.
- Daptomycin is a novel lipopeptide antibiotic that exhibits concentration-dependent activity, and high-dose treatment strategies have been explored 6.
- The management of retropharyngeal abscesses requires prompt diagnosis and treatment to prevent complications and improve patient outcomes 3, 4, 5.
Patient Care and Monitoring
- Intensive care nurses play a crucial role in preventing the deterioration of a patient's condition and improving patient outcomes 7.
- Nurses should be sensitive and attentive to each patient's unique situation, using a combination of medical knowledge, past experiences, and concentrated systematic observation to understand the patient's condition 7.
- Clinical practice should develop routines that enable nurses to be present at the bedside and work in a concentrated and systematic manner to provide safe care 7.
