Abdominal pain following intravenous benzyl penicillin administration
Abstract:
The occurrence of abdominal pain (in three patients) and lower chest pain (in one patient) either during or immediately after the intravenous administration of high doses of benzyl penicillin is reported. All four patients were diagnosed as having bacterial endocarditis and had been receiving between 8 and 18 mega units of the drug per day for 2--3 weeks, when the symptoms were first noticed. A skin rash also appeared in each case, at this time. Both the rash and abdominal pain disappeared when an alternative antibiotic was substituted for the penicillin.
Insights
High-dose benzyl penicillin can cause abdominal pain and skin rash in bacterial endocarditis patients. Symptoms resolved after switching to an alternative antibiotic, indicating a potential adverse drug reaction.
Area of Science:
- Cardiology
- Infectious Diseases
- Pharmacology
Background:
- Bacterial endocarditis is a serious infection requiring aggressive antibiotic treatment.
- High-dose intravenous benzyl penicillin is a common therapeutic agent for bacterial endocarditis.
Observation:
- Four patients with bacterial endocarditis developed abdominal pain and/or lower chest pain during or after high-dose benzyl penicillin infusion.
- Concurrent skin rash was observed in all affected patients.
- Symptoms emerged after 2-3 weeks of continuous high-dose therapy (8-18 mega units/day).
Findings:
- The adverse events, including pain and rash, were directly linked to high-dose benzyl penicillin administration.
- Discontinuation of benzyl penicillin and substitution with an alternative antibiotic led to the complete resolution of symptoms.
Implications:
- Clinicians should be aware of potential adverse reactions to high-dose benzyl penicillin, particularly gastrointestinal and dermatological symptoms.
- Prompt recognition and management of these side effects are crucial for patient well-being and treatment adherence.
- This highlights the importance of monitoring patients for adverse drug reactions during prolonged high-dose antibiotic therapy.
