• Gastrointestinal Disturbances: Patients may experience nausea, vomiting, diarrhea, or abdominal pain.
• Hematological Effects: Some patients may develop blood dyscrasias, such as thrombocytopenia or leukopenia.
• Renal Toxicity: In rare cases, these antibiotics can lead to nephrotoxicity, particularly in patients with pre-existing kidney conditions.

Poisoning

Poisoning by cephalosporins typically occurs due to overdose or inappropriate use of the medication. Symptoms of poisoning may include:

• Severe gastrointestinal symptoms
• Neurological effects such as seizures or confusion
• Renal impairment

Underdosing

Underdosing refers to the administration of an insufficient dose of the antibiotic, which can lead to treatment failure and the potential for the development of antibiotic resistance. This situation may arise due to:

• Patient non-compliance
• Miscalculation of dosages
• Inadequate prescribing practices
