Clinical Description

Definition of Underdosing

Underdosing occurs when a patient receives less than the prescribed or recommended amount of a medication. This can lead to suboptimal therapeutic effects and may result in treatment failure, particularly in the case of antibiotics where adequate dosing is crucial for effective infection management[1].

Cephalosporins and Beta-Lactam Antibiotics

Cephalosporins are a class of antibiotics that are structurally and functionally related to penicillins. They are commonly used to treat a variety of bacterial infections. Beta-lactam antibiotics, which include both cephalosporins and penicillins, work by inhibiting bacterial cell wall synthesis, making them effective against a wide range of gram-positive and gram-negative bacteria[2].

Clinical Implications of Underdosing

1. Increased Risk of Resistance: Inadequate dosing can lead to incomplete eradication of bacteria, which may promote the development of antibiotic resistance. This is particularly concerning in the context of cephalosporins, as resistance can limit treatment options for future infections[3].

2. Treatment Failure: Patients may experience a resurgence of infection or prolonged illness due to insufficient drug levels in the body. This can lead to complications, increased healthcare costs, and the need for more aggressive treatments[4].

3. Patient Factors: Underdosing can occur due to various factors, including patient non-compliance, incorrect dosing calculations, or miscommunication between healthcare providers and patients regarding the medication regimen[5].
