Underdosing of Antimycobacterial Drugs: A Potential Sequela

When it comes to treating mycobacterial infections, such as tuberculosis, leprosy, or non-tuberculous mycobacterial diseases, the accurate and appropriate dosing of antimycobacterial drugs is crucial. Unfortunately, underdosing of these medications can lead to several unfavorable consequences.

Underdosing occurs when patients receive a lower dosage of antimycobacterial drugs than what is recommended. This can happen due to various reasons, including poor adherence to treatment regimens, incorrect prescription, or inadequate drug availability. Regardless of the cause, underdosing can significantly impact the efficacy of treatment and may lead to the following sequela:

1. Drug Resistance: One of the most significant risks associated with underdosing is the development of antimicrobial resistance. When the dosage of antimycobacterial drugs is insufficient, it fails to effectively kill all the bacteria, allowing the surviving microorganisms to mutate and become resistant to the drugs used. This can lead to the emergence of multidrug-resistant tuberculosis (MDR-TB) or extensively drug-resistant tuberculosis (XDR-TB), which are much more challenging to treat.
2. Disease Progression: Underdosing can also result in the inadequate suppression of mycobacterial growth, leading to disease progression. When the bacteria are not fully eradicated, they continue to multiply and spread, causing further damage to the affected tissues and organs. This can result in prolonged illness, increased morbidity, and even mortality.
3. Prolonged Treatment Duration: Insufficient dosing can extend the duration of treatment required to achieve a cure. When the bacteria are not effectively killed, it may take longer for the immune system to control the infection. This can lead to prolonged treatment periods, increased healthcare costs, and added burden on the patient.
4. Inadequate Symptom Relief: Underdosing may fail to alleviate the symptoms associated with mycobacterial infections. Patients may continue to experience persistent coughing, fever, night sweats, weight loss, and fatigue, affecting their overall quality of life.

Therefore, it is of utmost importance to ensure that patients receive the correct and adequate dosage of antimycobacterial drugs during treatment. Healthcare professionals should closely monitor patients' adherence to prescribed regimens, provide clear instructions, and educate them about the potential consequences of underdosing.

By addressing the issue of underdosing and promoting appropriate drug administration, we can enhance the effectiveness of antimycobacterial treatment, prevent the development of drug-resistant strains, and improve patient outcomes.
