Clinical Presentation

Overview of Rifampicin

Rifampicin is a potent antibiotic that works by inhibiting bacterial RNA synthesis. It is commonly used in the treatment of tuberculosis and certain other infections. Underdosing occurs when a patient receives less than the prescribed amount of the medication, which can lead to suboptimal therapeutic effects and the potential for treatment failure or resistance.

Signs and Symptoms of Underdosing

The signs and symptoms of underdosing rifampicin can vary based on the underlying condition being treated and the duration of underdosing. Common manifestations may include:

• Worsening of Infection: Patients may exhibit signs of persistent or worsening infection, such as fever, chills, and malaise, indicating that the antibiotic is not effectively controlling the bacterial load.
• Increased Symptoms of Tuberculosis: In cases where rifampicin is used for tuberculosis, symptoms may include a persistent cough, hemoptysis (coughing up blood), night sweats, and weight loss.
• Fatigue and Weakness: Generalized fatigue and weakness may occur due to the body's ongoing struggle against the infection.
• Laboratory Findings: Blood tests may show elevated inflammatory markers, such as C-reactive protein (CRP) or erythrocyte sedimentation rate (ESR), indicating an ongoing inflammatory process.

Patient Characteristics

Risk Factors for Underdosing

Several patient characteristics may predispose individuals to underdosing of rifampicin:

• Non-Adherence to Treatment: Patients may not take their medication as prescribed due to forgetfulness, misunderstanding of the treatment regimen, or side effects.
• Complex Medication Regimens: Patients on multiple medications may struggle with adherence, leading to missed doses.
• Socioeconomic Factors: Limited access to healthcare resources, including medications, can contribute to underdosing.
• Cognitive Impairments: Patients with cognitive impairments or mental health issues may have difficulty following complex treatment plans.

Clinical Considerations

Healthcare providers should be vigilant in monitoring patients on rifampicin therapy for signs of underdosing. Regular follow-ups, patient education on the importance of adherence, and simplifying medication regimens when possible can help mitigate the risk of underdosing.

Conclusion

Underdosing of rifampicin, as indicated by ICD-10 code T36.6X6, can lead to significant clinical consequences, including treatment failure and the development of drug resistance. Recognizing the signs and symptoms associated with underdosing, along with understanding patient characteristics that may contribute to this issue, is essential for healthcare providers. By addressing these factors, clinicians can improve treatment outcomes and enhance patient adherence to antibiotic regimens.
