It is typically administered orally once daily or as directed by a healthcare provider. It is important to complete the full course of treatment as prescribed, even if symptoms improve before the therapy is completed.

3. Adverse Effects

While Myambutol is generally well-tolerated, some patients may experience side effects such as gastrointestinal disturbances, visual disturbances, neuropathy, and skin rash. Regular monitoring by a healthcare provider is essential to detect any adverse effects early and adjust treatment if necessary.

4. Drug Interactions

Myambutol may interact with other medications, such as antacids, glucocorticoids, and other anti-TB drugs, affecting their absorption or efficacy. It is important to inform your healthcare provider about all medications you are taking to avoid potential interactions and ensure the effectiveness of treatment.

5. Efficacy and Clinical Studies

Several clinical studies have demonstrated the efficacy of Myambutol in the treatment of TB, both in drug-sensitive and drug-resistant cases. According to the World Health Organization (WHO), a combination of anti-TB drugs, including Myambutol, can effectively cure TB when taken as prescribed.

According to a survey conducted by the Centers for Disease Control and Prevention (CDC), TB treatment success rates have improved with the availability of combination therapy involving Myambutol. The use of Myambutol as part of a comprehensive treatment regimen has contributed to reducing TB-related morbidity and mortality worldwide.
