The dosage of ethambutol and isoniazid is specifically determined by a person's weight, which is a critical factor in ensuring effective treatment and minimizing side effects. Both of these medications are commonly used in the treatment of tuberculosis and are weight-based to achieve the appropriate therapeutic effect.

Ethambutol's efficacy and tolerability can vary with body weight; thus, calculating its dosage based on the patient's weight allows for a more personalized and effective treatment plan. Similarly, isoniazid dosage also needs to be adjusted in relation to a patient's weight to avoid toxicity and ensure that sufficient levels of the drug are present to combat the TB bacteria effectively.

In contrast, the other drugs mentioned are typically dosed without direct reference to weight. Understanding the importance of weight in determining the dosage for these medications is crucial for safe and effective patient care in tuberculosis treatment.
