I want to know the answer to the following question:
Isoniazid is one of the two most popular drugs for TB treatment; what's the other one?
All the background I'm provided with is that "Directly observed therapy, i.e., having a health care provider watch the person take their medications, is recommended by the WHO in an effort to reduce the number of people not appropriately taking antibiotics.". Is that enough to answer the question?
Answer: no
