Pyridoxine supplementation is not routinely recommended for children receiving isoniazid but should be considered for exclusively breastfed infants, malnourished children or those with diets poor in pyridoxine, and children with HIV infection.

¶ Direct observation of drug administration is recommended. Intermittent therapy (2 or 3 times weekly) is not recommended for children with HIV infection.
