Breastfeeding is recognised as the healthiest way to feed a baby. Antituberculous drugs cross into the breast milk but the amounts are too small to produce toxicity. Women taking isoniazid should also take pyridoxine supplementation (14–25 mg/day). There are no reports of any adverse effects among infants of nursing mothers receiving anti-TB drugs . If a breastfeeding mother becomes acutely ill with TB, breastfeeding may have to be interrupted and breast milk expressed to prevent development of mastitis.
