CDSCO has ordered new warnings on two widely used medicines — doxycycline and carbimazole — after adverse reactions were flagged. Doxycycline must now carry cautions about restlessness, anxiety, irritability, nervousness, and dizziness. Carbimazole labels will warn of agranulocytosis, a potentially fatal drop in WBCs. Manufacturers must update inserts, with patients advised to stay vigilant.
