after having a Csection and developing an infection the doctor prescribed flagyl. after taking this drug my daughter had a sever reaction with an oozing rash covering every inch of her face and scalp. Inside her mouth and lips were also affected. Subsequently i discontinued use of the drug and the rash started to clear up. however i have noticed that although i am breastfeeding exclusively the lovely glow that my child's skin had was gone as she is also gaining weight very slowly and i am concerned whether her exposure to this drug is responsible for that. Flagyl is a harsh antibiotic that usually cause reactions in adults, I am of the opinion that it should not be prescribed to breastfeeding mothers.
