Metrogel while breastfeeding


I’m waiting for a call back from my ob and my daughters pediatrician. BUT has anyone used Metrogel while breastfeeding? I have it prescribed to me but after reading about it on the internet I’m not sure if I should take it. I’m EBF and she is almost two months old and never had a bottle and since she was diagnosed with being allergic to cows milk I don’t have a stash saved anymore. Just some advice would be helpful!!
