What can i take for a cold and sore throat if breast feeding?

It depends...: There are multiple forms of otc cold and congestion medicines. Certainly you should check with your pediatrician or ob-gyn first before taking any medication while breast feeding or while being pregnant. However, as a general rule, most breastfeeding mothers may safely take guaifenesin-only products. Determine if the product contains aspartame, as this has been associated with headaches.
