Amoxicillin falls under Pregnancy Category B which means it may be acceptable for use. In this case animal studies show no risk but human studies not available. If you are pregnant, suspect you are pregnant or are planning to become pregnant, it is important to discuss this with your doctor. They will help you to weigh up the benefits and risks of pregnancy with amoxicillin. Amoxicillin should not be used during breast-feeding as it can pass into breast milk in small amounts and cause diarrhea, as well as a fungal infection of the mucous membranes. For this reason, weaning is recommended, especially with high doses. With a lower amount of amoxicillin, you should consult your doctor to decide whether breast-feeding with amoxicillin is possible for you.
