Patients who are breastfeeding with a complication like appendicitis and opt for oral medication should apply broad-spectrum anti-inflammatory drugs. In the absence of allergy, β-lactam antimicrobials can be chosen, commonly used are amoxicillin capsules, amoxicillin dispersible tablets, and cefadroxil tablets. Because these drugs have a relatively broad antimicrobial spectrum and the concentration in breast milk is small, even if there is a certain distribution of the drug, it does not have much effect on the nursing infant. You can also choose macrolide antimicrobials, mainly erythromycin and roxithromycin capsules. And you should also eat a reasonable diet with few meals during the illness, stay away from stimulating foods, and keep bowel movements regular and smooth. Because some patients with appendicitis do not get better after conservative treatment, but have worsened symptoms, surgery is also needed.
