cephalexin
Cephalexin is used to treat certain infections caused by bacteria such as pneumonia and other respiratory tract infections; and infections of the bone, skin, ears, , genital, and urinary tract. Cephalexin is in a class of medications called cephalosporin antibiotics. It works by killing bacteria. Antibiotics such as cephalexin will not work for colds, flu, or other viral infections. Using antibiotics when they are not needed increases your risk of getting an infection later that resists antibiotic treatment.

Can taking cephalexin affect fertility or make it harder to get pregnant?

Does taking cephalexin increase the risk of miscarriage?
Miscarriage can occur in any pregnancy for many reasons. In a study of 262 people who took cephalexin during pregnancy, there was no increase in miscarriages compared with a similar group who did not take cephalexin. Talk with your healthcare provider about your individual situation.
Does taking cephalexin increase the risk of birth defects?
Every pregnancy starts with a 3–5% background chance of a birth defect, and information on cephalexin use in pregnancy is limited. In a study of 262 people who took cephalexin during pregnancy, there was no increased chance of birth defects above the background risk. Your healthcare provider can help weigh this information for your situation.
Can taking cephalexin during pregnancy cause other pregnancy-related complications?
Studies have not been done to see whether cephalexin increases the chance for pregnancy-related problems such as preterm delivery (birth before week 37) or low birth weight (less than about 2500 grams). Any questions about pregnancy outcomes should be directed to your healthcare provider.
Can taking cephalexin during pregnancy affect the child's brain development, learning, or behavior?
Studies have not been done to see whether cephalexin can cause behavior or learning issues for the child. Because this has not been studied, your healthcare provider is the best resource for discussing this further.
Is it safe to breastfeed while taking cephalexin?
Cephalexin passes into breast milk in small amounts. In reports of 20 babies exposed through breast milk, 4 had diarrhea, and one report describes a rash in a baby due to sensitivity to cephalexin. If a baby develops symptoms such as diarrhea or rash, contact the child's healthcare provider, and discuss any breastfeeding questions with your own provider.
