Cephalexin, a widely used antibiotic, is generally considered safe for pregnant women, classified as FDA Pregnancy Category B. This indicates no evidence of fetal harm in animal studies, though human data is limited. It’s commonly prescribed for bacterial infections like urinary tract infections, with a reliable cephalexin supplier ensuring quality medication. However, it should only be used under medical supervision, as individual risks vary. Potential side effects include gastrointestinal upset or allergic reactions. Always consult a healthcare provider to weigh benefits versus risks, ensuring the chosen cephalexin supplier provides safe, effective treatment during pregnancy.
