• Si tiene algún problema con el funcionamiento de sus riñones.

• Si está embarazada, esperando un bebé o en período de lactancia. Aunque no se sabe si la cefalexina es perjudicial para los bebés, es importante que informe a su médico si está embarazada o en periodo de lactancia.

• Treatment usually lasts 5-7 days, but your doctor may adjust this. Always follow their advice.
