Friend, at this dose cephalexin can cause crystals that damage the kidneys. For this reason it is best to try to induce vomiting and get it out of the stomach; need to move quickly before the pill moves out of the stomach. This is what you can do once you have the peroxide 3%:

1- Give her 1 teaspoon of hydrogen peroxide orally to induce vomiting.

2- Allow her to walk for a minute and move her belly to mix stomach content with peroxide. If she does not vomit within 5-10 minutes, repeat it again. Can give a total of 3 times 5-10 minutes apart.

3- If you do not see the cephalexin in the vomit or she does not vomit I would have her checked in to ER vet to start her on IV fluids and help the body metabolize and get rid of the cephalexin to protect her kidneys.
