The vet prescribed cephalexin 500mg for my dog. Well, she died so... My husband gets ear infections on a regular basis. The doc gives him antibiotics. Well, we cant always afford the doc, no insurance, so I was wondering if my husband could take the cephalexin himself? The capsules are half dark green the other half light green and are imprinted ML-A08 500. I cannot find the pill on the pill identifier section.
