Hi, I have an infected tooth. I have no insurance and since it has been the holidays and now it s the weekend, so I have not been able to get insurance in order to help me to get antibiotics or any dental help. I have had to use some antibiotics that were left in the rental home in which I live. I found a bottle of Cephalexin & since I just finished a half bottle of amoxicillin I wanted to take it, even though the swelling is somewhat better & so is the pain I am still having trouble. I looked up the Cephalexin and the medicine I have is not the same color as what I found online. With it being the weekend I have no hope of seeing a doctor & can t afford an emergency room. Could these pills just be a different color because, I think I heard that they change the color of medicine a lot. ??? Please help!
