For Kidney Infections "Had a bad kidney infection, given MacroBID for 3 days. After 2 days, it wasn't working, given another 4 days' worth. After another 2 days, it still wasn't working. Called an online private doctor, prescribed Keflex 500 mg, 3 times a day for 7 days. Kidney infection calmed down after 2 days, wasn't sure if it was doing anything for bladder infection, still had pain and discomfort throughout the 7-day course. Side effects: severe itchiness, particularly on the torso. When finished with the course, still had bladder discomfort, but worse was the itch! 2 days later, the itch on the body was gone, but hands and fingers were still really bad, constant itching, scratching the skin raw. Read that Keflex stays in the system for 72 hours. Have had muscle pain throughout the course, which I am confused about whether the kidney infection is getting better as my back muscles hurt. No stomach problems. Can say Keflex sorted the kidney infection, not sure about the bladder infection."

For Skin or Soft Tissue Infection "I was taking Bactrim for 2 days with no improvement before being prescribed Keflex QID for 7 days to take with Bactrim for an infected cut on my wrist from punching glass. As soon as I began Keflex, I started noticing improvement. It's hard to say whether the improvement or my side effects were from Keflex or Bactrim, so take this with a grain of salt. I had tachycardia, chills, nausea, indigestion, gas pain that felt like chest pain, itching on arms/legs, petechiae on my upper arms, frequent urination, and eventual yeast infection for which I had to take Diflucan. I had some symptoms together, and some separate. Most of my side effects came at night, though, so it could've been some kind of reaction between the two? The side effects definitely hit me harder in the beginning, but by my 5th day of Keflex, almost all side effects had subsided. I suggest taking with probiotics that can survive stomach acid and easily digestible food and drinking a lot of water."

For Skin or Soft Tissue Infection "20 yo son took Keflex generic at 7 am Friday for a gross shin wound. After 3 doses, by Saturday afternoon, he had a fever of 102.6. The hospital deemed him COVID positive via a rapid test, though son only had a fever as symptoms of anything. The staff seemed excited to tell each of me, hubby, and my parents without son’s permission. Hubby and I each tested negative on non-rapid tests this morning. We will continue Keflex until the dosage is complete, but I would not take this med or allow my son to take it again. My mother is allergic to Keflex. It makes her itch and choke. I’m very certain the Keflex is causing my son’s fever, but COVID is a payday, so we just have to deal with it. He is allergic to amoxicillin."
