“Okay so now after nearly two weeks of getting diagnosed with a Kidney Infection and of me coming here to read the reviews (a lot of me crying) of how it works for everyone else. here is mine. I was taking one cephalexin pill 500 mg twice a day for 14 days I am on day 13; I didn’t start feeling better until day 4 which scared me because it seem that I was healing slower than others. I still had kidney pain at day 10 but now I don’t. This pill after 5 day’s made me sleepy and nauseous but that’s about it. I did find that on day 12 I started to pee out blood again but I knew it came from vagina by the discharge with it so I ended up getting BV with this pill which doesn’t surprise me it is antibiotic. So please know you may not feel better until four of five days every one heals differently. I wish you a speedy recovery :)”
“Taking two 500mg twice a day for a kidney infection, 28 year old female. I normally get extremely nauseated and dizzy on antibiotics. I do not on these, no side effects as of yet (day 3) I feel an improvement in my kidneys, but not as much as I had hoped at this point. I'm just happy I am not nauseated on these! I am eating Greek yogurt daily to avoid a nasty yeast infection from taking antibiotics. I do have to warn you, every time I open the pill bottle I get a strong bad smell. It's worth it to get some kind of relief from my angry kidneys! ”
“I had back pains for three days and unable to sleep comfortably. By the four day I couldn't even take a deep breath. I tried Salonpas along with back massagers and soaking. Nothing helped! I went to the E.R. urine test revealed elevated white cell .They prescribed me cephalexin 500 mg three times a day. I was in so much discomfort I started the medication immediately! I felt 100% better the very next day. I have been drinking water and cranberry juice.”
“I took cephalexin to treat a UTI. I started to get really bad anxiety out of nowhere. It started on the second day (I took this antibiotica over 7 days) and the panic attacks stopped after about 3 weeks since I took them for the first time. I even got them at night. Besides that I started to shake in my upper body after a couple hours of taking a pill.”
“Taken two rounds of antibiotic cephalexin for a UTI. Whilst it does appear to be helping the infection, I’m depressed, jittery, severely anxious, joint and muscle aches , dehydrated and sunken eyes!!! Nightmares and adrenaline. It is so awful. I cannot wait to finish this drug.”
“I’m a healthy 20 year old female who took this drug for about 4 days before having to call it quits. I’m 9 weeks pregnant at the moment. Not sure if that was making this worse or not, but I had the WORST fatigue I’ve ever experienced. I was physically unable to get out of bed other than to use the bathroom and shower. My body felt extremely heavy and I was very confused and out of it. It make me nausea I was already experiencing 10 times worse. I ended up having a severe episode of heart racing for about 10 minutes on the 4th day. Blood pressure shot up to 150 and pulse got high. I threw this away. Listen to your body. I know it’s important to finish medications but when the side effects are this bad this is dangerous. Since my urine has completely stopped burning and it’s clear again, I have made another appointment with my doctor to confirm my infection is gone. Home tests came back negative. If not, I will request something else because this was AWFUL.”
“I am on day 2 of Keflex for a kidney infection from an untreated urinary tract infection. I am allergic to most antibiotics such as amoxicillin and erythromycin so I was hesitant to try this. I am so happy to say I have no allergic reaction and no diarrhea! I do feel some tingling sensations in my head and a tiny bit of anxiety (probably all in my head) but nothing compared to an antibiotic like Levaquin. I think I found my new go-to antibiotic!”

Keflex (cephalexin): “Had bad kidney infection, given MacroBID for 3 days, after 2 days wasn't working given another 4 days worth. After another 2 days still wasn't working called online private doctor prescribed Keflex 500mg 3 times day 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 7 day course. Side effects severe itchiness particularly torso. When finished course still had bladder discomfort but worse was itch! 2 days later the itch on body gone but hands and fingers were still really bad constant itching, scratching skin raw. Read that Keflex stays in system for 72 hours. Have had muscle pain throughout course which confused about whether kidney infection getting better as back muscles hurt. No stomach problems. Can say Keflex sorted kidney infection not sure about bladder infection”
“I drove 2000miles pain in my side, back and groin. I thought I was just feeling the effects of the drive.Then the pain got so bad I could barely move without screaming out. I was rushed to hospital and found out one of my kidneys was severely infected. They told me it was most likely from an untreated UTI. I never had any symptoms of a UTI and said it was a very small part of my kidney. They kept me overnight. I never had a fever. They gave me a strong dose of cephalexin twice through my IV, ,and sent me home with 500mg 4 times a day. By day 4 I was completely out of pain, but had a real bad rash covering my torso. It didn't bother me much. I'm into day 5 stopped taking it yesterday, but the rash has now spread to my legs. I'm going to give the drug time to get out of my system to see if that improves my condition.”
“I got put on cephalexin for an untreated UTI which obviously spread to my kidneys, I am current on day 3 and I do feel so much better kidney pain and urinating wise, but it gives me insane dirrahea, makes me feel very nauseous, makes me confused with really bad anxiety, and gives me killer heartburn. I am currently on 500mg 4 times a day”
“Absolutely horrible experience with this cephalexin medication, I was prescribed a dose of 500mg 4 times a day, for 10 days, for a kidney infection. After the first 2-3 days I started to have some chest pain and shortness of breath, I chalked it up to my asthma and tried to power through. But on the 8th day my chest pain was so bad I had to make a trip to the ER. On op of that it made me extremely nauseous.”
“Have been using CefALEXin for 2 days now due to a UTI which started on a monday, then got worse and spread to a kidney infection by tueday then had all the symptoms by tuesday night and started taking CefALEXin Wednesday afternoon, started working the next day, although i get random sever headaches, feel dizzy when standing, feel nauseous in the morning and with no appetite, but that will go once I've finished these antibiotics. I'd much father be feeling like this than how i felt with no treatment on the kidney infection :)”
“56 year old male, I unknowingly had a kidney infection, my first symptom was aural hallucinations, that became more frequent and louder over several days, before I went to ER. While hospitalized overnight, and the doctor thinking I had a “mental” issue, the infection finally caused me having difficulty being able to urinate, and pain when I finally was able to get some flow going. The doctor then said I had a UTI/kidney infection (rarer in men that women) pretty common in elderly women including the hallucinations. I was sent home with Cipro, it somewhat stabilized the infection, but and reduced it’s symptoms, but didn’t rid me of it. Then went on Keflex 500mg 3x a day, for 14 days. By day 2, hallucinations were gone, day 3 no obvious symptoms, I took the full course of 14 days, and everything is great. I had some mild side effects, but compared to aural and some visual and tactile hallucinations, side effects were nothing.”
Keflex (cephalexin): “I had a bad kidney infection and was prescribed this in the ER to take 3 times a day for 7 days, I hardly had any side effects at all. The only ones I had were a yeast infection, really bad nightmares, and some sneezing. Other than that I love this and would definitely take it again, kidney pain was gone within 2 days.”
“I’ve been taking this medication on and off for about 5 ish years for bad UT/kidney infections. I’ve had it in liquid form and in pill form however I can’t take pills so I crack them in apple sauce. Smells like rotten eggs but I can tolerate it. Doesn’t taste that bad. I don’t have dizziness, no diarrhea. When I have an infection, I always feel better while I’m on this medication. I don’t feel bad while on it. It’s a big relief. I can take this on an empty stomach with no stomach issues and let me tell you, I’m SENSITIVE and I have a screwed up gut and it doesn’t bother my gut. I’m a small girl 4’11 petite and I usually take 1 pill 4 times a day. Now the only issue I get is yeast infections but that’s common. I’d take yeast infections over having stomach problems any day. This is my go to antibiotic because it just does the job.”
“I had just taken Diflucan for what I thought was a yeast infection. Then I got a sinus infection and I started taking cephalexin. I noticed 3 days in, some back pain (flank pain just to the left if my spine) I had been having for a few weeks suddenly went away. I went back to the doctor, who agreed that I probably originally had a bladder infection that spread to one of my kidneys. Glad I got the sinus infection or who knows what would have happened. The medication made me feel a little nauseated after the first few days, but it's possible that feeling was related to the sickness.”
“I felt woozy for a couple of days. Then, I had stabbing pain in my side that radiated to my lower back. Doc diagnosed me with a kidney infection and put me on Cephalexin. Despite the meds, back pain and side ache felt horrible. I continued to take the meds despite feeling tremendously nauseous, even dry vomiting once, feverish, cold chills and no appetite. The thought of food made me retch. Kind of thought I could die. I drank lots of lemon infused water. After the 7th dose, 36 hours from the first pill, I was no longer in pain or nauseous. I had a migraine but the doc told me to avoid coffee and and once I had a cup of coffee the migraine went away, too. Four days later and I'm good as new but I'm going to continue taking the meds. I'm on 250mg 4x a day for 7 days. I suspect the medication is making my muscles tense and I am not sleeping well, just 5 hours a night. 4x a day is a hassle. I was tempted to take 500 mg 2x a day but I didn't want to risk a set back.”

“Went to the ER Sunday for pain in back, constant feeling of needing to pee, pain when urinating, and blood in urine. Diagnosed with a Kidney infection and was prescribed 500mg of Keflex 2x a day for 10 days. Since then there isn’t anymore blood or pain when I pee. I also don’t have to go every 2 seconds but it’s day 4 and I’m having some wicked side effects. I am exhausted. I still definitely have the infection (had a follow up appointment already) so that could be contributing to the tiredness but I’m falling asleep every 2-3 hours. First 2 days I had terrible diarrhea but now I’m constipated. The stomach cramps are also really not fun. Taking lots of Advil to help with that. I haven’t been able to work due to these side effects and the symptoms from the infection. But the meds are working, getting rid of one symptom at a time.”
“I was recently prescribed cefalexin 500mg for a kidney infection and 3 days into taking it the skin on my face has gone extremely dry and my eyes are really puffy and swollen. Though they have cured the Infection I'd feel very apprehensive about taking it again.”
“I went to the ER for a kidney infection and they prescribed me Cephalexin for 14 days. I am currently on day 10 and my kidneys still hurts my side effect symptoms are diarrhea and feeling light headed at times also stomach bloating and pain. I reviewsed it with my doctor and she said to continue to the 14 days. I will come back for a final review”
“Had cephlaxen through IV and now on day 3 of ten days twice a day oral tablets. 500m for kidney infection I'm also pregnant. I usually react horribly to antibiotics, this one so far is not so bad all my symptoms relieved after second day, I do have headaches from this med and sensitivity to light. But so far so good. I recommend it but it gets a lower rating due to My headache :(”
“i was in terrible pain in my kidneys, so I had to go to the ER and I got diagnosed with a kidney infection. I got prescribed with cephalexin (500mg 4 times a day) (mind you, I'm a 19 year old girl) it made everything worse. I don't wanna get out of bed because of how much pain I'm in. This med has been terrible. I've got a UTI, tired 24/7, not feeling any better.”
“Was put on cephalexin for a UTI 500mg twice a day for 7 days have just finished it after a horrendous experience. Very bad indigestion, anxiety, diarrhoea first day then constipated. Fatigue and headache. Shakes with hot and cold periods. After a day of finishing the diarrhea has returned will never take this medication again.”
“I've had many UTIs before and they normally give me Cipro- which works great for me. My doctor told me that Cipro apparently causes tendon rupture so they gave me cephalexin antibiotic instead (amoxicillin does nothing for me anymore). Cephalexin makes me so exhausted that I'm now sleeping almost all day and have started missing my alarms to take it again! I'm on the 3rd day and I'm barely feeling better (I'm taking it 2x a day every 12 hour for 7 days at 500 mg.) Not to mention it's giving me unpleasant dreams and making me SO itchy! I'm not sure if I'm accidentally overdosing myself to try to catch up on missed doses and causing these side effects or what... but after this round I'm requesting that they NEVER give me these antibiotics again!”
“I am a 59 yr old female and was diagnosed with a kidney infection. One week prior I had minor UTI symptoms two random days for an hour or so. One week later I was rushed to ER temp 103.2 severe shivering and shakes and flu like pains. Now I'm on On cephalexin 48 hours. No fever at all. Extremely bloated. Slightly nauseous, abdominal pain, minimal body pain. Knocked fever right out. This stinks, but I think this was a great call on the antibiotic. I'm taking it 3x daily 500mg”
