For Skin or Soft Tissue Infection "Works very well for treating the cellulitis I got from an insect bite. But don't drink alcohol while you are on this medication. I had half a beer and started feeling really nauseous, had a migraine and my stomach hurt."

For Bladder Infection "I have constant battles with UTI’s so I’ve taken a lot of different antibiotics. Keflex is definitely a good one but for me I have to take 500 mg three times a day so I get some side effects, mostly tired, stomach cramps and dizzy. It’s not bad though like some of the other ones I’ve taken. Before I had repeat infections I had the 500 mg twice a day dose and had very minor cramping from that dose. It’s my go to when I can take it. Drink lots of water with it too, it helps flush your system faster and get rid of the infection and it’s side effects quicker."

For Bacterial Infection "I have used this medicine for years for many different conditions including bronchitis, boils, bladder infection, sinusitis among a few others. The problem though has become since I have used it so many times, I am almost resistant to it and need a larger dose or longer dosing schedule to clear up a more severe case of the ailment. When it works, it works well."

For Skin or Soft Tissue Infection "I've been prescribed this antibiotic many times. I just realized that with my current course for a skin infection that I sweat profusely when I take this. The last time I had episodes of profuse sweating was the last time I was on this! I don't see it listed anywhere as a side effect, but it seems to happen to me every time I take it. "

For Bacterial Infection "I was prescribed Keflex for an infection that occurred after root canal went bad. Evidently, the previous dentist had not been able to successfully remove all of the nerve and pulp, and over time an infection resulted. Keflex was well tolerated by me and helped to reduce the swelling within the gum until I was able to have a root canal retreatment in order to remove the rest of the nerve and pulp. The rating that I provided is due to the fact that this medication required 4 doses daily, which I felt there must have been some other medication available that required less commitment. Still, it did work and I would take it again if prescribed."

Infection cleared but I am left with side effects of pains in legs, hands, thighs, toes, fingers and really sore shoulders into spine and ribs. Didn’t have these pains prior to taking this drug. Jaw started clicking as well. Never again."

For Skin or Soft Tissue Infection "Keflex is a literal lifesaver. I get really serious skin infections that progress to cellulitis and it’s the only thing that treats them effectively with no noticeable side effects. I just had surgery and got very sick from a UTI from the catheter. I started taking keflex instead of other drugs and felt better within a day. Genuinely if you have bad side effects from other antibiotics, this is definitely worth a try."

For Kidney Infections "This is an incredible medication, I regret not taking it sooner due to listening to bad reviews on this website. It is a great medication and very effective on getting rid of bacterial infections of the urinary tract, skin, even ear infection. I had only one side effect and it was slightly full stomach I did not have nausea nor did I vomit or anything of that nature. How I experienced NO discomfort. I’m not a doctor but many people including myself have used real life experience to conclude the way to use this medication with no side effects. Not telling anyone what to do but this is what I did, I ate a cup of rice before every dose so that my stomach did not become irritated and it worked. I also drank 8 oz of water with it. Lastly, 2 hours AFTER dosing I took a probiotic called Culture from CVS, it contains LGG which is a bacteria that is helpful for the gut and keeps you from having diarrhea very effective! You guys need to get this probiotic it works so well."

For Skin or Soft Tissue Infection "I get recurring cases of impetigo and Keflex is always my go-to drug. Keflex clears up the infection quickly, and I've never experienced any side effects, even if I take it on an empty stomach. Highly recommended!"

For Skin or Soft Tissue Infection "I fell off my longboard and made some bad dressing decisions. After 3 days I saw a doctor who prescribed this and silver sulfadiazine. After 10 days it completely healed. Unfortunately I have had another tumble, this time with broken wrist and 10 open wounds. On it again. Trusting old Keflex to help again."

For Upper Respiratory Tract Infection "Being a person with cancer in remission and following health problems- COPD, Bronchiectasis, Chronic Bronchitis, Emphysema, Chronic Sinus and ear infection, odd UTI at odd times. I passed out during the night and woke up on the floor and could not get up off the floor or walk - not Covid. After roughly four to five trips by ambulance to hospital and various drug treatments with relapses now and again my GP put me on low dose 250 mg Keflex to take one tablet every night and since that day have never had to go back to hospital or have not passed out again. So possibly l may now be helped with bacterial infections, and I can only speak of my personal experience but for me this is a wonder drug. I do realize that bacteria become immune to antibiotics but as far as I know I have had no adverse side effects. Antibiotics have come a long way, since I was a child. My age is now seventy nine years of age. I do not have diabetes or heart problems, mainly lung problems and do not smoke."

For Bladder Infection "I have been going back and forth battling a UTI for about a year. I take D-Mannose, which usually knocks it out in a day or so but the D-Mannose has been giving me weird pains in my carotids... Anyway, I decided to go get a script after waking up with severe bladder pain a few days ago. About six hours after the first dose, the pain subsided. This medication will make you nauseated if you don't take it with at least 6oz of water and a snack. No negative side effects yet! Love Keflex!"

For Skin or Soft Tissue Infection "I have suffered with ulcers on my ankles (poor circulation) for years. Every once in a while one if not both will get infected. Legs swell and skin turns purple as well as becoming very sensitive. The ulcers feel as though hot pins are being shoved into them. Keflex always knocks out the infection within a few days."

Blurred vision, dizziness, rash, leg pain and swelling, heat sensations in legs, muscle pain, back pain, swelling and pain in stomach, and extreme fatigue.

For Bladder Infection "I've always taken ciprofloxacin for my chronic bladder infections, but this time around my doctor said he can't give it to me because of a new study that has nothing to do with me. So.... I get Keflex. It's extremely slow at getting to the infection. I'm on day three and I'm just now starting to feel a little better... I think. It also gives me horrific heartburn, headaches, fatigue and I can't poop."

For Acne "I started taking this medication initially for an infection from a bug bite. After three days of being on the medication I noticed all of my skin is clear and appears to be glowing and my pores have shrunk so much . I’m in my early 30s and still suffer from acne occasionally mostly hormonal acne and this is amazing I don’t want to get off of it now. I was on doxycycline for months in my early 20s which also had similar effect. The only side effects from this medication initially was a headache and diarrhea but that went away after one day and I’m staying on probiotics to help regulate ."

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."

For Bladder Infection "I have been prescribed Keflex since they stopped using CIPRO for that a few years ago. Works great every time and works within hours. Makes me a little tired and a have a bit of a headache, but I think that might have to do with body trying to heal itself. I always ask for it if it will treat the bacteria that caused my UTI. They won't prescribe this for some bacterias...fyi. I like that this drug has been around for years and years. Makes me feel safer abut taking it."

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.

For Bacterial Infection "Hubby has a bad tooth, recently started hurting him extremely bad. Got hold of a dentist to get the tooth out. He prescribed keflex 250mg, for first 3-4 doses he was to take 2 x 3 doses then 1 cap x 3/day until finished. Within 1 dose, his tooth pain went away however on 2nd to 3rd dose the nausea, vomiting, horrible stomach pain that he describes as a nasty pain which he has to make himself puke which gives him short term relief. So if he is able to tolerate the rest of the duration of the script, this will be added to his list of meds he can't take"
