"After very minor foot surgury, I was put on 500 mg Cephalexin 4 times per day for a week. After 4 days my digestive system went septic and I had to quit the medication. I seldom take even over-the-counter drugs and have never had a reaction this severe to an antibiotic before. I thought I would get back to normal after a week but after 3 more weeks my digestive system has not imporved. I have scheduled an appointment with another doctor in hopes of regaining my normal health."

"I’m currently on my 5 th day of cephelaxin 500 mg 4X a day . I have an abscess from shaving with a dull razor and not using shaving gel, that’s what I’m thinking anyway. Anyway, this antibiotic is really messing me up. I’m anxious, paranoid around people, super irritable, I feel scared in general. My stomach is distended and I’m constipated and retaining water. I want to stop but I’m scared to. I’m going to call my dr. Thanks every one for posting about your experience. Helping Me a lot"

"I was going through severe anxiety, heart palpitations, tachycardia, body numbness, going in and out of another world. I had new allergys, twitching when I would almost fall asleep, 21 ER visits later I found the answer. The antibiotic I was on for tooth infection caused severe ulcers all threw out my GI track, it can cause all of that. I almost had a couple heart attacks before I realized this. Here is what my treatment is consisting of, beta blockers to control the heart palpitations ( you need them or it will get bad) Ativan to control the anxiety (this too will get worse) Steroids to fix your mental state, reduce intestinal swelling, and get your immune system back on track so your allergies stop (this too will get worse) and a PPI pill to stop the stomach acid so they can heal. Also I'm waiting for a scope treatment from a Gastro Doctor. I'm hoping I can make it until then but for anybody else experiencing what I did please get it addressed ASAP, I was told by every doctor it was anxiety and even banned from a ER"

"I suffered a urinary tract infection a week ago and went to the doctor when they prescribed me Clindamycin 300mg 3 times in 3 days and Cipro 500mg every 12 hours. I couldn't take either of them because I can't swallow big pills, and I'm afraid Cipro is a little strong for me. I get real anal when it comes to taking medicine like this, for I have a fear of side effects and haven't taken antibiotics before. I went back just the other day and switched medicines and I'm taking this, a liquid form 250mg every 6 hours in four days for 10 days. It taste really good and it smells good, looks like Pepto Bismol. I always take it with food and I have no side effects, and so far it's working great! I highly recommend any one to take this medicine that suffers urinary tract infection."

"I am currently using this medication to fight a staph infection. I'm not sure how I got it but it seemed to start from a bug bite of some sort. The infection was the size of a golf ball and had lightening streaks running up my arm. The doctor had to cut open my arm and clean out the pus. Well it's been about a week and the infection has cleared up. Cephalexin seemed to work very well. I have no side effects and I'm feeling great."

"I started taking Augmentin for a bad sinus infection. I got to the last 3 doses, when I went to see my pcp, & I told her I didn't feel any better. She prescribed cephalexin 500 mg twice daily. My sinus infection was gone within two days. I took probiotics with it the entire 10 days & after the last dose, took 2 Diflucan. It worked great for me."

"Brilliant drug. I like it so much better than Cipro. Worked fast, no problems at all. I hope to use it again if there is another UTI. I feel like my old self again, and there are a few left to take."

"I had a combination of an infection after an extraction as well as skin infection that hurt very bad (both things). I was prescribed 500 mg of cephalexin every 6 hours. By the second day they were both feeling so much better. I was hesitant because I've had allergic reactions of other Antibiotics and a severe reaction to bactrim. Thankfully nothing like that with this medication, but it does cause a very inconvenient stomach upset that causes me to have to get to the bathroom in a hurry throughout the day. I have noticed I'm more tired, I'm not sure if that's a side effect from the medication alone or because of having to use the bathroom so often. But, I push through the negatives because it has done wonders for the infections."

"I had a hair follicle infection on the top of my head and the bump from it being infected got to be the size of a ping-pong ball and so they put me on 500mg of Keflex 4 times a day. It took 4 days for the medicine to take effect and it totally wiped the infection away. At first I didn't think it was going to work I had pus and blood coming out that thing it was totally gross and this drug is a miracle drug if you think about a hundred years ago people would die from stuff like that"

"I started this cephalexin antibiotic to prevent infection after having a tummy tuck. After three days I developed dizziness/vertigo, slight confusion and being tired. It felt almost like I slept in too much all the time, kind of foggy. At first I hashed it up to the major surgery I just had but after awhile I started to panic. I called the surgeon’s office and they recommended that I come off of the pain meds I had been given. It’s been days without pain meds but I’m still feeling really out of it and dizzy. I found that this could be a symptom of this antibiotic. I took my last one today so I will be back to update everyone on whether it goes away or not. I really hope it does."

"I'm a healthy female in my mid-60s. On February 2020 I came down with a flu-like cold that got incrementally worse. Initially, my doctor prescribed Amoxicillin but it didn't work at all. I continued getting high fever at night and coughing constantly. After 6 weeks of this I returned to the doctor and this time he prescribed Cephalexin for 10 days. After the 2nd dosage I felt 100% better. It was like taking a miracle drug. I didn't experience any side effects. I will always insist on this antibiotic because it works. I paid for my prescription out of pocket: $10.61 for qty. of 30."

"It was effective in handling the infection in my teeth but approximately 3 weeks after finishing the second course of it, I have developed the annoying vaginal itch and discharge. I am post menopausal and was pretty sure the cephalexin was the culprit."

"I was prescribed 500 mg every 12 hours for ten days to fight a bacterial problem stemming from a stye on my eye. The cephalexin is working after 2 days however it makes me itch; no hives just mild itching. I make sure I take it with lots of water and I am eating yogurt to make sure I do not get a yeast infection. If the itching worsens I will obtain a different antibiotic. I am sure there is something else that won't make me itch. I had some other antibiotic when I had a root canal that did not make me itch."

"Okay, so I recently had ovarian removal of my left ovary at the beginning of the month. Fast forward about three weeks and I see that my belly button which was one of the areas they went in through, had a pool of puss in it (Even though I had no fever nor did I really have any redness or swelling) But I thought it would be better to be safe than sorry so I went to the ER. The doctor barely looked it over, acted like he didn't even want to be there, and then sent his nurse in to prescribe me this garbage antibiotic cephalexin. I am going on day four and I'm done. There's no way I can continue this medication for 7 days. It in a short amount of time has already made me incredibly dizzy and fatigued, but has given me horrible stomach aches that come and go, diarrhea, and a feeling like I'm about to faint. It looks like the infection is gone and if it's not then I will go to my primary care doctor and have them prescribe me something else."

"I took it for ten days for a skin infection. Cleared it up in ten days. Despite taking so many probiotics and eating yogurt, I got severe diarrhea and I STILL have mild diarrhea. Also, if you're a woman, be prepared for a yeast infection. It's driving me insane."

"Took this drug and got the following results: a dislocated hip; a tear in the tendon of my right foot and hands and thumbs that are inflamed and very painful. It affected my joints and tendons. The literature does not recommend for women over 60 or on Metformin. Stay away from this drug. It can be devastating."

"drug works, but it can nearly kill you. Side effects for me were same as heart attack. If your allergic It can kill you. Take at your own risk. If you are allergic to penicillin DO NOT TAKE IT. Dr will tell you only 1-10% of people show reactions, but you could be that 1 % and be dead too. It was a bad experience."

Keflex (cephalexin) "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"

"I was prescribe this for a UTI. On the 3rd day of using this I got vaginal itching and extreme dryness! I'm on my 2nd day of my period (which is heavy on these days!) and I'm so dry my period stopped! I feel horrible and irritated down there. Stay away from this medication."

"I got prescribed cephalexin 500mg 4x daily for a minor bacterial infection. At first I was fine, was just a little drowsy. However as the days passed I started becoming INSANELY paranoid, delusional, and depressed. I actually hallucinated as well as cried every single day several times a day. This drug cephalexin is absolutely horrible and I will never be taking it again."

"I have asthma and have had respiratory problems my whole 27 years. When I get sick, I get sick as a dog for long periods of time. Needless to say, I have been prescribed to several different antibiotics over the years and each of them helped. However, everytime I have taken cephalexin I have noticed an almost immediate result. So immediate that it is shocking. Currently, I am prescribed 500mg 3x per day for 10 days and I haven't had any side effects aside from feeling tired but every antibiotic does that to me. Cephalexin is by far the best antibiotic I have had. Everyone reacts differently though so we all have to find which medications work best for our bodies."

"Horrendous stuff. Foul smelling, stomach-churning, nausea-inducing, ugh. It made me feel I was on board a ship in a typhoon, retching hourly. I don't know how people take this. I will NEVER take this again if i can be prescribed something else that works. I have some positive experience with the healing of the toenail but at what foul cost?"

"I was prescribed a 10-day 500mg cephalexin series for a staph infection that manifested as a purplish ruptured boil on my side. I dreaded taking them because I've always gotten extremely sick on antibiotics. However, I'm one pill shy of halfway through, and I haven't had any side effects except maybe feeling hotter than usual (despite having a low body temp), but that may or may not be the antibiotic since I naturally feel hot all the time anyway. The site of the staph infection is healing very nicely. I'm honestly shocked that this antibiotic isn't making me sick. Based on the other reviews I see on there, it looks like different people are sensitive to different families of antibiotics, so you'll just have to work with your doctor to find the one that works for you when you need to take them!"

"I was prescribed Cephalexin for infection after my hysterectomy. I started taking it on a Thursday. By Saturday night/Sunday morning I had a frightening case of Vertigo. Like nothing I had ever experienced. Never taking this antibiotic ever again."

"I use the Cephalexin to treat the absessed teeth i have. I have used it before with UTI's. I am allergice to PCN and my doctor perscribed the Cephalexin said that people that is allergic to the PCN can take the Cephalexin and it does the same job as PCN does."
