"I am recovering from bilateral uretal stents for 3wks and having 3 kidney stones total removed with basket. Well, this was the antibiotic of choice because I could not take Bactrim, after two doses I'm really sick. So, my Urologist prescribed cephalexin, 3x a day 500mg. This feeling did not start until I was done. After eating, especially diary, the bg's would settle in and after that, all my food is dumped out of me into the toilet with little warning and No time waste getting there. No one told me I needed a probiotic, thanks to my friend nurse, a week after finishing this medication. After this explosive bm, it takes a day or so to get back to normal. So, with that being said, how do you keep this reaction from ever happening?"

"My heart raced, I was agitated and shaking, my mouth and lips felt like sunburned inside my mouth and outside. We need an investigation where this medicine is made? DO NOT TAKE IT. Prescribed for a UTI and when I stopped taking it I had to take benadryl. THROW IT AWAY! I had taken Keflex and did not have the severe reaction. There are blisters on the top of the mouth today. I started the med. Sat. and this is only Tues."

"My gyn placed me on Keflex 3x per day at 500 mg each for 7 days, for removal of a polyp located while in for an annual gyn visit. This is the 2nd time I've had these odd polyps, the first time in 2017. My doctor after the 2017 removal, dr was proactive this time ensuring no bacteria stirred up, due to my reaction to the bacteria infection caused from 2017 polyp removal. I am very pleased, and thankful for his proactive approach, bc I felt like I was going to die in 2017 bc of the infection it caused. Not the doctors fault at all, the polyp was infected. Keflex has prevented me from any further complications at this time, and I'm grateful."

"I have been prescribed Cephalexin twice so far; each time for foot surgery to prevent infection. The first time, I had no problems. This time, however, I am finding that I am extremely gassy, although I haven't seen this as a side effect anywhere. The only other medication I am on at the moment is 800 mg Ibuprofen but I have only taken one of those so far. I also find myself waking up to a bit of a sore throat and tonight I had a coughing fit and feeling like I was going to throw up. I'm not sure if this is the cause of the Cephalexin, but I just thought I'd share."

"I was prescribed 500mg @ 3x daily for a cyst that I didn't have (the "Doctor" gave me a 5-second exam). Three days later I'm out of bed at 3:00 a.m. with my neuropathy more painful that ever. Since then I've been experiencing "spells" or "episodes" in which I experience severe disorientation, painful vertigo, respiratory and circulatory problems. It also rendered me impotent (all of which has been going on since August 2015). I also have little control of urinating as I cannot tell when, nor can I feel the urine leaving. I can't even stop it "midstream". My gut is finally returning to "normal", yet, because of what the Cephelaxin did, I still need to be near facilities when I have to go."

"Was prescribed Cephalexin for an infection after a previous antibiotic didn’t work. The infection almost completely cleared up within 24 hours. Worked very well & would definitely recommend. Side effects: Sore stomach & dry/bloodshot eyes. Both went away after I finished the course of antibiotics."

"I am currently on cephalexin 500mg × 4 times a day for my Strep throat and UTI. It has completely taken my appetite so I now have to force myself to eat. My stomach hurts so bad, severe headaches, diarrhea, and hot and cold flashes and all I want to do is sleep all day. I'm only on day four and have 3 more to go if I can make it"

"I was prescribed a week's worth of cephalex. Four 500 mg capsules a day for a possible UTI. For the first 2-3 days of taking this medication I felt like a bloated dizzy tired zombie and didn't feel an improvement. For one of those days I got horrible constipation and indigestion. I couldn't pass gas. It scared me and made me anxious. I began to question whether this med would actually work for me. I also recommend taking a probiotic with this medication since it does go hard on your digestive system in my experience. Thankfully by the middle of the 3rd day I finally felt some relief and started to feel a bit better. I had less pain. Unfortunately though the next couple of days were a rollercoster with the persistent stomach pain and constipation. After treatment urine tests came back free of infection. I still have some stomach pain, dizziness, fatigue, some constipation though hopefully it goes away soon. Will keep treating and healing my stomach with probiotics. Maybe I would try another med next time."

"I'm currently half way through my keflex treatment for a skin infection on my ankle I'm prescribed 500mg twice a day for 30 days. I wish I could be one of the few to say this has been a pleasant experience. I'm not sure if whatever this infection is is just highly resistant or was just that bad, but I'm on week 3 and have only seen mild improvement so far. Plus this stinky antibiotic is making me miserable... Nausea, diarrhea 5xs a day on average, stomach cramps, and joint aches. I've been taking probiotics the entire time I've been on keflex because I've always had issues with yeast infections even prior to this. I plan on calling the dr tomorrow to see if I have any alternatives."

"I started this (500mg 2x a day) due to strep throat and also a finger/cuticle infection. The strep throat was 85% better within 24 hours, and now on day 3 the inflammation and infection in my finger is definitely and noticeably going away. In addition, I feel great! So much energy! I’m so grateful because the strep really wiped me out before I got this medicine started. I feel so good now I wish I felt this energetic all the time! Lol I guess my body does well on antibiotics. Take good care and I hope you feel better soon too "

Keflex (cephalexin) "I some how got bit by a spider on my upper thigh area a year ago. No idea what kind of spider it was except I had a really bad reaction to it which concerned me because most times things like that don't affect me much. I ended up going to the hospital and was prescribed Keflex 500mg 4 times/day for 10 days. I noticed improvements within a few days and it cleared up beautifully. I had no side effects whatsoever. Today I had to go see a doctor again about another bite with similar reactions. He also prescribed Keflex 500 for the same dosage and time period. I'm hoping for the same results as last time, but thinking of checking into some probiotics due to the strength of the prescription."

"The drug did help with my infection in my mouth that I had gotten from a piercing, but the side effects are awful. I was told to take 4 a day for 10 days and I've had to expand the days because I cannot take 4 a day without wanting to pass out or throw up. I get so nauseous and am extremely tired from it. If you do take this pill make sure you eat A LOT."

"I had folliculitis. My Doctor prescribed to me 500 mg 4 times a day for ten days. I had to stop at day 6. I had diarrhea up to 5 times a day. Then I got a yeast infection on my penis right after I stopped taking cephalexin. Currently, I have candida overgrowth and it is not going away. I wished I never took this antibiotic... it does more harm than it does help."

"Finished a week on Keflex for a skin infection on my leg, so severe I could not put weight on my leg. Back to ER put on Clindamycin 300mg x 3 for 10 days. Come back if no improvement after 3 days. After 3 days pain has improved swelling better, must be working. Makes me tired, and a little dizzy. Take probiotics for any GI issues. Always take with food."

"Doc gave me 3x500mg per day for an infection. He wasn't sure what type of infection it could be but was sure it was either UTI or Kidney infection...believe me, I felt terrible for 3 weeks. I took my first one before I went to bed and felt great the next morning. I am 4/7 days into my course and I feel like a different person. Absolutely no side effects at all and this has restored my faith into medication."

"I was treated for number of bumps (infected) in vaginal area. I also have untreated diabetes may be why she gave me a powerful antibiotic. I'm also scared to have good bacteria taken away but the pain was unbearable; I couldn't walk or sit. After one dose before bed and I have fallen into a deep sleep after each pill...Still awake after dose 4 though. I feel so much better. I haven't had other side effects. It still burns when I pee - I pour water down there at same time, seems to work. Sounds like less side effects for UTI patients than other infections. I also boiled hot water with garlic (all natural vegan) and drank like soup before going to the dr and also placed in warm compress to treat it naturally....worked. (garlic is supposed to be a cure all for yeast infections) So now I'm just waiting to see if the bumps clear up by the end of these pills. I can walk comfortably now."

"Got diagnosed with mastitis for the first time this week from a stubborn clogged duct and prescribed 500 mcg 4 pills a day. Luckily I caught it early and it only took two pills for the mastitis symptoms to go away. After 6 pills I started to get extremely light headed, dizzy, and disoriented so much so that I couldn't drive and had to have someone babysit because I was afraid I was going to pass out or worse! My doctor cut my dose down to two pills a day so hopefully that will help the side effects. I've never experienced such horrible side effects from any medicine! I don't know what was worse the side effects from this medicine or the mastitis! I'll never take this medicine again!"

"Doctor prescribed 500 mg 4 times a day for a Septoplasty Surgery. I’m on day 6. All it has done for me is stop the bacterial infection from my sinus and make me feel extremely tired. Can’t wait to finish this medication and hope fatigue goes away."

"I am taking this cephalexin for a bacterial infection related to a wound on my leg from road rash. Second time using this in one year and both times it cleared up my infections. My first was a large wound on my elbow that would not heal after several weeks. Was finally prescribed cephalexin with a topical cream. My arm was in terrible pain from bruising and the open wound in which I could not even have the slightest pressure applied. It healed but looks like it was burned badly but I’m just happy it healed. Diarrhea both times and mild burning while urinating (I’m male if that matters). Also, my skin dried out (all over my body) both times in the middle of the summer which never happens to me."

"On keflex 500 mg for 4 days then ancef by IV for 6 days and then 1000 mg keflex for 3 days and major vertigo started. Have self removed meds as it is a weekend and no one to call. Was to be on for another week. It is for cellulitis that came back from treatment a month ago. It seems to have cured that. I have been reading stuff online about Keflex and hearing loss and ear problems eg vertigo and it is well worth doing some looking up about it Hope it resolves quickly so I can return to work on Monday."

"I took this medicine on two different occasions for an infection and on BOTH occasions it made my throat swell up, hard to swallow, extreme dry mouth to where I had to take sips of water every 10 seconds for hours on end just to keep my mouth wet! I was prescribed 500 mg 4 times a day. Didn't even get passed the 1st day. It also gave me diarrhea that smelled just like the pills do. Made me nauseas. Will never touch again."

"I have an abscess growing in my nose. Basically it is a puss fill pimple. Very disgusting to know this is inside my sensitive nose. I was prescribed 500 mg 4 times a day. Within the 4th dose I noticed the pain in my nose less and less. I am on day 4 and although I feel the occasional tenderness in my nose the meds are working. But...I feel horrible. I have constant stomach cramps, tightness where it hurts to bend over or reach for something where I use my stomach muscles. I have gas and I'm bloated. I feel dizzy to the point I occasionally lose balance. So far I haven't had diarrhea, probably because I tend to be constipated lately due to other issues. I have though used the bathroom twice a day but it is a relief to go."
