 1  Post-surgery Deep fatigue, lasting headache, nausea, vomiting, no appetite, 103 fever, aching joints, severe dizziness, general sense of dread. Two full days after I stopped taking it I am still very sick. KNOW THIS: you CAN stop taking an antibiotic in mid-course. The alleged damage related to doing so is overstated. If my input stops a single person from taking this accursed medication it was worth the time to offer a review. I have taken numerous antibiotics but never one that produced debilitating side effects like KEFLEX. Avoid this drug and its criminal impact -- demand an alternative! I would not be surprised if this drug has killed people, especially those already in a compromised state. Thanks to this site's owners for providing an outlet to those of us who have suffered due to a dangerous drug. M 51 2 days

 1  To prevent infection from a cut My daughter received a deep laceration on her leg and was prescribed Cephalexin generic for Keflex. On the third day my daughter started experiencing horrible headaches and a severe stomach ache. By the 5th day taking this drug she was miserable throwing up with a migraine. This is a horrible dangerous drug. I regret ever giving this to my daughter. She suffered for no reason!! F 10 5 days

 1  UTI Bad headache, ringing in ears, anxiety, depression (I've NEVER had that before!) pain in lower legs - shins, swollen ankles, high b.p., insomnia, weke up at 4 a.m. no matter what time I go to sleep. Lethargic, weak, tired, indigestion. On day 7 it feels like my UTI is coming back. Ribs are sore. Increased appetite (could be because I'm too exhausted to do anything). I HATE THESE PILLS!!!

 4  prevent infection had lip biopsy Day 6 into it. Prescribed a total of 2,000mg a daily to prevent infection after a salivary gland/lip biopsy. Two 250mg capsules 4 times a day. No gastro side effects, but within an hour of taking each dose I am peeing like crazy, volume and urgency. I have interstitial cystitis as well, so this is really making the urination frequency off the charts. F 51 7 days

 1  UTI Extreme GI distress I must have had an allergic reaction or oversensitivity to this drug. I had taken in the past with no major issues. Was given as treatment for UTI. Took 1st pill and felt fine, for about 2 hours.. then I felt upper abdominal/reflux-like pain that gradually worsened until I began vomiting almost uncontrollably for about 3 hours.. then, it was weird, I could almost feel the pill moving down my GI tract! I then had severe cramping and shooting pains, along with the accompanying diarrhea. In total, the reaction lasted 6 hours. Being a total dope, I thought this was a fluke.. and the next day I took another pill. Well.. the exact same thing happened. My husband wanted to take me to the ER, as it was so severe, but I rode out the 6 hours again, then all was over. I rated it low because of my personal reaction, which does not seem to be norm, but just wanted to report in case someone else experiences the same thing. F 59 1 days

 1  UTI Extreme fatigue! I was taking 500 mg 4x's a day. Had to stop taking it. Everything I ate which wasn't much had me running to the bathroom. Not good for someone with a history of colitis. I had a lot of anxiety and depression. My heart rate went to the moon. I've never taken this med before and I will never take again. F 65 4 days

 1  UTI I was supposed to take it a week, but could not manage. Horrible G.I. effects, diarrhea, stomach pain, bloating, mucous. Insomnia, brain fog, heart palpitations, feelings of despair and anxiety, joint pain, back pain, generally wanting to give up on everything. Headache. Body chills and freezing hands. A wretched experience all in all. People over 50 generally don't do well on this drug. Two things can help if you are stuck taking this: 1. Magnesium supplement for the heart palpitations, the drug depletes MG.; and 2. a specific probiotic which has Saccharomyces Boulardii in it. Most drug stores and groceries have it mixed in with the usual probiotics. Read the labels and find this--it REALLY helps with Diarrhea and G.I. pain. I will never again take any antibiotic without supplementing with this. F 60 3 days

 2  UTI, Diverticulitis Prescribed this because original scrip of Cipro and Flagyl gave me 'flying out if my skin' anxiety attacks. First 2 doses were fine, but after 3rd dose noticed headache starting to build. Also felt utterly exhausted and wanted to crawl back in bed. Anxiety attack hit 2hrs after 4th dose. Not as bad as with other meds, but pretty unpleasant. Read that it may stop after I get used to the drug. Just want to get thru the next 5 days so I can get better and never have to take this again.

 1  Infection Anxiety, depression, suicidal thoughts, felt helpless, confusion, sadness etc. My 12 year old daughter was prescribed Keflex for an infection. Within a day of taking this her anxiety had increased drastically. After day 2, she had a major panic attack and confessed she was having suicidal thoughts. By nature, she is an anxious person, BUT she's NEVER had a panic attack and certainly had never had such terrible thoughts. She was scared! This drug is horrible. F 12 14 days

 4  Kidney infection It's the only antibiotic so far that's got rid of my recurring kidney infections although it caused almost-unbearable pain in my legs, muscles and joints. Pain is so bad I can't walk for the first few days of the course. Side effects worth it as it's the only one that works for me F 18 7 days
