 3  Post surgery to prevent infection ringing in ears/head, weakness in my arms and legs, sadness, loss of energy, and increased hunger. I was prescribed this after a surgery I had, I did not get an infection, so it did its job. Side effects are scary. I thought I was having a serious medical episode due to the weakness but my family thinks it was an anxiety attack (never had one before). It passed but still monitoring it...Finished my last pill of the 7 day treatment last night. F 27 7 days

It is 6.02am and I have yet to sleep as I have spent the whole night burping with palpitations and extreme, extreme anxiety! Awful F 29 2 days

I have constant sense of doom, panic attacks, anxiety, depression, intrusive thoughts, pain/numbness in my pinky and ring finger, back pain, cramping and bladder/urethra pain ( I thought it didn't get rid of my uti the pain is so bad but I went to urgent care and they said my infection was gone), I can't concentrate or function correctly. I almost thought about admitting myself into the hospital. I am so scared I will never feel normal again. DO NOT TAKE! F 28 7 days

 1  UTI Awful awful awful. It hits you out of nowhere with this punch to your chest, headaches, heart palpitations, dizziness, nausea and extreme fatigue. It made me feel beyond depressed and i already have generalized anxiety disorder. I have taken many antibiotics before but i have NEVER experienced one that plays a part in altering my mentality as much as this one does. It made me feel irrational and impulsive in addition to being so nauseas i couldnt move without feeling like I'd blow chunks everywhere and being so hungry at the same time is absolutely miserable. I wouldn't recommend it to anyone. Get an alternative. Sucks. Dont do it. F 28 7 days

This is my first and last time taking this medication.. I never experienced this kind of side effects..

 1  Infection of nose piercing Took my first dose of Keflex at 6:45 PM, by 8 PM it felt as if I had the worst flu of my life. I had the worst body aches, even my toes and finger tips were aching. The glands in my neck were uncomfortably swollen and It was painful to swallow. I had a horrible night of sleep because the body aches were so severe. I have 5 children and was unable to care for them as I had no energy and was in constant discomfort. I also felt as if my brain was cloudy, could not think straight. Just wanted to lie in bed all day. I would not recommend this drug to anyone. The side effects are horrible. F 34 10 days

 3  UTI I am treating UTI and kidney pain. I am 4 days in and the last 2 nights and this afternoon I experienced a weird type of shaking in my upper body (Not visible but I can feel it inside) and an increased heart rate. I also got a panic attack last night and couldn't sleep anymore from the moment it started. That happened after 6 hours of taking it and lasts at least 2-3 hours. Helped with the UTI so far but the side effects are no fun. Anxiety should be listed as common side effect. F 33 7 days

 1  Urinary tract infection Extreme pain in left deltoid, could not move shoulder or whole arm. Sharp pains in right side of abdomen. Some nausea. Dry mouth and extremely thirsty. side effects for me, not worth it. However I did feel as though the medicine was working to clear up sinus infection and urinate tract infection. There has got to be something else that has less severe, and very painful, life changing side effects that I experienced!! F 50 4 days
