| 1 | Minor surgical procedure | Severe nausea, severe dizziness, severe headaches(consistently), horrible weakness, metallic taste in my mouth, decreased appetite, chills, blurry vision, irritability, confusion, increased heart rate, slight diarrhea for the first 2days, crying spells, sadness, feeling of gloom, upset stomach, warm stomach, slight vaginal itching, feeling hopeless and alone, fear. | I didn't complete the 7 days. I stopped at the end of day 6. I couldnt take it anymore. I am on the 5th day since I last took that medication and I am feeling worst with all the above symptoms. It's just not going away. I felt like taking a knife and running it through my stomach. I feel like my life is slipping away. I can't get out of bed. When I stand up, I have to lie back down. I am tired, make it go away. I am taking probiotics, prebiotics, etc etc but it's not working. I hope the bacteria in the probiotic tablets were alive and not dead. I will never ever take another antibiotic, at least not keflex or any in its class. The FDA needs to recall that drug and the smell of the tablets makes it worst. I stopped taking them and I can still smell them. My urine smells like chemicals. I HATE KEFLEX | F | 37 | 6 days 500mg 4X day | 3/31/2021 | 4 | Sinus infection/Sinusitis | Anxiety-mild to severe, depression, edginess, irritability, anger, muscle pain (lower back, legs, neck especially), fatigue, brain fog, generally feeling just unwell, diarrhea, upset stomach, bloating, crying, panic attacks, muscle aches, headache that lingers daily, muscle tension (especially neck and lower back), low appetite, nervousness, dry mouth, high blood pressure, dizziness, confusion. | Most above side effects really hit you 5-7 days in for those it doesn't nearly immediately effect. I felt fine the first 3-4 days but day 5 was terrible and horrible. I was not feeling like myself. Keflex never gave these issues to me or my family whom also takes it for sinus infections since ours are bacterial. I was feeling like I lost my mind until I began reading reviews on here. Keflex did its job but the side effects are just horrendous. Taking some probiotics with this antibiotic and especially after finishing it will help many side effects. Most are caused by the disruption of the "flora" in your gut, which is essentially where most processes happen in our bodies. I have noticed there must be a formulation change in this drug, since prior to a few months ago, I never had any bad side effects like I have. Opening the bottle, the pills just smell very chemically (they always have smelled, but more sulfur like than chemicals). A few others on here have noted they used to not be bothers by Keflex either. I've never experienced all these symptoms in one antibiotic before. If you can be prescribed a different one, I would suggest it. | M | 24 | 6 days 500MG 4X day | 3/11/2021 | 3 | UTI post op | INSOMNIA. Severe anxiety. I cannot get comfortable, I get hot flashes then get cold super fast. I feel like I am drowning like I cannot catch my breath because of mini panic attacks. The anxiety at night is the worst. | F | 23 | 10 days 500 4X day | 3/8/2021 | 1 | UTI | Fatigue, anxiety, depression, overall sick feeling! | F | 67 | 2 days 500 mg 3X day | 2/28/2021 | 2 | UTI | My mother was prescribed this for a suspected UTI. She has Parkinsons and other issues that already make sleep a challenge. She finished this medication yesterday, but her sleep has been so poor the last few nights I was searching for a reason. She cannot tell me what is wrong, but by her behavior it appears her symptoms match what is described here. She fidgets, pants and groans for hours at a time during the night. She is disoriented. She pushes the covers off, then she is cold but she won't leave them on. Last night she was covered in sweat.. She doesn't want to get up in the morning. Fatigue, muscle aches, weakness and urinary frequency were all issues prior to taking Keflex but now that she's not sleeping everything is worse. Keflex is overkill for a UTI since Amoxicillin has worked in the past. I hope these side effects wear off soon. | I recommend asking if a different antibiotic would work for anyone with a history of neurological or psych conditions. | F | 83 | 7 days 500mg 4X day | 2/11/2021 | 4 | Post op | Bloating gas Farting loads and burping | I'll persevere for the next 3 days although the smell is unbearable!!! | M | 54 | 5 days 500 3X day | 2/5/2021 | 1 | Folliculitus | DON'T EVEN RISK IT. I am LITERALLY sitting in the ER as I type this. Why am I here? OH..Hearing VOICES. Telling me Im gonna die & they need my soul! WTF!!!! Only change...Keflex. ! | DON'T Do It. | F | 49 | 6 days 4X day | 1/15/2021 | 1 | Sinus infection | SEVERE ANXIETY insomnia horrible dreams when able to sleep heart palpitations dry mouth anger aggression depression suicidal thoughts | Do not take this I was about to check myself into the psychiatric hospital. | F | 42 | 6 days 500 3X day | 1/4/2021 | 1 | UTI | The main side effects I felt while taking the meds was frequent urination, lethargy, restlessness and insomnia. It was after completing the course that the real side effects hit. I am 2 days out now and have a terrible headache since stopping. I feel completely weak like as if my legs are about to give way underneath me. Terrible anxiety.....woke up last night with the worst anxiety attack ever....legs were shaking uncontrollably for a full hour. Finally settled but had the craziest thoughts for hours before finally falling back to sleep with sheer exhaustion. Hope these side effects pass soon. Never taking this poison again. | Avoid if you're at all sensitive to medication. | M | 44 | 7 days 500 MG 2X day | 12/30/2020 | 3 | UTI | Nightmares, anxiety, restlessness, confusion, stomach pain. It's clearing up the UTI, so it definitely works but the side effects are awful. | Have been having horrible nightmares all night and am now laying here at 4 a.m. afraid to go back to sleep. | F | 51 | 3 days 500 mg 3X day | 12/15/2020 | 1 | Uti | Extreme anxiety and high BP 165/95 at times. Some palps too | Had not used in yrs. never took for 10 days. Uti much better but insomnia high anxiety and BP!!!! | M | 67 | 10 days 500 2X day | 11/20/2020 | 1 | Prevent infection | I started having anxiety, dryness in the month this drug doesn't kill me. | M | 21 | 3 days 500mg 1X day | 11/19/2020 | 1 | UTI | Back pain after the 2nd pill on the 1st day on 9/12/2020. Abdominal pain at the left side and right side on 3rd and 4th days. Loss of appetite, upset stomach. Get change to another antibiotics on the 5th day. However, painful abdomen never stopped after 2 months until now 11/08. Now also have heartburn and stomachache. Need to see Gastroenterologists. I suspect all this pain is from Keflex. It hurts the stomach and digestion system. I don't have that pain before taking keflex. | It kills UTI good but side effects more serious! | F | 49 | 7 days 500 3X day | 11/8/2020 | 2 | infection after tick bite | Joint aches, chills, chest discomfort, stomach upset, diarrhea, unquenchable thirst. | I took it for 2 days and had to stop. | F | 33 | 7 days 500 MG 3X day | 10/20/2020 | 1 | UTI | Anxiety like I've never had before. Aggressive behaviour, aches and pains all over my body. I was so concerned about my mental health. It dawned on me that it all started when I commenced cefelex. The pains in my feet were unbearable. I am a fit healthy 61 year old female. I will never take Cefelex again and warn my Dr of the dangers. Especially for someone with mental health problems. The anger issues it caused for me where frightening | F | 61 | 8 days 500mg 2X day | 10/18/2020 | 2 | Suspected UTI, endometriosis | Horrible sweats, excessive sweating, restlessness, insomnia, heightened anxiety, itchy | Had an ultrasound, suspected endometriosis with ovarian cysts present. The doctor said it appeared I was getting an UTI and that I should take the keflex for 5 days. By day 2, I started itching and sweating profusely. My abdominal pain has worsened and my anxiety is awful! I had a difficult time staying asleep and remaining comfortable. | F | 41 | 5 days 2X day | 10/15/2020 | 3 | Uti | Dry skin above the lips and on cheeks, muscle cramps ect back, lower back, legs and shoulders. Extreme anxiety and depression to the point my husband pointed it out my mood changes. Insomnia- can't sleep through out the night. Wake up every three hours. Frequent toilet runs. Low in energy. | I had uti quite frequently in my twenties and have been prescribed a lot of Keflex. After many years of not contracting the infection I forgot how terrible the side effects were, until recently had to. Back then my family and friends always told me I'm a moody unstable person. I wonder now perhaps it was the frequent use of keflex. | F | 38 | 7 days 500 3X day | 10/13/2020 | 1 | Severe Kidney infection 500mg | 1st I have ALWAYS taken ciprofloxacin for a kidney infection and felt better within 2 days... my side still hurts, I have had severe headache for 3days, my calves hurt and I still just dont feel well. I called the ER to see if they could change the prescription and was told No... after looking up the differences between cipro and keflex, cipro goes straight to the kidneys to start working on the infection.... they prescribe keflex for UTI's when there's a concern for a kidney infection... I mean to me, that's a no brainers when someone has a 104 fever with a severe kidney infection...CIPROFLOXACIN....why this DR would give me keflex something I have never taken before for an infection...I do not recommend this if you are wanting a faster recovery time | I have aches and pain all over my body, when someone touches me, it feels like a burning sensation...I haven't been able to sleep well at night... when I wake in the A.M. I have the worst headache with my eyes hurting.... I'm hoping this will fix my infection if not, I'm probably going to have to go to another doctor to get prescribed ciprofloxacin | F | 49 | 4 days 3X day | 10/11/2020 | 1 | Severe Kidney infection 500mg | 1st I have ALWAYS taken ciprofloxacin for a kidney infection and felt better within 2 days... my side still hurts, I have had severe headache for 3days, my calves hurt and I still just dont feel well.
