I have been prescribed this medication many times for tooth absesses or infections and it is the only one that cures my problem. Regular penicillin drugs never helped me at all. This also unlike the penicillin drugs will not give you a yeast infection and I never had any side effects.

I have been on generic Keflex for 3yrs+ due to major knee replacement infections (5 surgeries). Must take for the rest of my life or lose my leg. It has worked. BUT I have felt progressively worse, pain, fatigue, high blood pressure problems, hardening of the arteries. I have just learned that Keflex interfers with a body making vitamin K2 which directly works to protect from the above problems. My doctor should have had me taking Vitamin K2 supplements. There are many studies worldwide about what low K2 will do to health. PLEASE research K2 if you have to take this antibiotic, you need BOTH prescription medication and natural suppliments for the side effects of the medications. Keflex also makes your urine smell bad, stomach/gut issues you must learn to live with.Read More Read Less

I have a UTI. I’m on keflex 500 mg twice a day. This is my second day and already the burning has stopped. I have had no side effects. Take this with food. I had bad anxiety with ciproflaxin. I will only use this Keflex now for in the future. I’m 48 premenopausal and this is my first UTI ever. I’ll probably get my hormones checked since premenopausal low estrogen can cause these. Try this Keflex though. It was easy to use and comes in liquid.

was prescribed keflex 4 times daily for cellulitis caused by a tattoo infection. the inflammation went away within two days or so, and i can see progress that the cellulitis is subsiding. i do, however, have most of the side effects that come with keflex. nausea, slight tachycardia, and headaches started on day one, and diarrhea followed on day five. i have also been VERY tired and sleeping most of the week, but that may be because of the high dose. side effects aside, i’m satisfied with this antibiotic!!

Prescribed for UTI by a Care Now doctor. Caused C. Diff, and had to go on more antibiotics to treat that. A little while thereafter, I started experiencing systems that ultimately were diagnosed as hypothyroidism. I had zero problems until I took Keflex. My PCP suspects that the resulting difficulties from Keflex knocked my thyroid offline. Now I'll have to take thyroid meds for the rest of my life, still working off the weight gain, etc. Read the side effects: women ages 40+ should never be prescribed this!!!Read More Read Less

In Sept., I have 500 mg 3 times a day for 7 days to treat UTI. After talking the 2nd pill on the 1st day, I started feeling back pain. On the 3rd day and after, having abdominal pain ( intestinal pain). No diarrhea but just pain. I stopped the medicine on the 5th day but still have abdominal pain. On Oct 5th, did ultrasound and was normal. On Nov 5th, did CT scan because of the pain. It said my stomach wall is thickened and suspected a gastric. On Dec. 17th, did a endoscopy test and said inflammation in the lining. I donâ??t have any stomach problems before taking the antibiotic. I suspect it cause the stomach problems even I finished it 3 months ago? Now I need to take medicine for my stomach. This antibiotics was strong to kill UTI but bad for intestines and digestive system. Donâ??t know when my stomachache will be recovered. Donâ??t take Keflex!Read More Read Less

Switch after taking Macrobid (TERRIBLE side effects); Keflex was easy to take and worked quickly.

I was prescribed keflex for the second time for a staph infection in my eye. The first time was for a bacterial infection in my lungs and I had a horrible reaction to it at that time with severe stomach distress and diarrhea. This time, within an hour I had severe projectile vomiting and diarrhea which lasted non-stop for 12 hours. I finally called an ambulance and got admitted to the emergency room where I stayed for a day. this was the worst experience I have ever had and we'll put this on my list of do not take drugs. Weeks later I am still trying to get my intestinal tract back on gear.this was scary and painful.Read More Read Less

Had severe joint pain with this medication. After taking the very first pill. It started in my left hand joints then spread to my right elbow. By the end of the day my toes and feet and my knees were also in extreme pain. It was almost unbearable. Stopped taking immediately.

I went to the ER for acute cystitis with hematuria, and were given two 500mg to take onsite. Within twenty minutes, my face extremities was feeling slightly numb, like I hit the funny bone but much, much milder, this feeling only lasted for maybe half a hr. Few hours later, my discomfort lessened when I went to pee. By the morning, I had no discomfort whatsoever. I have been taking this with food, not sure if that helps, but I haven't experienced any side effect from keflex. 500mg for 5 days, 3x a day. I take it every 8 hours on the dot as t says it's best to space the timing out evenly. Initially, I had inquired about a different antibiotic, and the doctor told me that they prescribe one that is effective based on which one has drug resistance in the community. The one I inquired about, was shown to be drug resistant in my community. After I finish my prescription, I'm going to eat a lot of yogurt to hopefully help build back up the gut microbiome.Read More Read Less

Used Keflex to get rid of uti. Took 2x a day for 7 days. I noticed the pill has some type of odor, which made it harder to swallow. UTI went away just fine. The bad part is that I'm experiencing vaginal dryness and a possible yeast infection.

Although this drug was effective in treating a skin infection related to an eczema outbreak it has really messed me up. My stomach always seems to feel nauseous, irritability still exists on and off for no reason, I have had a headache on a daily basis, never had diarrhea with this but have not had normal or regular BM's since I started taking the medication, also It seems I have become allergic or sensitive to new things since finishing the medication. It has been 3 weeks since I have completed the antibiotic and the doctor told be the side effects could last up to a year and I should pay close attention to the stomach issues. I didn't want to take an antibiotic at all in the first place as I am very allergic to several. This really sucks!!! Been keeping with a clean diet and drinking plenty of water to help get this med out of my system. At this point I don't know what else to do but bear with it until it is totally out of my system. I can say though this is another one added to the list of antibiotics I will not take ever again. Read More Read Less

I had been overprescribed antiobiotics as a child, so was resistant to take any as an adult. My Doc suggested I try to take these along with a good probiotic. I noticed a profound change in the smell and color of my urine the following day of taking it. Some mild cramping on day four, and slight loose stools (upped the probiotic), but otherwise, well tolerated. Will be getting my urine evaluated soon to determine the wbc count (here's hoping).

I had a thread pop out almost 3 months after open heart surgery in my stomach area just below the staple scars. It got infected, so I was put on Keflex. I'm trying to drink Kefer to avoid a yeast infection, which can happen with any antibiotic. My worse complaints so far are extreme tiredness and with some dizziness. It almost feels like a chest cold in its beginnings, too. Plus, I seem to have more aches and pains than usual. So far, I haven't had it cause any horrid/long term side effects like an antibiotic called Macrobid caused me in 2013.Read More Read Less

Took Keflex for bacterial infection of leg after broken patella and road rash. Injury caused great pain in calf and knee and infection caused leg to swell and throb. Swelling subsided but nerve pain in calf and foot is bad. Side effects included tiredness, dizziness, lack of appetite, minor itching. Dark stools appeared after day 7 of treatment; had been pale earlier in treatment. Scanned for DVT in calf, was negative. Have mild cirrhosis; no alcohol use for two years. Will monitor side effects including stools after completion of treatment. Musccle/joint pain also a side effect.Read More Read Less
