"I took cephalexin 500mg for like a week and stopped it as I didn't know I was supposed to finish all of my medicine. It had me very constipated and now I have got oral thrush that will not go away. I've tried everything. I was fine before I took the medication now I have got more problems than I started with."

"I have 2 teeth that are infected and I have been taking Cephalexin 500 mg for 2 1/2 days and I'm still in pain. Why does this medication take so long to start helping? I understand it takes time but this is too long."

"My large toe on my right foot just started hurting. Throbbing pain. Then turned red and started swelling. Said it was infected and prescribed Reflex 500mg plus Bactrim. I was afraid to take both at once but figured I had no choice. 3 days have passed & feeling fine. The pain is gone from my foot but it still looks disgusting. Have a week left of both medications to go. Can't say how well they work yet since it I haven't finished the prescribed dosage. I do eat with each pill & drink plenty of water. Mostly yogurt. I have taken Bactrim and Keflex before but never together. Still a bit nervous on both!"

Keflex (cephalexin) "first my dentist prescribed amoxicillin for my tooth abscess, but when I went in for the extraction, I still had it, so he prescribed this. I lost a days worth, they fell out of my pocket. But I took the rest, and I still feel it slightly. It had no side effects for me."

"I was prescribed this at 500mg per pill with Amoxicillin 875/125 Clav to treat a cat bite :( I was afraid of taking this with amox due to a terrible yeast infection back in 2019. However, to my surprise, no side effects and it took about 3 days for the swelling to go down and my finger back to normal by day 5. I will say, as a woman, be cautious when taking this. PLEASE ask your doctor to prescribe you a 150-200 mg yeast infection pill and/or BV medication. JUST IN CASE. I've read some reviews where some women have terrible itching and swelling and their OB does nothing, not even take a culture swab to check for BV or yeast."

"I was prescribed 250mg 4x per day for 10 days for a re-occurring what I thought was a yeast infection. But I haven’t read any other reviews where this had been prescribed for yeast infections. But then realised it was an antibiotic for bacterial infections so now realise they are treating me for a bacterial infection, which is apparently just as common as yeast infections and aren't sexually transmitted either "

"16 year old son was prescribed 1000mg twice a day for sinus infection. He's been sick 4 weeks and they thought it was mono, he's already so tired all he wants to do it sleep. Plus cough and congestion. Mono blood test results came back negative so they prescribed him this super heavy dose of cephalexin for 10 days to treat a "possible" sinus infection. I don't even know if this is good or bad for my son to take so I'm reading reviews. I have not seen one review where they were prescribed 1000mg twice a day. So I'm going to give my son 500mg twice a day and see if it helps. Along with a probiotic as he has always had stomach intestinal issues. Haven't given him any yet but will keep y'all posted. Thank you all for sharing your experiences!"

"Infection in sutured wounds. A week after surgery, I had a large skin cancer removed from my neck and stitched up. It wasn't healing well and was very painful and oozing pus. I was prescribed 4 tablets of 500mg each, to be taken daily for 5 days. Within 24 hours, there was an immediate reduction in swelling and redness, and no more pus or pain. The wound is now sealing up. I haven't experienced any side effects. The capsules have a strong smell, but it is only noticeable for the few seconds it takes to put them in my mouth."

"I started taking Cephalexin 500MG on 12/23/20 not even 5 days in and I'm having kidney pain. I take 1 capsules every 6 hrs for a spider bite. Everyone here taking this for more serious reasons than why I am taking it. And other people are taking 2 a day whereas I'm taking 4 a day - I don't think that's right the swelling went down but my kidneys are in pain"

"Allegeric to penicillin, so I get Cephalexin for all my infections. Works like a dream for me, almost always clears up what I've got in a single course, I don't get side effects. I only have one question: Why does it smell so bad? You pop open the blister and the stench is is almost award worthy. You've gotta eat something after or you'll burp and the smell will repeat on you."

"This was prescribed for a bacterial infection with an UTI. Everything was going well until the early morning of the 3rd day. Waking up at 2am feeling nauseous and I was about to poo my pants at the same time. From 2am-6am my body was emptying itself out. I was finally able to contact my doctor and let them know I wouldn't be continuing this prescription. I don't want to go thru this again."

"I started taking Cephalexin to prevent any bacterial infection before it got to any parts of my body. 500mg 4xday, 10 days. The underside of my right breast split and it was a mean-looking gash. Have no idea why it happened as I've never had any issues at all wearing my bras. And no. No underwires and have had them for years, again, without any issues. :) Doc took a culture and viola! I'm on pills that come out of a bottle that smells like someone trapped a fart in it. I ended up with diarrhea, at least 3 times a day and today, I am trying out a pro-biotic to see if that will help in any way. Good luck to the newly prescribed. Different for everyone. :)"

"Had a UTI but this time with a super high temperature of 104. Sent for blood test and urine test. GP decided to give me this. This is my third day and it’s a no from me. I’ve had a bad taste in my mouth for a few days, and realised just today it’s the taste of the smell of these pills. They also started to make me vomit 1-1/2 hours after taking them. I’ve called my GP and she has issued another type."

"Took this for a bad infection of a tooth, that had gone into soft tissue. Within 2 hours of the first does I felt like I was dying in pain from the worst headache of my life... That says a lot for me because I suffer from migraines since the age of 12. I'm 29 and not the healthiest, so I don't know if that plays a part in how my body handles it. I am going to finish the antibiotic because I've heard it works amazingly. Hope this helps. Dosage 500mg/4x a day for 10days"

"Second time I have taken this. First time was 4 years ago for cellulitis, 500 mg 4 times a day for 10 days and it worked but I was in bed most of the time post surgery. This week, I was on it for a possible bacterial infection of neck up. 500 mg 3 x a day for 5 days. Very tired entire time, legs hurt to where it was hard to walk sometimes, my neuropathy got bad in feet for one morning only, I had a little numbness near mouth for a short time twice, had some whopper headaches, I dreamed heavily which I don’t do. My back molar is bothering me and I called my dentist and they said this should clear that too. It has not. Despite these side effects, I would take it again. So despite my side effects I would take it again. Calling dentist Monday!"

"I was prescribed this for cellulitis on my leg for 5 days, 4 times a day after 2 days in the hospital on IV meds. It is doing the job, but my side effects aren't any better than the problem it's supposed to fix! It started with the skin in my buttock crack peeling, and it causes diarrhea, so the more I wipe, the more skin comes off and the more it gets irritated. It's so bad it's bleeding. Now that I'm done with the pills, my vagina is swollen, and when I wipe, the skin is also peeling there, chunks of skin on the toilet paper. I don't know how long this will last. I had yogurt every day and have started to use aloe wet wipes, but it's not any better. I will probably end up back in the hospital for this now!"

"So I went to the ER because I had horrible bladder spasms, which I’ve never had. I also have interstitial cystitis. They sent a culture in, and waiting for that I am taking cephalexin. I took this yesterday and today, 4 a day, and my urgency is so bad after I pee. I don't know how long this takes to work. I called the ER to see what bacteria I had and to see if I’m on the right meds, but they are waiting on the sensitivity part to come back. These spasms and urgency are awful. :("

"I had a UTI that was treated with a different antibiotic (Macrobid: nitrofurantoin). That antibiotic caused a host of severe issues, including vision problems and a horribly infected throat(!). I was taken off it and put on cephalexin. It took one dose, and I knew it would work on the UTI and the throat infection. The side effects were mild (slight bad taste in the mouth, loss of appetite) but nothing out of the ordinary. I also always take a probiotic each day (3-4 hours after taking the antibiotic) to avoid yeast and gastro issues."

"I'm sensitive to nitro and trimethoprim (and most other antibiotics!) so I'm given Keflex for recurring UTIs over the years. No side effects during the course, however, I have found I've had to request the course be extended by another couple of days to fully clear the infection. Whether that's just how my body reacts to it, I don't know, but it does work just fine in the end without any ill effects! I'd definitely recommend."
