I was just prescribed 500 mg of cephalexin, as a precaution. Since I am having a surgery soon. It seems like I have to pee literally every 5 seconds. Is this a common side affect, or does it mean I'm allergic? I started taking it yesterday after noon, and am supposed to take it 3 times a day. I have taken 4 so far.
Increased urination is not a known side effect or allergic reaction of cephalexin. Hope it has resolved by now. If it hasn't then I would recommend that you see your doctor ... to check that you don't have a urinary tract infection.
I started taking Cephalexin due to a UTI and I have a suprapubic catheter. Ever since I started taking it I am gushing out around the catheter excessively. I feel like a kid wetting the bed again.
I have also been prescribed this medicine for a sinus infection. I noticed this right away. I am peeing all the time or feel like I have a UTI and will just pee a drop or 2. It happens right after I take the medicine and then goes away until the next dose. Good to know I am not crazy.
Oh my god. It was prescribed to my three year old. She’s been crying each night. Score bed begging me to find diapers and to let her go pee on a potty (where she will sit endlessly). I went to a doctor today with this issue and they had no clue what’s up. This medication is ridiculous- my little one is devastated. I have been crying each night trying to figure out what it is. Wonder who I should contact so this issue can be added as a side effect.
I was prescribed this 4 days ago for a case of strep throat , I am also having the same side effect . I normally go about 2 or 3 times a day , now I'm going about 2 or 3 times every hr .cant wait to be off this
I have been prescribed 250mg at bedtime for unexplained recurrent UTI in pregnancy as a daily prophylaxis until I give
birth. YES this med does cause frequent urination and all of your answers have validated the effect I am feeling as well- so thank you for posting. Yes I am
battling UTI which does cause frequent urination but I have noticed that within 10 minutes or so of taking this, I am having to go a lot more within certain time frames, than I do in the day when I am not on it- and drinking more water. Like one poster mentioned, several times per hour, and can last 5-6 hours so imagine needing to sleep but waking up
constantly to urinate. Very inconvenient and uncomfortable. Good luck to everyone.
I was prescribed cephalexin at 500 mg. 3 times daily for a UTI. By the 2nd night, I was wetting the bed. I kid you not, I have never had to pee so much with a UTI in my life. I thought maybe I had something bad wrong and even called an online dr. She told me to go to my regular general practitioner... I'm reading about all the other people that have had the same side affects and now my anxieties are gone. The only thing is now I need diapers for the rest of my treatment. This is absolutely crazy! Thanks to everyone that has answered this question. Daytime is best because i know how long i can hold off..but night time waking and needing to go in a split second... no way.
This is definitely a side effect. It was making me pee so much and actually making my urethra hurt, I went back to the doctor to ask if I could stop taking it because the peeing was driving me crazy. I was also experiencing stinging pain with the peeing. I've been off it for 24 hours now and am still experiencing this horrible side effect.
