I also face critical situation low blood pressure,Headache and diarrhea. So i decided to quit and decide not to use like that medicine again.

Mon, 07 Nov 2011

One more pill to go before I finish my dose of Cephalexin for Cellulitis. First of all, the symptom worsened within the first 24 hours - both the doctors failed to tell me that. It did eventually work and about 48 hours later, the swelling and redness from Cellulitis started to decrease. The side effects were not severe, but, at worst, I experienced nausea, stomach ache, diarrhea, and depression (followed by the most whacked out dreams). This is not quite the drug from hell but I am very much ready to finish my dose.

Fri, 16 Mar 2012

After taking Cephalexin I experienced nausea, vomiting and headaches which 800mg of ibuprofen couldn't control. The sweating (head to toe) was profuse and disconcerting.

Sat, 31 Mar 2012

After a double treatment of Cephalexin 500mg 4 times a day, I am still experiencing intestinal discomfort and loose stools. I also get a lot of gas, bloating and it makes it hard to go anywhere because of the sudden diahrrea that goes with it. I will NEVER take this drug again!

Sat, 18 Jun 2011

I am currently on Cephalexin for a kidney infection. I have so far suffered from joint pain, headaches, unusual vaginal pain and itching, dizziness and discovered a sore throat this morning. I plan to finish my dose but it seems like I'm suffering worse now than with my kidney infection.
