Cephalexin Nausea Causes and Reviews


Nausea is an uneasy or unsettled feeling in the stomach together with an urge to vomit. Nausea and vomiting, or throwing up, are not diseases. They can be symptoms of many different conditions. These include morning sickness during pregnancy, infections, migraine headaches, motion sickness, food poisoning, cancer chemotherapy or other medicines.

For vomiting in children and adults, avoid solid foods until vomiting has stopped for at least six hours. Then work back to a normal diet. Drink small amounts of clear liquids to avoid dehydration.

Nausea and vomiting are common. Usually, they are not serious. You should see a doctor immediately if you suspect poisoning or if you have

  • Vomited for longer than 24 hours
  • Blood in the vomit
  • Severe abdominal pain
  • Headache and stiff neck
  • Signs of dehydration, such as dry mouth, infrequent urination or dark urine

Cephalexin Nausea Reviews

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.

Tue, 22 Nov 2011
I have been tired and Nauseaus since I started taking Cephalexin. My doctor does not seemed concerned. I have taken 6 different antibiotics for a prostate and bladden infection and nothing has helped. I am taking multax which limits the antibiotics I can take. I can't get my urologist and cardiologist to communicate and come up with a solution. Any advice. I plan to get another urologist who might put more effort into my cure.
