What Causes Diarrhea Followed By Itchy Rash?

Posted on Mon, 7 Apr 2014

Question: I have had diarrhea all day and upset stomach. I thought I must have eaten something bad yesterday. I still have diarrhea but now This evening I started itching like crazy and now have a rash on neck, chest, under arms, waist band, under breasts, hands and tightness in chest that comes and goes?

Brief Answer: Could be food allergy Detailed Answer: Hi Thanks for writing to healthcare magic. Your description of diarrhea followed by itchy rash corresponds to symptoms of food allergy or food poisoning. I urge you to drink plenty of electrolyte solutions like darolyte to keep yourself well hydrated. You can also take antihistamines available over the counter such as benadryl to reduce itching and rashes. Since the complaints appear to be severe, it would be worthwhile to visit the nearest ER for further evaluation and management. Hope this helps. Regards Dr Arun

Brief Answer: Try ondansetron. Detailed Answer: Greek yoghurt could have caused your problems . Dairy products get contaminated easily. Avoid taking it any further. Try ondansetron tablets 8 mg before food thrice daily which is usually prescribed for vomiting. Regards

Does that need a prescription or over thecounter

Answered by Dr. Arun (11 minutes later)

Brief Answer: It is not over the counter at most places... Detailed Answer: Unfortunately this is not available over the counter in most countries. You can check with your pharmacist. You may also try other over the counter antiemetic drugs if you are unable to find ondansetron. Regards
