<prompt> If you are a doctor, please answer the medical questions based on the patients description.My 6 yr old had 102 fever and complaining of stomach aches last night. His vomit smelled just like permanent wave solutions type of ammonia. He recently started a stimulant XR ADHD medication this week as well. Not sure if this a side effect of the meds or just a stomach virus. What would cause that particular odor?  <response>: Hi, welcome to Chat Doctor. Fever with vomiting in a 6-year-old child could be due to food poisoning or gastroenteritis. This could be due food that he ate 1 day back. This seems unlikely due to XR ADHD because if it is due to this Chat Doctor. In my opinion, you should give antibiotic like syrup of lox 5 ml50 mg three times a day for 3 days, syrup coastal 5 ml three times a day for 2 days. Review after 2 days. I hope this will help you. Take care.
