<s>[INST] My son had a fever of 103.2 about an hour ago. I gave him liquid Tylenol and just took his temp...102.7. It is still high but other than body aches, slight headache, and little sore throat he seems okay...just really tired. Should I do anything else for him or just let him sleep [/INST] Welcome to the ChatDoctorI completely understand your concerns but don't worry. Occasional fevers with lethargy and body aches can be due to viral infections. They usually improve in 3-4 days. If your children fever spikes are not responding well to Tylenol doses even after 1-2 hours, you should take the following measures:1. Check the dose. Ideally it should be given at 15 mg/kg/dose. If still the fever doesn't respond, you may repeat the same dose after 6-8 hours. 2. Spy. Metal P can be given for fever spikes not responding to Tylenol.3. Cold sponging will be helpful in relief of fever.4. You can start him on Spy Ben Chat Doctor. Hopefully this will help him. For further questions, you may contact me. Take care </s>
