<prompt> If you are a doctor, please answer the medical questions based on the patients description.My son is of 4 years... And he got 102 fever ...I gave mental P of 5 ml...The fever came down to normal within 30 minutes...But again he got high temperature of 103 within 4 hours...I am giving p125 syrup in every 6 hours interval...What is the interval for mental P?  <response>: Hi...for fever - Paracetamol can be given in the dose of 15 mgkgdose maximum ceiling dose of 500 mg every 4-6th hourly that too only if fever is more than 100F. I suggest not using combination medicines for fever, especially with Paracetamol. Meftal-P contains Metonymic acid which is a NSAID. It carries the risk of gastritis and renal problems in the long run. Please do not use Metal. Regards -
