For a mild cold with fever, plain paracetamol is the safest option for a 5-year-old child, and combination medicines, such as Meftagesic-P syrup (Mefenamic acid and Paracetamol), are usually not needed. Solvin Cold Syrup (Paracetamol, Phenylephrine, and Chlorpheniramine) should be used in children only if prescribed by a doctor. Please consult your doctor, who will decide the correct dose and duration based on your child?s condition.
