Question

My child is ten months old, has a runny nose, sore throat, and a body temperature of 38.5 degrees. How should I handle this situation? Should I administer a fever shot or give the child fever medicine? Can I give my child both Merck and pediatric paracetamol yellow phenylephrine granules at the same time? They have already received one dose of antibiotics; do I still need to take antiviral medication?
