I know about these medicines only from movies. Where I live, it's pretty hard to get a prescription even for antibiotics. Mostly it's a mix of self-healing combined with a plant-based medicine combination. Does the kid have a fever? Over 38.5°C (101.3°F), you can give Paracetamol to your kid. Other than that, tea, honey and rest. And some honey and plant-based candies for the throat pain.
PS: But I know what speed is, so I can imagine. 😂
