Please do not use regular Vicks VapoRub on a child under two years old, as ingredients like camphor can be harmful to their developing airways. Instead, you can safely ease his congestion by using a cool-mist humidifier in his room and applying saline nasal drops to help clear his nose. For his fever, you may use pediatric acetaminophen or ibuprofen; please consult his pediatrician for the correct dosage based on his weight. Ensure he gets plenty of fluids and rest.

A sudden fever, severe throat tightness making it hard to swallow, and a headache suggest a throat infection, such as strep throat. While Vicks Vaporub can be soothing, it won't treat the underlying cause. It is very important that she sees a healthcare professional promptly for an evaluation, especially since swallowing liquids is difficult. To help her feel more comfortable now, she can take generic paracetamol or ibuprofen for the pain and fever. Please encourage her to take small, frequent sips of water to stay hydrated.
