Parents should pay particular attention to the product’s age restrictions and directions.

Children are more vulnerable to certain medication-related problems, and camphor can be dangerous when swallowed.

Don’t apply the product to a child’s skin simply because an adult in the household uses it.

Read the label carefully and use only as directed for the appropriate age group.

10. Don’t Use It on Broken Skin

VapoRub should generally be used on intact skin.

Avoid applying it to:

Open cuts
Fresh wounds
Raw skin
Significant burns
Severely irritated skin
Areas with active skin infection

The aromatic ingredients can cause additional irritation.

If the skin is already damaged, choose an appropriate treatment for the actual problem rather than applying a strong-smelling topical ointment simply because it is available at home.

11. Avoid the Eyes

The eyes are particularly sensitive to menthol, camphor, and other aromatic ingredients.

Don’t apply VapoRub near the eyes or allow it to get into them.

If accidental contact occurs, rinse the eyes thoroughly with clean water and seek medical advice if irritation persists or is severe.

Wash your hands after applying the product.

12. Don’t Heat VapoRub

Another important point is to avoid heating the ointment or adding it to very hot water in an attempt to create stronger vapors.

People sometimes put VapoRub into hot water and inhale the resulting steam.

This can create risks that aren’t present when the product is used according to its directions.

Hot water itself can cause serious burns, particularly in children.

The safest approach is to use the product exactly as labeled rather than creating homemade steam treatments.

13. Don’t Combine It With Other Strong Topical Products

Using several topical products simultaneously can increase skin irritation.

For example, avoid applying multiple strongly scented or irritating products to the same area without knowing whether they are compatible.

If you are already using a medicated cream, ointment, or patch, ask a pharmacist or healthcare professional whether combining it with another topical product is appropriate.

14. The Cooling Sensation Can Be Misleading

One reason VapoRub feels powerful is its distinctive cooling sensation.

Menthol activates sensory receptors associated with cold.

This can make an area feel cooler even when the actual temperature of the skin hasn’t changed dramatically.

That sensation can be pleasant when you’re congested or experiencing minor muscle discomfort.

But the sensation itself doesn’t prove that the underlying condition is being cured.

A cooling feeling should not be confused with treatment of the cause.

15. VapoRub Doesn’t Cure a Common Cold

This is another important distinction.

The common cold is usually caused by viruses.

VapoRub doesn’t eliminate those viruses.

Its role is symptom relief.

Rest, adequate fluids, comfortable room conditions, and appropriate symptom management are generally more important than trying to find a single product that will make the illness disappear immediately.
