Overview

As a community pharmacist, you will be asked more about supplements can kids take for cough and cold. Many OTC cough and cold medicines commonly used by adults aren’t recommended for children under the age of 6 years old. So, you may find parents asking if any supplements can be safely used...

Most supplements are evaluated for safety and effectiveness in adults, NOT kids. But kids are still getting sick – so, what can they use?

Management approach

Worth trying

The most popular ingredient in "natural" cough and cold products for kids is HONEY. Research shows that taking 0.5-2 teaspoons of honey at bedtime can reduce coughing and improve sleep in kids 2 years and older with a cold. It’s also at least as effective as common OTC cough suppressants like dextromethorphan (Codaphen). But make sure parents understand that they should NOT give honey to infants under 12 months – doing so puts the child at risk for botulism poisoning.

  • There are also several nonpharmacologic strategies that can also benefit kids.
    • When done properly, nasal irrigation can safely improve symptoms of colds and allergies in children.
    • Using humidifiers can also help.
    • Remind parents that for many kids, drinking lots of fluids and eating soup might be all they need to get over a cold.

Consider avoiding

Elderberry is a popular ingredient commonly used for cold and flu symptoms. Taking elderberry extract might shorten the duration of cold and flu symptoms in kids over 12. But keep in mind that many products don’t contain enough elderberry extract to have the benefits seen in clinical research, and safety in children under 12 isn’t clear. Parents might also ask about camphor. It’s FDA-approved as a chest rub for cough in adults. While it’s safe and effective to use topically for cough in adults, camphor is actually POSSIBLY UNSAFE for kids. Kids are more prone to its side effects even when a small amount is absorbed through the skin.

  • Vitamin C and zinc supplements are also very common. While these supplements may shorten colds or improve coughs adults, high doses are typically used. These high doses might not be safe for children and may increase side effects. The risk probably outweighs any benefit.
  • Echinacea is also very popular in cold supplements. While it might benefit adults, it actually doesn’t seem to benefit kids. It can also cause an allergic skin rash in some children.
  • Explain to parents that despite what they might read on the internet, most supplements haven’t been adequately tested for safety in children. Most studies evaluate use in only adults.
