The best medicine for a child’s cough depends on the child’s age, but for most kids, home remedies like honey work as well as or better than over-the-counter cough syrups. In fact, cough and cold medicines should not be given to children under 4 years old at all, and many pediatricians recommend avoiding them until age 6. Here’s what actually works, what’s safe at each age, and what to skip.
Why Most Cough Medicines Aren’t Recommended for Kids
Over-the-counter cough suppressants and expectorants have not been shown to work in children. Multiple studies comparing these products to placebo (a sugar syrup with no active ingredient) found no meaningful difference in how quickly coughs improved. On top of that, these medicines carry real risks for young children, including drowsiness, rapid heart rate, and in rare cases, serious side effects from accidental overdosing.
The American Academy of Pediatrics and the FDA are clear on the age cutoffs: no cough or cold medicines for children under 4. Between ages 4 and 6, use them only if a doctor specifically recommends it. After age 6, OTC products can be used with careful attention to dosing instructions, but they still aren’t especially effective.
Honey: The Most Effective Remedy for Ages 1 and Up
Honey is one of the few remedies with solid evidence behind it for childhood coughs. A well-known study published in the journal Pediatrics found that children who received a small dose of honey before bed had less frequent and less severe coughing overnight compared to children who received no treatment or a honey-flavored placebo. The improvement was meaningful enough that parents reported better sleep for both the child and themselves.
For children ages 1 to 5, give half a teaspoon. For ages 6 to 11, try a full teaspoon. Kids 12 and older can have up to two teaspoons. You can give it straight or stir it into warm water or warm decaffeinated tea. Give it about 30 minutes before bedtime for the best effect on nighttime coughing.
Never give honey to a baby under 12 months old. Honey can contain spores that cause infant botulism, a rare but serious illness. This rule applies to all forms of honey, including pasteurized varieties and products that contain honey as an ingredient.
What Works for Babies Under 1
Options are most limited for infants. No cough medicines and no honey leaves parents with just a few tools, but they can make a real difference. Saline (saltwater) nose drops followed by gentle suction with a bulb syringe or nasal aspirator help clear mucus that triggers coughing. For babies 3 months and older, a small amount of warm clear fluid like water or apple juice (about one to three teaspoons, a few times a day) can thin mucus and soothe the throat.
Running a cool-mist humidifier in the baby’s room adds moisture to the air and can ease the dry, irritated airways that make coughing worse at night. Clean the humidifier daily to prevent mold buildup.
Remedies for Toddlers and Older Children
Once a child is past their first birthday, honey becomes the go-to. But several other strategies help alongside it:
- Warm fluids. Warm water, broth, or caffeine-free tea soothes the throat and loosens mucus. Encourage frequent small sips throughout the day.
- Cool-mist humidifier. Especially useful at night when coughs tend to worsen. Avoid warm-mist humidifiers, which pose a burn risk around children.
- Saline nasal spray or drops. Helpful for post-nasal drip, which is one of the most common reasons children cough. Clearing the nose reduces the mucus dripping down the back of the throat.
- Elevating the head. For children old enough to sleep with a pillow (generally over age 2), a slight elevation can reduce nighttime coughing caused by mucus pooling in the throat.
- Hard candy or cough drops. Only for children over age 4 due to choking risk. These work by stimulating saliva production, which soothes the throat. They don’t contain medicine that suppresses the cough reflex in any proven way, but the soothing effect is real.
When OTC Medicine Might Be Appropriate
For children 6 and older, you may consider an over-the-counter cough product if the cough is disrupting sleep or daily activities and home remedies haven’t helped. Look at the active ingredients and understand what each type does.
Cough suppressants (containing dextromethorphan, often labeled “DM”) are designed to reduce the urge to cough. These are intended for dry, hacking coughs with no mucus production. Expectorants (containing guaifenesin) are meant to thin mucus so it’s easier to cough up. These make more sense for wet, productive coughs. Avoid combination products that treat multiple symptoms at once, since they increase the chance of giving your child an ingredient they don’t need or accidentally doubling up if you’re also giving a separate fever reducer.
Always use the measuring device that comes with the product, not a kitchen spoon. Follow the weight-based dosing on the label when available, since weight is more accurate than age for determining the right amount.
Coughs That Need Medical Attention
Most coughs in children are caused by common viral infections and clear up within one to two weeks. Some coughs signal something that needs a closer look. A barking cough that sounds like a seal, especially with noisy breathing when inhaling, suggests croup. Wheezing or difficulty breathing could point to asthma or a lower respiratory infection. A cough lasting more than three weeks, a cough with high fever (above 104°F), or a cough in a baby under 3 months old all warrant a call to your child’s doctor.
A sudden onset of coughing in a toddler who was fine moments earlier, especially without any cold symptoms, raises the possibility of a swallowed or inhaled object. This needs immediate medical evaluation.
Medicines to Avoid
Codeine and hydrocodone, both prescription opioid cough suppressants, should not be used in children under 18. The FDA issued this restriction because some children metabolize these drugs too rapidly, leading to dangerously slowed breathing. Some older prescribing practices haven’t caught up with this guidance, so if a provider prescribes a codeine-containing cough syrup for your child, it’s worth asking about alternatives.
Aspirin should never be given to children or teenagers with a viral illness due to the risk of Reye’s syndrome, a rare but life-threatening condition. If your child needs a pain reliever or fever reducer alongside their cough, acetaminophen or ibuprofen (for children 6 months and older) are safe choices at the correct dose for their weight.
