If you used to order iHerb melatonin gummies for your child, you may have noticed the changes. iHerb paused melatonin sales to Australian customers in August 2025, and many parents are now unsure where to turn.

This change hit a lot of families hard. Bedtime battles are exhausting, and a gummy that seemed to help can feel impossible to replace.

There is a safe and legal path for children who need sleep support. It starts with good sleep habits and, where needed, a conversation with a doctor who knows your child.

In this guide, the HolisticChem pharmacy team in Bayswater explains what changed with iHerb melatonin, what Australian law says about melatonin for children, and what to do next. We keep it simple, judgement free and focused on your child's safety.

Why Did iHerb Stop Shipping Melatonin to Australia?

iHerb paused melatonin sales to Australia in August 2025 after poisons centres reported a sharp rise in calls about melatonin, mostly involving children. Many of these cases involved children eating gummies that looked and tasted like lollies.

The Western Australian Poisons Information Centre reported a jump in melatonin calls from 175 in 2018 to 322 by August 2025. Pharmacists at the centre said most calls were accidental, often after a child found gummies left on a kitchen bench.

AusDoc reported that the pause also exposed a wider problem. Many Australian parents had been buying melatonin from US websites without a prescription, even though Australian law requires one.

As of September 2026, iHerb's Australian site lists melatonin again, but each product carries a notice that Australian authorities may ask for proof of a valid prescription and that orders without one could be stopped at customs. Before ordering from iHerb or any other overseas website, it helps to understand the Australian rules explained below.

Is Melatonin Legal for Children in Australia?

Melatonin is not banned in Australia, but children need a prescription to use it. Melatonin for anyone under 55 is a prescription only medicine, so a doctor decides whether it suits your child.

The only over the counter melatonin in Australia is a 2 mg prolonged release tablet that a pharmacist can supply to adults aged 55 and over, according to WhichMedicine's summary of the scheduling rules. Every other melatonin product, including gummies, liquids and higher strengths, needs a prescription.

For children, the Therapeutic Goods Administration (TGA) has registered one prolonged release melatonin tablet for insomnia. Healthdirect lists its approved uses as children aged 2 to 18 with autism spectrum disorder or certain neurogenetic conditions, and children aged 6 to 17 with ADHD, when sleep habits alone have not helped enough.

For other children, a doctor may still decide melatonin is appropriate. This is a clinical decision made case by case, based on your child's health and history.

Why Are Imported Melatonin Gummies Risky for Children?

Imported melatonin products are not checked by the TGA, and testing has found many do not contain the dose on the label. Some contain far more melatonin than stated, and some contain none at all.

In September 2025, the TGA warned Australians after testing found significant dose inconsistencies in melatonin products bought from overseas websites. Some samples held up to 400% more melatonin than the label claimed.

That matters most for small children. A child given a gummy labelled 1 mg could be getting several times that dose, and a parent would have no way to know.

Gummies add a second risk. Children see them as lollies, and Australian poisons hotlines took around 1,500 calls about children swallowing melatonin in a single year.

If you still have melatonin gummies at home, store them up high and locked away, the same way you would store any medicine.

What Happens If You Order Melatonin From Overseas?

Melatonin ordered from overseas without a prescription can be stopped at the border and destroyed. You may lose both the product and the money you paid for it.

The Australian Border Force intercepted about 150,000 units of melatonin between September and December 2025. The TGA reviews each referral and can seize products that were not lawfully imported.

The TGA also warns that unapproved melatonin products have not been assessed for safety, quality or effectiveness. Switching to a marketplace or another overseas website carries the same risks.

A safer path is to go through an Australian doctor and pharmacy. Medicines supplied this way follow Australian rules and come with dosing advice from a pharmacist.

Build These Sleep Habits Before Trying Any Medicine

Children's sleep specialists recommend good sleep habits as the first step for most sleep problems. The Royal Children's Hospital Melbourne advises that melatonin is worth discussing only after a consistent routine, behavioural strategies and removing screens have not worked.

These habits come from the Royal Children's Hospital and the Sleep Health Foundation:

• Keep bedtime and wake time within about an hour of each other every day, including weekends.

• Start a calm routine about 30 minutes before bed, such as a bath, a story or quiet reading.

• Take phones, tablets and TVs out of the bedroom. Screen light can delay the body's own melatonin release.

• Avoid caffeine after midday, including cola, tea and chocolate.

• Get outside for active play during the day, and keep the last hour before bed quiet.

• Talk about worries during the day rather than at bedtime.

The Raising Children Network has more practical tips for school age children. Stick with new habits every night so your child's body clock has time to adjust.

When Should You Talk to a Doctor About Your Child's Sleep?

Talk to your GP or paediatrician if sleep problems continue after you have tried a steady routine, or if they affect your child's mood, learning or family life. You should also see a doctor before giving your child melatonin of any kind.

The Royal Children's Hospital also suggests seeing a doctor if your child has regular distressing nightmares, an ongoing health issue that affects sleep, or signs of anxiety.

Before the appointment, keep a simple sleep diary for one to two weeks. Note bedtime, how long your child takes to fall asleep, night waking and wake time.

If your child was taking an imported melatonin product, bring the bottle. Tell the doctor the dose on the label and how often your child took it.

How Does a Compounding Pharmacy Help With Children's Prescriptions?

A compounding pharmacy prepares a medicine to match a doctor's prescription when a standard product does not suit the patient. For children, this often means a liquid or a smaller strength that is easier to take.

Compounding only happens once a doctor has written a prescription. The pharmacist prepares the exact dose the doctor ordered and explains how to give and store the medicine.

HolisticChem runs an in house compounding pharmacy at our Bayswater pharmacy, including paediatric preparations made to prescription. Our guide to what a compounding pharmacy does explains the process in more detail.
