Children tend to develop fevers more easily than adults. This comes mostly from having a relatively undeveloped immune system which makes them more vulnerable to various infections (the most common cause of fevers). KOOLFEVER is designed with this in mind, providing quick and effective relief from fevers that enhances their well-being, as well as eases the concerns of anxious parents.

KOOLFEVER, Japan’s best selling fever relief pad was initially developed to provide effective and convenient relief for children suffering from a fever. The popularity of our product has since encouraged us to develop a range of fever relief pads for babies and adults. Through extensive testing, research and the use of technological advancements, KOOLFEVER fever relief pads now bring quick, effective relief and an enhanced feeling of well-being.

Kobayashi Pharmaceutical is committed to applying our expertise and research based on unique ideas to create effective, safe and convenient products for everyone.



General questions

Q01. My child licked/ate the product.  Is this a problem?

A01. With your safety in mind, we have designed the product to contain only ingredients that are commonly used in items such as pharmaceuticals and off-the counter medication.

Therefore, there should not be any problem if the product is licked or eaten.  However, please consult a physician if you notice anything your child having an adverse reaction.

Q02. Is it okay for people with atopic dermatitis to use the product?

A02. This product has been designed for users with normal skin. Please avoid using KOOLFEVER if you have a skin condition.

Q03. How should I remove the gel when it gets stuck on clothing or underwear?

A03. First, remove as much as possible by hand. The remainder can be removed by washing as normal, either by hand or in a washing machine.
Please note that the adhesiveness differs for different types of clothing:

  • Highly adhesive to: Cotton, polyester, acetate, acrylic blankets
  • Slightly adhesive to: Flannel, cotton towels
  • Will stain: Silk

Q04. Why does it peel off straight away?

A04. The sheet will not attach well if the skin is wet or greasy. When this happens, try wiping the skin a clean towel first before re-attaching the sheet.

Also, with small children, one whole sheet can be too large for the forehead, and this will make it more likely to peel off.  In this case, please cut the sheet to a suitable size before attaching the sheet.

KOOLFEVER for Babies

Q01. The gel melted and got into the baby's eyes. Is this a problem?

A01.  Please rinse immediately with water. Although the ingredients are extremely safe, please seek medical attention immediately if your baby shows signs of pain or an adverse reaction.

Q02. How is KOOLFEVER for babies different to KOOLFEVER for children?

A02.  KOOLFEVER for babies is designed to achieve an optimum temperature for the baby so that the sheet will not cool the baby’s skin too much.  Also, the product does not contain any skin irritants such as coloring or perfume. Furthermore, the size of the sheet is designed to be an exact fit for babies’ foreheads.

Q03. How soon can this product be used on babies?

A03. Please use it on babies aged 6 months and above.

KOOLFEVER for Children

Q01. Are there other effective ways of attaching the sheet?

A01. Besides the forehead, the product can be more effective when attached to areas where the skin temperature is high, for example on the back of the neck, on the armpits or inside the thighs.

Q02. How should the sheet be removed when it gets stuck to hair?

A02. Wipe it off with a hot moistened hand towel.

Q03. Can it be used on burns?

A03. KOOLFEVER reduces the heat generated by the body and cools as the moisture in the gel evaporates. It therefore has a slow and gradual cooling effect which is not suitable for the treatment of burns.

  Emergency treatment for burns would require the affected area to be cooled rapidly and it is advisable to do so through the use of running water and ice bags. Please seek medical attention if your child’s condition does not improve.

Q04. Is it okay that the gel on the products has changed to a green color?

A04. Condensation can occur during the maturation process before shipping. This can cause the sheets to absorb the moisture from the condensation and change colour.

When this happens, the cooling sensation and adhesiveness will be reduced. Do contact us and we will replace them with non-defective products.

Q05. How should unused sheets be stored? And how long can it be stored before use?

A05. Fold firmly twice along the dotted lines on the individual package and then place the package back in the box for storage.

Please use the product as soon as possible, when necessary, as the moisture in the gel will slowly evaporate off as time passes.

There is no particular use-by date, but if the packaging remains unopened then the product can be stored for about 3 years.

Q06. Is it okay to attach this product over the eyes when the eyes are tired?

A06. No problems were found when testing this product during eye irritation tests. However, the skin around the eyes is extremely thin and delicate, so using this product for tired eyes is not recommended. Please use our “Eye-Cooling Sheets” for tired eyes.

KOOLFEVER for Adults

Q01. How is KOOLFEVER for Adults different to KOOLFEVER for children?

A01. The size of the sheet is slightly larger than the product for children. Also, KOOLFEVER for adults contains more menthol to assist in the cooling of the skin.
