Medicplast Terracool (Child & Adult)

Medicplast Terracool (Child & Adult) is a non-medicated hydrogel cooling patch manufactured by Jase Healthcare, described by retailers as suitable for use from 6 years of age through to adults, and sold through DoctorOnCall Malaysia in pack sizes of 2 and 12 sheets.

The patch is built on a hydrogel base containing menthol, designed to sit flat against the skin, and is marketed by the manufacturer as hypoallergenic and fragrance-free. It also includes a thermochromic indicator strip that changes colour in response to skin temperature, a feature some users find helpful for tracking changes at the application site over time.

As an externally applied hydrogel patch rather than an oral or injectable medicine, Medicplast Terracool (Child & Adult) contains no active pharmaceutical ingredient and is classified as a non-medicated cooling patch. It is sold over the counter and does not require a doctor’s prescription, and is part of the same Jase Healthcare product range as the Mr. Throat lozenges.

• Peel off the protective film from the patch.
• Apply the patch to clean, dry, unbroken skin on the forehead or another suitable area.
• Press down gently so the patch adheres evenly.
• Remove and replace the patch once the cooling sensation fades or after the duration stated on the packaging.

As a topical hydrogel patch rather than a medicine, Medicplast Terracool (Child & Adult) does not have a drug dose. One patch is applied at a time to the forehead or another suitable area of skin, and the manufacturer describes a cooling duration of up to 8 hours per patch; replace it when the cooling sensation wears off or sooner if the skin underneath becomes irritated. Do not apply more than one patch to the same area of skin at the same time.

Use before the expiry date printed on the individual sachet or outer box. Once a sachet is opened, use the patch promptly, as hydrogel patches can dry out and lose their cooling effect if left exposed to air for an extended period.

Store in a cool, dry place away from direct sunlight and heat. The manufacturer notes that refrigerating an unopened sachet (not freezing it) can enhance the cooling sensation on application, though this step is optional. Keep sealed sachets out of reach of young children until ready to use.

• Common: Mild, temporary redness at the site where the patch was applied.
• Common: A slight tingling sensation from the menthol content.
• Serious: Skin irritation, itching, or a rash that spreads or does not settle after the patch is removed, which should be checked by a doctor or pharmacist.

• Known allergy or hypersensitivity to menthol or any other component of the hydrogel.
• Broken, wounded, or actively inflamed skin – this patch is intended for intact skin only.
• Children under 6 years old, as the manufacturer describes this product as suitable from 6 years of age; younger children should only use a cooling patch under medical advice.

• Not applicable in the usual medicine sense – this is a non-medicated topical patch with no active pharmaceutical ingredient and is not known to interact with oral or injected medicines.
• No food interactions apply, as the patch is used externally on the skin rather than taken by mouth.
• Avoid applying this patch at the same time as other topical menthol-containing products on the same area of skin, to prevent excessive local cooling or irritation.

• Apply to a clean, dry forehead for the most even contact and cooling sensation.
• Keep a spare sachet in your bag or travel kit for use away from home.
• Check the thermochromic indicator strip periodically if you find it useful for tracking the application site.
• Avoid applying over makeup, lotion, or sunscreen, as these can reduce how well the patch sticks.
• Use a fresh patch each time rather than reapplying one that has dried out.
• Keep unused sachets sealed until you are ready to apply them.

Precautions: Only apply this patch to intact, unbroken skin, and avoid the eyes and other mucous membranes. Check the ingredient list first if you or your child has a known sensitivity to menthol. This product is described by the manufacturer as suitable for children aged 6 years and above; for younger children, seek advice from a doctor or pharmacist before use.

When to See a Doctor or Pharmacist: If a fever is high, lasts more than a couple of days, or is accompanied by other concerning symptoms, a cooling patch alone is not a substitute for medical assessment – speak to a doctor or pharmacist for appropriate care.
