FlexEze Heat Patch — Single
TGA-registered air-activated heat patch — 12 hours of continuous low-level heat therapy for back pain, muscle aches, and joint stiffness.
Continuous low-level heat in a flexible single-use patch
FlexEze Heat Patch is a single-use, air-activated heat patch manufactured by FlexEze, a 100% Australian-owned company operated by healthcare professionals.
It is registered on the Australian Register of Therapeutic Goods as a medical device, a higher regulatory category than the listed medicines and wellness products elsewhere in our stock range. As a TGA-registered medical device, FlexEze has been assessed for safety and performance, and its clinical use in major Australian hospitals has been validated through published research.
The patch measures approximately 10cm x 13cm and produces up to 12 hours of continuous low-level heat at approximately 40°C when exposed to air. It is drug-free, odourless, and flexible enough to move with the body.
At Lakeside Chiropractic we sell single patches. They are ideal for patients who want to trial the product, use it intermittently, or purchase one to use alongside the FlexEze Body Wrap.
Simple air-activated heat science
FlexEze patches generate heat through a simple, well-understood exothermic reaction.
The contents — iron powder, activated charcoal, vermiculite, salt, and water — are sealed in an oxygen-proof packet. When the packet is opened, the iron powder reacts with oxygen from the air through oxidation to produce heat. This is the same controlled rusting process used in hand warmers and surgical warming products worldwide.
Drug-free and odourless
Iron powder, activated charcoal, vermiculite, salt (sodium chloride), and water.
The contents are eco-friendly and biodegradable. After use, the contents can be emptied into garden soil where they act as a soil conditioner. The patch contains no medications, fragrances, or latex.
Portable heat therapy that supports movement
FlexEze delivers sustained, low-level heat to the site of pain without reheating, plugging in, or staying still.
Continuous heat
Delivers continuous low-level heat at approximately 40°C for up to 12 hours at the site of pain.
Muscle relaxation
Relaxes tight and tense muscles by increasing local tissue temperature and improving tissue extensibility.
Circulation support
Increases local blood circulation, improving oxygen and nutrient delivery to affected tissue.
Pain modulation
Reduces pain perception through thermoreceptor activation, a well-established mechanism of heat analgesia.
Drug-free support
Non-invasive heat therapy with no systemic effects, suitable for patients who cannot or prefer not to use oral analgesics.
Evidence-supported heat wrap therapy
Continuous low-level heat wrap therapy has one of the strongest evidence bases of any non-pharmacological intervention for acute and subacute low back pain.
- More effective than ibuprofen and paracetamol for acute low back pain: A 2002 RCT found continuous low-level heat wrap therapy provided significantly greater pain relief than ibuprofen or acetaminophen in acute non-specific low back pain.
- Heat plus exercise outperforms either alone: A 2005 RCT found that combining heat wrap therapy with exercise produced greater functional improvement than either heat alone, exercise alone, or control.
- Used in Australian hospital emergency departments: FlexEze participated in a clinical care model trial at four major NSW hospitals published in BMJ Open.
- Recommended in Australia's Clinical Care Standard for Low Back Pain: Heat wraps with physical activity are recommended as a first-line non-pharmacological treatment for acute low back pain.
- Useful beyond back pain: Heat mechanisms also apply to neck and shoulder tension, knee stiffness, menstrual pain, muscular aches, and joint discomfort from mild osteoarthritis.
- Fits chiropractic care: Heat may help reduce muscle guarding and support active movement between visits.
Key evidence
Single patches for flexible use
Use a single patch with the FlexEze Body Wrap or adhere it to clothing over the area of pain.
Single patch pouch
Open only when ready to use because the patch activates immediately on exposure to air.
12-hour heat therapy
Designed for back pain, joint stiffness, and muscle aches with sustained soothing heat.
Sold individually
A practical option for patients who want to trial the product or use it intermittently.
Apply to clothing only, not directly to skin
- Open the outer foil pouch only when ready to use. The patch activates immediately on exposure to air.
- If using with the FlexEze Body Wrap, insert the patch into the wrap pocket without removing the adhesive backing paper, with the paper side facing away from your body.
- If using without the body wrap, remove the protective backing paper and adhere the patch to the inside of your clothing over the area of pain. Do not apply the adhesive directly to skin.
- Allow 30 minutes for the patch to reach full temperature. Heat will be felt within minutes of opening.
- Wear for up to 12 hours. Do not use on the same area for more than 12 hours in any 24-hour period.
- Do not use while sleeping, overnight, or with tight waistbands or belts pressing directly on the patch.
- If the patch becomes too hot or skin sensitivity occurs, remove it immediately.
- The patch is single use. Once it has gone cold and hardened, it cannot be reactivated.
- Disposal: empty the cooled contents into garden soil as a soil conditioner. Dispose of outer packaging in general waste.
Important — please read before use
- Do not apply the adhesive directly to skin. Always apply to clothing only, or use with the FlexEze Body Wrap.
- Do not use while sleeping or overnight — unsupervised use increases the risk of burns.
- Do not use on broken skin, bruises, open wounds, or swellings.
- Do not use in combination with other heat sources on the same area simultaneously.
- Do not use on infants or children under 12 years old, or on anyone who cannot remove the patch themselves if it becomes uncomfortable.
- Consult your chiropractor or doctor before use if you have diabetes, poor circulation, peripheral neuropathy, rheumatoid arthritis, impaired skin sensation, or are pregnant.
- Do not cut, fold, or knead the patch.
- Keep out of reach of children and animals. If contents are ingested or enter the eyes, rinse with water and seek medical advice.
- Your risk of skin burns increases with age and with prolonged or repeated application. Monitor frequently during use, especially for the first hour.
