What is a TENS machine in Australia?

A TENS machine—short for Transcutaneous Electrical Nerve Stimulation—is a small, portable device that sends mild electrical currents through the skin via electrode pads placed on the body. In Australia, the government health information service Healthdirect Australia describes it as a method of pain relief that works by stimulating nerves to block pain signals and help the body release natural painkillers called endorphins.

How TENS works

The mechanism is straightforward: adhesive electrode pads attach to the skin near the painful area, and the TENS unit delivers controlled electrical pulses. According to Healthdirect Australia, the device operates at a safe 9 volts and does not involve medicines or needles. TENS Machines Australia explains that the device works through two mechanisms: sensory level stimulation that blocks pain signal transmission, and motor level stimulation that causes the release of endogenous opiate-like substances similar to the body’s own pain-relieving compounds.

TENS vs other pain relief

Unlike medications, TENS machines produce no systemic side effects or risk of drowsiness. They are drug-free, non-invasive with no internal devices or injections required. The Australian Massage Therapy Association notes that the Therapeutic Goods Administration (TGA) sets quality standards for these medical devices to ensure they are manufactured to a high standard. According to Healthdirect Australia, there is good evidence that using TENS reduces pain during or right after treatment and does not cause serious side effects.

“There is good evidence that using TENS reduces pain during or right after treatment and does not cause serious side effects.”

Bottom line: TENS machines offer a drug-free, non-invasive pain relief option regulated by Australia’s TGA, with Healthdirect Australia confirming evidence for pain reduction during and immediately after treatment.

Is it worth buying a TENS machine?

For many Australians, the answer is yes—but the value depends on your specific pain situation, how often you’ll use it, and whether you understand its limitations. TENS machines are widely recommended by midwives and physiotherapists across Australia for labour support, and they have become a popular tool for managing chronic pain at home.

Pros and cons

Upsides

  • Drug-free with no risk of drowsiness or medication interactions
  • Non-invasive—no needles or internal devices
  • Portable for use at home or on the go
  • Battery powered—no power cord restrictions
  • Reusable with replaceable electrode pads
  • Can reduce reliance on pain medications
  • Suitable for early labour to delay stronger interventions

Downsides

  • Some users experience skin irritation at electrode sites
  • The sensation can be uncomfortable for some people
  • Not waterproof—cannot be used in shower or bath
  • Requires proper electrode maintenance for effectiveness
  • May not be suitable for all pain types
  • Long-term safety studies remain limited

Cost comparison

Basic TENS units start at budget retailers, while specialised labour TENS devices with features like a boost button can cost more. TENS Machines Australia notes that units are very easy to use and portable. Healthdirect Australia recommends hiring machines for home use if you only need them for a specific period—like during labour—rather than purchasing outright.

The trade-off

For labour use, hiring a TENS machine may offer better value than buying, since units are typically needed for a limited time and come with professional guidance.

Bottom line: TENS machines are worth buying for regular chronic pain sufferers, while hiring makes more sense for one-time use like labour preparation.

Do Chemist Warehouse sell TENS machines?

Yes, Chemist Warehouse stocks TENS machines both online and in-store at locations across Australia, making them one of the most accessible retail options for purchasing a unit. Beyond this major pharmacy chain, several dedicated suppliers operate in the Australian market.

Other Australian retailers

The market includes both broad-retail and specialist options. TENS Machines Australia and CareMax Australia operate as dedicated suppliers offering device purchase and sometimes hire options. CareMax notes their TENS machines meet Australian standards and are TGA-approved. Healthdirect Australia confirms that TENS machines can be purchased from manufacturers, medical equipment suppliers, and some pharmacies, and that suppliers should be registered with the Therapeutic Goods Administration.

Online vs in-store

Purchasing online offers convenience and broader product selection, while in-store shopping at Chemist Warehouse allows you to see the unit before buying. Regardless of where you purchase, Healthdirect Australia recommends checking that the supplier is registered with the TGA to ensure compliance with Australian safety standards. TENS unit suppliers should be registered with the Therapeutic Goods Administration to operate legally in Australia.

What to watch

Not all TENS devices sold in Australia are TGA-registered. Before purchasing, verify the supplier’s TGA registration status to ensure you’re buying a device that meets Australian safety and quality standards.

Bottom line: Chemist Warehouse is a convenient option for TENS purchases, but always verify the supplier is TGA-registered to ensure safety compliance.

Can I use a TENS unit if I have a titanium implant?

This is one of the most important safety questions for anyone considering a TENS machine, and the answer depends heavily on what type of implant you have. Healthdirect Australia is clear that TENS should not be used if you have a pacemaker or other implanted heart devices—this is a firm contraindication, not a precaution.

Contraindications

The list of when NOT to use a TENS machine is substantial and comes from Healthdirect Australia’s safety guidance reviewed in October 2024. TENS should not be used on open wounds or irritated skin, near the eyes, near a tumour or cancer, on the head, chest, or front of neck, while driving or operating machinery, or in or around water. Additionally, Healthdirect Australia states TENS should not be used if you have been diagnosed with epilepsy or if you have certain types of heart disease.

Consultation advice

For anyone with a titanium implant that isn’t a cardiac device—such as orthopaedic implants—the situation is less clear-cut. The research notes indicate that titanium implant compatibility beyond pacemakers requires individual medical assessment. Healthdirect Australia recommends that if you have a new pain, you should not use TENS unless a doctor has advised that it is safe. For pregnant individuals, they recommend contacting a physiotherapist, GP, or midwife for advice before using TENS.

The catch

If you have any type of implanted medical device—whether cardiac or orthopaedic—consult your doctor or specialist before using a TENS machine. The electrical currents could potentially interfere with certain implants.

Bottom line: Cardiac implants (pacemakers) are an absolute contraindication. For titanium orthopaedic implants, you need individual medical clearance before using TENS.

How many times a day should you use a TENS machine?

Getting the frequency right is key to using a TENS machine effectively and safely. Australian health authorities and TENS suppliers offer guidelines on daily usage limits and session duration to help you get the most benefit without overdoing it.

Usage guidelines

The standard recommendation across Australian health guidance is to use TENS in sessions lasting around 20 to 30 minutes. Healthdirect Australia notes that TENS machines can reduce pain during use, improve relaxation, improve sleep, and reduce the need for pain medicines. TENS Machines Australia recommends that if the cause of pain is unknown or undiagnosed, you should not use TENS until a medical professional has assessed your condition.

Session duration

Most guidelines suggest limiting TENS use to avoid skin irritation from prolonged electrode placement. A typical approach is to use it several times per day as needed, but not continuously. The goal is to manage pain during specific activities or periods rather than using it constantly throughout the day. If you find the sensation uncomfortable, Healthdirect Australia notes that TENS should not be painful, though some people do find it uncomfortable at higher intensity levels.

The upshot

For most users, 20-30 minute sessions, several times per day as needed, aligns with Australian health guidance. If you need more than this, consult a physiotherapist or GP to ensure your usage pattern is appropriate.

Bottom line: Use TENS in 20-30 minute sessions as needed, typically several times daily. Continuous all-day use is not recommended without medical guidance.

TENS Machine Specifications

Three common models illustrate what’s available across the Australian market, from general-purpose units to specialised labour devices.

The pattern across these TGA-registered devices shows that labour-specific models include boost buttons for contraction management, while general chronic pain units focus on steady output settings.

How to Use a TENS Machine

Using a TENS machine correctly is essential for both safety and effectiveness. Follow these steps to get started with your device.

  1. Get professional advice first. Before using a TENS machine, Healthdirect Australia recommends consulting a physiotherapist, GP, or pharmacist—particularly if you’re pregnant, have underlying health conditions, or are unsure about the cause of your pain.
  2. Check your supplier is TGA-registered. Verify that your TENS machine supplier is registered with Australia’s Therapeutic Goods Administration to ensure the device meets Australian safety standards.
  3. Read the device manual. Familiarise yourself with your specific model’s controls, intensity levels, and electrode placement instructions before applying it to your body.
  4. Prepare the skin. Clean and dry the skin where you’ll place the electrode pads. Avoid applying lotion or oil in those areas.
  5. Place electrodes correctly. Position the pads on either side of the painful area, not directly on it. The electrode placement guide in your manual shows recommended positions for different body areas.
  6. Start at low intensity. Begin with the lowest setting and gradually increase until you feel a strong but comfortable tingling sensation. TENS should not be painful.
  7. Limit session duration. Use for 20-30 minutes per session. You can use it several times per day as needed, but avoid continuous all-day use.
  8. Monitor for skin irritation. Remove the electrodes immediately if you experience skin redness, irritation, or discomfort at the electrode sites.
Why this matters

Proper electrode placement and appropriate intensity settings make the difference between effective pain relief and skin irritation or discomfort. Take time to learn your device’s settings rather than rushing into use.

The implication for first-time users is that investing 15 minutes in setup and gradual intensity increases prevents the most common complaints—skin irritation and discomfort—while maximising pain relief outcomes.

Frequently asked questions

What are the dangers of TENS machines?

Healthdirect Australia identifies several dangers: TENS should not be used with pacemakers or implanted heart devices, on open wounds, near the eyes, over tumours, on the head/chest/neck, while driving, in water, or by people with epilepsy. Some users also experience skin irritation where electrodes are placed.

Is TENS safe during pregnancy?

TENS should not be used before 37 weeks of pregnancy unless under medical supervision. From 37 weeks, it is considered safe for labour use. Pregnant individuals should always consult their GP, physiotherapist, or midwife before using TENS to manage pain.

How does TENS help with labour pain?

According to Elle TENS, TENS helps manage labour pain by delivering controlled electrical pulses that stimulate nerves and trigger the body’s natural painkillers (endorphins). The handheld design with a boost button allows the user to control intensity throughout labour contractions. Healthdirect Australia notes TENS is ideal for early labour whether at home or in hospital and can delay or reduce the need for stronger interventions.

Can I use TENS on my back?

Yes, TENS can be used on the back for pain relief. Electrode pads should be placed on either side of the painful area, not directly on the spine. Avoid placing electrodes on the front of the chest or neck area. If your back pain is new or undiagnosed, consult a doctor before using TENS.

What pads do I need for TENS?

TENS machines use reusable adhesive electrode pads that attach to the skin. Pads need to be replaced when they lose their stickiness, typically after 10-30 uses depending on skin type and care. Use only genuine replacement pads compatible with your specific device to maintain proper stimulation quality and skin safety.

Are TENS machines covered by Medicare?

General TENS devices are typically not covered by Medicare as they are classified as consumer medical devices rather than prescribed therapeutic equipment. However, coverage may be available in specific circumstances through chronic disease management plans or workplace injury claims. Check with Medicare or your healthcare provider for your specific situation.

How to choose a TENS machine?

Consider the intensity levels (more settings offer finer control), battery life, electrode pad quality, and whether you need features like a boost button for labour use. Verify the supplier is TGA-registered, and choose a device appropriate for your specific pain condition. For labour use, specialised labour TENS units offer features not found on general-purpose devices.

For Australian consumers, the decision is straightforward: if you need drug-free pain management for chronic conditions or labour, a TENS machine registered with the TGA and purchased from a verified supplier like Chemist Warehouse or a specialist retailer gives you a safe, evidence-supported option to discuss with your GP or physiotherapist.
