Chattanooga IOGEL Iontophoresis Electrodes — 12 Treatment Kits

IOGEL Iontophoresis Electrodes are single-use drug-delivery electrode kits for professional iontophoresis treatments using a compatible external dose controller.

The elongated elliptical design helps clinicians position the active electrode along a tendon or other narrow treatment region. A clear adhesive border makes it easier to see the target site during placement, while the protected EZ Fill Window allows the GelSponge medication reservoir to be filled before the adhesive liner is removed.

IOGEL uses a silver/silver chloride conductive element designed to stabilize pH without a separate chemical buffer. Its GelSponge interface helps maintain complete contact between the medication reservoir and intact skin while providing a low-impedance conductive medium.

Each box contains 12 individually packaged treatment kits. Every kit includes:

Medication, a dose controller, controller lead wires, and any required snap adapters are not included.

Professional-use notice: Iontophoresis medication, polarity, current, total dose, treatment duration, and electrode placement must be determined by an appropriately qualified healthcare professional and used according to the medication, electrode, and dose-controller instructions.

The appropriate size depends on the prescribed medication volume, treatment site dimensions, skin contour, and clinician’s intended current density and dosing plan.

Do not select a larger electrode merely because it holds more medication. The prescribed dose, compatible solution volume, current, polarity, and treatment area must be considered together.

Silver/silver chloride conductive element

IOGEL uses silver/silver chloride rather than a basic carbon-only conductor. Chattanooga states that this technology conducts more efficiently than carbon and helps stabilize pH without chemical buffers.

During direct-current iontophoresis, chemical changes can occur at the electrode interfaces. Proper pH control, complete contact, correct polarity, and appropriate current density are important for comfort and skin safety.

The GelSponge reservoir absorbs the prescribed solution and maintains contact between the medication and the skin. Chattanooga describes it as providing a conductive medium similar to ultrasound gel and helping create complete skin contact with low impedance.

The EZ Fill Window allows the clinician to hydrate the drug reservoir while the adhesive remains protected. This can help reduce the following:

• Medication contacting the adhesive
• Premature sticking during preparation
• Contamination from unnecessary handling
• Leakage before the electrode is placed
• Loss of adhesion during setup

The clear adhesive helps the clinician see the target location, while the elongated profile is designed to follow the general direction of a tendon.

Current Balego listings identify Trivarion as a form-fitting option for curved anatomy, Ionto4 as a four-shape carbon–Ag/AgCl system, and the buffered kit as an Ag/AgCl option with a buffered return electrode and two prep pads.

• The treatment site is curved or irregular.
• A flexible, form-fitting electrode is a priority.
• A 2.0 cc butterfly option is useful.
• The clinic uses the ActivaDose II controller or another confirmed compatible system.

• Square electrode geometry is preferred.
• A 4.0 cc large option is needed.
• A butterfly electrode is part of the clinic’s workflow.
• Carbon–Ag/AgCl electrode construction is specified.

IontoPATCH and ACTIVApatch use self-contained power systems and do not require an external controller or lead wires. IOGEL is a traditional controller-based electrode system.

IOGEL uses stud or snap connections and is marketed for use with Chattanooga iontophoresis equipment. Before ordering, verify:

The ActivaDose II Dose Controller is a current controller option with adjustable direct current and dose settings.

The following is a general overview. The current electrode instructions, controller manual, medication labeling, prescription, and facility procedure take priority.

1. Confirm the treatment order

Verify:

• Medication or solution
• Drug polarity
• Total dose in mA·min
• Treatment current
• Electrode size
• Active-electrode site
• Dispersive-electrode site
• Treatment duration
• Patient contraindications and precautions

2. Inspect the skin

Use only on intact skin. Do not place the electrodes over:

• Cuts
• Abrasions
• Razor nicks
• Active rashes
• Pimples or ingrown hairs
• Infected tissue
• Unhealed wounds
• Recent scar tissue unless specifically cleared

Our detailed Iontophoresis Electrode Directions for Use provides additional site preparation, polarity, dosing, and safety guidance.

3. Remove nearby jewelry

Remove jewelry or metal objects that could touch either electrode or lie in the current pathway.

4. Prepare both sites

Use the included alcohol prep according to the electrode instructions. Clean the active and dispersive sites and allow them to dry fully before application.

5. Fill the drug electrode away from the patient

Place the electrode on a flat working surface with the reservoir facing upward.

Open the EZ Fill Window and apply the prescribed volume of compatible water-soluble medication or solution evenly across the GelSponge.

Do not:

• Fill the electrode while it is on the patient.
• Leave dry areas in the sponge.
• Overfill the reservoir.
• Underfill the reservoir.
• Use a suspended or non-water-soluble preparation unless specifically permitted.
• Allow medication to spread onto the adhesive.

6. Apply the dispersive electrode first

Place the return or dispersive electrode at the prescribed site and press across its entire adhesive surface.

Avoid bony prominences with minimal soft tissue unless the clinician and product directions specifically permit the location.

7. Apply the drug-delivery electrode

Remove the protective liner and use the clear adhesive to align the GelSponge precisely over the target.

Press the adhesive border—not the filled reservoir—onto the skin. Pressing directly over the sponge can encourage leakage.

8. Connect the lead wires

Connect the drug and dispersive electrodes to the dose controller with the correct polarity.

For a negatively charged medication:

• Drug electrode: black or negative
• Dispersive electrode: red or positive

For a positively charged medication:

• Drug electrode: red or positive
• Dispersive electrode: black or negative

The polarity of the drug must be verified from the prescription, medication information, and clinical protocol. (Balego)

9. Deliver the prescribed treatment

Set the exact dose and current ordered for the patient. Monitor comfort, electrode contact, skin response, lead-wire security, and controller alerts.

Our current directions identify a 4 mA maximum and polarity-dependent maximum doses of 80 mA·min for negative-polarity delivery and 40 mA·min for positive-polarity delivery. The current product and controller instructions should always control. (Balego)

10. Remove and discard

After the controller completes its ramp-down:

1. Turn off or disconnect the controller as directed.
2. Remove the drug electrode slowly.
3. Remove the dispersive electrode.
4. Inspect both skin sites.
5. Discard both electrodes and the used prep material.
6. Document the dose, current, medication, placement, and skin response.

Iontophoresis should not be used when the patient has a known adverse reaction to electrical current, an electrically sensitive implanted device such as a pacemaker, or a known sensitivity to the prescribed medication. It should not be applied over damaged skin, across the chest, transcranially, or in the orbital region.

Temporary redness can occur under either electrode, but pain, intense burning, blistering, or progressive irritation is not an expected treatment goal and requires prompt assessment. (Balego)
