How long does a 4mA direct current treatment last?
For example, if the patient comfortably receive 4mA of direct current, then the treatment would last 10 min (4mA x 10 min = 40mA - min). The challenge is that patients have varying sensitivities to current and varying nutritional and skin status, so when current is reduced for patient comfort, treatment times are longer (40mA - min dose at 2.0mA is now a 20 min treatment).

What is a patch containing a positive and negative electrode?
A patch containing a positive and negative electrode adheres directly to the skin. One end of the electrode is filled with the selected medication, and the other is filled with standard saline (NaCl). Patches contain a buffering agent that minimize the chances of a burn. Electrode configurations and shapes vary.
How does applying a charge to the skin affect the flow of ions through the skin?
The repulsive effects between the medication and the active electrode. Applying a charge to the skin changes the flow of ions through the skin, reducing it's resistance and enhancing the amount of and type of medication that can travel below the skin's surface to produce a therapeutic dosing effect.
How deep do ions penetrate the tissues?
It is usually considered that the penetration of the ions into the tissues is likely to be less than 1mm. Any deeper penetration is considered to be due to local capillary circulation effects. There is no evidence that the current itself is responsible for penetrations beyond this level (though some authors claim - without explicit evidence - that the ions are driven much further into the tissues. The bulk of the ions that enter the tissues accumulate under the stimulating electrode and it may be possible that recombination of the substance can occur under this (active) electrode, though this remains a controversial issue which has not been fully resolved by the available research evidence.
How long does an electrode patch last?
The electrode patch is preconfigured and delivers a smaller current than is normally employed in the department or clinic (typically 0.1mA). The patch is applied for 12 - 24 hours (depending on the intended dose) after which time, it is removed and disgarded (they can not be reused). The illustration of electrode systems (below) includes one such option (top right)
Can iontophoresis be specific?
