Iontophoresis involves the administration of medication to the body through the use of electrical currents. It is one of the most important modality in physiotherapy. Physical therapists may use it in extreme situations. If you’re in the area, visit the best San Diego Physical Therapy Clinic.

This medical device delivers mild electric currents to the body to deliver medication across biological membranes. It is most effective when it is submerged under water.

How It Works

Iontophoresis is a method that uses electrical stimulation to deliver medication across membranes to injured tissues. This is used to decrease sweating and also to reduce inflammation and scar tissue.

It works by applying the fundamental principles of electrical polarity. These principles work on the opposite-polarity principle, which states that opposite ions always attract each other. The medication is in a solution of a particular polarity. The electrodes will be placed on your body by your physical therapist. When electric signals from the positive electrode are transmitted the medication will be repelled. This will aid in the absorption into the skin.

Risk factors

There is no special preparation required for iontophoresis. However, patients who have medical conditions such as pacemakers, pregnancy epilepsy, pacemakers, or any other implant like a knee replacement are not eligible for this treatment. Before you go ahead with the treatment make sure you tell your physical therapist.

To ensure no irritation, apply petroleum jelly to any open wounds on your skin. We can help! Visit the #1 Carmel Mountain Ranch Physical Therapy Clinic.


It is not an ideal treatment, but physical therapists use it when there are no other methods to deliver the medicine. You should make sure you aren’t suffering from any medical conditions that prohibit you from using this therapy. If you feel any side effects of the therapy, you should immediately notify your physical therapist in order to prevent further damage.
