For acute lateral epicondylitis, how would you plan an iontophoresis treatment?

• A. Administer a corticosteroid iontophoresis (e.g., dexamethasone) for inflammation, followed by a brief analgesic modality; time and current per device protocol
• B. Iontophoresis with distilled water only
• C. Use iontophoresis with saline only
• D. Apply only a heat pack before iontophoresis

Answer: (A)

In acute lateral epicondylitis, the goal of iontophoresis is to deliver anti-inflammatory medication directly to the inflamed tendon area using electrical current, so you get targeted relief with minimal systemic effects. Using a corticosteroid like dexamethasone phosphate leverages its anti-inflammatory action right at the site of irritation. Because dexamethasone carries a negative charge, you place it under the electrode that matches that charge to drive the medication into the tissue effectively, and you follow the device’s recommended time and current settings to ensure safe, sufficient dosing.

After delivering the drug, a brief analgesic modality helps control pain and supports comfort as the anti-inflammatory effect begins. Following the device protocol for duration and intensity ensures you don’t over- or under-treat.

Options that use distilled water or saline alone wouldn’t deliver an anti-inflammatory agent, so they don’t address the inflammatory process directly. Applying heat beforehand isn’t ideal in the acute phase, as it can increase inflammation and edema; the typical approach is to use anti-inflammatory drug delivery with iontophoresis and then apply a modality aimed at relief and tissue recovery within safe, protocol-guided parameters.
