Which of the following is an indication for iontophoresis?

• A. Pain
• B. Hypertension
• C. Hyperlipidemia
• D. Diabetes

Answer: (A)

Iontophoresis uses a small electric current to push charged medication into superficial tissues, allowing targeted relief of localized symptoms. That makes pain a primary indication because you can deliver analgesic or anti-inflammatory drugs directly at the painful site, reducing local inflammation and discomfort with minimal systemic exposure.

Hypertension, hyperlipidemia, and diabetes are systemic conditions requiring systemic treatments and management strategies, not localized drug delivery through the skin. Iontophoresis won’t meaningfully alter blood pressure, lipid levels, or glucose control, since it acts mainly on a limited area of tissue rather than the whole body.
