Understanding corticosteroid potency

Potency is a comparison of anti-inflammatory effect under defined conditions; it is not a simple measure of quality. A stronger product may be useful for a particular thick or severely inflamed area, while a milder option may suit sensitive skin or a maintenance plan. Absorption also varies with the body site, the amount applied, damaged skin, and whether the area is covered. An injected medicine has different considerations from a cream or tablet. The prescribed strength should therefore match the clinical problem.

Use the named product and instructions rather than judging strength by packaging or by someone else’s experience. Confirm the treatment area, amount, frequency, and intended duration. Tell the clinician about thin or easily bruised skin, acne, infections, eye disease, pregnancy, and other medicines. Do not layer products or cover the area unless instructed. If an injection is planned, ask what structure it targets and how follow-up will work. See Corticosteroid for broader context.

Arrange prompt medical advice for spreading redness, warmth, pus, fever, significant skin thinning, new persistent acne-like changes, or worsening symptoms. Seek urgent help for facial or throat swelling, breathing difficulty, severe eye pain, or vision change. A stronger product is not a solution for a diagnosis that has not been confirmed.

Why is this potency appropriate for my body site and diagnosis? How much should I use, for how long, and what changes would mean that the treatment needs review?
