Fluocinolone Acetonide (Topical)

How it works

It binds intracellular glucocorticoid receptors to suppress release of inflammatory mediators, producing local anti-inflammatory, vasoconstrictive and antiproliferative effects in the skin.

Prescribing in practice

• As a potent topical steroid, prolonged or extensive use—especially under occlusion, on the face/flexures, or in children—risks skin atrophy, striae and systemic absorption, so apply thinly to the smallest effective area for the shortest time.
• Avoid use on untreated bacterial, fungal or viral skin infections unless combined with appropriate antimicrobial cover.
• Step down to a less potent preparation once the flare is controlled and review continued need.

Monitoring

Monitor the treated skin for signs of atrophy, telangiectasia or worsening infection, and reassess if there is no improvement within the expected period.

Counselling the patient

• Apply a thin layer only to the affected areas and wash hands afterwards unless the hands are being treated.
• Do not use on the face or skin folds for prolonged periods unless specifically advised.
• Continue any prescribed emollients, separating their application from the steroid.

Evidence & guidelines

Use of topical corticosteroids by potency and quantity (fingertip units) follows established NICE and MHRA guidance on safe topical steroid use.
