Betamethasone Dipropionate (Diprosone)
Is It Right for You?
A complete guide to Betamethasone Dipropionate (Diprosone) — what it treats, how it works, dosages, side effects, and when a clinician may prescribe it following an online consultation.
What Is Betamethasone Dipropionate (Diprosone)?
Diprosone is a brand of betamethasone dipropionate — a potent (class III, Group 3) synthetic corticosteroid available as a cream (0.05%), ointment (0.05%), and lotion (0.05%) for topical application to the skin. It is one of the most widely prescribed potent topical corticosteroids in the UK.
Topical corticosteroids are classified by potency from mild (Class I, e.g. hydrocortisone 1%) through to very potent (Class IV, e.g. clobetasol propionate 0.05%). Betamethasone dipropionate 0.05% is classified as potent — suitable for moderate to severe inflammatory skin conditions on the body, but requiring careful use and strict limitations on duration, body area, and patient population due to its significant potential for local and systemic adverse effects.
Diprosone is a prescription-only medication in the UK. A licensed clinician must assess the indication, extent of skin involvement, and risk factors before prescribing.
What Conditions Is Diprosone Used For?
Diprosone is indicated for the management of plaque psoriasis on the trunk, limbs, and scalp, treatment of moderate to severe eczema, relief of pruritus in lichen planus, and other corticosteroid-responsive dermatoses.
management of plaque psoriasis on the trunk, limbs, and scalp
treatment of moderate to severe flares on the body (not face or flexures)
relief of pruritus and inflammation in cutaneous lichen planus
topical management of skin lesions under specialist supervision
Topical corticosteroids suppress inflammation and relieve symptoms but do not address the underlying immune dysregulation of chronic inflammatory skin diseases. Long-term disease management requires identification and avoidance of triggers, emollient use, and where appropriate, consideration of systemic or biological therapies.
How Does Diprosone Work?
Betamethasone dipropionate exerts its anti-inflammatory effect by diffusing across cell membranes and binding to intracellular glucocorticoid receptors (GRs) in skin cells. The steroid-receptor complex then translocates to the nucleus and acts as a transcription factor, modulating gene expression in the following ways:
Anti-inflammatory effects — glucocorticoid receptor activation induces the expression of lipocortin-1 (annexin-1), which inhibits phospholipase A2. This reduces the release of arachidonic acid, the precursor to prostaglandins, leukotrienes, and other pro-inflammatory lipid mediators. The result is reduced vasodilation, reduced vascular permeability, and suppression of the inflammatory cascade.
Immunosuppressive effects — betamethasone suppresses the expression and release of pro-inflammatory cytokines (IL-1, IL-6, TNF-α, IFN-γ), reduces T-cell activation and proliferation, and decreases the infiltration of inflammatory cells into the dermis and epidermis.
Antiproliferative effects — corticosteroids reduce keratinocyte proliferation, which is clinically relevant in psoriasis where keratinocyte hyperproliferation produces scaling and plaque formation.
Vasoconstriction — topical corticosteroids produce vasoconstriction (blanching) of superficial skin blood vessels, contributing to the reduction of erythema and oedema.
Dosages & Administration
The correct dose depends on the type and severity of infection, age, weight, and kidney function. Always follow your clinician's instructions. The table below is for general reference only.
Administration Tips
Apply a thin layer — the Fingertip Unit (FTU) guidance can help: one FTU (the amount squeezed from a tube from the tip to the first crease of the index finger, approximately 0.5 g) covers an area roughly equivalent to the palm of one hand.
Apply to affected skin only. Avoid application to uninvolved skin to reduce the risk of skin thinning in unaffected areas.
Do not use under occlusion (tight bandages, cling film, nappies, or impermeable dressings) unless specifically directed; occlusion substantially increases systemic corticosteroid absorption.
Do not apply to the face, armpits, groin, or under the breasts. These areas have thin skin with enhanced absorption and are at higher risk of atrophy and striae. A milder corticosteroid should be used in these areas.
Apply emollients (moisturisers) alongside topical corticosteroids to support skin barrier function and reduce steroid requirements.
Taper use — do not stop Diprosone abruptly after prolonged daily use; step down to intermittent use before discontinuing to reduce rebound.
Side Effects of Diprosone
Most side effects are mild and resolve on their own. Serious side effects are rare but require immediate medical attention.
- Skin thinning (atrophy) — with prolonged use; more common in areas of thin skin
- Striae (stretch marks) — particularly on the trunk and axillae
- Telangiectasia (small dilated blood vessels visible under the skin)
- HPA axis suppression — systemic absorption can suppress the hypothalamic-pituitary-adrenal axis
- Cushing's syndrome features — with excessive or prolonged use
- Increased susceptibility to skin infections — corticosteroids suppress local immune defence
Prolonged or excessive use of potent topical corticosteroids can lead to skin dependency. Upon cessation, some patients experience withdrawal symptoms that may be more severe than the original condition.
Drug Interactions
Always disclose all prescription drugs, over-the-counter medicines, vitamins, and supplements to your clinician or pharmacist before starting Diprosone
concurrent systemic immunosuppression increases susceptibility to skin and systemic infections.
drugs that inhibit CYP3A4 (e.g. itraconazole, ritonavir) may theoretically increase systemic exposure from topical corticosteroid absorption in patients using large quantities; clinical significance is low in routine use.
Important Warnings
Betamethasone dipropionate is a potent corticosteroid and must not be used on the face. Facial application — even briefly — risks significant skin atrophy, perioral dermatitis, rosacea-like eruptions, and, with periorbital use, glaucoma or cataracts. A mild corticosteroid (such as hydrocortisone 1%) should be used for facial inflammatory skin conditions.
Potent topical corticosteroids should be used with extreme caution in children and only under specialist supervision. Children have a higher surface-area-to-body-weight ratio, resulting in proportionally greater systemic absorption. Use the mildest effective preparation.
Patients who have used potent topical corticosteroids continuously over long periods should be counselled about topical steroid withdrawal. Sudden discontinuation after prolonged use should be avoided.
Do not apply Diprosone to infected skin unless a concurrent antimicrobial treatment is also being used, as corticosteroids mask the signs of infection and can worsen bacterial, fungal, or viral skin infections.
Speak to a Clinician About Treatment
Getting advice no longer means sitting in a waiting room. Through The GP Service, you can consult with a licensed clinician in minutes — from home, on your lunch break, or wherever works for you. If treatment is clinically appropriate, your clinician can issue a prescription during the consultation. A consultation does not guarantee a prescription.

Diprosone FAQs
Betamethasone dipropionate 0.05% is classified as a potent (Class III) corticosteroid — significantly stronger than over-the-counter hydrocortisone 1% (mild) but not as strong as clobetasol propionate 0.05% (very potent). It should be used only under clinician direction and for appropriate indications on the body.
No. Potent corticosteroids such as Diprosone must not be applied to the face. Even brief or occasional use on facial skin can cause significant and potentially irreversible skin thinning, perioral dermatitis, and rosacea. Mild corticosteroids (1% hydrocortisone) should be used for facial inflammatory conditions, under clinician guidance.
Apply a thin smear — enough to barely cover the affected skin. The Fingertip Unit (FTU) is a useful guide: one FTU (the amount from fingertip to first knuckle crease) covers approximately one palm-sized area. Using more does not improve efficacy and increases the risk of side effects.
Daily use of potent topical corticosteroids should generally not exceed four continuous weeks without clinical review. Long-term management typically involves step-down to intermittent (twice weekly) use once active disease is controlled, combined with regular emollient use.
cream is water-based, absorbs quickly, and is suitable for moist, weeping, or infected-looking lesions. The ointment is oil-based, more occlusive, and better for dry, thickened, or scaly plaques; it is generally slightly more potent in practice due to enhanced penetration. The lotion is suitable for the scalp and hair-bearing areas.
