Topical mild steroid + antifungal Pregnancy: Limited data in pregnancy; animal studies with clotrimazole and corticosteroids have shown reproductive toxicity, but harmful effects are not predicted at the low systemic exposures following topical treatment. Can be used during pregnancy, but only under the supervision of a physician or midwife; as a precaution, prolonged application during pregnancy should preferably be avoided. Breast-feeding: a risk to the suckling child cannot be excluded — decide whether to discontinue breast-feeding or the product

Hydrocortisone with clotrimazole

Brand names: Canesten HC

Used in: Anaphylaxis & Allergy

This is a combination cream of the mild corticosteroid hydrocortisone with the imidazole antifungal clotrimazole, used for inflamed fungal skin infections such as tinea and candidal intertrigo where there is associated itch and inflammation.

Auto-extracted from the source labelling — not yet independently clinician-verified. These values were distilled from the UK SPC (or the US label where noted) but have not had a clinician sign-off. Confirm against the current SmPC before prescribing.

Adult dose

Dose: Apply thinly and evenly to the affected area and rub in gently
Route: Topical (cream)
Frequency: Twice daily
Max: A total daily dose of 10 mg cream per kg body weight should not be exceeded — for an adult weighing 50 kg the maximum daily dose is 500 mg cream, which equals approximately 2 cm of cream divided into 2 applications per day
Source: UK SPC for Canesten HC Cream (clotrimazole with hydrocortisone acetate), §4.2. Treatment should be for a maximum of 7 days. The SPC states there is no separate dosage schedule for the elderly or the young; however, long-term therapy to extensive areas of skin should be avoided, particularly in infants and children. Treatment duration: if acute symptoms have subsided after about 7 days but treatment is still required, this may be carried out with the corticoid-free preparation intended for this purpose. §4.4 adds that, because of the corticosteroid content, it should not be applied to large areas (more than 5–10% of the body surface), in long-term continuous therapy, or under occlusive dressings (such as nappies and bandages) — these restrictions apply particularly in infants (where the nappy can act as an occlusive dressing and increase systemic absorption) and in infants and children (where increased systemic absorption may occur, resulting in adrenocortical suppression).

Contraindications

  • Hypersensitivity to the active substances or to any of the excipients
  • Use on broken skin
  • Diseases affecting the skin (e.g. acne, rosacea, perioral dermatitis, lues, tuberculosis)
  • Any untreated bacterial skin diseases
  • Viral skin diseases (e.g. herpes simplex, chicken pox, shingles)
  • Dermal vaccination reactions

Side effects

  • Allergic reaction (syncope, hypotension, dyspnoea, urticaria)
  • Local skin reactions — blisters, discomfort/pain, oedema, erythema, irritation
  • Peeling/exfoliation, pruritus, rash, stinging/burning
  • Blurred vision
  • After use on large areas (>10% body surface) and/or long-term use (>2–4 weeks) or under occlusive dressings: skin atrophy, telangiectasia, hypertrichosis, striations, hypopigmentation, secondary infection and acneiform symptoms

Interactions

  • Latex contraceptives — laboratory tests have suggested that, when used together, this product may cause damage to latex contraceptives, so their effectiveness may be reduced (not reflected in clinical practice to date)

Clinical monograph

How it works

Hydrocortisone suppresses local inflammation through glucocorticoid receptor activation, while clotrimazole inhibits fungal ergosterol synthesis, disrupting the fungal cell membrane.

Prescribing in practice

  • The steroid component can mask and worsen untreated fungal infection if used alone or too long, so limit to short-term use for the inflammatory phase and continue antifungal cover until the infection clears.
  • It is not a substitute for a plain antifungal in non-inflamed tinea.
  • Avoid prolonged application to the face and flexures because of steroid-induced atrophy.

Monitoring

Review after a short course; once inflammation settles, consider switching to a plain antifungal until mycological cure.

Counselling the patient

  • Apply a thin layer to the affected area as directed and continue until advised to stop.
  • Do not use this combination long term or on undiagnosed rashes.
  • Keep the skin dry and avoid sharing towels to prevent spread.

Evidence & guidelines

Short-term combined steroid-antifungal use for inflamed dermatophyte infection reflects established dermatology prescribing practice.
