Sudocrem for a bum rash: what to know

Buttock irritation can follow sweat, prolonged moisture, rubbing, tight clothing, stool or urine contact, shaving, or a new product. [Intertrigo](/conditions/intertrigo/) affects skin folds and may become sore or moist. A rash with a ring-like edge may suggest [Ringworm](/conditions/ringworm/), while intense night itch or affected household contacts can point toward [Scabies](/conditions/scabies/). These patterns need different care.

Rinse gently, pat dry, and change damp clothing or underwear. Wear loose, breathable fabric and take breaks from prolonged sitting when possible. A thin layer of Sudocrem on clean, dry, intact skin may reduce contact with moisture and rubbing; stop if it stings or worsens the rash. Avoid applying it deep into broken skin or over a suspected fungal rash without advice. Do not scratch, because broken skin can become infected.

Arrange medical advice if the rash is spreading, recurrent, very painful, cracked, oozing, or not improving after basic skin care. Prompt assessment is needed for fever, rapidly increasing redness, pus, or severe tenderness. A clinician can distinguish irritation from [Contact Dermatitis](/conditions/contact-dermatitis/), psoriasis, infection, or another cause and recommend the right treatment.

Is moisture, friction, allergy, fungus, or another condition driving this rash? Should I use a barrier, antifungal, or anti-inflammatory treatment? How should I care for cracked or weeping skin?
