Mometasone cream: what it treats, how to take it, side effects
Last updated September 3, 2026.
Mometasone furoate cream (brand name Elocon) is a medium-potency prescription corticosteroid applied just once a day. The once-daily schedule, plus approval down to age 2, makes it a practical choice for eczema in both adults and children.
What does it treat?
It relieves the inflammation and itching of corticosteroid-responsive skin conditions, most commonly atopic dermatitis (eczema) and psoriasis. In pediatric trials for atopic dermatitis, most patients cleared within about 3 weeks of once-daily use. It controls flares; the underlying tendency remains, so maintenance skincare still matters.
How do you take it?
Apply a thin film to the affected skin once daily, at about the same time every day, and wash your hands afterward. Once daily is the labeled schedule, so applying it more often adds side effects without adding benefit. Do not wrap or bandage the area, and do not use it on the face, underarms, or groin unless your physician directs it. Stop when the skin is controlled; if there is no improvement in 2 weeks, contact your doctor. Missed dose: apply when remembered unless the next dose is near.
Side effects to know
- Common: burning, itching, stinging, dryness, and mild skin irritation where applied.
- Serious: skin thinning and stretch marks with prolonged use, and measurable effects on the body's cortisol system in some patients, particularly children. In one pediatric study, the cream slightly lowered adrenal corticosteroid secretion. Untreated skin infections can worsen under cover of the steroid.
Who should not take it?
Do not use it if you are hypersensitive to any component. It is not recommended under age 2, and in children under 12 it should not be used in the diaper area, since diapers act like an occlusive dressing. Avoid untreated fungal, viral, or bacterial skin infections. Pregnancy and breastfeeding use should be decided with your doctor.
When is it an emergency?
Call 911 for swelling of the face, lips, or throat or trouble breathing after applying. A rapidly spreading rash with fever, severe pain, or pus needs same-day care. Pymander's escalation routing is built and tested specifically for this class of decision; see the safety architecture working paper.

Common questions
Why is mometasone only applied once a day?
Its formulation keeps working in the skin for a full 24 hours, so the label calls for one application daily. Applying it more often does not clear rashes faster; it only increases absorption and the risk of thinning. The once-daily schedule also makes it easier to stick with.
Is mometasone cream safe for toddlers?
It is approved for patients 2 years and older, which is unusual enough to matter: many steroids are not labeled for young children. Use the thinnest layer, once daily, for the shortest time that controls the flare, and keep it out of the diaper area, where a snug diaper acts like a wrap and boosts absorption.
How does mometasone compare to hydrocortisone?
Mometasone is a medium-potency prescription steroid, a clear step up from over-the-counter hydrocortisone. It clears flares that hydrocortisone cannot, but it also carries a bigger risk of skin thinning with overuse, so the 2-week checkpoint with your doctor matters.
Can I put mometasone on my child's face?
Only if the physician specifically directs it. The label says to avoid the face, underarms, and groin unless directed, because thin skin there absorbs more and thins more easily. Facial eczema in kids is usually handled with low-potency steroids or non-steroid creams.
Does mometasone affect a child's growth?
Systemic absorption is small with correct use, but pediatric studies have shown slight, measurable effects on the body's own cortisol production with once-daily use. That is why courses are kept short and reviewed, and why long continuous stretches without a doctor's oversight are not advised.
Should I moisturize while using mometasone?
Yes. Moisturizer is the daily backbone of eczema care, and the steroid is the flare treatment on top of it. A practical routine is steroid on the inflamed spots once daily and a thick fragrance-free moisturizer everywhere, at a different time of day or after the steroid has absorbed.
