Betamethasone cream: what it treats, how to take it, side effects
Last updated September 3, 2026.
Betamethasone dipropionate cream is a medium-potency prescription corticosteroid for inflamed, itchy skin. It sits in the middle of the steroid strength ladder: stronger than hydrocortisone and desonide, milder than the super-potent agents, and approved for patients 13 and older.
What does it treat?
It relieves the inflammatory and itching symptoms of corticosteroid-responsive dermatoses: eczema, contact dermatitis, psoriasis, and similar rashes in patients 13 years and older. It quiets a flare over days to weeks. It does not fix the underlying condition, which is why rashes often return when it stops.
How do you take it?
Apply a thin film to the affected skin once or twice daily, rubbing it in gently, and wash your hands after. Use only enough to cover the rash. Do not wrap or bandage the area unless your doctor directs it, and do not use it on a child's diaper area under tight diapers or plastic pants. Treatment stops when control is achieved; if there is no improvement within 2 weeks, call your doctor instead of continuing. Missed dose: apply when remembered unless the next dose is near, and never apply a double layer.
Side effects to know
- Common: burning, itching, irritation, dryness, and redness where applied.
- Serious: skin thinning, stretch marks, and spider veins with prolonged use; absorption high enough to affect the body's cortisol system when used over large areas or under wraps; and worsening of untreated skin infections.
Who should not take it?
Do not use it if you are hypersensitive to betamethasone, other corticosteroids, or any ingredient in the cream. It is not for children under 13. Avoid the face, groin, and armpits unless your doctor directs it, and never apply it to untreated fungal, viral, or bacterial skin infections. Pregnant or breastfeeding patients should use it only on medical advice.
When is it an emergency?
Call 911 for signs of a severe allergic reaction: swelling of the face, lips, or throat, or trouble breathing. A rash that spreads fast with fever, severe pain, or pus needs same-day care.

Common questions
Where does betamethasone dipropionate sit on the steroid strength scale?
This cream formulation is labeled as medium potency: clearly stronger than over-the-counter hydrocortisone, below the high-potency and super-potent classes. That makes it a common first prescription for body rashes that hydrocortisone cannot clear.
Can I use betamethasone cream on my face or groin?
Not unless your doctor specifically directs it. Skin on the face, groin, and armpits is thin and absorbs much more steroid, which raises the risk of thinning and other local damage. Those areas usually get a low-potency agent instead.
Why is it not for children under 13?
The labeling for this cream limits it to patients 13 and older. Younger children absorb more steroid per pound through their skin and are more vulnerable to effects on their growth-related hormone systems, so pediatric rashes get agents studied in that age group.
How long can I use betamethasone cream?
Use it until the rash is controlled, then stop. If 2 weeks pass without improvement, the answer is a call to your doctor, not more cream. Repeated long courses on the same patch of skin invite thinning and stretch marks.
Is betamethasone the same as the steroid pills or shots?
Same family, very different exposure. The cream works mostly where you put it, with little reaching the bloodstream when used correctly on small areas. Oral or injected betamethasone affects the whole body and carries the systemic steroid risks people usually worry about.
What happens if I use it on athlete's foot or ringworm?
The steroid can briefly reduce redness and itching while the fungus keeps growing, then the infection comes back angrier and harder to recognize. Fungal rashes need an antifungal, alone or in a supervised combination, not a plain steroid.
