Diprogenta is a Spanish betamethasone gentamicin cream. It mixes a strong steroid that calms inflamed skin with an antibiotic that treats a bacterial infection on top. Doctors use it for short courses on eczema or dermatitis that has also become infected. It is prescription-only in Spain. It must not be used on fungal rashes, which it can make worse.

TL;DR

Diprogenta contains betamethasone (a potent steroid) and gentamicin (an antibiotic).
It is for inflamed skin that is also infected with bacteria, not for plain eczema or plain infection.
Not for fungal or viral rashes, rosacea or the face. Not for children under 12 unless a doctor decides.
Prescription-only in Spain. Short courses only: long use thins the skin and breeds resistant bacteria.

When do doctors prescribe Diprogenta?

Its official use is inflamed skin conditions that respond to steroids, when bacteria have caused an infection on top. In practice that means:

Infected eczema: a red, itchy patch that has started to weep, crust or ooze.
Contact dermatitis that has been scratched open and become infected.
Inflamed, infected insect bites on a small area, when a doctor judges a cream is enough.

The steroid calms the redness, swelling and itch. The antibiotic deals with the bacteria. Diprogenta comes only as a cream in Spain.

Is there a UK or US version of Diprogenta?

Name	What it contains	Where
Diprogenta	Betamethasone dipropionate + gentamicin cream	Spain (prescription)
Fucibet	Betamethasone + fusidic acid	Spain and UK (prescription)
Betamethasone/Neomycin cream	Betamethasone + neomycin, a related antibiotic	UK (prescription)
Lotrisone	Betamethasone + clotrimazole, an antifungal	US: not the same thing

So a steroid-plus-antibiotic cream from home may have a different antibiotic in it. Do not swap a steroid-antifungal cream for Diprogenta, or the other way round. They treat different problems. A doctor may also choose Fucibet instead. Our Fucidine and Fucibet guide explains it.

Can you get Diprogenta without a prescription in Spain?

No. Every Diprogenta pack in Spain is listed as a medicamento sujeto a prescripción médica. That covers the Spanish packs and the imported ones sold here. The pharmacist needs a Spanish prescription; a private electronic one is valid. The AEMPS CIMA database shows the status of each pack.

The rule exists for a reason. A strong steroid on the wrong rash, such as a fungus, can hide it and help it spread. That is why a doctor should see the skin before you start.

Eczema that has flared, cracked and started to weep?

You can book a video visit with a GP licensed in Spain, in English or Spanish. He looks at the skin and tells you whether a steroid, an antibiotic, both or neither is right.

When is Diprogenta the wrong cream?

Fungal rashes: ringworm, athlete's foot, jock itch or yeast in skin folds. The steroid can make them spread.
Viral rashes: cold sores, chickenpox and shingles.
Rosacea and the red rash around the mouth (perioral dermatitis). Steroids make both worse.
Acne: strong steroids can cause spots.
Plain eczema with no infection. It needs moisturisers and, if prescribed, a steroid cream alone.
Deep wounds, ulcers or cellulitis: these need in-person care.

If you are not sure what a rash is, our eczema page and rash page describe what a doctor looks for.

Why is Diprogenta only for short courses?

Both parts of the cream cause trouble when used too long.

The steroid is potent. Over weeks it can thin the skin, cause stretch marks and change skin colour. More gets into the body on large areas, under dressings and in children.
The antibiotic: bacteria are becoming resistant to gentamicin. Long use can also let fungi grow.
The leaflet says a course should not go beyond two weeks. If the skin is not better, the doctor should look again.
It is not a cream to keep "for any red patch", and not for long-term eczema control.

Where should you not apply it?

Apply a thin layer to the affected area only, as prescribed. Wash your hands after.
Do not use it on the face, in skin folds such as the groin or armpits, or near the eyes and mouth.
Do not cover it with tight or plastic dressings unless your doctor says so.
It is not for babies under one. It is not advised under 12, as children absorb more steroid.
Pregnancy: as a rule it is not used in the first three months. Later, only if the doctor decides. If you breastfeed, never apply it to the breast.

Which side effects need a doctor?

On a short course, most people notice nothing. The gentamicin can cause brief redness or itch. The steroid can cause burning, dry or thin skin, colour change and small spots, mostly with long use. Contact a doctor when:

After a few days the patch is no better, or it is worse.
New spots appear at the edge, or the rash starts to look like a ring.
The skin around it turns hot, swollen and sore, or red lines appear.
Your sight becomes blurred.
You start to run a fever.

Call 112 if your face, lips or throat swell, you struggle to breathe, or redness spreads fast with a high fever.

Getting the skin checked by video

Dr. Yelamo is a GP licensed in Spain. He sees adults, children and pregnant patients by video, every day from 07:30 to 20:30 (Spain time). In the visit he will:

Ask you to show the patch on camera, close up and in daylight.
Check for signs of a fungus, a virus or rosacea, where a steroid cream would do harm.
Decide between a plain steroid, a steroid with an antibiotic, an antibiotic alone, or tablets.
Say how many days to use it, and what should happen if it does not settle.
Arrange an in-person check or a skin swab when the camera is not enough.

He does not promise any test or prescription before the visit. Where clinically appropriate, following a genuine evaluation. Treatment and prescriptions are issued solely at the doctor's discretion based on evidence-based clinical guidelines.

A prescription is never guaranteed: it is issued only where clinically appropriate after a genuine evaluation, as a private electronic prescription under Spanish law. This service is for urgent, non-emergency care. In an emergency, call 112.

See how the Urgent Care video visit works. It lasts 15 minutes and costs €50.

Frequently asked questions

What is Diprogenta?

A Spanish cream that combines betamethasone, a strong steroid, with gentamicin, an antibiotic. It is for inflamed skin, such as eczema, that has also become infected.

Can I buy betamethasone gentamicin cream without a prescription in Spain?

No. Diprogenta is prescription-only in Spain. A pharmacy needs a Spanish prescription, including a private electronic one.

Does Diprogenta work on fungal infections?

No. It must not be used on fungal rashes such as ringworm, athlete's foot or yeast in skin folds. The steroid can make them spread.

Can I put Diprogenta on my face?

The leaflet says not to. Facial skin is thin and reacts badly to strong steroids. A doctor will choose a different treatment for the face.

How long can I use Diprogenta?

Only for the short course your doctor sets. The leaflet says treatment should not go beyond two weeks. If the skin is not better, the diagnosis needs a second look.

Diprogenta or Fucibet: what is the difference?

Both mix betamethasone with an antibiotic. Diprogenta uses gentamicin, Fucibet uses fusidic acid. A doctor picks one based on the infection and what you used before.
