You're standing in a pharmacy in Mexico City or maybe a clinic in Madrid, pointing at a red, itchy patch on your arm. Your brain scrambles. You need to know: how do you say rash in spanish? You might have learned a word in high school, but in the heat of the moment, it vanishes. Or worse, you use a word that makes the pharmacist look at you like you have three heads.
Spanish is localized. Regional.
Saying "rash" isn't just about one direct translation because medicine is specific. If it’s bumpy, that’s one thing. If it’s just a flat red patch, that’s another. Honestly, if you just walk in and say "tengo algo en la piel" (I have something on my skin), you'll get by, but you won't get the right cream. We need to get specific.
The Most Common Way to Say Rash in Spanish
The "textbook" answer to how do you say rash in spanish is usually erupción. It sounds like eruption. It’s formal. It’s what a doctor writes on a clipboard. But if you’re talking to a friend or a pharmacist, you’ll probably hear sarpullido.
Sarpullido is the king of everyday Spanish for rashes. It covers heat rash, hives, and that weird reaction you got from a new laundry detergent. It feels more natural. It’s the word a mom uses when her kid comes home from camp with itchy legs.
But wait. There is also eritema. This is a more clinical term, specifically referring to redness caused by increased blood flow in the capillaries. If you have a sunburn-like redness without bumps, a doctor might use this. Then there’s eccema, which is just the Spanish spelling for eczema. If your rash is chronic, dry, and scaly, that’s your word.
Regional Slang and Variations
Language isn't a monolith. It breathes. It changes based on whether you are in the Caribbean or the Andes.
In some parts of Latin America, particularly Mexico, you might hear people refer to a skin irritation as ronchas. Now, technically, ronchas are wheals or hives—those raised, itchy welts you get from an allergic reaction or a bug bite. If you tell a doctor "tengo ronchas," they are going to look for signs of an allergy, not necessarily a fungal infection or a heat rash.
In Puerto Rico or the Dominican Republic, you might hear tiricia used colloquially, though that sometimes drifts into meaning jaundice or a general feeling of malaise depending on the context. It’s confusing. Language is messy.
Why Context Is Everything
Imagine you’re at a consult. You can’t just say the word and stop. You need descriptors.
If the rash itches, you say it's picazón or comezón. In Mexico, comezón is the go-to. In Spain, they might lean toward picor.
"Me pica mucho" means "It itches a lot."
Simple. Effective.
Is it dry? Seco.
Is it oozing? Supurando. (That’s a gross one, but necessary for a diagnosis).
Is it painful? Doloroso.
If you go into a farmacia and say, "Tengo un sarpullido que me da mucha comezón," you have just successfully communicated that you have an itchy rash. You're 90% of the way to a solution.
Common Skin Conditions and Their Spanish Names
Sometimes the "rash" is actually something else entirely. If you're searching for how do you say rash in spanish, you might actually be looking for one of these specific ailments:
- Dermatitis de contacto: This is contact dermatitis. It happens when you touch something you're allergic to, like poison ivy or a harsh chemical.
- Culebrilla: This is the common name for shingles (Herpes Zoster). If your rash follows a nerve path and hurts like crazy, use this word. The formal term is herpes zóster, but everyone knows culebrilla.
- Psoriasis: Pronounced almost the same, just with a Spanish accent (pso-RYA-sis).
- Urticaria: The medical term for hives.
There’s a specific kind of rash called miliaria, which is heat rash. In many Spanish-speaking households, they just call it "sarpullido por calor." It’s those tiny red bumps babies get when it’s too humid. If you’re in a tropical climate, you’ll hear this constantly.
Talking to a Pharmacist or Doctor
Don't be afraid of sounding "incorrect." Medical Spanish is a bridge, not a test. Most healthcare providers in Spanish-speaking regions are used to different dialects.
However, precision helps. If you have a rash, tell them where it started.
"Empezó en el brazo" (It started on the arm).
"Se está extendiendo" (It is spreading).
If you need a topical treatment, you are looking for a crema or an ungüento (ointment). If it’s really bad, you might need an antihistamínico.

Interestingly, there’s a cultural element to skin care in many Spanish-speaking countries. You might be suggested a "remedio casero" (home remedy) like aloe vera—known as sábila. Sábila is the holy grail of skin care in Latin American households. Whether it's a burn, a rash, or a scrape, someone's abuela will suggest rubbing some fresh sábila on it. Honestly? It usually helps.
The Nuance of "Manchas"
Sometimes people use the word manchas to describe a rash. This is technically "spots" or "stains." If your rash is flat and looks more like discoloration than a breakout, manchas is the more accurate term.
"Tengo unas manchas rojas en la espalda" means "I have some red spots on my back."
This matters because sarpullido implies texture. Manchas implies color change. If you tell a dermatologist you have manchas but you actually have raised bumps, you're leading them down the wrong path.
Does the Cause Matter for the Translation?
Absolutely. If the rash is from a bug bite, it’s a picadura.
"Tengo una picadura que se puso fea" (I have a bite that turned ugly).
If it’s a fungal infection like athlete’s foot, it’s hongos (fungus).
You wouldn't usually call athlete's foot a sarpullido. You'd just say, "Tengo hongos en los pies." Accuracy saves time. It saves money on the wrong medicine.
Helpful Phrases for Your Visit
- ¿Qué me recomienda para este sarpullido? (What do you recommend for this rash?)
- ¿Es contagioso? (Is it contagious?)
- Necesito algo para la picazón. (I need something for the itching.)
- ¿Tiene receta médica? (This is what they will ask you: Do you have a prescription?)
- Es una reacción alérgica. (It's an allergic reaction.)
If you are in a pinch and can't remember any of this, just remember the word piel (skin). Everything starts there. "Problema de piel" is a universal "help me" signal in any pharmacy from Madrid to Buenos Aires.
Essential Next Steps for Managing a Rash Abroad
When dealing with a skin issue in a foreign country, getting the translation right is just the first hurdle. Once you've identified that you have a sarpullido or ronchas, you need to act.
First, document the progression. Take a photo of the area. This is vital if the rash changes or disappears before you get to a specialist. Spanish doctors, much like those in the US or UK, will want to know if the "brote" (outbreak) was sudden or gradual.
Second, check for systemic symptoms. If your "sarpullido" is accompanied by fiebre (fever) or dificultad para respirar (difficulty breathing), stop looking for translations and find an urgencias (emergency room) immediately. An allergic reaction that affects breathing is "anafilaxia," and it's a universal emergency.
Third, look for a "Farmacia de Guardia." In Spain and many Latin American countries, pharmacies rotate being open 24/7. Even if it's 3 AM, there is always a "pharmacy on duty" nearby. Look for the glowing green cross.
Finally, be wary of over-the-counter steroids. In some countries, you can buy strong steroid creams like Clobetasol without a prescription. While they clear up a rash fast, they can thin the skin or worsen fungal infections if used incorrectly. Always ask: "¿Es un corticoide?" (Is it a corticosteroid?) and use it sparingly until you see a professional.
If the rash persists for more than three days or starts to blister (ampollas), seek a consultation with a dermatólogo. Most private clinics in major Spanish-speaking cities offer "citas" (appointments) fairly quickly compared to public systems. Keep your insurance info and passport handy, as you'll likely need them for registration.
