PUPPP Rash Checker
A few private questions to see whether your itchy pregnancy rash fits the pattern of PUPPP (also called PEP) — the benign, intensely itchy rash that classically starts in the belly stretch marks, spares the navel, and spreads to the thighs and buttocks late in a first pregnancy. It's educational, not a diagnosis, and everything you enter is read on your own device.
PUPPP is benign and clears after birth — but this is a pattern check, not a diagnosis, and itching without a rash points somewhere else.
PUPPP rash checker
This is not for an emergency. If you have a fever with a rash, blistering, a rash spreading fast — or you're itchy without a rash — don't fill in a checker: contact your provider.
This is a pattern check against published descriptions of PUPPP (ACOG; American Academy of Dermatology; MedlinePlus) — it is general information, not a diagnosis. PUPPP is confirmed by a clinician who looks at your skin, and a couple of look-alike conditions need medical evaluation, so every result points you back to a provider.
How they're told apart
Itchy in pregnancy? What tells these apart
Several pregnancy conditions itch, and they can feel alike — but the plan is very different. The single most useful question is whether there's a rash you can see: PUPPP is a rash; the condition that most needs ruling out, cholestasis, is itching with little or no rash. Here's the short version.
| Condition | The tell-tale clue | What to do |
|---|---|---|
| PUPPP / PEP | Itchy bumps and hive-like patches that begin in belly stretch marks, usually spare the navel, and spread to thighs/buttocks; late pregnancy, often a first pregnancy. | Benign and clears after birth. Have it confirmed by your OB or a dermatologist, who can prescribe anti-itch treatment. |
| Cholestasis (ICP) | Intense itching with little or no rash, classically worst on the palms and soles and often worse at night. | Not PUPPP. Needs a blood test and prompt evaluation because it can affect the baby — contact your provider and use the cholestasis checker. |
| Pemphigoid gestationis | An itchy rash that often starts around the belly button and may blister — not the usual PUPPP pattern. | A rarer autoimmune rash. See your OB and ask about a dermatology referral so it can be evaluated. |
| A rash with fever or feeling unwell | Any rash together with fever, chills, feeling generally ill, rapid spread, pain, or blisters over open skin. | These are reasons to be seen promptly, whatever the cause — contact your provider or seek care. |
Descriptions follow ACOG, the American Academy of Dermatology, and MedlinePlus. This table helps you have a sharper conversation — it doesn't replace the clinician who looks at your skin.
The one that isn't PUPPP
Itching without a rash? That's a different path
If you're intensely itchy but there's no rash to see — especially on the palms of your hands and the soles of your feet, and especially if it's worse at night — that pattern points away from PUPPP and toward intrahepatic cholestasis of pregnancy (ICP). Cholestasis is a liver-related condition that's diagnosed with a blood test, and because it can affect the baby, it needs prompt evaluation and monitoring rather than an anti-itch cream. MedlinePlus is explicit about this: persistent itching without a rash should be reported to your provider, as it may indicate cholestasis.
Itchy, but no rash?
This checker is for the PUPPP rash. If the itching is the whole story, use the cholestasis checker and contact your provider about a blood test.
Open the cholestasis checkerThe reassuring part
PUPPP is miserable to itch through — and harmless to the baby
Here's the genuinely good news about PUPPP: it is benign and self-limited. It does not harm the baby, and it goes away on its own after you give birth. The whole aim of treatment is comfort, not danger — clinicians commonly prescribe topical steroid creams and oral antihistamines, alongside simple soothing measures like cool showers, fragrance-free moisturizers, and loose cotton clothes, to make the weeks until delivery bearable.
Two honest caveats keep this from being a green light to self-diagnose. First, don't start a prescription cream or medication on your own in pregnancy — which product and dose are safe is your provider's call, so the itch is a reason to check in. Second, a few look-alike conditions aren't harmless: itching without a rash can be cholestasis, and a rash that blisters or starts at the navel can be something rarer that needs a dermatologist. That's why even a textbook-PUPPP pattern here ends the same way — have it confirmed, then treat the itch with a plan you made together.
Know these regardless
See a provider promptly if…
A pattern check describes a likely picture; these describe reasons not to wait. Whatever a checker says, if any of the following are true, contact your provider — these are the features that change the plan:
- Itching without a rash — especially on the palms or soles. This can be intrahepatic cholestasis of pregnancy (ICP), which needs a blood test.
- A rash that blisters, or one that starts at the belly button and spreads outward — this is not the usual PUPPP pattern.
- Fever, chills, or feeling generally unwell along with a rash.
- A rash that covers most of your body, spreads quickly, or is painful.

Where this comes from
The general picture of PUPPP — an itchy rash of bumps and patches that appears late in pregnancy (most often in the third trimester, after about 34 weeks), starts on the belly and spreads to the thighs, buttocks, and breasts, and clears after birth — and the note that treatment is soothing measures, topical steroids, and antihistamines, follow ACOG's patient guidance and MedlinePlus. MedlinePlus and ACOG also state directly that persistent itching without a rash should be reported to a provider, because it can signal cholestasis. The more specific distinguishing details this checker uses — that PUPPP characteristically begins within the belly stretch marks, tends to spare the skin right around the navel, and is most common in a first pregnancy — are the standard dermatology description of the condition rather than claims made in those two patient FAQs. The red-flag features (blistering, fever or illness with a rash, a rash that spreads fast or covers most of the body) follow the American Academy of Dermatology's guidance on when a rash needs medical attention. The checker maps your answers to these published descriptions and always ends at a clinician.

PUPPP & itchy pregnancy rashes: frequently asked questions
What PUPPP is, why itching without a rash is different, whether it's dangerous for the baby, how it's treated, when to call, and how private this is.
What is PUPPP (PEP)?
PUPPP stands for pruritic urticarial papules and plaques of pregnancy; outside the U.S. it's usually called polymorphic eruption of pregnancy, or PEP. It's the most common of the pregnancy-specific rashes, and it's benign: small, intensely itchy red bumps and hive-like patches that classically begin inside the stretch marks on the belly, often spare the skin right around the navel, and can spread to the thighs, buttocks, arms, and breasts. It usually shows up late — in the third trimester, most often after 34 weeks, and typically in a first pregnancy. The important word is benign: PUPPP does not harm the baby, and it clears up after you give birth. What it does do is itch, sometimes miserably — which is where treatment comes in.
How is the difference between PUPPP and cholestasis so important?
Because they're managed completely differently, and this tool will always separate them. PUPPP is a rash you can see and feel — bumps and patches. Intrahepatic cholestasis of pregnancy (ICP) is the opposite: intense itching with little or no rash, classically worst on the palms of the hands and the soles of the feet, often worse at night. That distinction matters because cholestasis is a liver-related condition diagnosed with a blood test, and it can raise the risk of problems for the baby, so it needs prompt medical evaluation and monitoring. A benign itchy rash and a condition that needs blood tests can feel similar to the person itching — so if you're itchy without a rash, this checker routes you to the cholestasis checker and to your provider rather than reassuring you.
Is PUPPP dangerous for my baby?
No. PUPPP is considered harmless to the baby — it's an uncomfortable skin condition, not a threat to the pregnancy, and it resolves after delivery. That's the single most reassuring fact about it, and it's why the main job of care is controlling the itch rather than protecting the baby from the rash. The caution is only this: several itchy pregnancy conditions can look alike at a glance, and a couple of them — cholestasis, and rarer autoimmune rashes like pemphigoid gestationis — are not harmless and do need medical attention. So the safe move is to have the rash actually looked at by your OB or a dermatologist, who can confirm it's PUPPP and rule the others out.
How is PUPPP treated?
The goal is relief, because the rash itself will clear after birth. Clinicians commonly recommend soothing measures and prescribe topical steroid creams to calm the inflammation, along with oral antihistamines to take the edge off the itch; stubborn cases are occasionally treated with a short course of oral steroids. Simple comfort steps — cool showers, fragrance-free moisturizers and anti-itch lotions, loose cotton clothing — help in the meantime. The one rule this tool won't bend on: don't start a prescription cream or a medication on your own in pregnancy. Which steroid, which antihistamine, and what's safe at your stage are your provider's calls, so the itch is a reason to check in, not to self-treat.
When should I call my provider instead of using a checker?
Call rather than click if any of these are true: you're itchy but don't see a rash (especially on the palms or soles), because that points toward cholestasis and needs a blood test; the rash is blistering, or it started right at your belly button and spread outward, which isn't the usual PUPPP pattern and can signal a different condition; you have a fever or feel generally unwell with the rash; or the rash covers most of your body, is spreading fast, or is painful. Those features are the reason a symptom checker can never replace a clinician — they change the plan. This tool flags them for you and points you to your provider; it doesn't try to manage them.
Is what I enter here private?
Yes. This checker runs entirely in your browser: the answers you give are interpreted on your own device and are never sent to a server, saved, or shared — close the tab and they're gone. There's no account, no tracking of your answers, and nothing to delete, because nothing is stored. What you get back is general educational information based on published guidance from ACOG, the American Academy of Dermatology, and MedlinePlus — it isn't medical advice, a diagnosis, or a substitute for the clinician who can actually look at your skin.
