Safe Topical Medications and Creams During Pregnancy: What You Can and Can’t Use

Safe Topical Medications and Creams During Pregnancy: What You Can and Can’t Use

When you’re pregnant, even the smallest skin irritation can feel like a big problem. Eczema flares up. Acne breaks out. Fungal infections creep in. You want relief-but you’re terrified of harming your baby. The good news? Most topical medications are much safer than you think. Unlike pills or injections, creams and lotions barely make it into your bloodstream. But not all of them are safe. Some can still pose risks, especially if used wrong or in the wrong trimester.

Why Topical Medications Are Usually Safer in Pregnancy

Topical treatments work on the skin’s surface. Only a tiny fraction-usually 1% to 10%-gets absorbed into your blood. That’s why they’re often the first choice for treating rashes, acne, or fungal infections during pregnancy. Compare that to oral antibiotics or retinoids, which flood your system and can cross the placenta easily. A 2016 review in the Journal of Drugs in Dermatology found that most topical dermatologic drugs have minimal fetal risk because of this low absorption rate.

But here’s the catch: absorption isn’t the same everywhere. Skin on your face, neck, armpits, and groin absorbs more than skin on your forearm or leg. So applying a strong steroid cream to your eyelids? That’s riskier than using it on your arm. Always apply the smallest amount needed, and avoid covering large areas for long periods.

What’s Safe for Acne During Pregnancy

Acne is super common during pregnancy-hormones go wild, oil glands go into overdrive. You might be tempted to reach for your old acne cream, but many popular ones are off-limits.

Safe options:
  • Benzoyl peroxide (5-10%): This is one of the most recommended treatments. It kills bacteria and unclogs pores. Studies show less than 5% gets absorbed, and no birth defects have been linked to its use.
  • Topical clindamycin: An antibiotic that works well for inflammatory acne. About 4-5% is absorbed, but serum levels stay too low to cause concern. Often combined with benzoyl peroxide for better results.
  • Topical erythromycin: Another antibiotic option with a strong safety record in pregnancy. Used for years without evidence of fetal harm.
  • Azelaic acid (15-20%): Great for acne and melasma (the pregnancy mask). Classified as Category B, and many women report clear skin with no side effects.
What to avoid:
  • Topical retinoids (tretinoin, adapalene, tazarotene): Even though they’re applied to the skin, case reports link them to birth defects when used in early pregnancy. The American College of Obstetricians and Gynecologists (ACOG) says to stop them before trying to conceive.
  • Salicylic acid in high doses or large areas: Low concentrations (2% or less) in cleansers or toners are generally fine. But avoid peels, masks, or spot treatments with higher concentrations-especially in the third trimester.

Managing Eczema and Itchy Skin

Itchy, red, flaky skin? You’re not alone. About 20% of pregnant women develop eczema or pregnancy-related rashes like PUPPP. The key is gentle, targeted treatment.

Safe choices:
  • Low-potency hydrocortisone cream (1%): This is the go-to for mild eczema. Used sparingly on small areas, it’s considered safe. Studies show no increased risk of low birth weight or cleft palate.
  • Mild to moderate corticosteroids (like desonide): These are fine for short-term use under your doctor’s guidance. Avoid potent versions (like clobetasol) unless absolutely necessary.
  • Moisturizers with ceramides: These aren’t drugs, but they’re essential. Keeping skin hydrated reduces flare-ups and the need for steroids.
What to skip:
  • High-potency steroids (clobetasol, betamethasone): These can cross the placenta in small amounts. Long-term or widespread use has been linked to lower birth weight in rare cases.
  • Calcineurin inhibitors (tacrolimus, pimecrolimus): These are not well studied in pregnancy. Most doctors recommend avoiding them unless you’ve tried everything else.

Fungal Infections: Yeast, Athlete’s Foot, Ringworm

Pregnancy increases your risk of yeast infections-up to 30% of women get one. Vaginal itching, white discharge? You need treatment. But not all antifungals are created equal.

Safe first-line options:
  • Clotrimazole (cream, suppository): First choice for vaginal yeast infections. Used for decades with no evidence of harm.
  • Miconazole: Same safety profile. Available as creams for skin and vaginal suppositories.
  • Nystatin: Often used for oral thrush or diaper rash. Not absorbed systemically, so it’s very safe.
Use with caution or avoid:
  • Econazole: Avoid in the first trimester. Use only if needed in later months, and only on small areas.
  • Terbinafine (Lamisil): Not well studied. Skip it unless your doctor says it’s necessary.
  • Ketoconazole: Newer data from 2022 suggests short-term topical use is acceptable, but still avoid oral versions entirely.

What About Pain and Inflammation?

Back pain? Swollen ankles? You might reach for a topical NSAID like diclofenac gel. It sounds harmless-just rub it on. But it’s not risk-free.

Safe? Sort of. Topical NSAIDs absorb less than pills, but they still enter your bloodstream. The American Academy of Family Physicians warns: avoid them after 30 weeks. Why? They can cause the ductus arteriosus-a vital blood vessel in the baby’s heart-to close too early. This can lead to serious heart problems.

Best alternative: Use acetaminophen (Tylenol) for pain. It’s the safest oral option in pregnancy. For localized pain, try cold packs, gentle massage, or pregnancy support belts.

Antiviral Creams for Cold Sores and Herpes

If you have a history of cold sores, pregnancy can trigger outbreaks. The good news? Topical antivirals are mostly safe.

Safe options:
  • Acyclovir cream: Used for herpes simplex (cold sores). Minimal absorption. Studies show no increased risk of birth defects.
  • Trichloroacetic acid: Used for warts. Safe in pregnancy when applied by a professional.
What to avoid:
  • Podofilox and podophyllin resin: These are used for genital warts but can be toxic to the fetus. Never use them during pregnancy.

What About OTC Products and Natural Remedies?

Just because something’s “natural” doesn’t mean it’s safe. Tea tree oil? Aloe vera? Witch hazel?

  • Aloe vera gel: Safe for minor burns or rashes. Avoid oral aloe.
  • Tea tree oil: Diluted topical use (1-5%) is generally fine for acne or fungal spots. Don’t use undiluted or near the eyes.
  • Witch hazel: Safe for hemorrhoids or irritated skin. No systemic absorption.
  • Essential oils: Skip them unless approved by your OB. Many (like rosemary, basil, cinnamon) can stimulate contractions or affect hormones.
And watch out for hidden ingredients. Some “natural” creams contain salicylates, retinoids, or hydroquinone. Always read the label.

When to Call Your Doctor

You don’t need to panic over every little rash. But call your OB or dermatologist if:

  • A rash spreads quickly or looks infected (red, warm, oozing)
  • You used a cream you weren’t supposed to-especially retinoids or strong steroids
  • You’re using any topical medication for more than two weeks without improvement
  • You have severe itching all over your body, especially at night (could be cholestasis of pregnancy)
The InfantRisk Center handles over 1,200 pregnancy-related medication questions every month. They’re a trusted resource for doctors and patients alike. If you’re unsure, call them or ask your provider to check.

Key Takeaways: What to Remember

  • Topical meds are usually safer than pills-but not all are safe.
  • Avoid topical retinoids (tretinoin, adapalene) completely during pregnancy.
  • Benzoyl peroxide, clindamycin, azelaic acid, and low-dose hydrocortisone are safe for acne and eczema.
  • Clotrimazole and miconazole are best for yeast infections.
  • Avoid topical NSAIDs after 30 weeks.
  • Read labels. Many OTC products contain hidden risky ingredients.
  • When in doubt, ask your doctor or pharmacist. Don’t guess.

Most women who use approved topical treatments during pregnancy have healthy babies. The goal isn’t to avoid all medications-it’s to use the right ones, the right way, at the right time.

Is hydrocortisone cream safe during pregnancy?

Yes, low-potency hydrocortisone cream (1%) is considered safe for short-term use on small areas during pregnancy. It’s commonly used for eczema, bug bites, and mild rashes. Avoid using it on large areas or for long periods, and never apply it to the breasts before nursing. Stronger steroids (like clobetasol) should only be used under medical supervision.

Can I use acne cream with benzoyl peroxide while pregnant?

Yes, benzoyl peroxide is one of the safest acne treatments during pregnancy. Only a small amount (under 5%) is absorbed into the bloodstream, and no birth defects have been linked to its use. It’s often recommended as a first-line treatment for pregnancy acne. Use it as directed-usually once or twice daily-and avoid combining it with other harsh products.

Are topical retinoids dangerous during pregnancy?

Yes. Topical retinoids like tretinoin, adapalene, and tazarotene should be avoided during pregnancy. Even though they’re applied to the skin, case reports link them to rare birth defects when used in early pregnancy. The American College of Obstetricians and Gynecologists recommends stopping them before trying to conceive. If you used one before realizing you were pregnant, don’t panic-most women in these cases have healthy babies-but tell your doctor right away.

Can I use antifungal cream for a yeast infection while pregnant?

Yes, clotrimazole and miconazole are the preferred antifungal treatments for vaginal yeast infections during pregnancy. They’re available as creams, suppositories, or tablets and have been used safely for decades. Nystatin is also safe and often used for oral thrush. Avoid econazole in the first trimester and use it only if needed later in pregnancy.

Is it safe to use topical NSAIDs like diclofenac gel when pregnant?

Use with caution. Topical NSAIDs like diclofenac gel are absorbed in small amounts and may be safe before 30 weeks. But after 30 weeks, they can cause the baby’s ductus arteriosus (a heart blood vessel) to close too early, leading to serious complications. The American Academy of Family Physicians advises avoiding them in the third trimester. For pain, acetaminophen and physical therapies are safer choices.

What should I do if I accidentally used a risky cream during early pregnancy?

Don’t panic. Most topical medications have very low absorption, and many women who accidentally use a risky cream still have healthy babies. Stop using the product immediately and contact your doctor or midwife. They can assess the specific medication, how much you used, and when you used it. In most cases, no further action is needed, but your provider may recommend extra monitoring. The InfantRisk Center (1-800-822-2336) also offers free expert advice for pregnancy medication concerns.
