Nail Fungus During Pregnancy – 2026

Pregnancy is an exciting time, but it also brings many changes to your body. Along with changes in your skin and hair, you may notice changes in your nails. If a toenail starts turning yellow, becoming thick, or looking brittle, you may wonder if it’s nail fungus and whether it’s safe to treat during pregnancy.

The good news is that nail fungus is usually not harmful to your baby. However, treatment during pregnancy requires extra care because some antifungal medicines are not considered safe for pregnant women. Here’s everything you need to know.

What Is Nail Fungus?

Nail fungus, also called onychomycosis, is a common fungal infection that affects the fingernails or toenails. It develops slowly and is much more common in toenails because fungi thrive in warm, moist environments.

Common symptoms include:

• Yellow, white, or brown nail discoloration
• Thickened nails
• Brittle or crumbly edges
• Nails lifting away from the nail bed
• Debris under the nail
• Mild odor in advanced cases

Why Can Nail Fungus Develop During Pregnancy?

Pregnancy doesn’t directly cause nail fungus, but it can create conditions that make fungal infections more likely.

Some reasons include:

• Hormonal changes that affect nail growth
• Increased sweating around the feet
• Swollen feet that make shoes tighter
• Changes in the immune system
• Warm, moist conditions inside shoes

These factors allow fungi to grow more easily, especially if you already have athlete’s foot or damaged nails.

Is Nail Fungus Dangerous During Pregnancy?

For most women, the answer is no.

The infection usually stays inside the nail and does not spread to your baby. The biggest concern is choosing a treatment that is safe during pregnancy.

However, you should contact your healthcare provider if you notice:

• Severe pain
• Redness or swelling
• Pus around the nail
• Several infected nails
• Fever
• You have diabetes or poor circulation

How Doctors Diagnose Nail Fungus

Not every thick or yellow nail is caused by fungus. Psoriasis, eczema, injuries, and other nail conditions can look very similar.

Your doctor may recommend:

• A physical nail examination
• A nail scraping
• A fungal culture
• Microscopic testing of the nail sample

Getting the correct diagnosis helps avoid unnecessary treatment.

Safe Treatment Options During Pregnancy

Treatment depends on how severe the infection is.

Careful Monitoring

If the infection is mild and painless, your doctor may simply monitor it until after delivery.

Nail Trimming

Keeping the nail short and filing thick nails can improve comfort and help topical treatments reach the infected area more effectively.

Topical Treatments

Some topical antifungal medicines may be considered during pregnancy if your healthcare provider believes the benefits outweigh the risks.

Good Foot Care

Simple daily hygiene plays an important role in preventing the infection from becoming worse.

Treatments Usually Avoided

Doctors generally avoid oral antifungal medicines during pregnancy because they may pose risks to the developing baby.

Medicines commonly postponed include:

• Terbinafine tablets
• Itraconazole
• Fluconazole (unless specifically prescribed for another condition)

Never start these medications without medical advice.

Home Care Tips

You can support healthy nails by following a few simple habits:

• Wash your feet daily.
• Dry carefully between your toes.
• Wear breathable shoes.
• Change socks every day.
• Avoid sharing nail clippers.
• Wear flip-flops in public showers and swimming pools.
• Keep your nails trimmed straight across.

Can You Get a Pedicure While Pregnant?

Yes, but choose a clean salon that follows proper hygiene practices.

Look for:

• Sterilized nail tools
• Clean foot baths
• Fresh towels
• Licensed nail technicians

If possible, bring your own nail tools to reduce the risk of infection.
