Are Deworming Medicines Safe While Breastfeeding?

You may get a parasitic worm infection even when you are lactating. Receiving timely treatment is necessary for maintaining your health. Many factors may affect your treatment options, including the type of infection, your baby's age, and your overall health. However, most deworming medicines are considered safe even during breastfeeding.

Pregatips
Parasitic worm infections are uncommon in babies under one year of age. Seeing worms in your baby's stool or noticing symptoms such as persistent irritability or anal itching may indicate an underlying worm infection. Unlike older children, babies under one year are not routinely given deworming medicines. Such treatment is recommended only if it is confirmed or your paediatrician strongly suspects a worm infection. Considering your baby's age, weight, overall health, and the parasite causing the infection, they will recommend the safest treatment approach. Knowing whether deworming medicines are safe for your infant or if treatment should wait until they are older can help you make informed decisions.

Why Are Worm Infections Less Common in Babies Under One Year?

Babies younger than 12 months usually have a lower risk of intestinal worm infections because they have limited exposure to contaminated soil and food. However, infection is still possible.

It may happen because of:

  • Close association with an infected person with the baby
  • Poor hand hygiene among caregivers
  • Contaminated food or drinking water
  • Crawling on contaminated floors or outdoor surfaces
  • Living in areas where intestinal worm infections are common

Which Infections Are Possible In Babies?

Different parasites spread in different ways and may cause different symptoms.

Type of wormHow babies become infectedCommon symptoms
Threadworms (Pinworms)Contact with infected household members or contaminated surfacesNight-time irritability, anal itching, disturbed sleep
Roundworms (Ascariasis)Contaminated food, water or soilAbdominal swelling, vomiting, poor appetite
HookwormsContact with contaminated soil (rare in infants)Anaemia, tiredness, poor weight gain
TapewormsContaminated food (rare)Mild abdominal discomfort, poor growth
WhipwormsContaminated soilDiarrhoea, abdominal cramps, poor growth

When Might Your Baby Need Deworming Medicine?

Not every baby with digestive symptoms needs deworming medicine.

Your paediatrician may recommend treatment if:

  • Worms or worm segments are seen in the stool
  • The infection is confirmed through stool testing
  • Symptoms strongly suggest a parasitic infection
  • Your baby has been exposed to an infected household member, particularly with threadworms

Which Deworming Medicines Might Be Considered For Infants?

There are certain medicines that your paediatrician may consider for prescribing to your baby.

These are:

  • Albendazole
  • Mebendazole
  • Pyrantel pamoate
  • Praziquantel
Always consult a paediatrician before giving any deworming medicine to your baby.

Why Is Self-Medicating Your Baby Not Safe?

Many conditions can mimic a worm infection.

For example, symptoms such as itching, irritability, diarrhoea, or abdominal discomfort may also be caused by:

  • Nappy rash
  • Food allergies
  • Constipation
  • Anal fissures
  • Viral gastroenteritis
  • Bacterial infections
Therefore, giving such medicines to your baby without knowing the actual cause may be harmful. It may delay the correct diagnosis and expose your baby to medication unnecessarily.

What Side Effects May Happen With Deworming in Babies?

Most babies tolerate prescribed deworming medicines well.

However, some infants may experience mild, temporary side effects, including:

  • Nausea
  • Vomiting
  • Mild diarrhoea
  • Abdominal discomfort
  • Reduced appetite
Severe allergic reactions are uncommon but require immediate medical attention.

How Can You Help Prevent Worm Infections?

Simple hygiene measures can reduce your baby's risk of infection.

You can help by:

  • Washing your hands before feeding or handling your baby
  • Keeping your baby's fingernails short and clean
  • Cleaning frequently touched surfaces
  • Thoroughly washing fruits and vegetables before preparing baby food
  • Keeping crawling areas clean
  • Treating infected household members promptly if advised by your doctor

When Should You Consult Your Paediatrician?

Consult your doctor if your baby:

  • Has worms or worm segments in the stool
  • Develops persistent anal itching
  • Has ongoing diarrhoea
  • Vomits repeatedly
  • Has abdominal swelling
  • Is not gaining weight as expected
  • Has blood in the stool
  • Becomes unusually irritable without an obvious cause
Although deworming medicines may be prescribed for babies under one year in selected situations, they are not routinely recommended for all infants.
