When to seek medical help

Threadworm infections are annoying but rarely serious.

However, you should see your doctor if:

• There is no improvement in symptoms, despite treatment

• The treatment has caused side effects

• There are new, or worsening symptoms

• There is a skin infection from scratching

• Your child is under 2 years old

• You are pregnant or breastfeeding

• If you suspect a rare worm infestation, such as roundworm, whipworm or hookworm
