Albendazole is an anthelmintics drug that kills or expels the worms from your intestine. 

You will be shocked to know that 64% of children were at risk from STH (Soil-Transmitted Helminths) in 2012. 

Worm infestation can spread to anyone, but it is more prevalent in children who live in a soil area or live in an unclean environment, eat without washing their hands, and play with pets like cats or dogs. 

Generally, all worms are known as parasitic worms. In medical terms, they are known as helminths. If you get a worm infection, it would say Helminthiasis.

Although Helminthiasis is rarely deadly, it frequently makes your health ill, especially in children. 

Albendazole Dose for Children

This article aims to provide an accurate albendazole dose for children in India.  

We will discuss how to take albendazole for deworming in kids like infants (1-2 years), toddlers/preschool (2-3 years), and school-aged children (more than 3 years).

Let’s know about this medicine.

What is National Deworming Day (NDD)? What medicine is given to children on NDD?

In India, soil-transmitted helminths (STH) are a significant threat to public health. An estimated 22 crore Indian children ages 1-14 are potentially at risk for worm infections.

The presence of worms in children can lead to anaemia, malnutrition, and impaired mental and physical development.

To address this problem, in 2015 Government of India launched a fixed date on 10th February every year for deworming for all children aged 1-19 years.

This date is considered National Deworming Day.

National Deworming Day is a public health initiative, which was aimed at reducing the burden of parasitic worm infections among children.

During this day, albendazole medicine is administered to children at school sites, Anganwadi centers, and many health centers to prevent the spread of parasitic worms.


What class of drug is albendazole?

Albendazole is a prescription medication used to treat infections caused by a type of worm called a helminth

This drug belongs to a group of medicines called anthelmintics. It is a broad-spectrum anthelmintic of the benzimidazole class that is designed to treat all worms.


What are the uses of albendazole? 

Since albendazole is a broad-spectrum anthelmintic, therefore it is an effective drug in various intestinal worms and systemic (or tissue) worm parasites. 

Intestinal helminths 

Certain parasitic worms may enter your body due to a poor hygienic environment. These parasitic worms live in your intestine. They grow gradually by absorbing nutrients and glucose from your body. As a result, these worms start multiplying themselves by producing eggs.

Here, Albendazole drug is used in the treatment of the following diseases – 

  • Roundworm disease (Ascariasis & Strongyloidiasis) – Roundworm grows in the small intestine. It may penetrate the blood and infect your lungs. This type of worm can be fatal in immunosuppressed patients.
  • Hookworm disease (ancylostomiasis and necatoriasis) – Hookworm lives in the small intestine of an infected person. It causes anemia via intestinal blood loss.
  • Pinworm or threadworm disease (Enterobiasis) – white worms can be seen in the stool.
  • Whipworm disease (Trichuriasis) – generally lives in the large intestine. 


Hookworm, roundworm, and whipworm are known as soil-transmitted helminths. 

Pinworm or threadworm is the most common parasite that causes infestation in kids.

Systemic helminths 

Worm infestation can be fatal if worms migrate into your blood and tissues. It can penetrate your tissue or blood via the intestine, skin, and respiration. 

Fortunately, albendazole is a highly effective drug, even in systemic helminths.

Albendazole can be used in certain diseases like – 

  • Filariasis – Worms cause blockage of your lymph flow. Due to this, your arms, legs, and scrotum may get filled with fluid. 
  • Trichinosis – Consumption of insufficiently cooked meat, especially pork, usually leads to this condition.
  • Cystic hydatid infection (Echinococcosis) – Caused by larvae of Dog tapeworm. It mainly affects your liver, lungs, and brain.
  • Neurocysticercosis – Caused by larvae of the pork tapeworm. It mainly affects your brain and spinal cord area.

How do you know if you have worms in your stomach?

You may have experienced the following symptoms of worms in the stomach or intestine – 

  • Abdominal pain
  • Nausea or vomiting 
  • Diarrhea
  • Small and white worms in stool
  • Severe itching around your anus, especially at night
  • Loss of weight 
  • Loss of appetite
  • Blood in stool
  • Fatigue


Sometimes, your child may do teeth grinding. During this condition, your child may also have an abnormal craving for eating inedible foods like chalk, clay, paper, ashes, etc. This eating disorder is called Pica


How can we use albendazole tablets or syrup in different parasitic infections?

Although albendazole 400 mg is considered the standard dose for children above 2 years in most worm infections like – 

  • Hookworm disease (ancylostomiasis and necatoriasis)
  • Roundworm infection (ascariasis)
  • Whipworm infection (trichuriasis)
  • Threadworm infection (strongyloidiasis) 
  • Pinworm infection (enterobiasis) 
  • Giardia infection (giardiasis in children)


However, the albendazole dose may vary in worm infections like Cystic hydatid disease and Neurocysticercosis. 

Larvae of dog tapeworm generally cause a cystic hydatid infection. It mainly affects your liver, lungs, and stomach.

Whereas larvae of the pork tapeworm cause neurocysticercosis infection. It mainly affects your brain and spinal cord area. 

Here, albendazole is considered a drug of choice in Cystic hydatid disease and Neurocysticercosis

The dosing of albendazole in these conditions is entirely different.

If you have cystic hydatid disease, you need to take albendazole 400 mg twice for 28 days in 3 cycles of treatment, followed by a 14-day washout period. 

The dose will be calculated for children as 15 mg/kg per body weight.

In Neurocysticercosis, albendazole 400 mg twice daily with meals for 8 to 30 days. It can be repeated as necessary.


Is Albendazole safe for toddlers (1-3 years old children)?

According to a study, Albendazole medicine is generally recommended as preventive chemotherapy (deworming) because children are more at risk of worm infection.

It is a highly effective and well-tolerated drug among children over 1 year. 

A review article published in Cambridge University Press 2001 summarised the safety and efficacy of Albendazole in humans. 

In this study, Albendazole was found safe in children and adults.

It has very low or negligible side effects. Moreover, Albendazole is easy to administer because this medicine requires only single-dose administration

However, Albendazole is the safest drug; nevertheless, it’s crucial to consult with a healthcare professional or paediatrician.

Albendazole syrup dose for 1 year old child

The albendazole dose is 15 mg/kg/day of body weight, which requires a single dose.

Suppose your child is 1 year old and his/her body weight is around 10 kg. To calculate albendazole dosage, we need to multiply 15 mg/kg by 10 kg. After calculating, your child will require 150 mg (15 x 10) albendazole drug.

The Albendazole 200 mg is considered the standard dose for 1 year old child. Your child will require 5 ml of albendazole syrup.


Albendazole syrup dose for 2 year old child

Suppose your child’s age is more than 2 years. In that case, you will be required to give an entire albendazole oral suspension bottle (400 mg of 10ml).

Should albendazole be taken before or after meals for deworming?

It depends on the type of worm infestation you have – 

For intestinal worms before the meal

Suppose you have intestinal worms. In this case, you should take the Albendazole drug on an empty stomach because you don’t require the medication inside your blood. 

If you take albendazole empty stomach, it will stay longer in your intestine and work effectively to kill parasitic worms. After one hour of taking medicine, you can have your meal.


For systemic worms after meals

If you have parasitic worms in your blood or tissue, such as dog tapeworms, pork tapeworms, etc., you will require albendazole medicine in your blood.

Generally, albendazole gets rapidly absorbed in your blood with fatty food. 

It is always better to take albendazole with a fatty meal (high-fat content) like milk, paneer, cheese, etc. The absorption of the albendazole drug increases five times more if you take albendazole with a fatty meal. 


What to do if pinworms keep coming back?

Suppose your kids are not getting a response from Albendazole even after administering the second dose. In that case, your doctor may give you ivermectin medicine with Albendazole

Ivermectin paralyzes or kills the worms and expels them through stool. It is a potent anthelmintic agent that helps kill and clear your intestinal worms. 

The combination of ivermectin and Albendazole drug is usually prescribed in recurrent or repeated worm infestation. The combination of ivermectin and albendazole oral suspension is available in the market with common brands –

  • Noworm plus
  • Bandy plus
  • Bendex plus
  • Ivoral forte 
  • Ibendzole

It is a safe and effective combination. Even a study published in The Lancet, 2021, has proven the high efficacy of co-administered ivermectin-albendazole over monotherapy of Albendazole.  



Albendazole is a well-tolerated and highly effective anthelmintic drug for the treatment of a variety of parasitic infections in children and adults.
