Does Amoxicillin Kill Worms In Humans? See The Medications Required For Treatment Of Different Types Of Worms

Amoxicillin is a widely used antibiotic, which is known for tackling bacterial infections. However, the big question many have is “does amoxicillin kill worms in humans?” In this article, we will look into the details of amoxicillin, shedding light on what it does, what it doesn’t do, and answering some common questions.

Amoxicillin Basics

Amoxicillin belongs to the penicillin family, known for it’s effectiveness against bacteria. It’s main job is to stop bacteria from growing by messing with the production of their cell walls. But here’s the key point: it doesn’t work against parasitic worms.

Does Amoxicillin Kill Worms In Humans? Why Amoxicillin Can’t Handle Worms

Parasitic worms, also known as helminths, have a different structure than bacteria. Amoxicillin is designed to combat bacteria, not worms. So, if you’re dealing with roundworms, tapeworms, or flukes, you need a different kind of medication.

Dealing with Worm Infections

If you suspect a worm infection, your best move is to see a healthcare professional. They can accurately diagnose the issue and prescribe the right treatment. Antiparasitic medications are usually prescribed for worms, which are designed specifically to target and eliminate these unwanted guests.

Worm infections which are also known as helminthiasis can affect various parts of the body and lead to a range of symptoms. These parasitic infestations are caused by different types of worms, including roundworms, tapeworms, flukes, and hookworms. we will go further to talk about the common types of worms that infect humans and also look at the drugs used for their treatment.

Common Types of Worms in Humans

  1. Roundworms (Nematodes): These are the most common intestinal parasites in humans. Ascaris lumbricoides is a known example, which causes ascariasis.
  2. Tapeworms (Cestodes): These flat, segmented worms can live in the human digestive tract. Taenia saginata and Taenia solium are tapeworms associated with beef and pork consumption.
  3. Flukes (Trematodes): These flatworms often infect the liver, lungs, or intestines. Schistosoma species are well-known flukes causing schistosomiasis.
  4. Hookworms: Ancylostoma duodenale and Necator americanus are hookworms that infect the small intestine, causing hookworm disease.

Common Symptoms of Worm Infections:

  1. Abdominal pain
  2. Diarrhea or constipation
  3. Nausea
  4. Fatigue
  5. Weight loss
  6. Itching around the rectum or vulva
  7. Visible worms in stool

Treatment Options for Worm Infections


Albendazole is a broad spectrum anthelmintic medication widely used in the treatment of various worm infections in humans. As a member of the benzimidazole class of drugs, albendazole exhibits efficacy against a range of parasitic worms, including roundworms, tapeworms, flukes, and more.

Mechanism of Action

Albendazole interferes with the parasites’ ability to absorb glucose, an important energy source. By binding to the worm’s tubulin protein, it inhibits microtubule formation and disrupts cell division, leading to impaired glucose uptake.  This results in energy depletion, paralysis, and death of the parasitic worms.

Common Uses

  1. Ascariasis (Roundworm Infection): Albendazole is highly effective against Ascaris lumbricoides, the roundworm causing ascariasis. The medication disrupts the worm’s energy metabolism, thereby eliminating the infection.
  2. Taeniasis (Tapeworm Infection): Tapeworms such as Taenia saginata and Taenia solium can be treated with albendazole. The drug’s mechanism of action compromises the tapeworm’s ability to survive in the human digestive tract.
  3. Neurocysticercosis: This parasitic infection involves the presence of cysts in the central nervous system. Albendazole is used to reduce the number of lesions and manage associated symptoms.
  4. Echinococcosis (Hydatid Disease): Caused by the larval stage of the Echinococcus tapeworm, hydatid disease can be treated with albendazole. The drug helps reduce cyst size and prevent further growth.
  5. Fluke Infections: Albendazole is also effective against fluke infections, including those caused by liver flukes (Fasciola hepatica) and lung flukes (Paragonimus spp.).


  • Dosage: The dosage of albendazole depends on the specific infection being treated. It is typically administered as a single oral dose, with some infections requiring repeated doses after a few weeks.
  • Food Interaction: Albendazole is best taken with food, as this enhances it’s absorption and bioavailability.
  • Crushing or Chewing: In general, albendazole tablets should be swallowed whole. Consult a healthcare professional if you have difficulty swallowing.

Considerations and Precautions

  • Pregnancy and Lactation: Albendazole should be used with caution during pregnancy and lactation. Consult a healthcare provider to weigh the potential benefits against the risks.
  • Liver Function: Individuals with liver disease or impaired liver function may require dosage adjustments. Regular monitoring is advisable.
  • Drug Interactions: Inform your healthcare provider about any medications, including herbal supplements, to avoid potential interactions.

Side Effects Of Albendazole

Common side effects may include abdominal pain, nausea, and headache. Serious side effects are rare but seek medical attention if you experience any unusual symptoms.


Mebendazole inhibits the worm’s ability to absorb glucose, impairing their survival and reproduction.

Common uses

Effective against various worms, including roundworms and whipworms.


Usually administered as a single dose, with a second dose recommended in some cases.


Praziquantel disrupts the parasite’s cell membrane, leading to increased permeability and muscle contraction, ultimately causing paralysis and death to the parasite.

Common uses

Primarily used for treating tapeworm and fluke infections.


Administered orally, often as a single dose.


Ivermectin interferes with the nervous system of parasites, causing paralysis and death to them.

Common uses

Effective against certain roundworms and external parasites like mites and lice.


Typically administered as a single oral dose.

General Considerations and Precautions

  • Always consult a healthcare professional for a proper diagnosis before initiating any treatment.
  • Inform your healthcare provider about any existing medical conditions, ongoing medications, or allergies.
  • Follow the prescribed dosage and complete the entire course of treatment, even if symptoms improve.
