Introduction to Albendazole

If you are wondering what albendazole is and how this medicine works, you are in the right place. Albendazole is a commonly-used antiparasitic medicine that treats a number of parasitic worm infections.

It is classified as an anthelmintic medicine and is used to treat all types of parasitic or tissue-inhabiting parasites. But what is albendazole? What makes it work? And when is it used? Let’s look at its uses, mechanism, dosage, safety, and other factors.

What Is Albendazole?

Albendazole is an anthelmintic, or anti-worm, medicine. It belongs to the benzimidazole class of anthelmintics and is used to treat a range of parasitic infections including certain infections from roundworms, hookworms, pinworms and tapeworm larvae.

The medicine works by interfering with some important cellular processes and stops the parasites from getting their nutrients and eventually kill themselves.

Doctors prescribe albendazole for a number of conditions, including neurocysticercosis and hydatid disease as well as some intestinal worm infections. Albendazole is also used in some public-health deworming programmes in regions where parasitic worm infections are common.

How Does Albendazole Work?

Albendazole works primarily by interfering with microtubule formation in parasites.

Microtubules are important structural units in cells and albendazole inhibits the parasite’s ability to form these structures, preventing the parasitic cells from functioning properly.

This means their energy resources will be depleted, which eventually leads to the parasite’s death.

In short, albendazole affects essential processes that the parasite needs to survive.

Medical Uses of Albendazole

So what is albendazole used for? It can be prescribed to treat a number of parasitic worm infections including:

• Hydatid disease (echinococcosis): this infection is caused by the larval stages of the tapeworm, and can form cysts which often affect the liver or lungs
• Neurocysticercosis: this is caused by the pork tapeworm’s larvae entering the body and can affect the brain causing seizures
• Ascariasis: this is an intestinal infection caused by the roundworm, and may cause discomfort
• Hookworm infections: these parasites live in the intestines and can cause blood loss and anaemia
• Pinworm infections: these are common intestinal infections that are often associated with itching around the anal region, especially at night

Albendazole may be used for some other parasitic infections depending on the case.

The appropriate dose and duration of treatment depends on the infective agent, site, and location of infection, patient’s status and other relevant factors. Albendazole should be used in accordance with medical advice.

Dosage and Administration

Albendazole is generally taken by mouth, in the form of either a tablet or chewable tablet depending on which product is used.

The treatment regimen varies considerably depending on the infection. Simple infections like roundworms, pinworms and hookworms can be treated with a single dose, while neurocysticercosis, hydatid disease and others may require more prolonged courses of treatment.

Taking albendazole with a meal that contains some fat in them can increase absorption, but instructions can vary depending on the condition and formulation, so patients should follow what their healthcare professional or on the product information says.

Do not change the dose or length of treatment on your own. And for those undergoing longer treatment, it is very important to complete the course and attend all follow up appointments.

Safety, Side Effects and Precautions

Like most medicines, albendazole can cause side effects, but not everyone suffers from them.

Common side-effects can include:

• Headaches
• Dizziness
• Abdominal discomfort
• Nausea or vomiting
• Diarrhoea

Those on more prolonged or higher-dose treatment may suffer more serious side effects such as liver problems, and altered blood-cell counts and complications such as severe weakness, bruising or an allergic reaction.

If you suffer from any unusual or unexpected symptom such as severe abdominal pain, jaundice (yellowing of the eyes and skin), unexplained bruising or weakness, it is important to seek medical advice.

Those on long treatment may also need to undergo regular blood tests for cell counts and liver function as recommended by their doctor.

Pregnancy, Breastfeeding and Other Precautions

Make sure to tell your healthcare professional if you are pregnant, planning to become pregnant or breastfeeding before taking albendazole.

Depending on the infection and its severity, the decision to take albendazole during pregnancy may be made by your doctor. Do not take albendazole if you are pregnant without medical advice.

Let your doctor know if you have liver disease or are taking other medicines, as it may affect treatment and monitoring.

Albendazole Availability and Prescription in the United Kingdom

The availability and prescription requirements for albendazole can vary, depending on the product and indication, in the United Kingdom.

If you think you have a parasitic infection, it is important to get medical advice rather than treating it on your own. Different parasites require different treatments, and symptoms like abdominal discomfort and diarrhoea can be associated with many other infections.

Your healthcare professional can work out if tests are needed and if albendazole is suitable.

Why Is It Important To Use Albendazole Responsibly?

Using antiparasitic medicines appropriately is important for both your safety and effective treatment.

Not every worm infection needs the same medicine and it’s important to take the correct treatment, the correct dose, and not repeat treatment unnecessarily, to avoid unnecessary side effects and time.

Follow all treatment instructions and attend any follow up appointments as recommended, especially when taking albendazole for a serious infection or for a prolonged period of time.

If you still feel unwell after treatment, seek medical advice rather than taking the medicine repeatedly.

Conclusion

To recap, what is albendazole? It is an anthelmintic medicine used to treat a range of parasitic worm infections. It works by interfering with essential cellular process in parasites, stopping them from getting their nutrients and eventually killing themselves.

The treatment regimen varies depending on infection, and some require only one dose while others require a longer course and regular monitoring by a healthcare professional.

Albendazole is an established treatment for a number of parasitic infections, and should be used appropriately and by professional medical advice. Correct diagnosis and correct dose and follow up is vital for safe and effective treatment.

If you think you might have a parasitic infection or are unsure if albendazole is suitable for you, speak to a qualified healthcare professional before taking it.
