Introduction to Albendazole Dosage for Adults

Albendazole is an antiparasitic medicine which treats a number of worm infections. If you are looking for albendazole dosage information for adults, it is critical to note that the correct dose is dependent on the type of infection being tackled.

This guide provides the general adult dosing principles, how to take it and precautions. As treatment regimes can vary considerably between parasitic infections, always follow the recommendations of your healthcare professional.

What Is Albendazole?

Albendazole belongs to a class of medicines known as anthelmintics and acts to treat infections with certain parasitic worms including roundworms, hookworms, pinworms and some tapeworm infections.

Albendazole 400 mg will interfere with vital processes within susceptible parasites including their ability to receive nutrition, eventually leading to the death of these organisms.

Why It Matters

Getting the dose right when taking albendazole is important to get an effective and safe treatment.

The dose may vary depending upon which parasite is infecting, where this parasite is located, the severity of the condition, the age and health of the patient and whether another medicine is being taken as well.

Getting an inadequate dose means it is unlikely there will be an effective resolution to the infection whereas taking too much can raise the risk of experiencing adverse effects.

General Albendazole Dosage Guidelines for Adults

There is no established standard adult albendazole dosage which can be applied to all parasitic infections.

For some simple infections of the intestines with worms, a 400 mg single dose could potentially be used as a treatment. Some infections, such as pinworm, may need a second dose approximately two weeks later as the first treatment may not reliably address new eggs which are swallowed.

More severe infections will need a completely different treatment schedule. Conditions such as neurocysticercosis and hydatid disease may need a weight-dependent albendazole dose, being taken more than once per day and continuing for a considerably longer period of time under specialist supervision.

As a result of these factors, do not use the same treatment for every worm infection.

How to Take It

Albendazole is taken orally. Depending on the infection and formulation, it can be taken with food and, where a high systemic level of the drug is beneficial, may be taken with a fatty diet which will boost absorption.

The instructions can be different depending on the condition which is being treated.

Tablets can either be swallowed or, where appropriate to the formulation, chewed or crushed as instructed on the product. Do not always assume every tablet must be eaten in the same manner as prescribed. If you miss a dose as part of a multiple-dose treatment, you should take it as soon as you are reminded unless it is very close to the time when the next one is due. Always follow the recommended directions on your prescription or the medicine label rather than making assumptions about how to take every dose.

Specific Dosage Instructions for Common Adult Parasitic Infections

1. Treating Intestinal Parasites

For some simple intestinal worm infections, such as ascariasis, hookworm infection or trichuriasis, albendazole could be prescribed at a dosage of 400 mg – though this might either be as a single dose or on a different schedule depending upon the specific parasite.

Pinworm treatment may also be prescribed as a 400 mg dose with a second treatment approximately two weeks later. The repeat treatment is necessary as the medication may kill the worms but not all of their eggs.

The exact regimen must be decided by the diagnosis and a healthcare professional.

2. Neurocysticercosis Treatment

Neurocysticercosis is a more severe condition caused by the larval form of the pork tapeworm and can affect the brain or other tissues.

Treatment is not a standard simple treatment. Albendazole dosage for neurocysticercosis is based on body weight and is dependent upon the number, location and type of cysts.

The treatment may be administered for several days or longer, with the need for additional medicines depending on the situation.

Because treatment can provoke inflammation where the parasites previously were, it is best to let this condition be managed by a healthcare professional, potentially with specialist input.

3. Treatment of Hydatid Disease

Hydatid or echinococcosis disease is caused by the larval form of certain tapeworms and affects the liver or lungs most commonly.

Albendazole may be used for an extended period of time and in accordance with a specialty treatment plan. Dosage is based upon weight and may involve cycle repeated treatments dependent on type, size and location of the cysts and whether surgery or another procedure is required.

During prolonged albendazole treatment, patients may benefit from having regular blood counts and liver-function tests.

Precautions and Safety Information

Before starting albendazole, inform your doctor regarding any pre-existing health conditions, particularly liver disease. Albendazole can have an effect on liver enzymes and may need to be monitored in the longer term during treatment.

Inform your healthcare professional regarding all medicines and supplements taken, as these may impact the action of this medication.

Women who are pregnant, suspected of being pregnant or who are planning to become pregnant should speak to their doctor concerning albendazole use. The decision to use this medication during pregnancy is dependent upon the type and severity of the infection and the potential benefit and risk for both mother and child.

Side Effects

Many people will be fine when taking albendazole for a short period of time, but side effects can occur.

Common side effects are likely to include:

• Headache
• Dizziness
• Abdominal discomfort or pain
• Nausea or vomiting
• Diarrhoea

Prolonged or higher dose treatment can raise the risks of liver problems and alterations in blood-cell counts.

Seek medical advice urgently if you notice yellowing of the skin or eyes, unusual bruising or bleeding, extreme or persistent weakness, or any other concerning or sudden symptoms.

When and How to Consult a Doctor

Albendazole should be taken in accordance with appropriate medical advice, particularly for treatment which requires a multi-dose regime or a long course of treatment.

If symptoms persist following treatment or worsen, speak to a healthcare professional rather than automatically requesting another treatment regime.

A medical professional may wish to perform additional tests to confirm whether the infection persists or whether alternate symptoms are responsible for the discomfort.

Do not alter the recommended dosage, extend treatment or discontinue a course without professional advice.

Summary

Understanding Albendazole dosage for adults is important, but there is no single standard which can apply for every parasitic infection.

Some simple infections of the intestines with worms can be treated by a simple single 400 mg dose of albendazole whereas neurocysticercosis and hydatid disease may have a treatment regime which is heavily weight-dependent, longer and requires careful monitoring.

Take albendazole in the manner as prescribed by your healthcare professional and follow instructions regarding your specific formulation. During prolonged treatment, make sure to follow any monitoring of blood tests or liver function.

If you are unsure whether albendazole is appropriate for your symptoms or which dose to follow, speak to a qualified healthcare professional in the United Kingdom regarding your concerns.
