Albendazole Dosage: What You Need to Know

Albendazole is a medicine that fights worm infections. If you’ve been prescribed it, you probably wonder how much to take and for how long. The answer depends on the type of infection, your weight, and sometimes your age. Below we break down the most common dosing schedules so you can follow your treatment correctly.

Standard adult dosing

For most adult infections – like tapeworm, roundworm, or hookworm – the usual dose is 400 mg once a day. Doctors often tell you to take it for three days straight. In some cases, a single 400 mg dose is enough, such as for a simple pinworm infection. Always swallow the tablet with a full glass of water and try to take it with food; that helps your body absorb the drug better.

Special dosing for children

Kids don’t get the same dose as adults. The usual rule is 10 mg per kilogram of body weight, taken once a day. For example, a child who weighs 20 kg would take 200 mg daily. The treatment length is often three days, but some infections need a single dose only. If the child is under two years old, the doctor may choose a different medicine because albendazole isn’t always approved for very young infants.

When the infection is more serious – like neurocysticercosis (a brain tapeworm) – the dose may increase to 800 mg per day, split into two 400 mg tablets. Treatment can last from one week up to several months, depending on how the doctor monitors the infection. In these cases, regular check‑ups and sometimes liver function tests are needed because higher doses can affect the liver.

What to watch for while taking albendazole

Most people tolerate albendazole well. Some may feel mild stomach upset, headache, or dizziness. If you notice rash, severe stomach pain, or yellowing of the skin or eyes, call your doctor right away – those could be signs of a liver issue. Alcohol can make liver problems worse, so it’s a good idea to limit drinking while you’re on the medication.

Don’t skip doses. If you miss a dose, take it as soon as you remember unless it’s almost time for the next one. In that case, just skip the missed dose and continue with your regular schedule. Stopping early can let the worms survive and cause the infection to come back.

Quick FAQ

Can I take albendazole with other medicines? Most drugs are fine, but tell your doctor about any anti‑seizure meds, warfarin, or steroids because they can interact.

Do I need a repeat prescription? For the typical three‑day course, one prescription covers it. Longer treatments will need a follow‑up prescription from your doctor.

Is albendazole safe during pregnancy? It’s generally avoided unless the infection is life‑threatening. Your doctor will weigh the risks and benefits.

Following the exact dosing plan your doctor gives you is the best way to clear the infection quickly and avoid side effects. If you ever feel unsure about the dose, reach out to your pharmacist or doctor – they’re there to help. With the right dose and a few simple safety steps, albendazole can get rid of those unwanted parasites fast.
