The Pharmacist’s Take By · Clinical pharmacist · Written

Albendazole is a prescription antiparasitic drug, on the U.S. market since about 1996 and available as a generic, that is a standard first choice for neurocysticercosis (pork tapeworm larvae in the brain) and hydatid disease (dog tapeworm cysts in the liver, lungs or abdomen), and it starves the parasite of sugar. Most people tolerate it reasonably well, and stomach pain, nausea, headache and dizziness are the usual complaints. Its serious risks are bone marrow suppression (rarely fatal) and liver injury, so expect blood counts and liver tests and report bruising, bleeding, infection or yellowing skin promptly. During treatment for the brain infection, seizures, severe headache or vision changes need urgent care.

Clinical pearls

  • Take it with a meal containing some fat, which markedly improves absorption; the tablets may be crushed or chewed with water.
  • Women who could become pregnant need a negative pregnancy test first and effective contraception during treatment, since it can harm a developing baby.
  • Before neurocysticercosis treatment, expect an eye exam for retinal cysts; the steroid dexamethasone, often given alongside, also raises albendazole levels.
  • If you take theophylline for a lung condition, its blood levels should be checked during and after albendazole treatment.

What Albendazole is used for

▾

Albendazole is an antiparasitic (anthelmintic) medication approved to treat two serious tapeworm infections:

  • Neurocysticercosis: Albenza (albendazole) tablets and generic albendazole tablets are both indicated to treat active parenchymal neurocysticercosis — an infection of brain tissue caused by the larval form of the pork tapeworm, Taenia solium.
  • Cystic hydatid disease: Albenza (albendazole) tablets and generic albendazole tablets are both indicated to treat cystic hydatid disease of the liver, lung, and peritoneum (the lining of the abdomen), caused by the larval form of the dog tapeworm, Echinococcus granulosus.

How Albendazole works

▾

Albendazole is a benzimidazole-class drug that works by attaching to a protein called beta-tubulin inside the parasite. This protein is essential for building the parasite's internal scaffolding. When albendazole blocks it, the parasite's intestinal cells lose their ability to absorb glucose (sugar). Without glucose, the parasite can't produce energy (ATP) and eventually dies. Albendazole itself converts almost immediately in the liver to its active form, albendazole sulfoxide, which is what does the work throughout the body — reaching the liver, cysts, cerebrospinal fluid (the fluid around the brain and spine), and other tissues.

Parasites can develop resistance to albendazole through changes in the beta-tubulin protein that reduce drug binding, though this is not commonly a clinical concern in the approved treatment settings.

Albendazole dosage

▾

Albendazole tablets are taken by mouth, twice daily, with meals. Taking them with a fatty meal is important — it can increase absorption of the active drug by up to 5 times compared to taking it on an empty stomach. The tablets can be crushed or chewed and swallowed with water.

  • Hydatid disease: Treatment follows a 28-day-on, 14-day-off cycle, repeated for a total of 3 cycles, as directed by your prescriber.
  • Neurocysticercosis: Treatment is typically a continuous course lasting 8 to 30 days, as directed by your prescriber.

Your exact dose and schedule depend on your weight and your condition. Always follow your prescriber's instructions and your prescription label closely.

Albendazole side effects

▾

The most common side effects of albendazole vary a little depending on which condition is being treated:

Common side effects

  • Elevated liver enzymes (detected on blood tests)
  • Abdominal pain
  • Nausea or vomiting
  • Headache
  • Dizziness or vertigo
  • Reversible hair loss (alopecia)
  • Fever
  • In hydatid disease: elevated liver enzymes (seen in about 16% of patients), abdominal pain, nausea, vomiting, reversible hair loss, headache, dizziness, vertigo, and fever
  • In neurocysticercosis: headache, nausea, vomiting, raised pressure inside the skull, and meningeal signs (stiff neck or other signs of brain irritation)
  • Less common but reported: diarrhea, drowsiness, blurred vision, and weakness

When to get medical help

  • Call your doctor right away if you notice unusual bruising, bleeding, or signs of infection — albendazole can suppress bone marrow and reduce blood cell counts, which has caused deaths in rare cases
  • Seek medical help immediately if you experience seizures, sudden neurological changes, or signs of increased pressure in the skull (severe headache, vision changes, confusion) — especially during treatment for neurocysticercosis
  • Tell your doctor promptly if you develop yellowing of skin or eyes, severe nausea, or upper abdominal pain — these may signal serious liver problems
  • If you are pregnant or become pregnant during treatment, contact your doctor immediately — albendazole can cause serious harm to a developing baby
  • Get emergency care for a severe skin reaction such as blistering, peeling, or widespread rash — rare but serious skin reactions have been reported

Seek immediate medical attention if you experience signs of low blood counts (unusual bruising, bleeding, or frequent infections), severe liver symptoms (yellowing of skin or eyes, dark urine, severe abdominal pain), seizures, serious skin reactions (blistering, peeling rash), or signs of kidney problems. These are rare but serious.

Albendazole warnings and precautions

▾
  • Bone marrow suppression (the most serious risk): Albendazole can reduce the production of blood cells, leading to dangerously low white blood cell or platelet counts. Deaths have been reported. Blood counts must be monitored at the start of each 28-day cycle and every two weeks during treatment. Patients with liver disease or hepatic echinococcosis face higher risk and need even more frequent monitoring.
  • Risk to unborn babies: Albendazole has caused birth defects and fetal death in animal studies. A pregnancy test is required before starting treatment. Women who can become pregnant must use effective contraception during treatment and for 3 days after the last dose.
  • Liver injury: Elevated liver enzymes are common (about 16% of patients). Rare cases of hepatitis and acute liver failure have also been reported. Liver enzymes must be checked before each cycle and at least every 2 weeks during treatment.
  • Neurological reactions in neurocysticercosis: Killing the parasite in the brain can trigger inflammation, causing seizures, increased brain pressure, or other neurological symptoms. Steroids and anti-seizure medications are often given alongside albendazole to reduce this risk.
  • Retinal damage risk: If cysticercosis has spread to the retina (back of the eye), treating it can cause retinal damage from inflammation. Your doctor should examine your eyes before starting treatment for neurocysticercosis.
  • Hidden neurocysticercosis: In patients being treated for other conditions, undiagnosed neurocysticercosis may be uncovered during albendazole therapy. Those at risk should be evaluated first.

Albendazole interactions

▾

Albendazole can interact with several medications, affecting how much drug is in your bloodstream:

  • Dexamethasone (a steroid): Raises albendazole sulfoxide blood levels by about 56%. Doctors treating neurocysticercosis often prescribe both together intentionally, but the interaction should be factored into monitoring.
  • Praziquantel (another antiparasitic): Increases albendazole sulfoxide blood levels by about 50% when taken together in the fed state.
  • Cimetidine (used for heartburn or ulcers): Roughly doubles albendazole levels in bile and cyst fluid, which could affect how the drug acts in hydatid cysts.
  • Theophylline (used for asthma or lung conditions): Albendazole may increase how quickly the body breaks down theophylline; blood levels of theophylline should be monitored during and after albendazole treatment.

Interactions listed in the FDA-approved label

From the Albendazole prescribing information (“Drug Interactions”): what the manufacturer studied or reported to the FDA.

  • Dexamethasone: Steady-state trough concentrations of albendazole sulfoxide were about 56% higher when 8 mg dexamethasone was co-administered with each dose of albendazole (15 mg/kg/day) in 8 neurocysticercosis patients.
  • Praziquantel: In the fed state, praziquantel (40 mg/kg) increased mean maximum plasma concentration and area under the curve of albendazole sulfoxide by about 50% in healthy subjects.
  • Cimetidine: Albendazole sulfoxide concentrations in bile and cystic fluid were increased about 2-fold in hydatid cyst patients treated with cimetidine; plasma concentrations were unchanged 4 hours after dosing.
  • Theophylline: Albendazole induces cytochrome P450 1A in human hepatoma cells; theophylline pharmacokinetics were unchanged after a single albendazole dose (400 mg). Monitor plasma concentrations of theophylline during and after treatment.

7 DRUG INTERACTIONS Dexamethasone: Steady-state trough concentrations of albendazole sulfoxide were about 56% higher when dexamethasone was coadministered with each dose of albendazole. ( 7.1 ) Praziquantel: In the fed state increased mean maximum plasma concentration and area under the curve of albendazole sulfoxide by about 50% in healthy subjects. ( 7.2 ) Cimetidine: Increased albendazole sulfoxide concentrations in bile and cystic fluid by about 2-fold in hydatid cyst patients. ( 7.3 ) Theophylline: Albendazole induces cytochrome P450 1A in human hepatoma cells; therefore, it is recommended that plasma concentrations of theophylline be monitored during and after treatment. ( 5.5 , 7.4 ) 7.1 Dexamethasone Steady-state trough concentrations of albendazole sulfoxide were about 56% higher when 8 mg dexamethasone was co-administered with each dose of albendazole (15 mg/kg/day) in 8 neurocysticercosis patients. 7.2 Praziquantel In the fed state, praziquantel (40 mg/kg) increased mean maximum plasma concentration and area under the curve of albendazole sulfoxide by about 50% in healthy subjects (n = 10) compared with a separate group of subjects (n = 6) given albendazole alone. Mean T max and mean plasma elimination half-life of albendazole sulfoxide were unchanged. The pharmacokinetics of praziquantel were unchanged following co-administration with albendazole (400 mg). 7.3 Cimetidine Albendazole sulfoxide concentrations in bile and cystic fluid were increased (about 2-fold) in hydatid cyst patients treated with cimetidine (10 mg/kg/day) (n = 7) compared with albendazole (20 mg/kg/day) alone (n = 12). Albendazole sulfoxide plasma concentrations were unchanged 4 hours after dosing. 7.4 Theophylline Following a single dose of albendazole (400 mg), the pharmacokinetics of theophylline (aminophylline 5.8 mg/kg infused over 20 minutes) were unchanged.

Before taking Albendazole

▾
  • Do not take albendazole if you have had a serious allergic reaction to albendazole, mebendazole, or any other benzimidazole-class drug.
  • Tell your doctor if you are pregnant or may become pregnant — albendazole can harm a developing baby. A pregnancy test is required before starting. Use effective birth control during treatment and for 3 days after the final dose.
  • Tell your doctor if you are breastfeeding — albendazole and its active form pass into breast milk at low levels; discuss the risks and benefits with your provider.
  • Tell your doctor if you have liver disease or bile duct problems — these conditions can increase your exposure to the drug and raise your risk of serious side effects.
  • Patients being treated for neurocysticercosis should have an eye exam before starting treatment to check for retinal cysts.
  • If you are at risk for neurocysticercosis (due to geographic or exposure factors), your doctor should evaluate you for this condition before starting albendazole for any other reason.
  • Tell your doctor all medications you take, especially dexamethasone, praziquantel, cimetidine, or theophylline.
  • Older adults (65+): Limited data are available; your doctor will monitor you closely.
  • Children: For neurocysticercosis, albendazole appears similarly effective in children as in adults. Hydatid disease is uncommon in young children.

Albendazole overdose

▾

The label does not describe specific symptoms of albendazole overdose. If an overdose is suspected, symptomatic treatment and general supportive care are recommended. Contact Poison Control or seek emergency medical help right away.

What Albendazole does in the body

▾

Albendazole works by blocking the parasite's ability to take up glucose — its primary energy source. By binding to beta-tubulin and preventing proper microtubule formation in the parasite's gut cells, the drug depletes the parasite's glycogen (stored sugar) and halts energy production (ATP). Without energy, the parasite dies. This action targets both adult and larval forms of the parasites in the approved treatment indications.

How your body processes Albendazole

▾

Albendazole is poorly absorbed from the gut on its own, but absorption rises dramatically — up to 5 times higher — when taken with a fatty meal. It is rapidly converted in the liver to its active form, albendazole sulfoxide, before it even enters the bloodstream; the parent drug is rarely detectable in blood or urine. The active metabolite is about 70% bound to proteins in the blood and distributes widely throughout the body, including into cyst fluid and cerebrospinal fluid (the fluid around the brain and spinal cord). It is processed further in the liver and cleared primarily through bile; less than 1% leaves the body in urine. The active form has a half-life (the time for blood levels to fall by half) of about 8 to 12 hours. With prolonged treatment, albendazole may speed up its own breakdown, leading to somewhat lower drug levels over time.

Albendazole: pharmacist answers to common questions

Quick, plain-English answers to the questions patients ask most about Albendazole — the kind of thing our pharmacy team would talk through with you at the counter.

What exactly is albendazole used for?

▾
Albendazole is used to treat two serious parasitic infections caused by tapeworm larvae. One is neurocysticercosis, where tapeworm larvae infect the brain and nervous system after someone ingests eggs of the pork tapeworm. The other is cystic hydatid disease, where the dog tapeworm's larvae form cysts in organs like the liver or lungs. These are not everyday stomach worms — they are more serious infections that need prescription treatment and close medical follow-up.

Do I have to take it with food? Does it really matter?

▾
Yes, it really does matter. Taking albendazole with a fatty meal — like something containing healthy fats — can increase the amount of active drug that gets into your system by up to five times compared to taking it on an empty stomach. That's a huge difference. So please don't skip food when you take your dose. If you have questions about what counts as a 'fatty enough' meal, ask your pharmacist.

What side effects should I expect, and which ones mean I should call my doctor?

▾
Common side effects include nausea, vomiting, stomach pain, headache, dizziness, and sometimes temporary hair thinning — these are usually mild and go away after treatment ends. Elevated liver enzymes on blood tests are also common, which is why your doctor checks them regularly. Call your doctor right away if you notice unusual bruising, bleeding, or frequent infections (signs of blood count problems), yellowing of your skin or eyes, severe abdominal pain (possible liver issues), or any new neurological symptoms like seizures or sudden severe headache. These are uncommon but serious and need prompt attention.

I'm being treated for the brain infection (neurocysticercosis). Why am I also taking steroids?

▾
That's a great question. When albendazole kills the parasite inside your brain, your immune system reacts to it — and that inflammatory reaction can cause swelling, seizures, or increased pressure in the skull. Steroids help calm that inflammation and reduce the risk of those complications. Your doctor may also prescribe anti-seizure medication as a precaution. It's actually part of the standard treatment plan, not a sign that something is going wrong.

Is this medication safe during pregnancy?

▾
Albendazole should not be taken during pregnancy if it can be avoided. Animal studies have shown it can cause birth defects and harm the developing baby. Your doctor will require a pregnancy test before starting this medication. If you are a woman who could become pregnant, you'll need to use effective contraception during your entire treatment course and for 3 days after your last dose. If you accidentally become pregnant during treatment, contact your doctor right away. The risks need to be discussed openly with your care team.

Will my doctor be monitoring me while I'm on this medication? Why?

▾
Yes — regular monitoring is an important part of treatment. Your doctor will check your blood counts and liver enzymes before you start, then regularly throughout treatment — typically every two weeks. That's because albendazole can sometimes affect the bone marrow (which makes blood cells) and the liver, and catching any changes early is important. These blood tests aren't just routine paperwork; they're a real safety measure. Make sure you keep those follow-up appointments.

Is Albendazole available over the counter?

▾
No. Albendazole is a prescription medicine: every Albendazole product listed with the FDA is prescription only, so it is not sold over the counter. Your prescriber decides whether it is appropriate for you, and your pharmacist dispenses it.

When was Albendazole first available?

▾
The earliest FDA record we hold for Albendazole is from 1996: its first approval in Drugs@FDA or its earliest product listing in the NDC Directory, whichever is older. Many older medicines were in use before their first formal FDA approval, so this is the earliest date on record, not necessarily when Albendazole was first used.

Who makes Albendazole?

▾
10 companies currently list Albendazole products in the FDA's NDC Directory, including Actavis Pharma, Inc., Alembic Pharmaceuticals Inc., Alembic Pharmaceuticals Limited. That count includes repackagers and distributors as well as manufacturers (companies that sell only the raw ingredient are not counted), so fewer companies actually make it; the label on your bottle names the one that supplied yours.

Albendazole side effects reported to the FDA (FAERS)

After a medicine reaches the market, patients, doctors and drugmakers can send the FDA reports of problems they think may be linked to it. Here’s what’s been reported for Albendazole — a signal of what to watch for, not proof the drug caused it.

The effects most often named in FDA reports that mention Albendazole are pyrexia, headache, condition aggravated; about 86% of the reports were classed as serious. These are voluntary reports, so they show what people report, not how often it happens.

Source: openFDA, from the FDA Adverse Event Reporting System (FAERS). These are voluntary reports — they don’t prove the drug caused the effect, and counts reflect how often something was reported, not how often it actually happens. Reports also often name the very problem the medicine is taken for — a common reason to file one is that the drug didn’t help — so for a pain reliever you may see “pain” high on the list; that points to why the report was filed, not to the drug causing the symptom. This counts every report that lists Albendazole in any role, so the total runs higher than the FDA’s official dashboard, which counts only cases where the drug is the suspect. For the authoritative figures, see the FDA FAERS Public Dashboard. Always talk to your pharmacist or doctor.

💵 What Albendazole costs pharmacies (NADAC benchmark)

The national average invoice price pharmacies pay for the drug itself, from CMS's NADAC survey (data as of Sep 30, 2026). This is a supply-cost benchmark — not a retail price and not what you'd pay at the counter.

FormStrengthPharmacy acquisition benchmark
Tablet, Film Coated · Oral 200 mg $12.61 per tablet NDC details & price history
Tablet · Oral 200 mg $4.15 per tablet NDC details & price history
Tablet, Film Coated 200 mg $4.15 per tablet NDC details & price history
Why show this? Your out-of-pocket cost depends on insurance, pharmacy markup, and discounts — but the acquisition benchmark tells you whether the medication itself is inexpensive or costly, which strengths cost more per dose, and whether a cash-price quote is in a reasonable range. Each row links to the NDC-level record with its full price history.
