Albenza (albendazole) is an anthelmintic medication specifically formulated to combat a range of parasitic worm infections. As a broad-spectrum agent, it works by inhibiting microtubule polymerization in susceptible parasites, leading to energy depletion and immobilization, ultimately causing their death. This mechanism makes it a cornerstone in the management of conditions such as neurocysticercosis and hydatid disease, offering a clinically proven approach to reducing parasitic burden and associated complications. Proper diagnosis and medical supervision are essential for determining appropriate treatment protocols.

Features

• Active ingredient: Albendazole 400 mg
• Pharmaceutical form: Oral tablets
• Mechanism: Inhibits beta-tubulin polymerization in parasites
• Broad-spectrum activity against nematodes and cestodes
• Bioavailability enhanced with fatty food administration
• Manufactured under strict pharmaceutical compliance standards

Benefits

• Effectively reduces cyst count and size in neurocysticercosis
• Decreases risk of complications from hydatid disease
• Provides systematic eradication of intestinal parasites
• Minimizes recurrence through parasitic lifecycle disruption
• Supports improved nutritional absorption in infected patients
• Facilitates recovery through targeted antiparasitic action

Common use

Albenza is primarily indicated for the treatment of parenchymal neurocysticercosis caused by larval forms of Taenia solium. It is also approved for cystic hydatid disease of the liver, lung, and peritoneum caused by Echinococcus granulosus. Off-label uses include treatment of other helminth infections such as ascariasis, trichuriasis, and hookworm infections, though these applications require careful medical evaluation. Diagnosis should be confirmed through imaging and laboratory testing before initiation of therapy.

Dosage and direction

Dosage varies significantly based on infection type, patient weight, and medical evaluation. For neurocysticercosis: 400 mg twice daily with meals for 8-30 days. For hydatid disease: 400 mg twice daily with meals for 28-day cycles followed by 14-day drug-free intervals, typically repeating for 3 cycles. Administration with a fatty meal increases bioavailability approximately 5-fold. Tablets should be swallowed whole with water. Dosage adjustments are necessary for patients with hepatic impairment. Complete the full prescribed course unless directed otherwise by a physician.

Precautions

Monitor liver function tests before and during treatment due to potential hepatotoxicity. Complete blood counts should be performed regularly as albendazole may cause bone marrow suppression. Corticosteroid therapy should be administered concurrently for neurocysticercosis to prevent cerebral inflammation. Pregnancy must be excluded before initiation and prevented during therapy. Use effective contraception during and for one month after treatment completion. Retinal examination is recommended in patients with retinal involvement. Not recommended for children under 1 year old.

Contraindications

Hypersensitivity to albendazole, benzimidazole derivatives, or any component of the formulation. Contraindicated in pregnancy due to potential fetal harm. Avoid use in patients with significant hepatic impairment without careful risk-benefit assessment. Not recommended for treatment of neurocysticercosis involving the eye. History of bone marrow suppression requires alternative treatment consideration.

Possible side effect

Common adverse reactions include: elevated liver enzymes (15-20%), abdominal pain (6%), nausea (4-6%), vomiting (4%), headache (3-5%), dizziness (2-4%), and temporary alopecia (2%). Serious side effects may include: hepatotoxicity, pancytopenia, neutropenia, thrombocytopenia, and Stevens-Johnson syndrome. Most side effects are dose-related and reversible upon discontinuation. Regular monitoring helps detect and manage adverse effects promptly.

Drug interaction

Cimetidine, dexamethasone, and praziquantel may increase albendazole sulfoxide levels. Antiepileptic drugs (carbamazepine, phenytoin, phenobarbital) may decrease albendazole levels. Theophylline levels may be increased with concurrent use. Monitor patients on warfarin therapy closely as albendazole may affect coagulation parameters. Concomitant use with other hepatotoxic drugs requires enhanced monitoring.

Missed dose

If a dose is missed, take it as soon as remembered unless it is nearly time for the next dose. Do not double the dose to make up for a missed administration. Maintain regular dosing schedule to ensure consistent therapeutic levels. Contact healthcare provider if multiple doses are missed for guidance on regimen adjustment.

Overdose

Symptoms may include nausea, vomiting, dizziness, or elevated liver enzymes. In case of suspected overdose, seek immediate medical attention. Gastric lavage may be considered if administered shortly after ingestion. Supportive care and symptomatic treatment are mainstays of management. No specific antidote exists. Dialysis is unlikely to be effective due to high protein binding.

Storage

Store at controlled room temperature (20-25°C/68-77°F). Keep container tightly closed and protect from moisture. Keep out of reach of children and pets. Do not use after expiration date printed on packaging. Do not transfer tablets to other containers as this may affect stability. Discard any medication that appears discolored or damaged.

Always follow the prescribed treatment plan and report any adverse effects to your healthcare provider promptly.

Reviews

Clinical studies demonstrate efficacy rates of 70-90% for neurocysticercosis and 30-50% cyst disappearance in hydatid disease with multiple cycles. Patients report significant improvement in symptoms following completed treatment courses. Medical professionals emphasize the importance of combination therapy with steroids for neurocysticercosis management. Long-term follow-up studies show reduced seizure frequency in successfully treated neurocysticercosis patients. Adherence to full treatment duration is consistently correlated with improved outcomes across indications.
