Albendazole is a broad-spectrum anthelmintic (anti-parasitic) medication widely used in humans to treat infections caused by intestinal and tissue-dwelling worms. It belongs to the benzimidazole class of drugs and works by inhibiting the parasites’ ability to absorb glucose, leading to depletion of their energy stores and eventual death.Albendazole 400 mg is listed as an essential medicine by the World Health Organization due to its effectiveness and importance in public health. In humans, albendazole is commonly prescribed for intestinal worm infections such as roundworm (ascariasis), hookworm, whipworm (trichuriasis), and pinworm (enterobiasis). It is also effective against tapeworm infections, including neurocysticercosis caused by the larval form of Taenia solium, and hydatid disease (echinococcosis) caused by Echinococcus species. These conditions are more prevalent in areas with poor sanitation but can affect individuals worldwide.Albendazole is usually taken orally, either as a tablet or suspension, and is often administered with food to improve absorption, especially in tissue infections. The duration of treatment varies depending on the type and severity of infection, ranging from a single dose for simple intestinal worms to prolonged therapy for conditions like hydatid disease or neurocysticercosis. Because treatment regimens differ, albendazole should always be used under medical supervision.Most people tolerate albendazole well. Common side effects include nausea, abdominal pain, headache, dizziness, and temporary hair loss with long-term use. In some cases, mild elevations in liver enzymes may occur, so liver function monitoring is recommended during extended treatment. Albendazole is generally not advised during the first trimester of pregnancy due to potential risks to the developing fetus.Beyond individual treatment, albendazole plays a key role in mass deworming programs aimed at reducing the burden of parasitic diseases, particularly among children. By improving nutritional status, growth, and overall health, albendazole contributes significantly to public health and disease prevention.
