Generic Albendazole

Common Use
Albendazole is a broad-spectrum anthelmintic (anti-parasitic) medication used to treat various worm infections, including neurocysticercosis (caused by pork tapeworm), echinococcosis (hydatid disease), ascariasis, hookworm, pinworm, and strongyloidiasis. It works by inhibiting the worms’ ability to absorb glucose, leading to their eventual death. It is effective against both intestinal and tissue parasites.

Dosage and Direction
Albendazole is usually taken by mouth with food, especially a fatty meal to increase absorption. Dosage and duration depend on the specific type of infection and patient weight. For some infections, a single dose may be sufficient, while others require treatment over several days or weeks.

Precautions
Inform your doctor if you have liver disease, bone marrow suppression, or a history of seizures. Liver function and blood counts may need to be monitored during long-term treatment. Albendazole should be used with caution during pregnancy and only if clearly needed in the first trimester.

Contraindications
Do not use albendazole if you are allergic to it or to other benzimidazole drugs. It is contraindicated in pregnancy (especially the first trimester) unless the potential benefit justifies the risk. Breastfeeding should be discussed with your healthcare provider.

Possible Side Effects
Common side effects include headache, nausea, vomiting, abdominal pain, and dizziness. More serious side effects include liver enzyme elevation, low white blood cell count, or allergic reactions. Notify your doctor if you experience yellowing of the skin or eyes, unusual fatigue, or signs of infection.

Drug Interaction
Albendazole may interact with drugs that affect liver enzymes, such as dexamethasone, cimetidine, or praziquantel. These interactions can affect blood levels of albendazole. Always inform your doctor about all medications, including over-the-counter and herbal products.

Missed Dose
If you miss a dose, take it as soon as possible. If it is almost time for the next dose, skip the missed dose. Do not double the dose to make up for the missed one.

Overdose
Overdose is rare but may cause symptoms such as vomiting, abdominal discomfort, or dizziness. Seek emergency medical help if an overdose is suspected. Supportive treatment is usually sufficient.

Storage
Store albendazole tablets at room temperature, away from moisture, heat, and light. Keep the medication in its original container and out of reach of children. Do not use after the expiration date.
