Albendazole

Albendazole is used to treat neurocysticercosis (infection caused by the pork tapeworm in the muscles, brain, and eyes that may cause seizures, brain swelling, and vision problems). Albendazole is also used along with surgery to treat cystic hydatid disease (infection caused by the dog tapeworm in the liver, lung, and lining of the abdomen that may damage these organs). Albendazole is in a class of medications called antihelmintics. It works by killing the worms.

🔔 How should this medicine be used?

Albendazole comes as a tablet to take by mouth. It is usually taken with food twice a day. When albendazole is used to treat neurocysticercosis, it is usually taken for 8 to 30 days. When albendazole is used to treat cystic hydatid disease, it is usually taken for 28 days, followed by a 14-day break, and repeated for a total of three cycles. Take albendazole at around the same times every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take albendazole exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

If you are giving the medication to a child or if you cannot swallow the tablets whole, you may crush or chew the tablets and swallow the medication with a drink of water.

Take albendazole until you finish the prescription, even if you feel better. If you stop taking albendazole too soon or skip doses, your infection may not be completely treated.

🔔 What should I know about storage and disposal of this medication?

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org

Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA’s Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.

🔔 In case of emergency/overdose

In case of overdose, call the poison control helpline at 1-800-222-1222. Information is also available online at https://www.poisonhelp.org/help. If the victim has collapsed, had a seizure, has trouble breathing, or can’t be awakened, immediately call emergency services at 911.

🔔 What other information should I know?

Keep all appointments with your doctor and the laboratory. Your doctor may order an eye exam before beginning your treatment. Your doctor will also order certain lab tests during your treatment to check your body’s response to albendazole.

Do not let anyone else take your medication. Ask your pharmacist any questions you have about refilling your prescription.

It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
