What Albendazole is used for
Albendazole is a medicine prescribed by ophthalmologists to treat specific eye conditions caused by parasitic infections. It is effective against:
- Ocular cysticercosis: This is a condition where tapeworm cysts are found within the eye.
- Orbital cysticercosis: This refers to tapeworm cysts located in the orbit, which is the bony cavity surrounding the eyeball.
These conditions are caused by the larval stage of a tapeworm, and Albendazole helps in eliminating these parasites.
Cysticercosis can affect various parts of the body, including the eyes. When it affects the eyes, it can lead to a range of symptoms depending on where the cyst is located and its size. Early diagnosis and appropriate treatment are crucial to prevent potential vision loss or other complications.
At Pristine Eye Hospitals, our specialists carefully diagnose the exact location and nature of the cyst before recommending the most suitable treatment plan, which may include Albendazole.
How it works
Albendazole works by targeting and killing the tapeworm cysts that cause ocular and orbital cysticercosis. When you take Albendazole tablets, the medicine is absorbed into your body and reaches the parasitic cysts in your eye or orbit. It acts by disrupting the parasite’s ability to absorb glucose, which is essential for its survival. This effectively starves the parasite, leading to its death and eventual resolution.
The goal of this treatment is to eliminate the parasite and prevent further damage to the eye structures. It’s important to understand that while Albendazole kills the cyst, the body’s reaction to the dying parasite can sometimes cause inflammation. This is why your doctor will often prescribe other medicines alongside Albendazole to manage this reaction.
How it’s used
Albendazole is a tablet that you take by mouth. It is crucial to follow your ophthalmologist’s instructions precisely for the best results and to minimise potential side effects.
The typical dosing for Albendazole in treating ocular and orbital cysticercosis is:
- Strength: 400 mg tablet
- Frequency: Twice a day
- Duration: For 4 weeks
It is very important that Albendazole is taken WITH corticosteroid cover. Your doctor will prescribe corticosteroids (steroids) along with Albendazole. These steroids help to manage the inflammation that can occur when the parasite cyst dies and releases its contents into your body. Do not skip or stop taking your steroid medication unless advised by your doctor.
Always take the tablets with food to improve absorption and reduce stomach upset. Swallow the tablet whole with a glass of water. Do not chew or crush it unless specifically instructed by your doctor.
If you miss a dose, take it as soon as you remember. However, if it is almost time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not double the dose to make up for a missed one.
Completing the full course of treatment, even if your symptoms improve, is vital to ensure the complete eradication of the parasite and prevent recurrence.
Always follow your ophthalmologist’s exact instructions.

Precautions & side effects
When taking Albendazole, it is essential to be aware of certain precautions to ensure your safety and the effectiveness of the treatment:
- Steroid Cover is Essential: As mentioned, taking corticosteroids along with Albendazole is critical. When the Albendazole kills the parasite cyst, the dying cyst can release substances (antigens) that can trigger a severe inflammatory reaction in your body, especially in the eye. Corticosteroids help to suppress this inflammation and protect your eye from damage. Never take Albendazole without the prescribed steroid cover.
- Intraocular Cysts May Need Surgery: If the tapeworm cyst is located inside the eyeball (intraocular), tablets alone may not be sufficient. Such cysts often require surgical removal in addition to or instead of medical treatment with Albendazole. Your ophthalmologist will determine the best course of action based on the exact location and nature of the cyst.
- Prescription Medicine: Albendazole is a prescription-only medicine. It should only be used under the direct supervision and guidance of a qualified ophthalmologist. Do not self-medicate or use an old prescription without consulting your doctor.
- Monitoring: Your doctor may recommend regular check-ups and possibly blood tests during your treatment to monitor your progress and check for any potential side effects.
- Inform Your Doctor: Always inform your doctor about any other medications you are taking, including over-the-counter drugs, supplements, and herbal remedies, as these can sometimes interact with Albendazole. Also, inform them about any existing medical conditions you have, especially liver or kidney problems.
- Pregnancy and Breastfeeding: If you are pregnant, planning to become pregnant, or breastfeeding, discuss this with your doctor before starting Albendazole.
If you experience any unusual or severe symptoms while on Albendazole, contact your ophthalmologist immediately.
Understanding Ocular and Orbital Cysticercosis
Ocular and orbital cysticercosis are conditions caused by an infection with the larval stage of a tapeworm, specifically Taenia solium. This infection occurs when a person accidentally ingests microscopic eggs of the tapeworm, often through contaminated food or water. Once ingested, these eggs hatch in the intestines, and the larvae then travel through the bloodstream to various parts of the body, including the eyes and the surrounding orbital tissues, where they form cysts.
The symptoms of ocular or orbital cysticercosis can vary widely depending on the exact location, size, and number of cysts. In the eye, a cyst might appear as a visible lump, cause redness, pain, blurred vision, or even lead to vision loss if it affects critical structures like the retina or optic nerve. If the cyst is in the orbit (the area around the eyeball), it might cause swelling, pain, bulging of the eye (proptosis), or restricted eye movement. Sometimes, the presence of a cyst might only be discovered during a routine eye examination.
Diagnosing these conditions typically involves a thorough eye examination by an ophthalmologist, often supplemented by imaging tests such as ultrasound, CT scans, or MRI scans to precisely locate the cyst and assess its impact on the surrounding tissues. Early and accurate diagnosis is crucial for effective treatment and to prevent long-term complications, including permanent vision impairment.
General Advice for Taking Oral Medicines for Eye Conditions
While many eye conditions are treated with eye drops or ointments, some, like cysticercosis, require systemic treatment with oral medicines like Albendazole. It’s important to take these medicines correctly to ensure they work effectively and safely.
Always follow your doctor’s instructions regarding the dosage, frequency, and duration of your medication. Do not alter the dose or stop taking the medicine without consulting your ophthalmologist, even if you start feeling better. Stopping treatment prematurely can lead to the infection not being fully cleared, potentially causing a recurrence or making it harder to treat in the future.
Oral medicines are usually taken with water. Some medicines are best taken with food to reduce stomach upset or improve absorption, while others might need to be taken on an empty stomach. Your doctor or pharmacist will provide specific instructions for Albendazole, which is typically taken with food.
Store your medicine as directed, usually in a cool, dry place away from direct sunlight and out of reach of children. Check the expiry date on the packaging and do not use expired medicines.
If you experience any unexpected side effects or have concerns about your medication, contact your ophthalmologist or the hospital immediately. Keep a list of all your current medications, including over-the-counter drugs and supplements, to share with your doctor, as some medicines can interact with each other.
When to Seek Medical Help
Your ophthalmologist will monitor your progress closely while you are on Albendazole treatment. However, it is important for you to be aware of situations where you should seek immediate medical attention.
Contact Pristine Eye Hospitals or your ophthalmologist without delay if you experience any of the following:
- Sudden worsening of vision: Any sudden decrease in your ability to see.
- Increased eye pain or redness: If your eye pain becomes severe or the redness increases significantly.
- New or worsening swelling around the eye: Any new puffiness or increase in existing swelling.
- Fever or chills: These could indicate a systemic reaction or other infection.
