The deworming went fine. Your pediatrician treated the whole household for pinworm, everyone finished their course, and now there are three white tablets left in the bottle on the kitchen counter. Do you keep them for next time? Toss them in the trash? Flush them? This handbook walks through how to store and dispose of albendazole the right way, room by room, from the medicine cabinet to the car to the drop-off kiosk at your pharmacy.
Safety note: This guide is educational and doesn’t replace advice from your prescriber or pharmacist. Always follow the label that came with your specific albendazole product. If someone swallowed tablets that weren’t prescribed for them, call Poison Control at 1-800-222-1222 or, for collapse, seizures, or trouble breathing, call 911.
The Short Version
- Storage temperature: The U.S. label says to keep albendazole at 20°C to 25°C (68°F to 77°F), in a tightly closed, light-resistant container.
- Best spot at home: A cool, dry, high cabinet or locked box. Not the bathroom, not a sunny windowsill, not the kitchen counter.
- Children: Use the child-resistant cap every time, and remember that “child-resistant” doesn’t mean childproof.
- Leftovers: Don’t save them for a future infection. A new problem needs a new evaluation.
- Disposal order: Drug take-back site or kiosk first, mail-back envelope second, household trash method third.
- Never flush: Albendazole is not on the FDA flush list.
Why It Pays to Store and Dispose of Albendazole Correctly
Albendazole is a prescription anthelmintic, meaning a medicine that kills parasitic worms. In the U.S., the FDA has approved it for two serious tapeworm-larva infections (neurocysticercosis and hydatid disease), and doctors also prescribe it for several intestinal worm infections. You can read the full list of approved and common uses in our guide to albendazole uses.
Because courses are often short, many households end up with a few spare tablets. That creates two problems. First, a stored tablet can lose strength if heat or moisture gets to it. Second, an unused tablet sitting in a drawer is a temptation, both for a curious toddler and for an adult who wonders if that new stomach upset is “worms again.”
When you store and dispose of albendazole properly, you solve both problems at once. Your current course stays effective, and leftovers leave the house safely.
What the Label Actually Says About Storage
The prescribing information for U.S. albendazole tablets, posted on DailyMed, gives a short but specific set of instructions. Here’s what it covers and what it means in everyday terms.
| Label instruction | What it means at home |
|---|---|
| Store at 20°C to 25°C (68°F to 77°F) | Normal indoor room temperature. Avoid spots that get hot or cold. |
| Keep in a tight container | Close the cap firmly after every use so humid air can’t get in. |
| Keep in a light-resistant container | Leave the tablets in the original amber or opaque bottle or blister pack. |
| Keep out of reach of children | Store up high, ideally locked, and out of sight. |
| Child-resistant closure (on supplied bottles) | Click the cap shut fully, even if you’ll take the next dose in a few hours. |
MedlinePlus, the National Library of Medicine’s consumer drug guide, adds practical detail. It advises keeping albendazole in its original container, tightly closed, at room temperature, and away from excess heat and moisture. It also specifically says not to store it in the bathroom.
What about chewable albendazole tablets?
Some albendazole products come as chewable tablets, and many international deworming programs use a 400 mg chewable form. Chewables tend to be more sensitive to moisture because they’re designed to break apart easily. The Cleveland Clinic’s consumer sheet for the chewable tablet lists the same 20°C to 25°C range and stresses keeping the container closed tightly.
Labels outside the U.S. can differ. For example, one WHO-prequalified 400 mg albendazole tablet made for tropical markets is labeled to be stored below 30°C, and its bottles are meant to be discarded 30 days after first opening. That’s a good reminder: your own box or pharmacy label is the instruction that counts. If two sources disagree, follow the label on your product and ask your pharmacist.
Room by Room: Where to Keep Albendazole at Home
Most homes have a “medicine spot” chosen by habit. Here’s how the usual suspects rate.
The bathroom: skip it
The bathroom cabinet is the classic medicine cabinet, but it’s one of the worst places for tablets. Hot showers push humidity and temperature up and down several times a day. Over weeks, that moisture can soften film coatings, make chewables crumbly, and speed up chemical breakdown. MedlinePlus specifically tells people not to store albendazole there.
The kitchen: choose carefully
The kitchen can work, but placement matters. The cabinet above the stove or next to the dishwasher gets steam and heat. The counter by the coffee maker is in plain view of kids. A high cabinet away from the stove, sink, and windows is a better choice, especially if you keep a small lockable box inside it.
Pairing the bottle with mealtimes can also help you remember doses, since the U.S. label tells people to take albendazole tablets with food. For more on why, see our explainer on taking albendazole with food.
The bedroom: good, with conditions
A bedroom closet shelf or a dresser drawer is usually cool, dry, and dark, which suits the label well. The catch is the nightstand. A bottle left next to the bed is easy for a visiting grandchild or a pet to reach. If you use the bedroom, go high and closed, not low and open.
Purses, backpacks, and pill organizers
Carrying a dose in a bag is convenient, but kids love to dig through bags, which makes them a common route to accidental ingestion. Weekly pill organizers also have no child-resistant feature and don’t protect from light or moisture. If you use one, keep it locked away and only load a day or two at a time.
| Spot | Rating | Main concern |
|---|---|---|
| Bathroom cabinet | Avoid | Humidity and temperature swings |
| Above the stove or dishwasher | Avoid | Heat and steam |
| Sunny windowsill or car dashboard | Avoid | Heat and light |
| High kitchen cabinet away from appliances | Good | Make sure it’s out of kids’ reach |
| Bedroom closet shelf | Good | Keep it high and closed |
| Locked medicine box in a cool room | Best | None, if you lock it every time |
| Purse, backpack, or open pill organizer | Use with care | Children and pets can reach it easily |
Storing Albendazole Around Children
Albendazole is often prescribed for children, and families are often treated together. That means pediatric-friendly tablets may be sitting in a home full of small hands. The stakes are real. A child who swallows extra tablets is getting a medicine at an unplanned amount, and albendazole can affect the liver and blood counts at higher exposures or over longer courses. You can read more about those effects in our guide to albendazole side effects.
Child-resistant is not childproof
Child-resistant caps are designed to slow children down, not to stop them completely. A determined preschooler can sometimes open one, especially if the cap wasn’t pushed down until it clicked. Use these habits:
- Re-lock the cap fully after every single dose, even if the next one is in a few hours.
- Put the bottle back in its storage spot right away instead of leaving it on the counter “for later.”
- Store medicine up high and out of sight, since kids climb to reach what they can see.
- Tell grandparents, babysitters, and visiting relatives where medicine is kept and ask them to secure their own purses and bags.
- Avoid calling medicine “candy,” even with a chewable tablet a child doesn’t want to take.
If a child swallows tablets that weren’t meant for them
Stay calm and act quickly. Call Poison Control at 1-800-222-1222 or use the online tool at poisonhelp.org. Experts answer 24 hours a day, free and confidential. Have the bottle in hand so you can tell them the strength and roughly how many tablets might be missing. If the child is unconscious, having a seizure, or struggling to breathe, call 911 right away.
Travel, Hot Cars, and Humid Climates
Albendazole is often prescribed around international travel, so travel storage deserves its own section.
Flights and road trips
Keep albendazole in your carry-on bag rather than in checked luggage. Cargo holds can get hot or cold, and lost bags happen. Keeping the original labeled pharmacy bottle also helps if anyone asks what the tablets are, and it keeps the light protection the label calls for.
The hot car problem
A parked car on a summer day can get far hotter than the 77°F upper limit on the label, and the glove box and dashboard are usually the worst spots. Don’t leave albendazole in the car while you run errands. If you’re on a road trip, bring the bottle into your hotel room or keep it in an insulated bag in the cabin, out of direct sun. Don’t put tablets directly on ice packs, since condensation can wet them.
Tropical and very humid places
In hot, humid climates, moisture is often a bigger threat than heat. A few simple steps help:
- Keep tablets sealed in the original blister pack or bottle until it’s time for a dose.
- Leave any desiccant packet that came in the bottle inside it. Don’t swallow it, and keep it away from kids.
- Store the bottle in an air-conditioned room if you have one.
- Don’t move tablets into a loose plastic bag or an open pill case.
- Buy medicine abroad only from licensed pharmacies, since counterfeit and substandard antiparasitic products are a known problem in some markets.
How to Tell If a Tablet Has Gone Bad
You can’t test a tablet’s strength at home. Still, physical changes can tell you that something went wrong in storage. U.S. albendazole 200 mg tablets are described in the label as white to off-white, round, and film-coated. Your product may look different, so compare against what the pharmacy label or leaflet describes.
Signs it’s time to stop using a tablet and talk to your pharmacist:
- Color changes, spots, or yellowing that weren’t there when you picked it up
- A coating that’s cracked, peeling, sticky, or soft
- Tablets that crumble, swell, or stick together
- An unusual or strong odor when you open the bottle
- Moisture or condensation inside the container
- Any tablet that’s past the expiration date on the label
If you notice any of these, don’t take the tablet “just to finish the course.” Call your pharmacy. They can often replace damaged medicine, and they’ll tell your prescriber if the course needs to be adjusted. If you’re mid-course and simply forgot a dose, our guide to a missed dose of albendazole explains what to discuss with your care team.
Expiration Dates and the Leftover-Tablet Trap
The expiration date marks the end of the period the manufacturer has shown the medicine will stay safe and effective when stored as directed. The FDA’s consumer guidance on why not to use expired medicines explains that medicines can lose strength or change chemically after that date. For a drug meant to clear an infection, a weaker dose can mean the infection doesn’t go away.
Why you shouldn’t save leftovers for “next time”
Even if your leftover albendazole is well within its date, using it on your own for a new problem is risky for several reasons:
- The diagnosis might be different. Itching, belly pain, or diarrhea can come from many causes besides worms. Our guide to symptoms of intestinal worms shows how much overlap there is with other conditions.
- The worm might be different. Albendazole works well against some parasites and less well against others. Some tapeworms and threadworms are usually treated with different first-choice drugs. Our walkthrough of albendazole for tapeworm and roundworm explains why.
- The dose and length of treatment vary. Courses can range from a single dose to weeks of treatment, and the label bases some dosing on weight. A prescriber chooses the amount and schedule for that person and that infection.
- The person might be different. A tablet prescribed for one family member may not be right for another, especially a young child, or someone who is pregnant, could become pregnant, or has liver disease. See our guide to albendazole during pregnancy and breastfeeding for why this matters.
- Monitoring may be needed. Longer courses often need blood tests to check the liver and blood counts. Self-treatment skips that safety step.
MedlinePlus states it plainly: don’t let anyone else take your medication. If symptoms come back, the right move is a fresh visit, which may include a stool test, rather than reaching for old tablets.
What if your doctor plans a repeat dose?
Sometimes a prescriber builds a second dose into the plan, such as for pinworm, where CDC guidance repeats treatment two weeks later because the drugs don’t kill eggs. In that case, the “leftover” tablet isn’t a leftover at all. Keep it stored properly, mark the date on your calendar, and take it only as directed. If you’re unsure whether a remaining tablet is part of the plan, call the pharmacy before throwing it out. Families who are treated on a set schedule can learn more in our article on deworming schedules.
The Disposal Ladder: How to Dispose of Albendazole Safely
When you’re truly finished with the medicine, think of disposal as a ladder. Start at the top rung and only move down if the option above isn’t available. This order follows the FDA’s guidance on where and how to dispose of unused medicines.
Rung 1: Drug take-back sites and events
The FDA calls take-back programs the best way to get rid of most unused or expired medicines. You have two main options.
National Prescription Drug Take Back Day. The DEA runs this event twice a year, typically in April and October, with thousands of temporary collection points at police stations, pharmacies, and community sites. It’s free and anonymous. You can find dates and nearby locations on the DEA Take Back Day page.
Year-round drop-off kiosks. You don’t have to wait for the event. Many retail pharmacies, hospitals, and police departments keep permanent drop boxes that accept prescription medicines any day they’re open. The DEA website also has a search tool for authorized collection sites, and your pharmacist can tell you the closest one.
Before you drop off the bottle, scratch out or peel off your name and prescription number.
Rung 2: Pharmacy mail-back envelopes
If getting to a drop-off site is hard, a prepaid drug mail-back envelope is the next best option. These are sold at many pharmacies and online, and some pharmacies hand them out free. You place the medicine inside, seal it, and mail it through the U.S. Postal Service. This is a great option for people with limited mobility or in rural areas.
Rung 3: The household trash method
If you can’t use take-back or mail-back, the FDA’s instructions for disposing of medicine in the trash apply to albendazole. Here are the steps, paraphrased:
- Take the tablets out of their original container.
- Mix them with something unappealing, like used coffee grounds, dirt, or cat litter. The FDA says not to crush the tablets.
- Put the mixture in a sealed container, such as a zipper bag or an empty can with a lid.
- Throw the sealed container in your household trash.
- Scratch out all personal information on the empty bottle’s label, then trash or recycle the bottle.
The point of the coffee grounds or litter is simple. It makes the medicine unattractive to children, pets, and anyone digging through the garbage.
What not to do: don’t flush it
The FDA keeps a short flush list of medicines that should be flushed when take-back isn’t available. These are mostly strong opioids and a few other drugs that could be deadly in a single accidental dose. Albendazole is not on that list. MedlinePlus also says not to flush albendazole down the toilet. Likewise, don’t pour crushed tablets down the sink.
| Option | Ranking | Best for |
|---|---|---|
| Year-round take-back kiosk | First choice | Anyone near a pharmacy, hospital, or police station with a drop box |
| DEA National Take Back Day | First choice | People who like an event reminder twice a year |
| Prepaid mail-back envelope | Second choice | Rural areas, limited mobility, or busy schedules |
| Household trash method | Third choice | When no take-back or mail-back option is available |
| Flushing or sink | Not recommended | Not for albendazole |
Why Disposal Matters for the Environment
Why does it matter where a few tablets end up? The FDA notes that most of the medicine traces found in waterways come from people’s bodies passing drugs through wastewater, not from flushing. Even so, there’s no reason to add more. Wastewater treatment plants aren’t designed to remove every drug compound, and antiparasitic medicines are biologically active by design.
Take-back programs generally send collected medicines for incineration under controlled conditions. That destroys the drug instead of sending it into soil or water. Choosing take-back is a small step that keeps medicine out of the environment and out of the wrong hands at the same time.
Accidental Ingestion by Pets
Albendazole is also used in veterinary medicine for some animals, but that doesn’t make a human tablet safe for your dog or cat. Pets are known for chewing through bottles and eating tablets dropped on the floor. Animal doses and safety limits are not the same as human ones, so a tablet sized for a person isn’t a safe guess for a pet.
If your pet eats albendazole or any other human medicine:
- Call your veterinarian or an emergency vet clinic right away.
- You can also call the ASPCA Animal Poison Control Center at (888) 426-4435, which is staffed around the clock. A consultation fee may apply.
- Have the bottle ready so you can share the strength and how many tablets might be missing.
- Don’t try to make your pet vomit unless a veterinary expert tells you to.
And never give your own albendazole to a pet with suspected worms; that plan should come from a vet.

FAQ: How to Store and Dispose of Albendazole
What temperature should albendazole be stored at?
The U.S. prescribing information says to store albendazole tablets at 20°C to 25°C, which is 68°F to 77°F. Keep them in a tightly closed, light-resistant container. Some products sold abroad have different labeled limits, so always check the label on your package.
Does albendazole need to be refrigerated?
No. The U.S. tablet label calls for normal room temperature storage, not refrigeration. Putting tablets in the fridge can expose them to condensation when you take them in and out. If you have a liquid or compounded product, ask your pharmacist, because those can have different instructions.
Can I flush albendazole down the toilet?
No. Albendazole is not on the FDA’s flush list, and MedlinePlus advises against flushing it. Use a take-back site or mail-back envelope. If neither is available, follow the FDA’s household trash method.
Can I keep leftover albendazole for the next time someone gets worms?
It’s not a good idea. A new set of symptoms may have a different cause or involve a parasite that needs a different drug or dose. The prescriber also has to consider the person’s age, weight, pregnancy status, and liver health. Have the person evaluated and get a fresh prescription if one is needed.
Is it safe to take albendazole after the expiration date?
The FDA advises against using expired medicines because they may be less effective or may have changed chemically. With an antiparasitic, reduced strength could mean the infection isn’t cleared. Dispose of expired tablets and contact your prescriber if you still need treatment.
Where can I drop off unused albendazole near me?
Ask your pharmacist first, since many pharmacies have year-round drop boxes. The DEA Take Back Day page lists collection sites during the spring and fall events, and the DEA also offers a year-round authorized collector search. Local police departments and hospitals often have kiosks too.
What should I do if my child swallowed albendazole?
Call Poison Control at 1-800-222-1222 right away, or use poisonhelp.org. Keep the bottle with you so you can give the strength and the possible number of tablets. If the child collapses, has a seizure, or has trouble breathing, call 911.
My dog ate an albendazole tablet. Is that dangerous?
It may be, depending on the amount and the animal. Call your veterinarian or the ASPCA Animal Poison Control Center at (888) 426-4435, which may charge a consultation fee. Don’t try to induce vomiting unless a professional tells you to.
Putting It Together
Albendazole doesn’t need special equipment, just steady habits. Keep it at normal room temperature, sealed in its original container, and stored high or locked away from children and pets. Keep it out of bathrooms and hot cars. When you’re done, don’t hold onto leftovers “just in case.” Bring them to a take-back kiosk or event, use a mail-back envelope, or follow the FDA trash method as a last resort.
Once you know how to store and dispose of albendazole, the same routine works for almost every medicine in your home. When in doubt, your pharmacist is the fastest, free source of answers about your specific product.
