What Is Albendazole?
Albendazole is a broad-spectrum benzimidazole anthelmintic widely used in veterinary parasite control programs for ruminants and other species under veterinary direction. On this page we focus on the liquid suspension your calculator uses: Albendazole 11.36% (≈113.6 mg/mL).
Drug Class: Benzimidazole Anthelmintic
- Family: Benzimidazoles (same class as fenbendazole, oxfendazole).
- Typical targets: gastrointestinal nematodes (roundworms; e.g., Haemonchus, Ostertagia/Teladorsagia, Trichostrongylus, Cooperia) and, depending on species/label/dose, certain cestodes (tapeworms) and trematodes (flukes).
- Use context: often part of a rotation strategy with other classes (macrocyclic lactones, tetrahydropyrimidines) to help manage resistance.
How It Works (Mechanism of Action)
MoA snapshot: Albendazole binds to β-tubulin in susceptible parasites → inhibits microtubule formation → disrupts glucose uptake and intracellular transport → energy depletion → death of susceptible stages.
Ovicidal activity (action on eggs) is noted in some species/parasites.
- Microtubule disruption impairs nutrient absorption and cellular division within the parasite.
- Effectiveness depends on parasite species, life stage, dose, and exposure time.
Formulations & Strengths (What This Calculator Uses)
- Albendazole 11.36% liquid suspension — concentration ≈ 113.6 mg/mL (this is the default for all calculator outputs on this page).
- Other forms (context only): pastes/suspensions in various strengths and solid tablets (not the focus here). Always follow the label and your veterinarian’s direction for the specific product you are using.
Dose math reminder:mL per dose = (Weight × mg/kg) ÷ 113.6. The calculator above performs this automatically and can total bottles for groups/herds.
Absorption & Practical Use Notes
- With feed/fat: In many species, administering with a small meal (dietary fat present) can increase oral bioavailability versus dosing on an empty stomach. Follow your veterinarian’s guidance for your species and situation.
- Ruminants vs. monogastrics: Rumen retention can prolong exposure in cattle/sheep/goats, while monogastrics (e.g., pigs, dogs) rely more on gastric/intestinal absorption. Practical protocols differ by species and target parasite.
- Active metabolite: Albendazole is metabolized to albendazole sulfoxide, which contributes to anthelmintic activity. Duration and levels vary with species, diet, and health status.
- Program design matters: Efficacy is influenced by accurate weight-based dosing, treatment timing, and follow-up (e.g., fecal egg count reduction tests). Integration with pasture hygiene and rotation helps manage resistance.

When to Use Albendazole (and When Not To)
Albendazole 11.36% is commonly used in veterinary parasite-control programs under a veterinarian’s direction. Choosing the right cases—and avoiding the wrong ones—improves outcomes and helps limit resistance.
Common Targets: GI Nematodes
- Gastrointestinal roundworms such as Haemonchus, Ostertagia/Teladorsagia, Trichostrongylus, Cooperia, and related strongyles (species- and region-dependent).
- Effectiveness varies with species, life stage, dose, and exposure time; confirm with your veterinarian and follow the product label for your market.
What About Tapeworms & Liver Flukes?
- Cestodes (tapeworms) and trematodes (liver flukes): Albendazole use is species- and dose-dependent, and label permissions vary by country/region. In some markets and species, labels include certain cestodes and/or flukes at specific doses; in others, they do not. Always check your local label and consult your veterinarian.
- If tapeworm coverage is needed in small animals, a dedicated tapeworm agent like Praziquantel is typically selected. See our Flea + Tapeworm Defense Pack.
Not for Ectoparasites (Fleas/Ticks)
Albendazole does not address external parasites such as fleas or ticks. For rapid flea knockdown, use a targeted product like Nitenpyram Flea Shield Max 5% or the Flea + Tapeworm Defense Pack.
Use in a Rotation Strategy
- In many programs, albendazole (a benzimidazole) is one pillar of a multi-drug rotation alongside other classes such as fenbendazole (benzimidazole), pyrantel (tetrahydropyrimidine), and ivermectin (macrocyclic lactone), as directed by your veterinarian.
- Fecal Egg Count Reduction Testing (FECRT): Verify efficacy 10–14 days post-treatment to guide future choices and detect resistance trends.
- Accurate weight-based dosing, treatment timing, and pasture/housing hygiene are critical components of any rotation plan.
Safety, Contraindications & Legal Notes
Albendazole is widely used in veterinary medicine, but it is not appropriate for every animal or every situation. Review the considerations below and consult your veterinarian before use.
Key Cautions
- Gestation: Avoid use during early pregnancy/first trimester unless your veterinarian specifically recommends it.
- Dairy/lactation:Withdrawal and milk-discard times vary by species and product label. Follow the label and your veterinarian’s guidance for your jurisdiction.
- Young, debilitated, or stressed animals: Use caution; assess risk–benefit with your veterinarian.
Adverse Effects (Generally Uncommon)
- Gastrointestinal upset (transient) may occur.
- With prolonged/high-dose courses in some species, bone marrow suppression has been reported; monitoring may be indicated in vet-directed protocols.
- Cats are especially sensitive; albendazole is generally not recommended in felines except under direct veterinary supervision. Alternatives are typically preferred.
Residues: Withdrawal & Milk Discard
Legal slaughter and milk withdrawal times are species- and label-specific. Regulations can change.
Regulatory & Use Context
- Label vs. extra-label: Use exactly as labeled for your product and market. Any extra-label use must be veterinarian-directed and compliant with local regulations.
- Keep batch numbers and dosing logs; integrate with fecal testing to document outcomes.
Banner Disclaimer: For animal use only. Not for human use. This page is educational and not a substitute for veterinary care.
Always follow your product label and your veterinarian’s instructions, including legal withdrawal times for meat and milk.
Dosing Principles (Calculator Explained)
The calculator converts your animal’s weight and the veterinarian/label dose (mg/kg) into a precise mL volume for Albendazole 11.36% (113.6 mg/mL). Accurate weight-based dosing is essential to efficacy and resistance management.
How the Calculator Works
Formula: mL per dose = (Weight × mg/kg) ÷ 113.6
- Weight can be entered in kg or lb (the tool converts lb → kg automatically).
- mg/kg is set by your veterinarian/label for the species and target parasite.
- 113.6 is the concentration (mg/mL) of Albendazole 11.36%.
1000 lb (~453.6 kg) animal at 7.5 mg/kg → (453.6 × 7.5) ÷ 113.6 ≈ 29.9 mL.
Species-Specific Doses & Schedules
Albendazole dose rates and schedules vary by species, parasite, and local label. Use the species tabs/sections on this page for typical ranges and program notes (to be completed after validation):
- Cattle, Sheep, Goats, Camelids: GI nematodes are the usual target; dose rates and any fluke/tapeworm indications depend on label and region.
- Swine, Horses, Dogs, Cats: Albendazole use may be limited or extra-label; cats are especially sensitive. Always consult your veterinarian.
Multi-day protocols: Some indications use repeated dosing (e.g., certain GI parasites or vet-directed regimens). The calculator supports scheduling but timing must follow your veterinarian/label.
Feeding & Administration
- Shake well before use; this is a suspension.
- Monogastrics (e.g., pigs, dogs): giving with a small meal (dietary fat present) can increase oral bioavailability. Follow your veterinarian’s guidance.
- Ruminants (cattle, sheep, goats, camelids): protocols may differ (e.g., rumen retention considerations). Any fasting approaches should be vet-directed only.
- Measure precisely using an oral dosing syringe or drench gun. Avoid under-dosing; if rounding, round conservatively upward within safe limits advised by your vet.
Record-Keeping & Follow-Up
- Log animal ID, weight, mg/kg, mL given, date, and product lot/batch (use the printable dose log above).
- Perform a Fecal Egg Count Reduction Test (FECRT) about 10–14 days post-treatment to confirm efficacy and guide rotation decisions.
- Integrate with pasture/housing hygiene (manure removal, rotation, stocking density) to reduce re-exposure.
Herd/Batch Planning
- The calculator can total mL for multiple animals and estimate bottles needed (4 oz ≈ 118.29 mL; 8 oz ≈ 236.59 mL; 32 oz ≈ 946.35 mL).
- Keep spare volume for spills and syringe dead-space; never dilute unless your veterinarian instructs.

Horses
Use Caution / Label Context
Albendazole is not commonly used or labeled for routine equine deworming in the U.S. Under veterinary guidance,
programs typically favor fenbendazole, pyrantel, and ivermectin (and, where appropriate, moxidectin). If albendazole is considered,
treat it as extra-label and proceed only with a veterinarian’s direction, including pregnancy cautions and any residue considerations.
fenbendazole/pyrantel/ivermectin (and pasture management) is preferred.
Targets & Patterns (General Guidance)
- Equine programs focus on strongyles, ascarids (young horses), and seasonal bots—addressed by standard equine actives under vet guidance.
- FECRT and targeted selective treatment (based on shedding status) are recommended to manage resistance.
Safety
- Pregnancy: Avoid during early gestation unless your veterinarian specifically recommends.
- Foals/compromised horses: Dose only under direct veterinary guidance.

Compliance & Safety: For animal use only. Not for human use. This content is educational and not a substitute for veterinary care.
Resistance Management (Must-Read)
Anthelmintic resistance is a growing challenge across species—especially in small ruminants and camelids. The most effective programs combine
diagnostics (FEC/FECRT), accurate dosing, drug-class rotation, and pasture/housing hygiene.
Use the principles below with your veterinarian to protect efficacy over time.
FEC / FAMACHA® Basics & Selective Treatment
- Fecal Egg Count (FEC): Lab or in-clinic microscopy that estimates eggs per gram (EPG). Use baseline FECs to understand herd burden and decide whether to treat.
- Targeted Selective Treatment (TST): Treat the individuals that need it (high shedders, clinical signs) rather than blanket-treating the whole group—reduces selection pressure.
- FAMACHA® (small ruminants): Conjunctival color scoring for Haemonchus-associated anemia; combine with FECs and body condition, not as a stand-alone decision tool.
How to Run a FECRT (Fecal Egg Count Reduction Test)
- Day 0: Collect pre-treatment FECs on a representative subset (e.g., 10–15 animals).
- Treat: Dose accurately by weight with the chosen drug/class.
- Day 10–14: Collect post-treatment FECs from the same animals.
Calculate reduction:FECR% = ((Pre − Post) ÷ Pre) × 100. Your veterinarian will interpret thresholds (e.g., <95% reduction may suggest reduced susceptibility) and advise next steps.
Rotate Drug Classes Strategically
Use distinct classes to limit selection pressure. Coordinate rotation with FEC/FECRT results and your local risk calendar.
| Drug Class | Examples | Typical Targets* | Notes |
|---|---|---|---|
| Benzimidazoles | Albendazole, Fenbendazole | GI nematodes; label-dependent tapeworm/fluke contexts | Resistance common in small ruminants—verify with FECRT. |
| Tetrahydropyrimidines | Pyrantel | GI nematodes (equine/companion protocols) | Useful partner in rotations; species-specific dosing. |
| Macrocyclic lactones | Ivermectin, Moxidectin | GI nematodes; certain ectoparasites (class-specific) | Potent, but resistance emerging—use judiciously. |
| Isoquinolines | Praziquantel | Tapeworms (cestodes) | Not a nematode drug; pair when tapeworms are confirmed/suspected. |
*Targets vary by species, label, and region. Always follow your veterinarian’s direction and the current product label.
Avoid Under-Dosing (Top Resistance Driver)
- Weigh accurately: Use a scale when possible. If estimating, use a weigh tape and build in a safety margin per vet guidance.
- Calibrate equipment: Check drench guns/syringes for accuracy; replace worn seals; shake suspensions thoroughly.
- Group dosing: Dose to the heaviest animal in a group (within reason) when animals are similar in size—your vet can advise.
- Complete schedules: If a protocol calls for repeats (multi-day or re-dose), keep to the timetable; skipping doses reduces efficacy.
Pasture & Housing Hygiene
- Manure management: Prompt removal in pens/stalls; compost away from traffic areas.
- Rest/rotation: Rotate pastures to interrupt life cycles; avoid over-grazing and high stocking density.
- Mixed classes/age groups: Separate high-risk (young, periparturient) from adults where practical.
- Water & feed: Keep troughs elevated/clean; minimize fecal contamination of feeding areas.

Side Effects & Troubleshooting
What to Watch For
- Common, usually mild: transient GI upset (soft stool, decreased appetite), lethargy.
- Less common but important: hypersalivation, ataxia/weakness, jaundice, pale mucous membranes, hives/swelling, collapse.
- Cats & high/prolonged dosing (any species): increased risk for adverse effects; cats are especially sensitive. Use only under veterinary supervision.
Stop & Call Your Veterinarian If:
- Severe vomiting/diarrhea, dehydration, neurologic signs, collapse, or allergic reactions (hives/face swelling/difficulty breathing).
- Anorexia > 24 hours, bloody stool, or yellow gums/eyes (possible liver involvement).
- You suspect an overdose or the wrong concentration was used.
Troubleshooting Poor Response
- Re-check the math: correct product concentration (11.36% = 113.6 mg/mL), weight units (lb vs kg), and mg/kg.
- Weigh accurately: under-dosing is a top driver of resistance; dose to actual weight (or heaviest in group, per vet).
- Shake suspension & calibrate equipment: worn drench guns/syringes mis-dose; replace seals, verify volumes.
- Verify schedule: some indications require multi-day or repeat dosing—don’t skip the re-dose window if prescribed.
- Run a FECRT: repeat fecal egg counts 10–14 days post-treatment; <95% reduction may indicate reduced susceptibility (vet to interpret).
- Consider re-exposure: update pasture/housing hygiene; separate high-shedders; review stocking density and sanitation.
- Rotate classes: if response is inadequate, your vet may switch to another class (e.g., macrocyclic lactone or tetrahydropyrimidine).
Safety: For animal use only. Not for human use. Use under veterinary guidance; follow label directions and legal withdrawal times.
Pairing & Alternatives
Albendazole is one tool in a comprehensive parasite program. Depending on species, parasite mix, and FECRT results, your veterinarian may prefer or pair other classes.
When to Prefer Another Class
- Routine puppies/kittens: Often start with Pyrantel 5% and/or Fenbendazole. See the Puppy & Kitten Starter Pack.
- Equine programs: Typically rely on Fenbendazole, Pyrantel, and Ivermectin (vet-directed). See the Horse Wormer Rotation Pack.
- Tapeworm-specific: Use Praziquantel 5% or the Flea + Tapeworm Defense Pack (when flea-associated tapeworms are suspected).
- Suspected benzimidazole resistance: Your vet may rotate to a macrocyclic lactone (e.g., ivermectin) or a tetrahydropyrimidine (pyrantel), informed by FECRT.

FAQs
Is albendazole safe for pregnant animals?
Use caution. In many programs, albendazole is avoided during early pregnancy/first trimester unless a veterinarian specifically recommends it. Safety depends on species, dose, timing of gestation, and local label restrictions.
- Ruminants (cattle, sheep, goats, camelids): consult your veterinarian before use in bred animals. Labels and withdrawal requirements vary by market.
- Horses: albendazole is not commonly used/labeled for routine equine deworming in the U.S.; discuss alternatives (fenbendazole/pyrantel/ivermectin/moxidectin) with your vet.
- Dogs & cats: any use is veterinarian-directed; cats are especially sensitive and albendazole is generally not recommended.
Always follow your product label and veterinarian’s instructions, including legal withdrawal times for meat and milk.

FAQs
What parasites does albendazole treat in goats/cattle/sheep?
Albendazole is used (per label/vet direction) to help manage GI nematodes such as Haemonchus, Ostertagia/Teladorsagia, Trichostrongylus, and Cooperia. Coverage for tapeworms and liver flukes is species- and dose-dependent and varies by region/label. Always confirm locally with your veterinarian.
See species guidance: Goats • Sheep • Cattle and When to Use Albendazole.
Albendazole vs fenbendazole — what’s the difference?
Both are benzimidazoles with similar mechanisms (β-tubulin binding → microtubule disruption). Practical differences are often about species labels, dosing ranges, safety margins, and resistance patterns in your area. Many programs use fenbendazole for routine needs (e.g., dogs, horses) and reserve albendazole for vet-directed scenarios in ruminants or specific targets.

Can I give albendazole to dogs or cats?
Dogs: use is typically off-label and only under veterinary supervision (e.g., certain GI nematodes; some Giardia protocols). For routine canine deworming, vets commonly prefer Fenbendazole and/or Pyrantel 5%.
Cats: albendazole is generally not recommended due to toxicity risk. Tapeworms are usually addressed with Praziquantel 5%; flea control with Nitenpyram. See Dogs and Cats (caution).
Bundle option: Flea + Tapeworm Defense Pack.
How soon can I butcher after albendazole?
Withdrawal times are species-, indication-, and label-specific and vary by jurisdiction. Always verify with your current product label and veterinarian before slaughter.
See: Withdrawal Times & Milk Discard (table placeholder for your market).
Does albendazole cover tapeworms or liver flukes?
It can in some species/dose/labels, but this varies by region. For tapeworms in small animals, a dedicated agent like Praziquantel 5% is typically preferred. Liver fluke indications (where allowed) are highly label-specific—confirm locally with your vet.

Why did my treatment “fail” — was it resistance or under-dosing?
Common reasons include under-dosing (wrong weight/units, equipment error), missed re-dose windows, re-exposure (pasture/housing hygiene), or parasite resistance. Run a FECRT 10–14 days post-treatment and talk to your vet about rotating drug classes.
See: Side Effects & Troubleshooting • Resistance Management • Alternatives: Ivermectin, Pyrantel, Fenbendazole.
Should I feed before dosing albendazole?
In many monogastrics, a small meal (with dietary fat) can improve oral bioavailability. Ruminant protocols differ (rumen retention, fasting considerations) and should be vet-directed. Always follow your veterinarian’s guidance for your species and situation.
