This veterinary tablet helps control intestinal worms and prevent heartworm in dogs. It combines two proven actives to broaden parasite protection. This page explains how the treatment works, who it suits, and how to use it safely.
What Milbemax Is and How It Works
Milbemax 12.5 is a broad-spectrum deworming tablet for dogs, available with US delivery from Canada, and often purchased without insurance. CanadianInsulin.com is a prescription referral platform. We verify prescriptions with your prescriber when required, and licensed Canadian pharmacies dispense your order.
The medicine contains milbemycin oxime and praziquantel. Milbemycin affects parasite nerve transmission, which can kill immature heartworm and common intestinal roundworms and hookworms. Praziquantel disrupts tapeworm integrity, leading to rapid removal. Together, the combination treats and controls intestinal worms and, when given on a regular schedule, helps prevent heartworm disease as directed by the label.
Use follows veterinary guidance. Your prescriber selects the correct tablet count based on weight. Many dogs accept the flavored tablet, which simplifies administration.
Who It’s For
This treatment is for dogs when a veterinarian recommends control of intestinal worms and heartworm prevention. Puppies must meet the labeled age and weight before starting. Do not use in dogs with known hypersensitivity to any component. Use caution in herding breeds with MDR1 gene variants. Pregnant or lactating dogs should only receive this therapy if a veterinarian determines it is appropriate for the animal’s condition.
Dosage and Usage
Dosing is weight-based. Your prescriber will advise the tablet count and schedule. For intestinal worms, a single dose may be used per label. For heartworm prevention, monthly administration is typical during mosquito season, continuing on the schedule your veterinarian recommends. Offer with a small meal to reduce stomach upset. Ensure your dog swallows the full dose. If a tablet is spit out, give another only after your prescriber’s guidance.
Check the weight-band chart specific to Milbemax 12.5 before dosing. Keep a log of doses and set reminders. If your dog is on multiple parasite preventives, confirm overlapping coverage and timing with your veterinarian to avoid duplication.
Strengths and Forms
The product is available as flavored tablets for dogs. Common dog presentations include:
- Milbemycin oxime 12.5 mg praziquantel 125 mg tablets for larger weight bands
- A smaller tablet size for puppies and small dogs, selected by your prescriber
Availability may vary by supplier and season.
Missed Dose and Timing
If you miss a monthly heartworm preventive dose, give it as soon as you remember, then resume the usual monthly schedule. If the gap is substantial, your veterinarian may recommend testing before continuing. For intestinal worm treatment, give the dose when noticed and speak with your clinic about any follow-up. If vomiting occurs shortly after dosing, contact your veterinarian for advice before redosing. Keep Milbemax 12.5 on a consistent calendar to maintain coverage.
Storage and Travel Basics
Store tablets in the original blister and carton. Keep them dry, at room temperature, and away from direct light. Do not store near food or treats to prevent accidental ingestion. Keep out of reach of children and animals. When traveling, carry the original package and the prescription label. Place the carton in a secure pouch within your luggage. If crossing borders, bring a copy of veterinary documentation. Avoid excess heat in cars. Do not split or crush unless your prescriber directs you to do so.
Benefits
This combination therapy treats multiple intestinal worms in one dose. Regular use as directed helps prevent heartworm disease. A flavored tablet can improve acceptance in many dogs. Using a single product to cover several parasites can simplify monthly routines compared with multiple single-agent products.
Side Effects and Safety
- Digestive upset: vomiting, soft stool, or diarrhea
- Reduced appetite or drooling
- Lethargy or tiredness
- Transient incoordination or tremor in sensitive dogs
- Itching or mild skin reactions
Serious reactions are uncommon, but neurologic signs can occur in susceptible dogs. Overdose may increase risk of central nervous system effects. Dogs with high circulating microfilariae may show reactions when starting a macrocyclic lactone. Seek veterinary care if severe vomiting, persistent neurologic signs, difficulty breathing, or collapse occurs.
Drug Interactions and Cautions
Tell your veterinarian about all medicines, supplements, and parasite preventives your dog receives. Caution is warranted with other macrocyclic lactones, certain topical parasiticides, and drugs that affect P-glycoprotein transport. Steroids or other immunomodulators may complicate parasite evaluations. Do not combine overlapping wormers unless your veterinarian advises. Heartworm-positive dogs require a tailored management plan; do not start or resume preventive therapy without professional guidance.
What to Expect Over Time
After dosing, dead or dying intestinal parasites may be cleared by normal digestion. You may not always see worms pass in stool. With monthly prevention, your veterinarian may recommend annual or periodic testing for heartworm. Consistent administration, weight-appropriate dosing, and timely refills help maintain broad coverage. If your dog’s weight changes, ask whether a new tablet size is needed.
Compare With Alternatives
Some owners consider combination preventives and stand-alone wormers. Interceptor Plus treats common intestinal worms and prevents heartworm in dogs; compare with Interceptor Plus to see weight ranges and convenience features. For a heartworm-focused option, many veterinarians also recommend ivermectin-based preventives; see Heartgard for a monthly chew that targets heartworm larvae.
Pricing and Access
Use Canadian pricing to manage out-of-pocket costs while your order Ships from Canada to US. See current pricing on this page, then compare per-tablet value against your clinic’s options. Savings vary by quantity and weight band. Encrypted checkout protects your information. For occasional coupons, visit our Promotions page. If you have questions about coverage or reimbursement, ask your veterinarian or insurer for guidance. Keep refill reminders to avoid gaps in prevention. You can review Milbemax 12.5 listings and select the right presentation for your dog’s weight.
Availability and Substitutions
Supply can vary by season. If your preferred tablet count is unavailable, your prescriber may recommend a suitable alternative class with comparable spectrum. Do not switch products without veterinary advice, especially if heartworm prevention is needed. When used consistently and as directed, Milbemax 12.5 fits many canine parasite control plans set by veterinarians.
Patient Suitability and Cost-Saving Tips
This therapy may suit dogs needing both intestinal worm control and heartworm prevention. It may not suit dogs with known sensitivities or those outside labeled age or weight ranges. Ask about multi-month fills to reduce per-dose pricing and simplify scheduling. Set calendar alerts for monthly doses. Combine routine parasite checks with wellness visits to ensure the plan remains appropriate as your dog grows.

Does this product prevent both heartworm and intestinal worms?
Yes. Milbemax contains two active ingredients that cover common canine intestinal worms and provide heartworm prevention when used on the labeled schedule. Your veterinarian evaluates regional risks and your dog’s history before recommending the spectrum. Regular testing remains important for heartworm screening. Always follow the instructions on the package insert and your veterinarian’s guidance for dosing and duration.
How should I give the tablet to my dog?
Offer the dose with a small meal to reduce stomach upset. Many dogs accept the flavored tablet readily; if needed, place it deep on the tongue to ensure swallowing. Do not crush or split unless your veterinarian advises. If the tablet is expelled, ask your clinic before re-dosing. Keep a simple log so you can track each administration and avoid accidental extra doses.
What if I miss a monthly preventive dose?
Give the missed dose as soon as you remember, then continue the monthly schedule. If the lapse is significant, your veterinarian may recommend heartworm testing before continuing. Avoid stacking doses too closely without professional advice. Set calendar reminders or use a refill service to maintain consistent coverage throughout the mosquito season and any period your clinician recommends.
Can puppies use this medicine?
Puppies must meet the labeled age and weight requirements before starting. Your veterinarian selects the appropriate tablet size for growing dogs and may adjust as weight changes. For very young or underweight animals, other options may be considered until the puppy reaches the necessary threshold. Never guess a dose based on size alone; use a current weight from a recent clinic visit.
Does it treat tapeworms acquired from fleas or prey?
The combination includes an agent effective against tapeworms. Flea exposure and hunting behavior can increase tapeworm risk. Your veterinarian may also recommend year-round flea control to reduce reinfection pressure. For more on this topic, see our Tapeworm Treatment article for general education, then discuss a complete parasite plan suited to your dog’s habits and environment.
Can I use it with flea and tick preventives?
Many dogs receive a separate flea and tick product alongside heartworm and deworming tablets. Combinations vary by active ingredients. Provide your veterinarian with a full list of preventives and medicines to avoid overlapping classes or interactions. If your dog is sensitive to macrocyclic lactones or has a history of neurologic signs, ask about alternatives or staggered dosing plans.
What side effects should I watch for after dosing?
Mild digestive upset, drooling, or brief lethargy may occur. Less commonly, sensitive dogs can show incoordination or tremors. If severe vomiting, persistent neurologic signs, or collapse occurs, seek veterinary care. Keep tablets out of reach to prevent accidental ingestion, especially in multi-pet homes. Report any adverse events to your veterinarian, who can document the reaction and advise on future parasite control plans.
