What Interceptor Plus® Is and How It Works

Interceptor Plus is a veterinary prescription preventive for dogs. It combines milbemycin oxime and praziquantel in one chewable tablet. Milbemycin blocks the development of heartworm larvae transmitted by mosquitoes. It also treats and controls adult hookworms, roundworms, and whipworms. Praziquantel targets adult tapeworms. Together, these ingredients provide broad internal parasite coverage in one monthly dose. This product ships from Canada with US delivery.

Tapeworms are common in dogs that hunt or ingest fleas. For background reading, see our guide on Effective Tapeworm Treatment.

Who Interceptor Plus® Is For

Interceptor Plus is for dogs eight weeks of age or older and weighing at least two pounds. It is for year-round heartworm prevention and control of common intestinal worms. It is not for cats or other species.

Do not use in dogs with a known hypersensitivity to milbemycin oxime or praziquantel. Use caution in dogs with a history of neurologic disorders. Safety in breeding, pregnant, or lactating dogs has not been fully established. Discuss use in these situations with your veterinarian.

Dosage and Usage

Give one chewable tablet by mouth once every month. Select the tablet strength that matches your dog’s weight band. If your dog is over the top weight band, your veterinarian may direct you to combine tablets.

Begin year-round prevention as recommended by your veterinarian. Test for heartworm infection before starting a preventive. Give tablets on the same date each month to maintain coverage. You may give with or without food. Chewables are palatable, but ensure your dog consumes the full dose.

If your household uses multiple preventives, keep a written schedule. Ask your clinic to align monthly timing with your dog’s vet visits when possible.

Strengths and Forms

Interceptor Plus is available as flavored chewable tablets in weight-based strengths for dogs:

• 2 to 8 lb
• 8.1 to 25 lb
• 25.1 to 50 lb
• 50.1 to 100 lb

Availability may vary by strength. Your veterinarian will specify the correct tablet for your dog’s weight.

Missed Dose and Timing

If you miss a monthly dose, give the tablet as soon as you remember. Then resume your regular monthly schedule. If more than one month has passed, talk with your veterinarian. A heartworm test may be recommended before restarting. Try to set phone reminders or calendar alerts to reduce missed doses.

Storage and Travel Basics

Store chewable tablets at room temperature. Keep them in the original blister until use. Protect from moisture and light. Keep out of reach of children and other animals.

When you travel, pack your dog’s dose in a carry-on bag. Keep the box or a photo of the label with the prescription details. You can order refills online for US delivery from Canada while you are away.

Benefits

Interceptor Plus protects against heartworm disease when given monthly. It treats and controls adult roundworms, hookworms, whipworms, and tapeworms. One chewable simplifies parasite protection. Weight-banded dosing helps ensure your dog receives an appropriate amount. The tablet is flavored for easier administration.

Broad parasite control reduces separate deworming visits for many dogs. Your veterinarian may still recommend a dedicated flea or tick product. Interceptor Plus does not kill fleas or ticks.

Side Effects and Safety

• Vomiting
• Diarrhea or soft stools
• Lethargy
• Decreased appetite
• Itching

Serious or rare reactions may include neurologic signs such as tremors, incoordination, or seizures. Dogs with a heavy existing worm burden may show digestive upset as parasites clear. Contact your veterinarian if symptoms are severe or persistent, or if your dog ingests multiple tablets.

Risk of low blood sugar is not associated with this medication. However, observe dogs closely the first time they receive any new preventive.

Drug Interactions and Cautions

Tell your veterinarian about all products your dog takes. This includes other heartworm preventives, flea and tick treatments, and any supplements. Use caution when combining with other macrocyclic lactones. Discuss potential interactions with drugs that can affect P-glycoprotein or liver enzymes, such as certain azole antifungals or macrolide antibiotics. Do not change doses or stop prescription medicines without veterinary guidance.

What to Expect Over Time

Most dogs tolerate the chewable well. After the first few months, monthly dosing becomes a routine. Regular use reduces the risk of heartworm disease and controls common intestinal worms. Your veterinarian may recommend periodic fecal testing and annual heartworm testing.

Compare With Alternatives

Several FDA-approved preventives protect dogs from heartworm and intestinal worms. Heartgard® uses ivermectin for heartworm prevention and includes pyrantel for certain intestinal worms. It does not treat tapeworms. Proheart® 6 is an injectable moxidectin preventive given by a veterinarian every six months. Your clinic can help choose the best option for your dog’s lifestyle.

Availability and Substitutions

If a specific strength is temporarily unavailable, your prescriber may recommend an alternative. For tapeworm-only treatment, your clinic may suggest a separate dewormer such as Drontal® Plus or Droncit®. Always follow your veterinarian’s guidance when switching products.

Patient Suitability and Cost Saving Tips

Good candidates include dogs in heartworm areas or dogs that travel with owners. Dogs at risk for intestinal parasites also benefit, including outdoor and hunting dogs. Avoid use in dogs with known allergies to components. Discuss use if your dog is pregnant, nursing, or used for breeding.

To save, consider multi-month supplies if your prescription allows. Set refill reminders so you never miss a month. For complete coverage, pair a flea and tick product with your heartworm preventive. A common choice is Simparica® for flea and tick control, used alongside your monthly heartworm product as directed by your veterinarian.
