    What is Iverhart Max?

    Iverhart Max prevents canine heartworm disease. It also treats and controls roundworms, hookworms, and tapeworms. Iverhart Max requires a prescription from your veterinarian.
    For: Dogs (8 weeks of age and weighing at least 6 lbs)
     
    Benefits:
    Tasty chewable tablets (pork liver cereal based with artificial beef)
    Easy to administer
    Given once a month

    How it works:
    Iverhart Max is an anthelminthic (dewormer). The ingredient pyrantel pamoate is used to treat and control roundworms and hookworms in dogs. Praziquantel is used for treating and controlling tapeworms.

    Studies have indicated that certain dogs of the herding breeds are more sensitive to the effects of ivermectin administered at elevated dose levels due to the MDR1 gene. For a full list of dog breeds that may be affected, click here.

    Cautions:
    Can cause sensitivities in herding dog breeds. Side effects of Iverhart Max are rare, but may include lethargy, limpness, salivation, shaking, diarrhea, decreased appetite, licking lips, and belching. Do not give Iverhart Max to your pet if already giving a different heartworm medication. The safe use of this drug has not been evaluated in pregnant or lactating bitches.


    More Information:
    Brand Name
    Iverhart Max (Virbac)
    Generic Name
    Ivermectin/Pyrantel Pamoate/Praziquantel (eye-ver-mekí-tin pie-raní-tell pamí-oh-ate prah-zee-kwaní-tell)

    What is the most important information I should know about Iverhart Max: Iverhart Max is a prescription medication available as chewable tablets in four strengths for dogs of different weights. Iverhart Max is packaged in boxes of 6 tablets and 12 tablets each tablet individually foil wrapped. It is important for the pet to consume the entire tablet. Iverhart Max should be used in dogs at least 8 weeks of age and no weight requirements. Iverhart Max is for use in dogs only.

    What is Iverhart Max: Ivermectin is an anthelminthic (dewormer) used for the prevention of heartworm disease in dogs. Pyrantel pamoate is used for treating and controlling roundworms and hookworms in dogs. Praziquantel is used for treating and controlling tapeworms. It is recommended that heartworm prevention is used year round.

    What should I discuss with my veterinarian before giving Iverhart Max to my pet: Tell your veterinarian if your pet has ever had an allergic reaction to the medication or any of it's individual ingredients.

    How should this medication be given: Use with caution, Collies and other herding dog breeds have been known to have adverse reactions to invermectin administered at elevated dose levels. Give Iverhart Max exactly as directed by the veterinarian. If you do not understand the directions ask the pharmacist or veterinarian to explain them to you. The usual dose of Iverhart Max in toy dogs 6 to 12 pounds is 34mcg/28.5mg/28.5mg (Magenta), for small dogs 12.1 to 25 pounds is 68mcg/57mg/57mg (Blue), for medium dogs 25.1 to 50 pounds is 136mcg/114mg/114mg (Green) and for large dogs 50.1 to 100 pounds is 272mcg/228mg/228mg (Brown). For dogs over 100 pounds the appropriate combination of strengths is used. Remove only one tablet at a time from the foil backed blister card. Iverhart Max can be given as a treat by hand or mixed with a small amount of food. Store the remainder in the original box they came in to protect from light. Store Iverhart Max at room temperature. Keep this medication out of the reach of children and pets. In addition, the safe use of this drug has not been evaluated in pregnant or lactating bitches.

    What happens if I miss giving a dose:Give the missed dose as soon as you remember. Do not give a double dose of the medication.

    What happens if I overdose the pet: Seek emergency veterinary medical treatment. Symptoms of overdose may include vomiting, diarrhea and incoordination.

    What should I avoid while giving Iverhart Max to my pet: If the dog has not taken heartworm preventative for 6 months or less, start the medication and test for heartworms after 6 months since microfilaria, that take 6 months to mature, will result in a positive heartworm test result. Because humans can contract hookworm and tapeworm from animals, it is important to maintain good personal hygiene. It is also important to eliminate fleas on the pet and in the household and to not feed the pet rodents. To prevent reinfection, daily cleanup of stools is recommended.

    What are the possible side effects of Iverhart Max: Side effects of Iverhart Max are rare but may include lethargy, limpness, salivation, shaking, diarrhea, decreased appetite, licking lips and belching.

    What other drugs will affect Iverhart Max: Do not give Iverhart Max to your pet if already taking an alternate heartworm medication.

    Where can I get more information: Your pharmacist has additional information about Iverhart Max written for health professionals that you may read.

    Easy and it Works My dog never gives me an issue when trying to give her Iverhart Max. Once a month and done. I visited the vet for her yearly (first year) checkup and she said all is great, no issues. As far as price, it's better than my vet could offer, so I will continue to purchase through 1-800-PetMeds 04/24/2014
    Iverhart Max Iverhart Max product review: As I also mention under my product review for Iverhart plus, it is truly wonderful for me to see a reliable more economic generic available for animal guardians that is certainly comparable to the more expensive brand name monthly heartworm preventatives. With this Virbac product, not only are clients getting the reliable heartworm prevention record of ivermectin, but also the additional preventative benefits and control of other internal parasites of the digestive tract, including roundworms, hookworms, and in this case tapeworms as well. It is exciting to see the inclusion of praziquantel in this combination product to broaden the spectrum of coverage of Iverhart plus against tapeworms. Tapeworms are among the most common frustrating parasites seen in dogs and cats, especially when there is any risk of flea exposure. Iverhart Max stands alone in having this added benefit of tapeworm control. Even for only this additional benefit, as well as the ones I mention under Iverhart plus , I highly recommend this reliable generic product and alternative to the other more expensive monthly heartworm pills that dont offer this protection against tapeworms. The only negative issue I have seen is the occasional pet who develops digestive upset from one of the ingredients, in which case I would change to a different monthly alternative. The only other possible limitation with this product is that it does not protect or prevent against whipworms, which in certain areas of the United States can be an intestinal parasite that can sometimes cause acute or chronic inflammation of the colon and diarrhea. But in my experience, whipworms are not as common as I used to see in my earlier days of veterinary practice. Thus my overall rating of this product is a 5. Its effectiveness a 4 and its taste a 4 as well. 12/01/2008
    Worm treatment 4 all dogs THIS PRODUCT IS GRrrrrr8, I love to use this heart guard treatment on my 70 Lb mixed breed 5 yr old dog!! I highly recommend this for everyone whom has a dog or puppy no matter what there size is to use this product. they will not be let down... IT works very very good!! Mary Heather Holcher !! 07/14/2008
    I love this product I have two dogs so buying a years worth of heart worm medicine for both of them can be a little pricey on... this product makes it so much more affordable and is really effective. Sometimes my dogs take it by itself, sometimes I have to put it in a pill pocket, but if that's the only issue I'm having, then I'll take it. This is an EXCELLENT product and let's me affordably take care of my fur babies :) 10/08/2014
    The price is right and meds are effective. Hi, we use Iverhart on all three of our dogs, and would use it on our cat if they made such. It is so much cheaper than the Heartgard....and I love 1800 Pet Med, because they will price match any other online stores prices...Their customer service is awesome...I always call and place my order and the assistance I get is always 100% friendly and professional. My dogs love the Iverhart and take it with no problem. I highly recommend. You cant get a better deal on Heart Worm prevention! 09/23/2014

    I gave my Cairn Terrier Iverhart Max today in a Pill Pocket (he refuses to chew these hard monstrosities). I have observed lethargy in him on a previous month but I had been giving him K9 Advantix on the same day, so I tried spacing those out by a week to make sure he wasn't reacting to the Advantix. He was really restless and a little gassy this evening, about four hours after I gave him the pill. When I took him out, he had two BMs and came in with a reddish orange stain on his fur. I wiped his rear and it appears to be blood but he is not bleeding from his anal glands as far as I can tell. He does not appear to be in pain or lethargic. He's alert and interested in everything I do and otherwise acting normal. I will observe his BM in the morning to see if he needs to go to the vet.

    Answer: 
    It's me again. Nikki's stiool did not have an orange tint today, and when I wiped him, the wipe did not have any orange or red on it, so he appears to be alright. He's not gassy or restless, either. I'm glad he's alright, but I'm going to watch for similar reactions next month, if I don't talk to his vet first.

    Answer: 
    Your dog is right on the borderline between doses.
    Your veterinarian can either prescribe the iverhart max 50.1 to 100 plus the iverhart max 6-12 pounds
    or the iverhart max 50.1 to 100 pounds plus the iverhart max 12-25 pound dose. It depends on
    your veterinarian and also your pets weight history. If the pet is usually over 112 pounds, the vet
    might go with the higher dose just to be on the safe side.

    Grandmother always taught me to follow the doctors orders......never to take more medicine than was perscribed. I believe this is good advice for dogs too. Too much of something is not always a good thing. Buy both and follow the directions.

    Is it okay to switch from Iverhart Plus to Iverhart Max at any time? I know you have to have dogs tested for heartworms before starting them on a wormer and since Iverhart Max also guards against tapeworms, I was wondering if they have to be tested for tapeworms or anything before making the switch or if you can just switch at any time.

    Answers

    Answer: 
    You NEVER want to give heartworm medication to any dog that hasn't been tested for heartworm. Heartworm tests MUST be done once a year. Administering a heartworm medication to a dog that has heartworm could kill it, therefore knowing beforehand is a must. Even if your dog has never missed a dose for an entire year, they must have a test every year or veterinarians are not going to "ok" the prescription fulfillment. Also keep in mind, this is not a "preventative," but rather a dewormer, meaning it doesn't protect for the upcoming month, but rather gets rid of whatever the dog may have picked up the previous month. This is one of those areas where you don't want to cut corners, believe me. Heartworm is a brutally harsh disease and it's just not worth risking your dog's life. See your vet at least annually.
