How is it given?
Most dogs like the taste of Iverheart Max and will accept the chewable tablet as a treat. The chewable should be administered in a manner that encourages the dog to chew, rather than to swallow without chewing. Iverhart Max Chewables may be broken into pieces and fed to dogs that normally swallow treats whole. Care should be taken that the dog consumes the complete dose, and treated animals should be observed for a few minutes after administration to ensure that part of the dose is not lost or rejected. If not entirely consumed, give another full recommended dose as soon as possible.

Common Drug Name
What should I discuss with my veterinarian while considering Iverhart Max?
Collies or other herding breeds may have a reaction to ivermectin if given over the recommended heartworm prevention dose. If your dog is one of these breeds, and your veterinarian has prescribed Iverhart Max, observe your pet for at least 8 hours after giving the medication for weakness, staggering, dilated pupils, trembling, drooling, or pressing the head against a wall. Contact your veterinarian immediately if you see these signs.
Some intestinal parasites, such as hookworms and roundworms can be spread to people. Talk to your veterinarian about other measures you can take to prevent your pet from being infected with intestinal worms, and protecting yourself.
Notify your veterinarian of any other medications or supplements your dog is taking, and also if your dog has had any reactions to previous medications.

|Q.||What is heartworm disease and why is it bad for my dog?|
Adult heartworms lay very tiny larvae called microfilariae, which circulate in the blood. They enter a mosquito when it sucks the blood of an infected animal. They mature in the mosquito and then enter the animal's skin when an infected mosquito bites the animal. When the larvae reach about 3 inches, they migrate to the animal's heart where they grow into adults, sometimes reaching a length of 14 inches.
Severely infected dogs can have up to several hundred heartworms in their hearts and vessels. The adult worms can obstruct the chambers of the heart and the various large blood vessels leading to and from the heart and lungs. In severe infections, other organs, such as the liver, can also be damaged.
|Q.||Does my dog need a test before I start giving him Iverhart Max?|
The American Heartworm Society advises that all adult dogs being started on a heartworm preventative for the first time be tested. After that, periodic, but not necessarily annual re-testing should be performed. The frequency of testing should take into account variables such as:
Consult with your veterinarian to determine the appropriate testing schedule for your dog.
|Q.||How often should I give this medication to my dog?|
|A.||Iverhart Max is meant to be given every 30 days. When you start your dog on Iverhart Max,, make sure to give it to him on the same day every month.
|Q.||When should I start giving my dog Iverhart Max during the year?|
|A.||Remember that Iverhart Max kills heartworm larvae your dog was exposed to in the preceding 30 days, so if you give your dog a preventative seasonally, give it to him a month after the first mosquito appears, or when your veterinarian recommends starting.
|Q.||What if I miss a dose?|
|A.|| If the interval between doses exceeds 30 days, ivermectin's efficacy can be reduced. Therefore, if you miss a dose, give Iverhart Max as soon as you remember that you missed it. Talk to your veterinarian to see when they recommend your dog's next heartworm test.
|Q.||I have heard that Collies and other herding breeds have trouble with ivermectin. What can you tell me about this?|
|A.||Some dogs of the Collie breed and related breeds may have a sensitivity to ivermectin, especially at doses much higher than those found in heartworm preventives. The dose of ivermectin in a monthly heartworm preventative is relatively low. Please contact your veterinarian for more information.
|Q.||When should I start giving my puppy Iverhart Max?|
|A.||You can start giving Iverhart Max after your puppy reaches 6 weeks of age.
