Comprehensive Dog Guide to Iverhart Plus

Meet Internal Parasite Preventer: Iverhart Plus!

Iverhart Plus is a prescription-only dog medication that easily and effectively protects your dogs from internal parasitic worms - heartworm, hookworm, roundworm, and other parasites. Iverhart Plus is a monthly, pork-liver flavored chewable oral tablet that also prevents fatal heartworm disease.

How does Iverhart Plus work?

Iverhart Plus is a medication with two active ingredients - Ivermectin and Pyrantel Pamoate.

Ivermectin is an anti-parasitic agent that treats infections caused by roundworms, threadworms, and other parasites. Ivermectin stimulates the excessive release of neurotransmitters thus causing neurological damage which results in the parasite's paralysis and eventual death.

Pyrantel Pamoate is an anthelmintic (i.e., dewormer) that uses a unique paralysis effect against intestinal parasitic worms that attach themselves to the host's intestinal tract with its tiny teeth or suckers. The ingredient acts as a neuromuscular blocker to relax the parasite's grip, is paralyzed, and is effectively eliminated from its unaffected host.

How is Iverhart Plus administered?

Iverhart Plus pork-liver flavored chewable is administered orally once a month, on the same day of every month, all year round. Monitor that the entire chewable is swallowed. Determined by the dog's weight, a recommended box and dosage is administered. See the dosage chart below:

How Often Do You Give Iverhart Plus?

The duration of the administration of any medication depends on the condition of the pets and the speed of the ailments. It is advisable that Iverhart Plus chewable tablets are given once in thirty days. You can note the fact that the initial dose after the exposure to the mosquitos for the first time should be given within a period of one month. The monthly administration of the chewable tablets ensures that the vectors or the mosquitos carrying the larvae of the infestations are treated at the source. As a pet parent, you should look out for signs which can let you know about any worm infestation in your pet. The symptoms that should keep an eye for can include weight loss which is accompanied by an increase or decrease in appetite, loss of hair or dulling of the coat with inflammations and skin irritations, distended or pot-bellied abdomen, chronic coughing, lethargy, diarrhea, vomiting, and soft stools. If you notice any of the above symptoms you should consult your pet's veterinarian to help you with the administration of the right medication and pursue the necessary steps to help your pet get rid of the worm infestations.

Does Iverhart Plus Kill Ticks?

Iverhart plus pork liver flavored chewable tablets are prescription-only medications. The drug has Ivermectin and Pyrantel Pamoate as the chief ingredients in its formulations. It acts as a dewormer for dogs and can effectively kill internal parasitic worms like roundworm, hookworm, heartworm, and other harmful parasitic organisms. You may need the administration of additional medication that can help you kill external parasites like ticks, fleas, or mites. You can also get in touch with your petโ€™s veterinarian when you observe an infestation beyond leaps and bounds and has spread both internally and externally on your pet. These circumstances warrant the need for pest control solutions that can handle such conditions. You being vigilant and checking your pet regularly for any foreign or unwanted organisms can help you identify pest infestations at a very early stage. This in turn can help you to administer the right pest infestation control mechanisms and medication before the widespread impact of the pest occurs.

Should Iverhart Be Given With Food?

The administration of any drug can be done by opting to follow either the instructions mentioned on the packaging of the product or those given by your petโ€™s veterinarian. It is often seen that most pets are fussy while ingesting any medication. A great idea can be to administer Iverhart Max Chewable Tablets with the food or the treat of your petโ€™s choice. You can give Iverhart plus pork flavored chewable tablets in the form as it comes, and your pet may take it directly because of its great flavor and taste. However, if your pet is unwilling to take the medication, you can also try and feed it with a small quantity of food. A crucial aspect to remember here is whatever process you follow you must ensure that the entire dosage is consumed by your pet. You should also be cautious to check whether the entire recommended dose is consumed or rejected by your pet after some time post administration of Iverhart Max Chewable Tablets.

Can Heartworm Pills Cause Diarrhea?

Iverhart Max Chewable Tablet exhibits extraordinary results for the control and treatment of internal worms among most dogs. However, like every commercially available medication in the market, Iverhart Max for oral use in dogs also has a few side effects that can be seen in some pets. Some dogs can experience incoordination, diarrhea, or vomiting. These are found to be common and you should not worry about such symptoms. Another set of symptoms can arise due to allergic reactions triggered by heartworm medications. Under such a scenario, your pet can experience seizures, itching, shock, swelling of the face, or hives.

Can you give ivermectin and pyrantel together?

Both ivermectin and pyrantel are medications used to treat parasitic infections in humans and animals. However, the specific use and dosages of these medications can vary depending on the type of infection and the individual's circumstances. Iverhart Plus is a combination medication that contains both ivermectin and pyrantel. It is commonly used in veterinary medicine for the prevention of heartworm disease and for the treatment and control of various intestinal parasites in dogs. Iverhart Plus is specifically formulated to provide a combination of these two active ingredients in appropriate dosages for dogs. It is typically administered orally in tablet form, following the instructions provided by a veterinarian.

Is ivermectin safe for pets?

Ivermectin can be safe for pets when used appropriately and according to the recommended dosage. However, it's important to note that ivermectin sensitivity can vary among different animal species and even among individual animals within a species. Ivermectin is commonly used in veterinary medicine for the treatment and prevention of various parasitic infections in animals such as dogs, cats, horses, cattle, and others. It is generally considered safe when administered at the appropriate dose for the specific species being treated. However, some dog breeds, particularly herding breeds (e.g., Collies, Australian Shepherds, Border Collies) and certain mixed-breed dogs may have a genetic mutation that makes them more sensitive to the effects of ivermectin. In these breeds, even low doses of ivermectin can potentially cause adverse reactions, including neurological symptoms.

Can I deworm my dog with ivermectin?

Ivermectin is generally considered a safe and effective dewormer for dogs. It is commonly used in veterinary medicine at low doses as a heartworm preventative and at higher doses to treat conditions such as mange. However, it's important to be aware of a genetic mutation known as MDR1 (multi-drug resistance 1) that some dog breeds carry. Certain dog breeds, particularly herding breeds, may have the MDR1 mutation, which can make them more susceptible to toxicity from higher doses of ivermectin and other medications. Dogs with this mutation may experience adverse effects from common drugs, including ivermectin, as well as certain chemotherapy agents and other medications.

Does ivermectin get rid of all worms?

Ivermectin is effective against several types of internal parasites, but it may not eliminate all types of worms. The specific efficacy of ivermectin against different worm species can vary. Ivermectin is commonly used to treat certain types of roundworms, such as Toxocara canis and Toxascaris leonina, as well as some hookworms (Ancylostoma spp.) and whipworms (Trichuris spp.). It can also be effective against external parasites like mange mites. However, ivermectin may not be effective against all types of worms. For example, it may not target tapeworms (Cestodes) or certain species of flukes (Trematodes). Different worm species may require different medications or treatment protocols.

Is pyrantel pamoate safe for dogs?

Pyrantel pamoate is generally considered safe for use in dogs when administered at the appropriate dosage. It is a commonly used medication for the treatment and prevention of various intestinal parasites in dogs, including roundworms (Toxocara canis, Toxascaris leonina), hookworms (Ancylostoma spp.), and some species of whipworms (Trichuris spp.). Pyrantel pamoate works by paralyzing and eliminating these intestinal parasites from the dog's system. It is available in various formulations, including chewable tablets, liquid suspensions, and as an ingredient in combination deworming products. However, as with any medication, there is a possibility of side effects. The most common side effects of pyrantel pamoate in dogs are mild and may include gastrointestinal upset, such as vomiting or diarrhea. These side effects are typically temporary and resolve on their own.

Can I give Pyrantel to my cat?

Never give your cat pyrantel or any other medication intended for dogs, as the dosages and formulations can differ between the two species. Administering incorrect dosages or using inappropriate medications can be harmful to your cat's health. Pyrantel can be used to treat certain parasites in cats, but the formulation and dosage for cats may differ from those for dogs. Pyrantel pamoate is commonly used in cats to treat roundworms (Toxocara cati, Toxascaris leonina) and hookworms (Ancylostoma tubaeforme). Additionally, different products and formulations of pyrantel are available for cats, such as chewable tablets or liquid suspensions specifically formulated for feline use.

Ivermectin and Pyrantel Pamoate

Side effects can include vomiting or diarrhea within 24 hours of dosing, as well as depression/lethargy, loss of appetitie, staggering, convulsions, and hypersalivation. Herding breed dogs have been reported to be more prone to experiencing the side effects of Iverhart Plus.

Give your dog Iverhart Plus once a month on the same day of each month, year-round.

Use on or before the expiration date.

Administer Iverhart Plus once every month. The tablets are intended to be chewed, not swallowed. Break the tablets up, if dog does not want to chew.

Iverhart Plus can be given to your dog by hand, mixed with a small amount of food, or placed in the back of your dogโ€™s mouth for forced swallowing.

Watch your dog closely after giving them Iverhart Plus to be sure the entire dose has been swallowed. If your dog has not completely swallowed the full dose, give them one more full recommended dose as soon as possible

Iverhart Plus should be stored at room temperature.
