Iverhart Plus is an anthelmintic (dewormer). The ingredient pyrantel pamoate is used to treat and control roundworms and hookworms in dogs.

DIRECTIONS: Iverhart Plus is a prescription medication available as pork liver flavored chewable tablets. The usual dose of Iverhart Plus in dogs up to 25 pounds is 68mcg/57mg (Blue box), for dogs 26-50 pounds is 136mcg/114mg (Green box) and for dogs 51-100 lbs 272mcg/227mg (Brown box). Dogs over 100 lbs are given a combination of tablets. Give Iverhart Plus exactly as directed by your veterinarian. If you do not understand the directions ask your pharmacist or veterinarian to explain them to you. Use with caution in collies. Heartworm testing should be performed prior to the start of prevention therapy. If your pet is off Iverhart Plus for 6 months or less, start the medication and test after 6 months since microfilaria, that take 6 months to mature, will result in a positive test result. Store Iverhart Plus at room temperature. Do not remove the tablet from its wrapper until ready to give to your pet. Keep this medication away from children and pets. If a dose is forgotten the Give the missed dose as soon as you remember. Do not give a double dose of the medication.

SIDE EFFECTS: Side effects of Iverhart Plus are rare at the recommended heartworm prevention dose. Higher doses in dogs may cause tremors, dilated pupils, loss of body weight, or death.

CAUTION(S): Because humans can contract hookworms from animals, it is important to maintain good personal hygiene. It is also important to eliminate fleas on your pet and in the household and to not feed your pet rodents or uncooked meat or fish. To prevent re-infection, daily cleanup of stools is recommended. Do not give Iverhart Plus if your pet is already being given another heartworm medication.

• Caution: Federal (U.S.A.) law restricts this drug to use by or on the order of a licensed veterinarian.
• INDICATIONS: For use in dogs to prevent canine heartworm disease by eliminating the tissue stage of heartworm larvae (Dirofilaria immitis) for a month (30 days) after infection and for the treatment and control of ascarids (Toxocara canis, Toxascaris leonina) and hookworms (Ancylostoma caninum, Uncinaria stenocephala, Ancylostoma braziliense).
• DOSAGE: IVERHART™ Plus (ivermectin/pyrantel) Flavored Chewables should be administered orally at monthly intervals at the recommended minimum dose level of 6 mcg of ivermectin per kilogram (2.72 mcg/lb) and 5 mg of pyrantel (as pamoate salt) per kg (2.27 mg/lb) of body weight. The recommended dosing schedule for prevention of canine heartworm disease and for the treatment and control of ascarids and hookworms is as follows:

• IVERHART Plus Flavored Chewables are recommended for dogs 6 weeks of age and older.
• For dogs over 100 lbs use the appropriate combination of these flavored chewables.
• ADMINISTRATION: Remove only one flavored chewable at a time from the foil-backed blister card. Because most dogs find IVERHART Plus Flavored Chewables palatable, the product can be offered to the dog by hand. Alternatively, it may be added intact to a small amount of dog food or placed in the back of the dog's mouth for forced swallowing. 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 it is suspected that any of the dose has been lost, redosing is recommended.
• IVERHART Plus Flavored Chewables should be given at monthly intervals during the period of the year when mosquitoes (vectors), potentially carrying infective heartworm larvae, are active. The initial dose must be given within a month (30 days) after the dog's first exposure to mosquitoes. The final dose must be given within a month (30 days) after the dog's last exposure to mosquitoes.
• When replacing another heartworm preventive product in a heartworm disease prevention program, the first dose of IVERHART Plus Flavored Chewables must be given within a month (30 days) of the last dose of the former medication.
• If the interval between doses exceeds a month (30 days), the efficacy of ivermectin can be reduced. Therefore, for optimal performance, the chewable must be given once a month on or about the same day of the month. If treatment is delayed, whether by a few days or many, immediate treatment with IVERHART Plus Flavored Chewables and resumption of the recommended dosing regimen will minimize the opportunity for the development of adult heartworms.
• Monthly treatment with IVERHART Plus Flavored Chewables also provides effective treatment and control of ascarids (T. canis, T. leonina) and hookworms (A. caninum, U. stenocephala, A. braziliense). Clients should be advised of measures to be taken to prevent reinfection with intestinal parasites.
• EFFICACY: IVERHART Plus Flavored Chewables, given orally using the recommended dose and regimen, are effective against the tissue larval stage of D. immitis for a month (30 days) after infection and, as a result, prevent the development of the adult stage. IVERHART Plus Flavored Chewables are also effective against canine ascarids (T. canis, T. leonina) and hookworms (A. caninum, U. stenocephala, A. braziliense).
• ACCEPTABILITY: In a trial in client-owned dogs, IVERHART Plus Flavored Chewables were shown to be a palatable oral dosage form consumed at first offering by the majority of dogs.
• PRECAUTIONS: All dogs should be tested for existing heartworm infection before starting treatment with IVERHART Plus Flavored Chewables which are not effective against adult D. immitis. Infected dogs must be treated to remove adult heartworms and microfilariae before initiating a program with IVERHART Plus Flavored Chewables.
• While some microfilariae may be killed by the ivermectin in IVERHART Plus Flavored Chewables at the recommended dose level, IVERHART Plus Flavored Chewables are not effective for microfilariae clearance. A mild hypersensitivity-type reaction, presumably due to dead or dying microfilariae and particularly involving a transient diarrhea, has been observed in clinical trials with ivermectin alone after treatment of some dogs that have circulating microfilariae.
• Keep this and all drugs out of the reach of children. In case of ingestion by humans, clients should be advised to contact a physician immediately. Physicians may contact a Poison Control Center for advice concerning cases of ingestion by humans.
• Store at controlled room temperature of 59°-86°F (15°-30°C).
• Warnings: Use product on or before expiration date. Discard or return unused tablets.
• Protect product from light.
• ADVERSE REACTIONS: In clinical trials with ivermectin, vomiting or diarrhea within 24 hours of dosing was rarely observed (1.1% of administered doses). The following adverse reactions have been reported following the use of ivermectin: Depression/lethargy, vomiting, anorexia, diarrhea, mydriasis, ataxia, staggering, convulsions and hypersalivation.
• SAFETY: Studies with ivermectin indicate that certain dogs of the Collie breed are more sensitive to the effects of ivermectin administered at elevated dose levels (more than 16 times the target use level of 6 mcg/kg) than dogs of other breeds. At elevated doses, sensitive dogs showed adverse reactions which included mydriasis, depression, ataxia, tremors, drooling, paresis, recumbency, excitability, stupor, coma and death. Ivermectin demonstrated no signs of toxicity at 10 times the recommended dose (60 mcg/kg) in sensitive Collies. Results of these trials and bioequivalency studies, support the safety of ivermectin products in dogs, including Collies, when used as recommended.
• Ivermectin has shown a wide margin of safety at the recommended dose level in dogs, including pregnant or breeding bitches, stud dogs and puppies aged 6 or more weeks. In clinical trials, many commonly used flea collars, dips, shampoos, anthelmintics, antibiotics, vaccines and steroid preparations have been administered with ivermectin/pyrantel in a heartworm disease prevention program.
• In one trial, where some pups had parvovirus, there was a marginal reduction in efficacy against intestinal nematodes, possibly due to a change in intestinal transit time.
• HOW SUPPLIED: IVERHART Plus Flavored Chewables are available in three dosage strengths (see Dosage section) for dogs of different weights. Each strength comes in a box of 6 tablets, packed 10 boxes per display box and in a bulk dispenser carton containing 20 cards of 6 tablets per card.
