  • Once-a-month oral preventative
  • Convenient protection against tapeworms, heartworms, hookworms and roundworms

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 tapeworms, 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.

Federal (U.S.A.) law restricts this drug to use by or on the order of a licensed veterinarian

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: Ivermectin has shown the following side affects in few cases: 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.

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 or 12 tablets.
