IVERHART MAX Soft Chew are recommended for dogs 8 weeks of age and older.

For dogs over 100 lbs use the appropriate combination of these soft chews.

Remove only one soft chew at a time from the foil-backed blister card. Because most dogs find IVERHART MAX Soft Chew 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 MAX Soft Chew 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 MAX Soft Chew 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 soft chew 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 MAX Soft Chew and resumption of the recommended dosing regimen will minimize the opportunity for the development of adult heartworms.

Monthly treatment with IVERHART MAX Soft Chew also provides effective treatment and control of tapeworms (Dipylidium caninum, Taenia pisiformis), roundworms (Toxocara canis, Toxascaris leonina) and hookworms (Ancylostoma caninum, Uncinariastenocephala, Ancylostoma braziliense).

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 MAX Soft Chew 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 MAX Soft Chew. While some microfilariae may be killed by the ivermectin in IVERHART MAX Soft Chew at the recommended dose level, IVERHART MAX Soft Chew 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.
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 MAX Soft Chew are available in four dosage strengths for dogs of different weights. Each strength comes in a color-coded box of 6 bacon flavored, soft chews.
