*Caution should be used when administering a macrocyclic lactone to dogs with high circulating microfilaria counts. PH12 administered at 3x label dose in heartworm-positive dogs had no adverse clinical effects.

Doses sold are calculated using a standard dog weight of 44 lbs and provide an estimate of the number of dogs treated. The actual number of dogs treated can't be determined from sales or adverse drug event data.

§Rare means more than 1 but less than 10 adverse events per 10,000 doses.4 This is a reporting rate, because the total number of dogs treated is unknown. Reporting rates can underestimate the actual number of adverse events, due to underreporting of adverse events.

IMPORTANT SAFETY INFORMATION: Use PROHEART 6 in dogs 6 months of age or older and PROHEART 12 in dogs 12 months of age or older. Do not administer to dogs that are sick, debilitated, underweight, have a history of weight loss, or to those previously found to be hypersensitive to the drug. Hypersensitivity reactions may occur in some dogs when PROHEART is administered alone or with vaccines. Anaphylactic and anaphylactoid reactions can result in death and should be treated immediately with the same measures used to treat hypersensitivity reactions to vaccines and other injectable products. Reported side effects in clinical trials included vomiting, lethargy, diarrhea, anorexia, and hypersensitivity reactions. People should avoid inhalation, contact with eyes, or accidental self-injection. Certification is required before veterinarians and staff administer these products. See full Prescribing Information for PROHEART 6 and PROHEART 12, attached.
