Frequently Asked Questions

Q1: What parasites does Iverhart Max Chew protect against in dogs?

Ans: Iverhart Max Chew helps protect dogs from heartworm disease by killing the early tissue stage of heartworm larvae for up to 30 days after infection. When used as directed, it also treats and controls roundworms, hookworms, and tapeworms in dogs that are eight weeks of age and older.

Q2: How often should I give Iverhart Max Chew to my dog?

Ans: Iverhart Max Chew should be administered orally once every 30 days during the period when mosquitoes are active. The first dose must be given within 30 days after initial exposure, and the final dose within 30 days after the last exposure.

Q3: Does my dog need a heartworm test before starting Iverhart Max?

Ans: Before giving your dog this medication, a heartworm test is essential to rule out an existing infection. Another test should be done about six months after starting prevention to make sure everything is working properly. Since this product does not kill adult heartworms, dogs that are already infected will need proper treatment to clear the adult worms before beginning prevention.

Q4: Is Iverhart Max safe for small or toy breed dogs?

Ans: Iverhart Max Chew is approved for dogs eight weeks of age or older and is available in weight-specific strengths, including for dogs weighing 6 to 12 pounds. Caution is advised in dogs under 10 pounds or those that are sick or debilitated.

Q5: Is Iverhart Max Chew available without a prescription?

Ans: No. Federal law restricts Iverhart Max Chew to use by or on the order of a licensed veterinarian. Pet owners must obtain a valid prescription from their veterinarian before purchasing or administering this heartworm preventive medication.
