Virbac Announces Voluntary Recall Notice for Selected Production Lots of
IVERHART PLUS Flavored Chewable Tablets
On Thursday, August 13, 2009, Virbac AH, Inc., the manufacturer of IVERHART PLUS Flavored Chewable Tablets, a heartworm preventative medicine, announced a voluntary recall of three product lots. Stability testing revealed subpotent (below specification) ivermectin results in two lots of IVERHART PLUS, large 51-100 lbs. (lots#090093 and #090095) and one lot of IVERHART PLUS, small up to 25 lbs. (lot#090073) nearing the lower potency limit. No other lots have been affected by this recall.
The Lot number is listed on the bottom lid/flap of the box in a white text field and on the blister foil of the individual doses. Virbac will provide full replacement through the distributor network, when the product is returned to the place of purchase.
Virbac cautions that dogs weighing over 75 pounds, which may have been dosed with the indentified lots, may not be currently protected against heartworm disease. Virbac recommends that these dogs receive a heartworm test 5-6 months after the date of the last dose given, in order to verify continued protection against heartworm disease. If any dog receiving IVERHART PLUS Flavored Chewable Tablets was infected with heartworms, treatment can be administered and will be covered under the IVERHART PLUS product guarantee. Virbac Technical Services (800-338-3659 extension 3052 or fax 817-831-9906) is committed to working with clients and veterinary clinics to accomplish any necessary antigen testing of dogs at risk that received the indentified lots.
Virbac is confident that dogs weighing less than 75 pounds and more than 25 pounds are currently protected against heartworm, but the identified product may not work at acceptable levels through the expiration date. Therefore it is important that pet owners and veterinary clinics replace the recalled lots as soon as possible. Since only the ivermectin is affected, there is no additional risk related to the internal parasites covered by the product. |
