TERRE HAUTE —
Heartworms are life-threatening for dogs and cats. Currently, the only FDA drug approved to treat heartworms, Immiticide, is off the market indefinitely.
The manufacturer, Merial, may not be able to produce the drug for months, and heartworm-infected dogs need the drug to survive. There are no other approved products available for killing adult heartworms.
More than ever it is important to keep your dog on preventative heartworm treatment.
The best course of action is prevention. If your dog is not on preventative treatment, talk to your veterinarian as soon as possible. Your dog should be tested for heartworms before starting a preventive treatment drug. If he tests negative, preventative treatment can begin immediately.
He should be retested in six months. If adult heartworms are present in the heart, he will test positive. As the heartworm test does not detect adult heartworms that have not yet traveled to the heart through the bloodstream, a dog can test negative initially, then test positive six months later.
If your dog tests positive for heartworms, veterinarians have established a protocol to help your pet survive until the shortage is resolved. These treatments may not successfully eliminate the adult heartworms but could help your dog survive the infection until more Immiticide is made available.
The American Heartworm Society strongly recommends limiting the physical activity of infected dogs. Physical activity can increase the severity of the heartworm infection.
Your veterinarian will prescribe a preventative medicine in order to kill the larvae (immature heartworms).
This will prevent further infection of adult heartworms in the heart but not kill the adult heartworms already in the heart. While the unavailability persists, the goal is to reduce the potential pathology from the infection, maintain the health of the dog until it can be treated, and to prevent additional heartworm infection in the dog.
In order that these goals may be achieved, it’s important to limit the activity level of the dog, place the dog on heartworm prevention, and administer doxycycline to reduce pathology and infective potential of the heartworms.
This is not the first incident of an Immiticide shortage and little information is known regarding the shortage, although technical difficulties are said to be responsible. Merial is presently seeking alternative sources for this medicine.
Grace
• Grace is a small bundle of 9-month-old puppy energy but she can also settle down and be a cuddle bug, as well. She loves to play with her toys, especially her rope and tennis ball. She plays fetch but is still learning to return the ball. Grace is 99 percent housebroken. She is kenneled at night and does not mess in her kennel all night long. Grace has learned to sit on command and patiently waits for treats. She has adjusted well in her foster home and is good around other dogs, horses and children. The only thing missing in Grace’s life right now is a forever home. If you feel you would be the right family for Grace, contact the Terre Haute Humane Society at (812) 232-0293. She is already spayed and ready to go home with an approved application.
