Heartworm disease is a serious and potentially fatal condition affecting dogs and cats, caused by parasitic worms that live in the heart, lungs, and blood vessels. The American Heartworm Society (AHS) is the leading authority on heartworm prevention and treatment, providing guidelines that veterinarians follow worldwide. This comprehensive guide explains the AHS treatment plan, addressing common questions and concerns.
What is the American Heartworm Society's Recommended Treatment?
The AHS treatment protocol focuses on safely and effectively eliminating adult heartworms from the infected pet's system. It's crucial to understand that this is a multi-step process, requiring careful veterinary supervision and monitoring. The treatment typically involves administering a series of medications, most commonly melarsomine dihydrochloride (brand name Immiticide), which kills adult heartworms. This is not a single injection but a course of treatment, usually administered over several weeks, depending on the severity of the infection. The exact dosage and frequency are determined by the veterinarian based on the individual pet's condition, weight, and overall health.
What Medications are Used in the AHS Heartworm Treatment Plan?
The cornerstone medication in the AHS plan is melarsomine. However, supportive medications are often also part of the treatment. These might include:
- Doxycycline: An antibiotic used to kill Wolbachia bacteria, which live symbiotically within heartworms. Removing these bacteria reduces inflammation and helps prevent complications.
- Corticosteroids: These anti-inflammatory drugs can help manage the inflammatory response that sometimes occurs when adult heartworms die. This is especially important in heavily infected animals to reduce the risk of serious complications.
- Pain relievers: These might be necessary to manage any discomfort associated with the treatment process.
The veterinarian carefully selects the necessary medications and dosages based on your pet's specific needs.
How Long Does the AHS Heartworm Treatment Take?
The duration of treatment varies depending on the severity of the infection and the individual pet's health. While the melarsomine injections are spread over several weeks, the overall recovery process can take several months, requiring regular veterinary check-ups. Strict rest is often recommended during treatment to minimize the risk of complications.
What are the Potential Side Effects of the AHS Heartworm Treatment?
While generally safe and effective, the AHS heartworm treatment can have potential side effects. These can range from mild, such as vomiting or lethargy, to more serious complications, such as coughing, difficulty breathing, or a sudden worsening of the condition. That's why close veterinary monitoring is so essential throughout the entire treatment process. Immediate veterinary attention should be sought if any adverse reactions are observed.
What Happens After Heartworm Treatment is Completed?
After treatment, the pet needs ongoing monitoring to ensure the heartworms have been successfully eliminated and that the pet's heart and lungs are recovering well. Regular blood tests will be necessary to confirm the absence of microfilariae (baby heartworms) and to monitor organ function. Furthermore, the pet will need to be on a preventative heartworm medication to prevent re-infection.
What is the Cost of the AHS Heartworm Treatment Plan?
The cost of the AHS heartworm treatment plan can vary significantly based on factors such as your pet's weight, the severity of the infection, and the location of your veterinary clinic. The cost includes the medications, diagnostic tests (such as blood tests and X-rays), and veterinary visits for monitoring. It's always a good idea to discuss the cost with your veterinarian upfront to understand the financial commitment involved.
Can Heartworm Disease Be Prevented?
The best approach to heartworm disease is prevention. Year-round heartworm preventative medication is highly recommended by the AHS, as it is significantly more cost-effective and safer than treating an existing infection. This medication kills microfilariae before they develop into adult worms, preventing the development of the disease.

Always consult your veterinarian for diagnosis and treatment of heartworm disease in your pet. They can assess your pet's individual needs and develop a customized treatment plan based on the AHS guidelines and your pet’s specific health status.
