Injectable Heartworm Preventive


Another product that was first approved for use in 2001 in dogs is an injectable moxidectin product that works for six months as a heartworm preventive. It also kills hookworms with just one injection. This product was voluntarily recalled in 2004 and then re-introduced in 2008 under a risk management program in agreement with the U.S. Food and Drug Administration. Veterinarians that offer this product must be registered with the manufacturer and be trained in its use before being able to purchase the product.


Only a veterinarian is allowed to inject this product, and only after you are given information about its risks and side effects. You must sign a consent form and veterinarians are required to keep records of each product’s lot number in case any side effects are reported. Adverse effects for this product can include facial swelling, itching, vomiting, diarrhea, seizure, or shock.


Other Heartworm Medication Safety Tips


Here are just a few more basic tips to consider when giving your dog heartworm preventives:


  • Check with your veterinarian for the proper dosage and type of heartworm medication to give your dog, before giving it.
  • Read all labels carefully before use.
  • Do not allow products to be within the reach of children or pets (e.g., keep them in a locked cabinet).
  • Watch your dog for side effects and call your veterinarian to report any problems.
  • Do not give your dog more than one type of heartworm preventive medication at a time.
  • Ask your veterinarian if your dog requires heartworm preventive all year long. This is an especially practical approach in the warmer climates, where mosquitoes are always present.
