Things You'll Need:
- Prescription from your veterinarian
-
Step 1
Speak to a veterinarian about obtaining a written prescription for the heartworm preventative. These products are currently available by prescription only, meaning you cannot legally purchase them without a prescription from a licensed veterinarian. Most veterinarians are willing to provide these prescriptions free of charge as a professional courtesy, however, some may charge a fee.
-
Step 2
Shop around to find the best price. There are several websites that offer the products and prices can vary widely. Don't forget to check shipping charges and factor these into the final cost.
-
Step 3
Follow the ordering instructions on the website. Be sure to pay special attention to the instructions listed on the site regarding the submission of your prescription. In some cases, you might be asked to mail your written prescription. In other situations, you might be asked to provide your veterinarian's contact information so the company can verify the prescription. If you are uncomfortable with submitting your information online, most sites also offer an "order by mail" option.
-
Step 4
Once your heartworm preventative has arrived, simply administer the treatment as usual.
