Care for the Ones You Love

At Comal Pet Hospital, it is our policy to take every possible step to ensure that our patients receive the very best and safest pharmaceutical products available. This is especially important with life-threatening illnesses such as heartworm disease. However, we understand and empathize with the desire to find products that are less expensive. We know that several catalog houses and internet pharmacies presently sell these products at a price less than we are able to offer. We do, however, want your decision to be well informed.


Here are 5 truths about these pharmacies that you should know:

  1. The manufacturer cannot guarantee that these medications are safe and effective. Because these medications have been handled through third party veterinarians, usually illegally - the medication companies have no way of knowing what exactly is in those packages and whether they have been tampered with, handled or shipped at appropriate temperatures. The guarantees that these manufacturers offer regarding their products are NULL and VOID if their products are purchased through non-approved channels. This includes the heartworm guarantee for all of the heartworm preventatives. This guarantee involves the drug manufacturer paying for heartworm treatment if a dog becomes heartworm positive while using the product.
  2. All major veterinary drug companies maintain a strict policy of sales exclusively through licensed veterinarians. All other pharmacy sales are through non-approved channels. This means that online pharmacies DO NOT get their products from the drug companies.
  3. Pharmaceuticals manufactured for and labeled for use in other countries (namely Australia and Mexico) have been illegally diverted and sold through these discount houses in the United States. There is also no way to guarantee that the product has been stored appropriately.
  4. Discount houses have been cited by the FDA and State Boards of Pharmacy for violating these procedures.
  5. Our products come with a person to explain the most appropriate medication for your pet, how to use them, and honor the guarantee if they fail to meet your expectations.
