Albon (Sulfadimethoxine) for Dogs

A sulfonamide antibiotic, Sulfadimethoxine, is prescribed by vets as Albon (brand name) chiefly for treating and managing coccidiosis. However, the active ingredient in Albon Sulfadimethoxine also helps deal with a wide variety of microbial infections in dogs and cats. Veterinarians mainly prescribe Albon as an extra-label medication for effectively treating bacterial enteritis resulting from coccidiosis caused by the parasite Coccidia.

As a veterinary antimicrobial drug, Albon is administered to pet dogs (and cats as well) for managing genitourinary, respiratory, and soft-tissue infections.

 Can You Administer Albon Safely to Your Dog?

As the US Food & Drugs Administration (USFDA) has sanctioned the use of Sulfadimethoxine for pets, you can offer Albon to your dog. However, you must see to it that you provide precisely the dosage recommended by your vet to prevent side effects. Your vet will not prescribe Albon if your dog is susceptible to sulfonamides, thiazides or sulfonylureas.

Albon also may not be suitable for your pet if the animal is pregnant or lactating, has difficulty urinating or suffers from liver or kidney disease. This antibiotic is also not prescribed for pets having a marked history of any blood-related condition.

 What is the Mechanism of Action of Albon in Dogs?

Extensive laboratory tests have made it apparent that Sulfadimethoxine is supremely effective against microorganisms like salmonella, escherichia, staphylococci, streptococci, proteus, shigella, and klebsiella. These bacteria are chiefly responsible for causing enteric, soft-tissue, respiratory, and genitourinary infections in dogs. Sulfadimethoxine, like all sulfonamides, functions as a bactericidal agent, interfering with and obstructing folic acid synthesis by these bacterial parasites.

Additionally, the capability of the cells constituting the dog's genitourinary and respiratory organs to use folic acid increases in the proximity of Sulfadimethoxine. The drug impedes the production of folic acid by the microorganisms, which ultimately obstructs their capability to propagate. Sulfonamides also tend to stay in the dog's gut and urinary tract for a long time which helps in decimating the bacteria.

The Prescribed Albon Dose You Can Give to Your Dog

The usual dosage is usually one tablespoon of Albon for every 10 pounds of your dog's weight (25mg/lb or 55mg/kg) on the first day. Dosage for the next day and after every subsequent day is ½ tablespoon or 12.5mg/lb (27.5mg/kg). You should abide by your vet's instructions as far as the administration of the appropriate dosage is concerned.

At the same time, you should see that you complete the entire course of the medication. Do not stop offering the medicine even if you notice an improvement in symptoms unless instructed otherwise.

Side Effects and Overdosing Symptoms

Some of the potential side effects of Sulfadimethoxine comprise vomiting, reduced appetite, skin rashes, diarrhea, and fever. Make sure your pet drinks sufficient water all through the duration of the therapy. Some side effects are pretty severe but rarely occur, and these include jaundice, liver or kidney disease, vertigo, hives, keratoconjunctivitis sicca (dry eye), polyarthritis, sulfa crystallization in the urinary tract. Other less common side effects include anemia, anaphylaxis, and low WBC (white blood cell) count.

If you observe any of the above side effects in your dog, you can conclude that you've overdosed. If the side effect(s) continue, then you should contact your vet at the earliest or call up the ASPCA's 'Animal Poison Control Center Helpline' (1-888-426-4435) 

Drug Contraindications: When Not to Offer Albon to Dogs

You should exercise caution while offering antacids to your dog if you've already started the pet on Sulfadimethoxine. Let your vet know your dog's medical history and any medications you're offering. Do not give Albon to the dog if the animal is hypersensitive to sulfonamides, sulfonureas or thiazides.

Don't administer the medication if your pet is pregnant, nursing or suffers from acute kidney or liver dysfunction.
