Doxycycline (Vibramycin®)


Doxycycline is an antibiotic related to tetracycline.   It is effective against a variety of organisms, and is often used to treat bacterial infections. It is the antibiotic of choice for many diseases (such as Lyme disease) that are spread by ticks and some diseases caused by organisms known as Mycoplasma.  It is commonly employed in the treatment of respiratory infections and fever of unknown origin in cats.

Albon® (Sulfadimethoxine)


In veterinary medicine, sulfadimethoxine is used primarily to treat coccidia (Isospora) in puppies and kittens.  Courses of sulfadimethoxine generally last from 3 to 21 days.

Sulfadimethoxine also may be used as an antibiotic, but this is not common in veterinary medicine.

Sulfadimethoxine is currently considered an inferior treatment option for coccidia.  A different drug, ponazuril, is preferred.

Levothyroxine (Soloxine® and Thyro-Tabs®)


Levothyroxine is used to treat hypothyroidism in dogs. It works by supplementing the dog's production of thyroid hormone. The effect is temporary. Most dogs with hypothyroidism require lifelong treatment with levothyroxine.


Levothyroxine most commonly is administered as an oral pill once or twice daily.

Side Effects

Side effects of levothryoxine are rare but can include gastrointestinal upset.



Insulin is a drug that is used in the treatment of diabetes in dogs and cats. It requires special handling and storage, it must be given by injection, and it carries the risk of overdose. Despite these disadvantages, insulin is the most commonly used drug in the treatment of diabetes. Without insulin, most diabetic cats and dogs will suffer severe or fatal complications of the disease.
