Dogs (Used in cats in certain circumstances)
Soloxine (levothyroxine) is a replacement for the hormone that the thyroid gland normally produces to regulate the body's energy and metabolism.
Soloxine should not be used if your pet has ever had thyrotoxicosis, or an uncontrolled adrenal gland problem. Tell your veterinarian if your pet has heart disease, anemia, diabetes, or problems with the pituitary or adrenal glands. If you give your pet insulin or diabetes medication by mouth, dose adjustments may need to be made.
