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 of levothryoxine are rare but can include gastrointestinal upset.
Dogs taking levothyroxine require regular blood tests as well as monitoring of weight and clinical symptoms. Dosage adjustments and discontinuation of medication should occur only under the supervision of a veterinarian.
