Levothyroxine (AKA L-Thyroxine or T4) is a hormone replacement drug which is used to combat hypothyroidism (underactive thyroid). By supplementing your dog with the hormone his own body is failing to produce enough of you can effectively regulate their energy and metabolism. It is used as the active ingredient in a variety of branded medicines including Soloxine, Synthroid and Thyro-Tabs. Levothyroxine and medicines which are composed of the substance are FDA approved for use in dogs though long term use may lead to problems such as osteoporosis.
Soloxine dosage for dogs
Soloxine is available as tablets ranging from 0.1 to 1 mg each. The recommended dosage for dogs is 0.01 mg/lb body weight to be administered twice daily. As an example, a 60 lb dog would need 60 x 0.01 mg = 0.6 mg of Soloxine per dose. The dosage may be altered according to results gathered by regular blood tests. The dosage may also be altered if your dog is taking other medication which is known to interact with levothyroxine.
Is Soloxine safe for dogs?
Soloxine is a safe substance for use in dogs with hypothyroidism, but special care has to be taken when using the drug. Usually dogs who need Soloxine will remain on the medication for the rest of their lives, which means they are at a high risk of eventually developing osteoporosis. Some evidence suggests that supplementing dogs with glucosamine may help treat/prevent osteoporosis but it has not yet been officially confirmed and some dogs may experience a bad reaction with this combination. There are also many medicines and supplements which interact with Soloxine so extra care should be taken of what you give your dog whilst he/she is taking it.
- Always consult with your vet before giving Soloxine to your dog
- Become familiar with medicines and substances which interact with Soloxine especially if your dog will be taking the medication long-term
- Notify the vet of any vitamins, medicines or supplements your dog is taking including herbal remedies
- Arrange for regular blood tests to check your dog’s T4 level
