Thyforon 400 Tablet for Dogs - per Tablet
710295
Thyforon 400 is a veterinary medication designed to treat hypothyroidism in dogs. It contains levothyroxine sodium, a synthetic form of thyroxine (T4), which replaces the deficient thyroid hormone. This condition affects a dog’s metabolism, energy levels, and overall well-being. Thyforon 400 helps restore thyroid hormone levels, alleviating symptoms and supporting normal physiological functions.
Hypothyroidism is a common endocrine disorder in dogs, typically caused by autoimmune destruction of the thyroid gland or idiopathic atrophy. The condition results in a slowed metabolism, weight gain, lethargy, and poor coat quality. Thyforon 400 is a prescription medication and must be administered under veterinary supervision.
How Thyforon 400 Works
Thyforon 400 contains levothyroxine sodium, which acts as a replacement for thyroxine (T4), the hormone normally produced by the thyroid gland. Thyroxine is essential for regulating metabolism, body temperature, cardiovascular function, and skin and coat health.
When a dog has hypothyroidism, the thyroid gland fails to produce sufficient hormones, leading to metabolic slowdown and a range of health problems. By supplementing the missing hormone, Thyforon 400 restores normal metabolic activity. The body converts levothyroxine into triiodothyronine (T3), the active form of the hormone, which supports proper organ function and energy regulation.

Symptoms of Hypothyroidism in Dogs
Hypothyroidism often develops gradually, and symptoms may not be immediately noticeable. The condition is most common in middle-aged and older dogs, particularly in certain breeds such as Golden Retrievers, Labrador Retrievers, and Doberman Pinschers. Common signs include:
- Unexplained weight gain despite a normal diet
- Fatigue, weakness, and reduced interest in exercise
- Thinning coat or hair loss, especially on the tail and trunk
- Dry, flaky skin and recurrent skin infections
- Intolerance to cold temperatures
- Slow heart rate (bradycardia)
- Behavioural changes, including depression or lack of alertness
Because these symptoms can also be associated with other medical conditions, a veterinarian will perform diagnostic tests, including blood work, to confirm hypothyroidism before prescribing Thyforon 400.
Dosage and Administration
Thyforon 400 is available in flavoured tablet form to make administration easier. It can be given directly to the dog or mixed with food. The correct dosage is determined based on the dog's weight, thyroid hormone levels, and response to treatment.
Veterinarians typically start with a standard dose and adjust it based on follow-up blood tests. It is important to administer Thyforon 400 at the same time each day to maintain stable hormone levels. If a dose is missed, it should be given as soon as possible, unless it is close to the next scheduled dose.
Monitoring and Long-Term Management
Dogs receiving Thyforon 400 require regular blood tests to monitor thyroid hormone levels and assess the effectiveness of treatment. The first follow-up test is usually conducted four to six weeks after starting medication, followed by periodic evaluations as recommended by the veterinarian.
Signs that the medication is working include increased energy, improved coat quality, and stabilised weight. If the dosage is too high or too low, adjustments may be needed to maintain proper thyroid hormone levels. Owners should monitor their dog's behaviour and physical condition and report any concerns to their veterinarian.
Potential Side Effects
When administered at the correct dosage, Thyforon 400 is generally well tolerated. However, excessive thyroid hormone levels can lead to hyperthyroidism-like symptoms, including:
- Increased heart rate and restlessness
- Excessive thirst and frequent urination
- Diarrhoea or vomiting
- Unexplained weight loss despite normal appetite
If any of these symptoms occur, veterinary advice should be sought immediately, as the dosage may need adjustment. Regular monitoring helps prevent complications and ensures the medication remains effective.
Storage and Handling
Thyforon 400 should be stored in a cool, dry place, away from moisture and direct sunlight. The tablets should be kept in their original packaging and out of reach of children and animals. Any unused or expired medication should be disposed of according to veterinary guidelines.
