How many isoniazid tablets would it take to poison a dog? - briefly

Isoniazid is a medication used to treat tuberculosis in humans, but it can be highly toxic to dogs. The toxicity of isoniazid in dogs depends on various factors, including the size and health of the dog, as well as the specific formulation and dosage of the tablets.

Toxic doses of isoniazid for dogs can range from 15 to 30 mg per kilogram of body weight. Symptoms of isoniazid poisoning in dogs may include vomiting, seizures, and even coma. Immediate veterinary attention is crucial if ingestion is suspected.

The lethal dose of isoniazid for dogs is approximately 30-50 mg per kilogram of body weight. However, it is important to note that even smaller amounts can cause severe symptoms and should be treated as an emergency.

If a dog ingests isoniazid, it is essential to seek veterinary care immediately. Treatment may involve inducing vomiting, administering activated charcoal, and providing supportive care to manage symptoms. In severe cases, hospitalization and intensive care may be necessary.

Owners should keep all medications, including isoniazid, out of reach of pets to prevent accidental ingestion. If you suspect your dog has ingested isoniazid, contact your veterinarian or a pet poison helpline immediately for guidance.

The exact number of isoniazid tablets that could poison a dog varies based on the strength of the tablets and the weight of the dog. Generally, ingestion of even a single tablet can be dangerous and potentially lethal, depending on these factors.

How many isoniazid tablets would it take to poison a dog? - in detail

Isoniazid is a medication primarily used to treat tuberculosis in humans. However, it is highly toxic to dogs and can be fatal if ingested. The toxicity of isoniazid in dogs is primarily due to its ability to cause severe neurological symptoms and liver damage. Understanding the potential lethality of isoniazid in dogs requires consideration of several factors, including the dog's size, the dosage ingested, and the timely administration of veterinary care.

Dogs are particularly sensitive to isoniazid because they lack the enzyme necessary to metabolize the drug effectively. This metabolic deficiency makes even small amounts of isoniazid dangerous. The toxic dose of isoniazid in dogs is relatively low compared to other species. As little as 10-20 mg per kilogram of body weight can be toxic, and doses exceeding 20 mg per kilogram can be lethal. For example, a 10 kg dog could potentially be poisoned by ingesting just 100-200 mg of isoniazid, which is roughly equivalent to 2-4 standard 300 mg tablets.

Symptoms of isoniazid poisoning in dogs typically appear within a few hours of ingestion and can include:

  • Vomiting
  • Seizures
  • Lethargy
  • Ataxia (loss of coordination)
  • Coma
  • Respiratory failure

If a dog ingests isoniazid, immediate veterinary intervention is crucial. Treatment typically involves inducing vomiting to remove any remaining drug from the stomach, administering activated charcoal to prevent further absorption, and providing supportive care such as intravenous fluids and anticonvulsant medications. In severe cases, pyridoxine (vitamin B6) may be administered as an antidote, as it can help counteract the neurological effects of isoniazid.

Preventing isoniazid poisoning in dogs involves keeping all medications, including prescription drugs, out of reach. Pet owners should be aware of the potential dangers of common household medications and ensure that their pets do not have access to them. If accidental ingestion is suspected, prompt veterinary attention is essential to minimize the risk of severe toxicity or fatal outcomes. Always consult with a veterinarian or a poison control center for specific advice tailored to the situation.
