Diazepam, commonly known by its brand name Valium, is a prescription medication primarily used in veterinary medicine to treat dogs experiencing anxiety, seizures, or muscle spasms. It belongs to the benzodiazepine class of drugs and works by calming the central nervous system. In dogs, diazepam is often administered in cases of status epilepticus (prolonged seizures), as a sedative before procedures, or to relieve anxiety caused by travel, loud noises (like fireworks), or separation. Veterinarians may also prescribe diazepam to stimulate appetite in dogs that refuse to eat due to illness or stress. While not a vaccine, diazepam is an essential emergency medication and should only be used under strict veterinary guidance due to potential side effects like drowsiness, lack of coordination, or liver complications (especially in long-term use). The dosage is carefully calculated based on the dog’s weight and medical condition.
