What is Benadryl and its uses for pets?

Benadryl is an antihistamine primarily used to treat allergic reactions in pets. Exposure to allergens like dust, pollen, or grass can trigger the release of histamines and other compounds in pets, leading to symptoms such as:

  • Sneezing
  • Coughing and wheezing
  • Itchy skin, causing excessive scratching
  • Vomiting and diarrhea
  • Gas and bloating

Antihistamines like Benadryl work by reducing the body's reaction to these histamines, alleviating the aforementioned symptoms. Veterinarians might also prescribe Benadryl for issues like anxiety or to prevent motion sickness and nausea.

If your pet experiences severe allergic reactions, known as anaphylaxis, with symptoms like difficulty breathing, facial swelling, seizures, or collapse, immediate veterinary attention is essential. 🏥
