Pit Viper Antivenin
別名: CroFab, Antivenin
> **Medical Emergency**: Snakebites are life-threatening emergencies. Immediate veterinary intervention is required. * **High Cost**: Antivenin therapy is very expensive. Depending on the severity of the bite and the size of your pet, multiple vials may be necessary. * **Intensive Care**: Treatment involves more than just the antivenin. Your pet will likely require hospitalization, aggressive IV fluid therapy, pain management, and continuous monitoring. * **Allergic Reactions**: Because the antivenin is derived from horse or sheep proteins, there is a risk of severe allergic reactions (anaphylaxis) during administration, or delayed reactions (serum sickness) days to weeks later. Your veterinarian will monitor closely for these complications.
劑量必須由獸醫按你寵物的個別情況決定。切勿在沒有獸醫指導下給予人類藥物或其他寵物的處方藥。
用途
- Pit viper envenomation
- Systemic effects of envenomation
- Pit viper envenomation
- Pit viper envenomation
給藥方式
可能的副作用
- Anaphylaxis (Type I hypersensitivity)
- Anaphylactoid reactions
- Serum sickness (Type III hypersensitivity, delayed)
- Nausea
- Pruritus
- Hyperemia of the inner pinna
注意事項與禁忌
- Known severe hypersensitivity to equine or ovine proteins (relative contraindication in life-threatening envenomation)
- High risk of anaphylaxis due to equine-origin proteins. A test dose (1:10 dilution intracutaneously) is sometimes suggested but evaluation is difficult. Slow IV administration is usually sufficient to identify reactive animals. Pre-treatment with diphenhydramine is highly recommended to sedate the patient and reduce allergic reactions. If an anaphylactoid reaction occurs (nausea, pruritus, pinna hyperemia), stop the infusion, administer additional diphenhydramine, and restart 5 minutes later at a slower rate.
藥物相互作用
- Analgesics/Sedatives: May mask the clinical signs associated with the venom; use with caution initially.
- Antihistamines: Theoretical risk of potentiating venom, though diphenhydramine is routinely and safely used by clinicians for pre-treatment.
- Beta-blockers: May mask the early signs associated with anaphylaxis.
- Corticosteroids: Generally out of favor for treating snakebite envenomation, but may be useful to treat secondary anaphylaxis. Contraindicated in horses per some references.
- Heparin: Reportedly not effective in treating the thrombin-like enzymes found in rattlesnake venom.
