Procaine with Epinephrine
別名: Willcain
Your pet has received a local anesthetic to numb a specific area for a procedure. > **Important:** The area may remain numb for a few hours. Prevent your pet from chewing, scratching, or rubbing the numb area, as they could cause severe self-injury without feeling it. Monitor the injection site for any signs of excessive swelling, redness, or skin discoloration, and contact your veterinarian if you notice any unusual behavior.
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。
給藥方式
可能的副作用
- Local tissue irritation
- Ischemia or tissue necrosis (due to epinephrine)
- CNS excitation followed by depression (at toxic doses)
- Cardiovascular depression, hypotension, or arrhythmias (at toxic doses)
- Allergic reactions (ester anesthetics are metabolized to PABA, a known allergen)
注意事項與禁忌
- Intravenous administration
- Use in areas supplied by end-arteries (e.g., tail, ears, digits) due to risk of ischemic necrosis
- Known hypersensitivity to ester-type local anesthetics or PABA
- Epidural use (depending on specific formulation preservatives)
- > **WARNING:** Do not use epinephrine-containing solutions in extremities or areas with collateral-poor circulation (e.g., tail, ears, digits) due to the risk of severe ischemia and tissue sloughing. Always aspirate the syringe before injecting to ensure the needle is not in a blood vessel, as accidental intravenous injection can cause severe cardiovascular and CNS toxicity.
藥物相互作用
- Sulfonamide antibiotics: Procaine is metabolized to PABA, which competitively antagonizes the antibacterial effect of sulfonamides.
- Alpha-adrenergic blockers: May antagonize the vasoconstrictive effects of epinephrine.
- Halothane: Sensitizes the myocardium to catecholamines; increased risk of arrhythmias with epinephrine.
