Penicillin G
別名: Bicillin C-R, Masti-Clear, Permapen, Pfizerpen, Go-Dry
* **Administration:** Give oral penicillins on an **empty stomach** (1 hour before or 2 hours after a meal) to maximize absorption. If your pet experiences stomach upset (vomiting, loss of appetite), you may give it with a small amount of food. * **Compliance:** It is critical to **complete the entire prescription** exactly as directed, even if your pet seems completely better. Stopping early can lead to resistant infections. * **Allergic Reactions:** Watch for signs of an allergic reaction, such as facial swelling, hives, rash, or difficulty breathing. Contact your veterinarian immediately if these occur. * **Injection Sites:** If your pet is receiving injectable forms, the injection site may become sore or swollen.
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
- Hypersensitivity reactions (anaphylaxis, urticaria, rash)
- Gastrointestinal upset (anorexia, vomiting, diarrhea) with oral use
- Procaine toxicity (CNS excitement, seizures) in small birds and horses if inadvertently given IV
- Pain or tissue reaction at IM injection sites
注意事項與禁忌
- Known hypersensitivity to penicillins or cephalosporins
- Intravenous administration of Procaine or Benzathine suspension formulations
- Oral administration in horses and hindgut fermenters (rabbits, guinea pigs) due to risk of fatal dysbiosis (unless specifically indicated, e.g., calves with clostridial enteritis)
- Use cautiously in small birds as procaine penicillin may cause procaine toxicity. Do not use oral penicillin therapy in horses for systemic infections (e.g., botulism). Ensure repository forms (procaine/benzathine) are never administered intravenously. Monitor for hypersensitivity reactions. High doses of Penicillin G Potassium given rapidly IV can cause hyperkalemia and cardiac arrhythmias.
藥物相互作用
- Bacteriostatic Antibiotics (e.g., Tetracyclines, Macrolides): May antagonize the bactericidal activity of penicillins, which require actively dividing cells to be effective.
- Aminoglycosides (e.g., Amikacin, Gentamicin): In vivo synergy against certain bacteria; however, physically incompatible if mixed in the same syringe or IV line (inactivation of the aminoglycoside).
- Probenecid: Competitively inhibits renal tubular secretion of penicillins, significantly prolonging their half-life and increasing serum concentrations.
