* **給藥方式：** 請將此藥物與食物一起餵食或直接混入寵物的食物中，以減少腸胃不適並提高療效。 * > **重要警告：** 請勿給幼貓服用，並確保幼貓無法接觸到已添加此藥物的成貓食物。 * **飲食注意事項：** 除非獸醫師特別指示，否則請勿將此藥物與處方泌尿道飲食（如 s/d 或 c/d）合併使用，因為這可能導致血液酸鹼值發生危險的變化。 * **何時應聯繫獸醫：** 如果您的貓咪出現虛弱、食慾不振、走路不穩或牙齦蒼白/發紺等症狀，請立即聯繫您的獸醫師。
劑量必須由獸醫依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
- Urine acidification
- Urine acidification
- General / Ketosis
- Laminitis (purported)
- Senecio-induced liver damage
- Urine acidification (struvite dissolution)
- Struvite dissolution therapy (if diet and antimicrobials do not result in acid urine)
給藥方式
POIVtopical
可能的副作用
- Gastrointestinal distress (nausea, vomiting)
- Heinz-body hemolytic anemia (especially in cats)
- Methemoglobinemia
- Ataxia
- Cyanosis
- Metabolic acidosis
- Gastrointestinal upset (nausea, vomiting, diarrhea)
- Heinz body anemia (especially in cats at high doses)
- Worsening of hepatic encephalopathy in patients with liver disease
注意事項與禁忌
- Renal failure
- Pancreatic disease
- Hepatic insufficiency
- Preexisting acidosis
- Oxalate or urate calculi
- Kittens
- Pre-existing metabolic acidosis
- Severe liver disease or hepatic encephalopathy
- Urate, cystine, or calcium oxalate urolithiasis
- Young growing animals
- Pregnant or nursing animals
- > **Hepatic Warning:** If used in patients with frank hepatic insufficiency, methionine can cause increased production of mercaptan-like compounds and intensify the signs of **hepatic encephalopathy** (dementia or coma). * **Urolithiasis Risk:** Do not give to animals with oxalate or urate calculi, as these stones thrive in acidic environments. * **Dietary Overlap:** Unmonitored use concurrently with an acidifying diet (e.g., s/d, c/d) may easily lead to severe metabolic acidosis and signs of overdose. * **Age Restrictions:** Strictly not recommended for use in kittens due to high susceptibility to toxicity.
藥物相互作用
- Aminoglycosides (gentamicin, amikacin): Urine acidification may diminish the effectiveness of aminoglycosides in treating bacterial urinary tract infections, as they are more effective in an alkaline medium.
- Erythromycin: Urine acidification may diminish the effectiveness of erythromycin in treating bacterial urinary tract infections.
- Quinidine: Urine acidification may increase the renal excretion of quinidine, potentially lowering its systemic levels.
- Other urinary acidifiers (e.g., ammonium chloride): Additive acidification leading to severe metabolic acidosis
- Urinary acidifying diets: Excessive lowering of urine pH and increased risk of metabolic acidosis
