葉酸
別名: Folvite, Deplin
藥物類別: Water-Soluble B Vitamin (Vitamin B9)
- **用途：** 葉酸是一種 B 群維生素，用於治療通常由慢性腸道疾病、胰腺問題或長期使用某些抗生素引起的缺乏症。 - **安全性：** 它是一種非常安全的補充劑。因為它是水溶性的，身體很容易將多餘的量從尿液中排出。 - **給藥方式：** 可以與食物一起或空腹給予。請仔細遵循獸醫的指示。 - **長期護理：** 如果您的寵物患有慢性腸道疾病或胰腺外分泌不足，可能需要終身監測維生素水平並定期進行補充治療，以保持牠們的健康。
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
- Severe folate deficiency
- Folate deficiency secondary to exocrine pancreatic insufficiency
- Long-term use of high dose trimethoprim/sulfa (for treating Nocardia)
- Adjunctive therapy in cats with inflammatory bowel disease
- Prolonged therapy with antifolate medications (e.g., trimethoprim, pyrimethamine)
- Severe folate deficiency
- Folate and cobalamin deficiency secondary to inflammatory bowel disease
給藥方式
POIMSCIV
可能的副作用
- Hypersensitivity reactions (rare)
- Gastrointestinal effects (rare)
- CNS effects such as difficulty sleeping, excitement, or confusion (seen only at very high oral doses in humans, e.g., 15 mg/day)
注意事項與禁忌
- Known intolerance or hypersensitivity to folic acid
- Undiagnosed anemias (folic acid therapy may mask the hematologic signs of pernicious anemia/cobalamin deficiency while neurologic damage progresses)
- > **Important:** Do not administer therapeutic doses of folic acid to dogs with enteropathies until baseline serum folate and cobalamin levels have been determined, as dogs may have increased, normal, or decreased folate levels depending on the specific disease process (e.g., bacterial overgrowth vs. malabsorption). - Prolonged folic acid supplementation can potentially decrease serum cobalamin (B-12) levels. - Folic acid is considered very safe during pregnancy (FDA Category A) and lactation. Requirements may actually increase in lactating animals.
藥物相互作用
- Chloramphenicol: May delay the hematologic response to folic acid.
- Methotrexate: Inhibits dihydrofolate reductase; interferes with folic acid utilization.
- Trimethoprim: Inhibits dihydrofolate reductase; interferes with folic acid utilization.
- Pyrimethamine: Inhibits dihydrofolate reductase; interferes with folic acid utilization.
- Phenytoin: Folic acid may decrease serum phenytoin levels, potentially requiring a dosage increase; increased seizure frequency can occur.
- Sulfasalazine: May increase the risk for folate deficiency.
- Barbiturates: May increase the risk for folate deficiency.
- Nitrofurantoin: May increase the risk for folate deficiency.
- Primidone: May increase the risk for folate deficiency.
