• > **WARNING**: Primaquine has an extremely narrow therapeutic index in cats. - **Dosing Confusion**: Commercially available human tablets are usually too concentrated for domestic cats. A specialized compounding pharmacy is highly recommended. Prescribers must be explicitly clear whether the dose is based on **primaquine base** or **primaquine phosphate** (26.3 mg primaquine phosphate = 15 mg primaquine base). - **G-6-PD Deficiency**: Contraindicated in humans (and theoretically animals) with Glucose-6-Phosphate Dehydrogenase deficiency due to severe risk of hemolytic anemia. - Avoid use during pregnancy and lactation due to the risk of hemolytic anemia in fetuses/nursing neonates.

藥物相互作用

• Bone Marrow Depressants (e.g., amphotericin B, azathioprine, chloramphenicol, antineoplastics): Concurrent use may cause an increased risk for toxicity and severe myelosuppression.
• Hemolytic Drugs (e.g., acetohydroxamic acid, sulfonylureas, quinidine, sulfonamides): Concurrent use may cause an increased risk for toxicity and hemolysis.
