Aspirin (Acetylsalicylic Acid) (Bayer Aspirin, Ecotrin)
Dosage form:
Tablets 75 mg, 100 mg, 500 mg
Pharmacological group:
Analgesic / NSAID (COX inhibitor)
Therapeutic use:
Prevention of arterial thromboembolism. Recent data suggest clopidogrel may be superior to aspirin in cats for preventing recurrent cardiogenic thromboembolic events when used as monotherapy. May be used to control mild to moderate pain, though more COX-selective NSAIDs are generally preferred.
Dosage:
Dogs:
Doses are off-label and ideal doses are unknown. Platelet aggregation reduction: 0.5–1 mg/kg orally once every 24 hours, or 0.5 mg/kg every 12 hours. Analgesia, pyrexia, inflammation: 10–20 mg/kg orally every 12 hours; safety and efficacy of this dose have not been established.
Cats:
Platelet aggregation reduction: 18.75 mg per cat orally 3 days per week (low dose) or 75 mg per cat orally 3 days per week (high dose, associated with higher risk of GI side effects). Some authors recommend very low dose (0.5 mg/kg orally once every 24 hours) to inhibit platelet COX without preventing beneficial prostacyclin production. Safety and efficacy of these doses have not been evaluated in clinical or experimental studies.

Calculation formula:
Single dose = (Animal weight × Required dose) ÷ Medication concentration
Important notes:
- Always consult a veterinarian before using any medication.
- Follow the recommended dosage and instructions for use.
Accurate dosing helps protect your pet’s health and reduces the risk of side effects.
