Qué hacer ahora mismo
- 1
Gather All Medication Information
Bring the pill bottle: drug name, strength (mg), number of pills missing. Calculate total mg consumed: strength × pills. This is critical for toxicity assessment.
- 2
Call Poison Control IMMEDIATELY
ASPCA Poison Control: (888) 426-4435. Do NOT wait for symptoms — some medications cause delayed toxicity.
- 3
Do NOT Induce Vomiting Without Professional Guidance
Some medications are rapidly absorbed; others can cause seizures if vomited. Only induce if ASPCA or your vet instructs you to.
- 4
Go to Emergency Vet for Decontamination
Your vet will induce vomiting (if early), administer activated charcoal, and begin IV fluids. Blood work will monitor liver/kidney function for 24-72 hours.
La ciencia detrás de esto
Los perros metabolizan muchos fármacos de manera diferente a los humanos. Los AINE (ibuprofeno) inhiben las enzimas ciclooxigenasa, reduciendo las prostaglandinas protectoras en el tracto GI y los riñones, causando úlceras e insuficiencia renal. El acetaminofén agota el glutatión en los hepatocitos caninos y convierte la hemoglobina en metahemoglobina, afectando el transporte de oxígeno. Los perros son particularmente sensibles a muchos medicamentos para TDAH (anfetaminas) debido a su efecto sobre la liberación de catecolaminas. Incluso suplementos "inofensivos" como la vitamina D pueden causar hipercalcemia fatal cuando se ingieren en grandes cantidades (ASPCA, 2023).
Calculadora de dosis tóxica
Cantidad ingerida: Depende del fármaco: Ibuprofeno 50mg/kg, Acetaminofén 75mg/kg, una sola pastilla de algunos medicamentos para TDAH
LD50: Ibuprofeno: 100mg/kg (fatal), Acetaminofén: 150mg/kg (Fuente: ASPCA)
La ciencia detrás de esto: Centro de Control de Intoxicaciones Animales de ASPCA, 2023
Una sola tableta de ibuprofeno de 200 mg puede causar insuficiencia renal en un perro de 4 kg. Cinco tabletas (1000mg) = 250mg/kg = dosis potencialmente fatal.
Cronograma de síntomas: qué esperar
Best window for induced vomiting. Call poison control before inducing.
Drug absorption phase. Symptoms begin for fast-acting drugs (ibuprofen): vomiting, abdominal pain.
GI ulceration phase (NSAIDs). Symptoms: bloody vomiting, black tarry stool, kidney stress begins.
Organ damage phase: liver failure (acetaminophen), kidney failure (NSAIDs), seizures (antidepressants). Hospitalization required.
Preguntas frecuentes
Which human medications are most toxic to dogs?
The most dangerous human medications for dogs include: (1) NSAIDs (ibuprofen, naproxen) — GI ulcers and kidney failure at 50mg/kg. (2) Acetaminophen (Tylenol) — liver damage and methemoglobinemia at 75mg/kg. (3) Antidepressants (SSRIs, SNRIs) — serotonin syndrome. (4) ADHD medications (amphetamines) — severe stimulation. (5) Benzodiazepines — paradoxical agitation. (6) Vitamin D supplements — fatal hypercalcemia.
What are the symptoms of ibuprofen poisoning in dogs?
Symptoms appear within 1-4 hours: vomiting (possibly with blood), loss of appetite, abdominal pain, and diarrhea. At toxic doses (50mg/kg+): kidney failure (increased thirst/urination, then decreased urine), GI ulceration, liver damage, and seizures. Megaesophagus (enlarged esophagus) can occur with chronic exposure. Treatment includes activated charcoal, gastroprotectants, IV fluids, and blood monitoring.
Should I induce vomiting if my dog ate medication?
Inducing vomiting may be recommended if ingestion occurred within 30 minutes and your dog is alert. However, do NOT induce vomiting for: caustic substances, if your dog is already symptomatic (seizures, ataxia), or if the medication is rapidly absorbed. Call ASPCA Poison Control at (888) 426-4435 with the drug name, strength, and estimated number of pills consumed.
How is medication toxicity treated in dogs?
Treatment depends on the drug: (1) Induced vomiting + activated charcoal (if early), (2) IV fluids for elimination, (3) Gastroprotectants (omeprazole, sucralfate) for NSAIDs, (4) N-acetylcysteine for acetaminophen, (5) Cyproheptadine for serotonin syndrome, (6) Lipid emulsion therapy for fat-soluble drugs. Hospitalization for 24-72 hours is typical for significant ingestions.
