Inducing Vomiting Guidelines

## Inducing Vomiting in Pets — First Aid Guidelines

Inducing vomiting can be a critical first aid measure after toxin ingestion, but it must be done correctly and only in appropriate situations. Incorrect use can cause aspiration pneumonia, esophageal burns, or worsen the poisoning.

> **⚠️ IMPORTANT:** Always contact your veterinarian, emergency animal hospital, or the ASPCA Animal Poison Control Center (888-426-4435) BEFORE inducing vomiting. Not all ingestions warrant vomiting, and some substances cause more damage coming back up.

## When Inducing Vomiting MAY Be Appropriate

Vomiting may be recommended by a veterinarian when:

- The ingestion occurred within the last **1-2 hours** (stomach has not yet emptied)
- The substance is **not caustic or corrosive** (no bleach, drain cleaner, or petroleum products)
- The pet is **fully conscious and alert** (not drowsy, seizing, or wobbly)
- The substance is **not sharp** (no bones, glass, or pointed objects)
- The pet is a **dog** (inducing vomiting in cats is more dangerous and rarely recommended at home)

## When You Should NEVER Induce Vomiting

Do NOT induce vomiting if your pet has ingested:

- **Caustic or corrosive substances** (acids, alkalis, bleach, oven cleaners) — these burn twice
- **Petroleum products** (gasoline, kerosene, motor oil) — high aspiration risk
- **Sharp objects** (needles, glass, bones) — can perforate the esophagus
- Also do NOT induce vomiting if the pet is:
- Already vomiting
- Unconscious, heavily sedated, or seizing
- Having difficulty breathing
- A brachycephalic breed (higher aspiration risk — Bulldogs, Pugs, etc.)

## How Veterinarians Induce Vomiting

**In dogs (veterinary-guided home method):**
- **3% hydrogen peroxide** is the only at-home emetic recommended for dogs
- Dose: 1 teaspoon (5 mL) per 10 pounds of body weight, maximum 3 tablespoons (45 mL)
- Administer orally with a syringe (no needle) aimed at the back of the tongue
- Walk the dog gently afterward — movement helps stimulate vomiting
- Vomiting usually occurs within 10-15 minutes
- If no vomiting after 15 minutes, ONE repeat dose may be given
- If still no vomiting, proceed to the emergency vet immediately

**In a veterinary clinic:**
- **Apomorphine** (injection or eye tablet) is used for dogs — faster and more reliable
- **Dexmedetomidine** or **xylazine** may be used for cats under veterinary supervision
- Activated charcoal may be given after vomiting to absorb remaining toxins

## Critical Safety Warnings

- **NEVER use salt, mustard, ipecac syrup, or dish soap** — these can cause dangerous toxicity themselves
- **NEVER use hydrogen peroxide in cats** — it can cause severe hemorrhagic gastritis and esophageal necrosis
- **Do NOT induce vomiting more than twice** — proceed to the vet after two failed attempts
- **Save the vomit** for your veterinarian to examine — this helps identify the substance and quantity

## What to Bring to the Vet

When heading to the emergency vet after a toxin ingestion:

1. The packaging or label of the ingested product
2. An estimate of how much was consumed
3. The time of ingestion
4. Any vomit produced (in a sealed container)
5. Your pet's weight and any medications they take

## After Vomiting Occurs

- Do NOT feed your pet for 2-4 hours after vomiting
- Offer small amounts of water after 1 hour
- Monitor for continued vomiting, lethargy, diarrhea, or tremors
- Follow up with your veterinarian even if vomiting was successful — some toxins require additional treatment

## Prevention Is Best

- Store all medications, chemicals, and toxic foods securely out of pet reach
- Use child-proof locks on cabinets containing household chemicals
- Keep the ASPCA Poison Control number saved in your phone: **888-426-4435**
- Consider pet insurance that covers emergency visits and poison control consultations
