Hydrogen Peroxide 3%
Also known as: Hydrogen Peroxide 3% Solution
> **EMERGENCY USE ONLY:** Never induce vomiting without first consulting your veterinarian or a Pet Poison Control Center. Some toxins (like batteries, bleach, or sharp objects) cause severe damage if vomited back up! * **Use the Right Product:** Ensure you are using standard **3% hydrogen peroxide**. Higher concentrations (like hair dye developer) are extremely dangerous and corrosive. * **Administration:** Use a dosing syringe or turkey baster to squirt the liquid into the side of the mouth. Do not force it down the throat to avoid your pet inhaling the liquid into their lungs. * **Pro Tip:** Feeding a small, moist meal (like a slice of bread or a little canned food) right before giving the peroxide can give the stomach something to push against and improve the chances of vomiting. Walking your dog around after giving the dose can also help mix the peroxide in the stomach. * **Aftercare:** Watch your pet closely. Do not let them re-eat the vomit. Collect a sample of the vomit in a plastic bag or container for your vet to examine.
Dosage must be set by your veterinarian for your specific pet. Never give human medication or another pet’s prescription without veterinary guidance.

How it is given
Possible side effects
- Aspiration of hydrogen peroxide solution or stomach contents
- Vasovagal (bradycardic) response in animals with cardiovascular compromise
- Gastric ulceration (particularly in cats)
- Gastric-dilatation-volvulus (GDV) in dogs
Cautions & contraindications
- Animals already vomiting
- Severely lethargic, comatose, or debilitated animals (e.g., respiratory distress, decreased swallowing reflex, bradycardia)
- Seizuring or hyperactive animals
- Recent abdominal surgery
- Megaesophagus
- Ingestion of corrosives/caustics (e.g., acids, alkalis)
- Ingestion of sharp objects
- Ingestion of bagged illicit drugs
- Ingestion of hydrocarbons or petroleum distillates
- Rodents or rabbits (incapable of vomiting)
- > **WARNING:** Do not induce emesis in animals that lack a normal swallowing reflex or are severely depressed due to high aspiration risk. * **Neurological Status:** Use caution when attempting to induce emesis in a dog that has ingested a compound that can cause seizures or CNS depression, as CNS status may rapidly deteriorate. * **Timeframe:** Administration and emesis generally must occur within 4 hours (some say 2 hours or 6 hours maximum) of the toxic ingestion. * **Product Safety:** If home administration is necessary, ensure clients use ONLY the 3% medical grade solution. Higher concentrations are highly corrosive. * **Monitoring:** Because aspiration and/or bradycardia are possible, animals should be closely observed. Suctioning, respiratory, and cardiovascular support (e.g., **atropine**) should be available in a clinical setting. * **Re-ingestion:** Do not allow the animal to re-ingest vomitus.
Drug interactions
- ACETYLCYSTEINE (oral): Hydrogen peroxide can oxidize acetylcysteine in the gut; alternative emetics are preferred for acetaminophen overdoses.
- ANTIEMETICS (e.g., ondansetron, maropitant): Preadministration or ingestion of these products may negate the emetic effects of hydrogen peroxide.
