What is Naproxen Poisoning?

Naproxen is an over the counter NSAID that is used to treat pain, inflammation, and fever in people and dogs. Naproxen has typically been prescribed for dogs at a dose of 2 milligrams per kilogram of body weight every other day. Due to the side-effects, many veterinarians recommend only using naproxen if other medications are ineffective. Naproxen works by blocking the enzyme cyclooxygenase which helps to limit fever and inflammation responses in the body. However, cyclooxygenase also produces prostaglandins that protect the gastrointestinal tract and help with blood flow and filtration in the kidneys. Inhibition of this enzyme can result in bleeding and ulceration of the GI tract as well as reduced kidney function. Dogs have been known to develop vomiting, lethargy and bloody stools after only a single dose of naproxen and week-long regimens often result in signs of kidney dysfunction, especially if they don’t adequately account for the dog’s weight. 

The Animal Poison Control Center had 4,404 reported cases of naproxen poisoning from 2001-2011, both from naproxen that was prescribed to dogs and accidental overdoses of human medication. Single doses as low as 7 mg per kg can have significant symptoms, while 13-15 mg per kg will cause signs of kidney failure with increased blood nitrogen. Gastrointestinal symptoms will become apparent in 2-24 hours, while kidney dysfunction develops in 24-48 hours. Use of other NSAID’s can compound the problem and older dogs with prior kidney disease are also more at risk. Severe overdose can lead to fatal bleeding in the GI tract and acute kidney failure if left untreated. Most symptoms of naproxen poisoning can be resolved with treatment and kidney dysfunction is usually reversible as long as there are no complicating diseases or toxicities.

Naproxen is a non-prescription NSAID that is used to treat fever, inflammation, and pain in humans. It is also prescribed to treat these conditions in dogs, however high doses can have toxic side-effects. Naproxen poisoning in dogs can cause ulcers, gastrointestinal bleeding, and kidney failure.

Symptoms of Naproxen Poisoning in Dogs

Get veterinary treatment as soon as possible if you notice any of the following symptoms associated with naproxen toxicosis.

  • Frequent vomiting (with or without blood)
  • Abdominal pain
  • Lack of appetite
  • Weight loss
  • Lethargy
  • Blood in the stool (melena)
  • Ulcers
  • Pale mucous membranes
  • Weakness
  • Stumbling

Types

These are the brand names for some over-the-counter human medications that contain naproxen.

  • Aleve
  • Anaprox
  • Mediproxen
  • Naprelan
  • Naprosyn

Causes of Naproxen Poisoning in Dogs

These are the most common risk factors associated with naproxen poisoning.

  • High doses of naproxen prescribed to dogs
  • Owners giving naproxen intended for humans to dogs

Accidental overdose of medication for dogs or humans can occur due to :

  • Improperly stored medications
  • Bottle left open
  • Dog chewing through bottle
  • Sugar coated pills that taste good to dogs

Diagnosis of Naproxen Poisoning in Dogs

The veterinarian will physically examine your dog and take blood and urine samples. Blood tests will show regenerative anemia from blood loss as well as increases in BUN (blood nitrogen) and creatinine if kidney failure is present. The veterinarian will need a list of your dog’s current medications and a detailed description of the symptoms. In the case of accidental overdose, bring the empty container or a sample of the medication you think your dog ingested so the veterinarian can evaluate it. The veterinarian will want to know when you think the exposure took place as well as how much your dog may have ingested.

Treatment of Naproxen Poisoning in Dogs

Calling a poison helpline can be a good first treatment for naproxen overdose, especially if you don’t have immediate access to a veterinarian. Have the medication on hand, as well as your dog’s breed and weight. Follow the instructions the agent gives you and get in-person veterinary attention as soon as possible. Only induce vomiting if specifically directed by a professional.

If your dog is developing mild symptoms from a naproxen prescription, the veterinarian will discontinue the medication and treat the symptoms as necessary. Larger doses will require more aggressive treatment. If ingestion that took place in the last 2 hours, the veterinarian will give your dog medication that causes emesis. Activated charcoal may also be given to help limit availability in the gastrointestinal tract and a cathartic medication will help to encourage excretion through bowel movements. A second dose of activated charcoal may be administered 24-48 hours later to limit recirculation from the liver.

Intravenous fluids and electrolytes will help to balance sodium levels which can rise as a result of activated charcoal administration. Various medications may be used to protect the GI tract, including sucralfate, misoprostol, famotidine, or omeprazole. If significant GI bleeding develops, blood transfusions may be necessary to reduce anemia and prevent fatal blood loss. If kidney failure is a possibility, the veterinarian will monitor blood and urine levels and provide fluid treatment as needed to dilute toxins that are normally filtered by the kidneys. Symptoms of naproxen toxicity can continue to increase over a 72 hour period, so the veterinarian will need to monitor your dog during that time. For severe overdose, your dog will need to stay in a veterinary hospital for 3-4 days or until all systems have returned to normal.

Recovery of Naproxen Poisoning in Dogs

Dogs often make a complete recovery after treatment for naproxen poisoning, but there is always a risk of fatal bleeding complications or kidney failure. If your dog is prescribed naproxen, discuss the risk of side-effects with your veterinarian and make sure your dog is on the lowest possible dose. Never give dogs any medications intended for humans. Keep all medications in your house on a high shelf or in a closed medicine cabinet that your dog cannot access. Close all bottles and avoid leaving them around since dogs may be able to access the pills by chewing through the bottle. Sugar coated pills can be an incentive, especially if your dog is already familiar with the taste.

I gave my dog a small dose of Naproxen because I was diagnosed with bronchitis and he has been coughing all day. I thought I may have made him sick.....i have been sick for over a week and he has been by my side the whole time. I thought the naproxen would reduce any inflammation he may have and weighs about 10 pounds. I've only given him the one does....maybe 100 mg about 36 minutes ago. What do I need to do? Please Please help. Im soooo scared i may of hurt my baby.

Please take Fender to see a Veterinarian or Emergency Veterinarian immediately as more than two hours has passed so inducing vomiting wouldn’t help with what has been absorbed already and the dose that Fender has received is a highly toxic dose (20mg/kg) which may lead to kidney failure and possibly death. Fender needs activated charcoal, fluid therapy, symptomatic and supportive treatment. Regards Dr Callum Turner DVM

Naproxen is highly toxic to dogs with one tablet sometime sufficient to cause death in a dog according to some literature; apart from reporting your neighbour to the authorities, it is important to take Egypt to your Veterinarian immediately since you need to consider that on the limited occasions that naproxen is used in dogs (under Veterinary supervision - never give it at home) the dosage is around 1mg/lb meaning that Egypt has had a high quantity of naproxen if only one tablet has been consumed.

My 7lb terrier mix got a hold of a 220mg gel capsule Aleve and managed to pop it. He didn’t ingest the pill and it doesn’t appear that much of the gel leaked out. However it was popped so It worries me that any amount was ingested. This was only about 20 minutes ago and he’s acting completely normal. Do I need to rush to the vet?

Thank you for your question. Naproxen can be highly toxic to dogs, with signs of vomiting, diarrhea, lethargy or importance occurring as a sign of problems. Since he may not have eaten any, you might be fine monitoring him. If you were to be very cautious, he should be seen at your nearest emergency vet and have them induce vomiting and administer activated charcoal to decrease any toxic signs. If you are fairly sure that he ate very little, he should be okay to monitor for any signs of problems.

Naproxen is toxic to dogs even in small doses, I would recommend visiting your Veterinarian or Emergency Veterinarian to be on the safe side as lethargy is a symptom of naproxen ingestion. Naproxen ingestion may lead in severe cases to acute kidney failure and given Shih Poo’s small size in general we should be on the side of caution. Regards Dr Callum Turner DVM

One of my dogs, I have two, just ate through my prescription bottle of Neproxen. Each dose is 375mg, and when I found them, roughly 75% of the pill was gone. I'm not sure which dog ate it, but neither one of them are showing any signs of distress, nor are they acting any differently than they usually do. One dog is a pit bull/lab mix and is 1.5 years old. The other dog is a chihuahua and is 6 months old. Any help is greatly appreciated.

In cases of naproxen poisoning it is best to visit a Veterinarian or Emergency Veterinarian for supportive and symptomatic care. A toxic dose for naproxen in dogs is around 20mg/kg (10mg/lb) so a single tablet can be lethal in a small dog. Whilst symptoms may not occur immediately, ingestion of naproxen can lead to death; vomiting, black tarry stools, weakness and seizures are all symptoms which may occur next.

Any type of poisoning like naproxen or other NSAID (ibuprofen etc…) is concerning, however at this stage fluid therapy and regular monitoring of kidney function and other symptoms (black tarry faeces etc…) is all that can be done. This is serious, but we are looking at monitoring and recovery now; continue with fluid therapy and any medications (gastroprotectants etc…) and have blood and urine tests redone after a week.

If Potato ate a few tablets there is a high risk of toxicity as a single tablet may be enough to cause a poisoning event; since it has been over two hours since ingestion you should visit an Emergency Veterinarian or call the Pet Poison Helpline for further assistance. At this time, inducing vomiting would not work; a visit to a Veterinarian is required as there is a high risk of kidney failure.

Naproxen can be toxic at doses as low as 10mg/lb; I would highly recommend inducing vomiting with 3% hydrogen peroxide and after administering activated charcoal then rushing to your Veterinarian, if you don’t have any hydrogen peroxide just go immediately to your Veterinarian.

Thank you for you email. Unfortunately, you have a tiny dog that ate a huge dose of Naproxen. He needs to be seen by a veterinarian to have him started on IV fluid therapy and stomach protectants. Most clinics offer CareCredit as a form of payment for unexpected emergencies like this. 48 hours later, Chico is at risk for kidney failure and gastric bleeding. I hope that he is okay.

Whilst I understand your financial situation and your difficulty in finding transport, naproxen poisoning in dogs is a severe condition which can lead to kidney failure and death; there is no antidote or special treatment, only aggressive fluid therapy, dietary changes and other supportive care. It would be irresponsible for me to recommend anything other than getting him to a Veterinarian regardless of cost or distance - not everything can be treated at home over the counter. Regards Dr Callum Turner DVM www.petpoisonhelpline.com/poison/naproxen/

hOW MANY milligrams was the pill and how many pills? You said you found 'the pill'If he only had one and it's still a pill then hes likely going to be fine...sounds like he vomited the pill so thats great news, depending on your answer.

he might foam around the mouth...thats a sign of poisoning. you didnt mention that either. ps im not a vet, i just rescued a few poisoned dogs before that drank antifreeze so i lesarned through those. hope it helps

My 2 year old black lab is 89 pounds and got a hold of a bottle of naproxen. I’m not sure of how many pills were in the bottle. There are several pills on the floor that look as if they have been licked. I have no idea if he actually ate any or not. When he doesn’t like the taste of something, he will just spit it out. I’m worried, and I don’t know what to do in this case due to not knowing if he actually ate any or just licked them. What should I do?

Naproxen can be highly toxic in small amounts to dogs, and Jace should see a veterinarian today to have routine blood work done, and most likely go on IV fluids to flush out his system. If he did ingest any of the medication, it can cause kidney failure, and by the time you see signs, it may be too late to treat him. In this situation, it is better to be safe than sorry. I hope that he is okay.
