Naproxen

Naproxen is a non-steroidal anti-inflammatory drug (NSAID) that is used to treat pain and inflammation. It is also used as an antipyretic. Naproxen is an active ingredient contained in various medications, such as Aleve, Naprosyn or Proxen.

When is naproxen used in dogs?

Veterinarians may prescribe naproxen to dogs with joint pain, arthritis and hip dysplasia - a hereditary condition in which the hip ball and socket are loose. This medication can also be prescribed to dogs who have a fever or are fighting an infection due to its antipyretic properties.

How is Naproxen dosed in dogs?

The dosage of naproxen for dogs depends on the severity of the condition, the weight and the breed of the dog. The general recommendation is to administer naproxen orally, initially at a dose of 5 mg/kg body weight, followed by a maintenance dose of 2 mg/kg body weight once daily. The duration of therapy should be as short as possible to minimize the risk of side effects.

What are the side effects of naproxen in dogs?

Like all NSAIDs, naproxen can cause side effects in dogs that can affect the gastrointestinal mucosa, kidney function and blood clotting. The most common side effects include:

  • Vomiting
  • diarrhea
  • loss of appetite
  • bleeding
  • ulcers
  • Kidney damage
  • liver damage

In rare cases, naproxen can also cause allergic reactions, seizures or heart problems. If you notice any signs of overdose or serious side effects in your dog, you should consult a vet immediately.

What are the alternatives to Naproxen for dogs?

Naproxen is not suitable for all dogs, especially those suffering from stomach ulcers, kidney problems or bleeding disorders. In addition, naproxen may interact with other medications your dog is taking, such as corticosteroids, anticoagulants or diuretics. Therefore, you should always consult your vet before giving your dog naproxen.

There are also other NSAIDs that are approved for dogs and may have fewer side effects, such as carprofen, meloxicam or firocoxib. These drugs are specially formulated for dogs and have a longer duration of action than naproxen. However, these NSAIDs can also have side effects and must be administered under veterinary supervision.

Another option is to use natural or herbal remedies that may have anti-inflammatory and pain-relieving properties, such as turmeric, ginger or frankincense. These remedies are generally safer and better tolerated by dogs than synthetic medications. However, you should also ask your vet for advice before using them.

Naproxen is a drug that can relieve pain and inflammation in dogs. However, it must be used with caution and under veterinary guidance as it can have serious side effects. There are also other options that may be more suitable for your dog, depending on their health and needs. That's why it's important to always consult your vet before giving your dog naproxen or any other painkiller.
