Previcox for Dogs: Benefits, Dosage, Safety and MorePrevicox, with the active ingredient firocoxib, is a chewable non-steroidal anti-inflammatory drug (NSAID) that is used as a painkiller for dogs suffering from osteoarthritis.

Your dog and you have been inseparable from the moment you first laid eyes on each other.

He shares your bed, your food and your passion for fishing.

You share your secrets with him because you know they’re safe with him, and he loves you unconditionally because he knows he’s safe with you. But recently you’ve noticed he’s not that keen on afternoon runs, and instead of following you to your room, he lies at the bottom of the staircase.

Even though he still has a twinkle in his eyes, he no longer has that spring in his step.

Your pup is getting older, and he’s probably suffering from osteoarthritis, a degenerative joint disease or DJD that affects both humans and animals.

The condition refers to the chronic joint inflammation that’s caused by the gradual deterioration of joints. It affects older dogs and causes extreme pain and discomfort.

Unfortunately, there is no cure for the debilitating condition, but there are ways to keep your dog comfortable, manage the pain and inflammation and slow down the disease’s progression.

What is Previcox?

As we stated above – Previcox, with the active ingredient firocoxib, is a chewable non-steroidal anti-inflammatory drug (NSAID) that is used as a painkiller for dogs suffering from osteoarthritis.

It also works to block the chemical messengers that are responsible for causing inflammation, swelling, and pain.

What are the Benefits of Previcox?

Osteoarthritis causes pain and inflammation and usually affects the elbows, wrists, hip, knees, and spine.

As it advances, these areas become less flexible,  more inflamed, and more painful. Previcox helps relieve the pain and reduces lameness and limping. The NSAID is also prescribed for post-operative pain, specifically for dogs that have undergone orthopedic surgery. Other benefits include:

  • Fast acting with rapid results
  • Chewable tablet with pleasant BBQ flavor
  • Can be given with or without food
  • Suitable for dogs that weigh more than 12.5 pounds

Symptoms of Osteoarthritis

Osteoarthritis can present itself in various ways. If you suspect your dog is experiencing the onset of this disease, look out for the following symptoms:

  • Stiffness, most noticeable just after he’s woken up
  • An abnormal gait
  • Sensitivity when the affected joints are touched
  • Licking around joint areas
  • Lack of interest or reluctance to walk, play, climb stairs, jump on furniture and even a reluctance to stand

It’s important to note that some of these symptoms could be as a result of other health problems. Either way, an appointment with your vet is important.

Important Things to Discuss with your Vet before Giving your Dog Previcox

Once osteoarthritis has been diagnosed, your vet will be able to discuss treatment options as well as lifestyle and diet changes your dog will need.

As already mentioned, there is no cure for osteoarthritis, however, there are a number of ways you can effectively manage the pain, and keep your dog comfortable.

Dog Previcox is an effective treatment for osteoarthritis, however, there are a number of risks that are associated with it.

Before your vet prescribes this anti-inflammatory medicine, it’s important to talk to him about your dog’s medical history, any allergies or allergic reactions to other non-steroidal anti-inflammatories including aspirin, and the physical condition of your dog.

Your vet should also discuss the side-effects of Previcox, as well as adverse reactions, and possible signs of overdose.

Talk to your vet about the diagnosis:

  • The role diet and weight management plays in terms of managing the condition
  • How often your dog will need to see the vet
  • The benefits and risks of Previcox

Tell your vet if your dog has ever experienced any medical issues including:

  • Liver disease
  • Kidney disease

Discuss current medications your dog might be taking as well as any allergic reactions:

  • Mention any allergies your dog has had in the past, especially to NSAIDs and aspirin
  • Mention all the medicines you give your dog, including nutritional supplements and over the counter medicines

Talk to your vet about your dog’s physical condition:

  • Is pregnant, lactating or if you’re planning to breed with your dog
  • Is under seven months

Previcox Dosage

Previcox is a chewable tablet that is given by mouth. The tablets are scored in case they need to be split. Your veterinarian will work out the correct dosage based on your dog’s weight and will advise how it should be administered.

It’s best to use the lowest dosage for the shortest time and the recommended dose is 2.27 milligrams per pound.

The medication is usually given once a day, with or without food. However, giving it with food will reduce the risks of diarrhea and vomiting, as well as more serious conditions like ulcers or gastrointestinal bleeding.

The tablet has a pleasant BBQ taste which makes administering easy. You can place it in your dog’s mouth or he will take it straight from your hand.

Should you miss a dose, give it as soon as possible but if it’s time for the next tablet, skip the one you missed and administer it as per the schedule.

Never give your dog two tablets at once.

For dogs undergoing orthopedic surgery, Previcox is prescribed for three days as is necessary to reduce inflammation and pain. In some instances, it is given a few hours before surgery.
