What is Buprenex for cats?
Buprenex is a commercial brand for buprenorphine for cats. Buprenorphine is an opioid analgesic used to treat pain or as a preanesthetic by professionals. Opioids are strong painkillers that block receptors in the brain and nervous system that signal when a part of the body is injured. These receptors are crucial for survival, as it helps the animal be aware of any damage they have on their bodies. However when treatment is underway or they are recovering from surgery, these sensations are no longer helpful. They are only painful and causes distress.
This is when a professional might prescribe buprenorphine (Buprenex) for you cat. Buprenex will reduce the distress in an injured or post-surgical cat by reducing the messages their brain receives about pain.
What is Buprenex for cats used for?
As we've previously explained, Buprenex is a powerful, long lasting painkiller. Due to this, it can be prescribed in various clinical situations. Although it is primarily used for post operative pain, it is also known to be used in the following situations:
- Post operative analgesia: it is given to cats that have undergone some surgical intervention.
- Pre-operative analgesia: it can also be part of the drugs administered before the operation. It sedates the animal and prepares them for general anaesthesia.
- Chronic pain: buprenorphine is in the second line of action in these cases. However, it can be given with another medication to enhance the effect.
- Acute infections: when other pain relievers are discouraged due to their side effects, Buprenex may be prescribed.

Dosage of Buprenex for cats
Dosages can vary greatly depending on each cat's medical issues, their weight and their general health. It's also important to note that Buprenex is a very strong painkiller and if not properly handled, your cat can overdose. This is why the dosage must be assessed by a professional.
The FDA doesn't provide any information about Buprenex, this is because they have not approved the use of Buprenex for animals. In the UK, however, DEFRA does provide some information on buprenorphine dosage for cats. They state that the typical dose is 10 to 20 micrograms per kg body weight (2,2 lbs).
Nevertheless, it is up to your veterinarian to decide exactly how much Buprenex your cat needs and will receive. For your cat's safety, do not attempt to decide yourself, as there are many factors involved, not only your cat's weight.
