Humulin N vs. Novolin N: A Side-by-Side Comparison

Humulin N Vs. Novolin N: A Side-By-Side Comparison

The first thing to understand when it comes to comparing two drugs is that they have different effects on your dog’s health. They both work, but there are some differences between them. For example, if you were using one drug for arthritis, the other would probably be better for joint pain or even diabetes (which affects blood sugar levels). So let’s take a look at how each drug works for various conditions.

Dogs with Diabetes

There is evidence that suggests that the use of insulin may improve diabetic dogs’ health. However, because diabetes is such a complex disease, there isn’t enough research yet to say whether it improves the overall quality of life for these animals.

If you’re worried about your diabetic dog having problems, it might be best to avoid using either drug. If you do decide to use one of these drugs, make sure you give him plenty of exercise and don’t forget to monitor his blood sugar regularly.

Osteoporosis in Dogs

While there isn’t much research into osteoporosis in dogs, there is some evidence that suggests that the use of vitamin D3 supplements may reduce bone loss in older dogs. If you’re worried about your dog’s bone health, be sure to ask your vet whether or not this is a problem. If it is, they will be able to tell you whether or not a supplement would be useful.


If you don’t already know, insulinomas are a very common form of cancer that occur in dogs. These tumors develop in the pancreas and release an excessive amount of insulin into the dog’s body. This can cause several health problems, such as low blood sugar (hypoglycemia), seizures, and even death.

When it comes to treating these tumors, vets usually only recommend surgery if they are 1 cm or larger in size. They also usually recommend using insulin when the tumors start to grow again or if they begin to bleed. There is also some evidence that suggests that administering anti-seizure drugs after a tumor has been removed may prevent the dog from having more seizures.

Insulinomas can be very serious, but they can be treated effectively if you keep your eye on the condition of your dog.

Older Dogs

One thing that many owners of older dogs like to do is switch from brand name prescription drugs to generic alternatives. The reasons for doing this are fairly obvious: the brand name drugs can be quite expensive. Unfortunately, this may not be the best solution if you’re trying to save money.

An analysis that was recently carried out on several drugs showed that many of the generic alternatives are not as pure as their brand name equivalents. For these drugs, the impurity means that they can’t work as well to treat your pet’s condition.

Now, there are some drugs where this is not an issue. If you’re giving your dog something like amoxicillin, then a generic equivalent should be just as effective as the branded version.

However, if your dog needs something likecefovecin (an antibiotic used to treat skin infections), then you may want to consider staying with the brand name treatment. The generic version of this drug was shown to be four times less pure than the brand name drug.

Hopefully, animal drug manufacturers will be able to create equally effective but cheaper alternatives in the future. In the meantime, you’ll just have to decide whether or not you want to pay the extra money for brand name drugs.

Dealing with Canine Arthritis

Arthritis is the inflammation of one or more joints in your pet’s body. It’s usually caused by an old injury, but it can also be a result of normal wear and tear on the cartilage in his joints.

In dogs, the most common type of arthritis is osteoarthritis. This is the same type of arthritis that affects humans, and it usually makes itself known in dogs around the age of nine or ten. While some breeds are more prone to the condition (Bentley, you’re looking at your Norwegian Elkhound ancestors), there isn’t a breed of dog that’s exempt from the condition.

The symptoms of canine arthritis can vary from dog to dog. Some dogs may experience a little stiffness in their joints, while others may not be able to walk at all. The most common areas that canine arthritis effects are the spine, hips, and feet. Because of this, there are several treatments that your veterinarian may recommend.

Anti-Inflammatory Drugs

The first group of drugs that your veterinarian may suggest are anti-inflammatory drugs. Drugs in this group can help to alleviate some of the pain by reducing the swelling around the joints. The most common types of drugs in this group are:

NSAIDs – ibuprofen is a perfect example of this type of drug

Aspirin-based drugs, including buffered aspirin


Glucocorticoid drugs

These drugs are usually only recommended if the pain is severe. Otherwise, your veterinarian may suggest more long-term treatments.

Weight Control

One of the other things that you can do for your dog is to make sure that he maintains an ideal weight. Just like with humans, excess weight on a dog can increase the strain on joints and make the pain much worse. Your veterinarian can recommend a special diet for your dog that will help him lose weight if he needs to. Don’t force your dog to exercise if he shows signs of pain, but do make sure that he gets enough exercise to keep his muscles toned and his body healthy.


Another drug that your veterinarian may suggest is called Cartrophen. This injectable medication is a synthetic version of the naturally occurring drug, meloxicam. Meloxicam works by affecting the way in which the brain senses pain. This means that it can help to alleviate the pain that your dog may experience in his joints.

The main advantage of this drug is that it can be easily given to your dog as an injection. In some cases, it can even be given right at home. The disadvantage is that it’s very expensive, and only available through veterinarians. Not all dogs respond to it equally either.

Some may experience a dramatic reduction in pain, while others may not experience much of a change at all.


If none of the above treatments are effective, or if your dog is in a great deal of pain, your veterinarian may suggest surgery. In this procedure, the painful joint is removed completely. This usually only happens if all other treatments have failed, or if the pain is so bad that your dog isn’t able to enjoy a good quality of life anymore.


The prognosis for dogs with arthritis is fairly good. Most dogs can recover from their symptoms with the right combination of medications and lifestyle changes. Dogs who have arthritis that affects more than three joints may not respond completely to treatment, but most will still benefit from it. Arthritis that involves the spinal joints usually results in chronic pain, and its unlikely that your dog will ever experience relief from it.

However, with early detection and treatment many dogs live happy and active lives for years to come. Even when arthritis is more advanced, most dogs can still lead a good life if they get the right combination of therapy and medication.

Note: Don’t automatically choose the “cheap” medication just because it’s cheaper. There is no such thing as a good generic for medications, and you should always ask your veterinarian which medicines are best. Sometimes the most expensive medication is the best one for your dog, but this isn’t always the case.
