For those with type 1 and type 2 diabetes, the body does not produce enough insulin or use it to properly to manage blood glucose levels. As a result glucose accumulates in the blood stream which can eventually lead to serious health complications or death.

Diabetics will typically require insulin to be injected under the skin (subcutaneously) which helps move glucose from the blood into other body tissues where it can be used as energy.

Modern insulin products such as NovoRapid (NovoLog) are improved versions of human insulin.

What is the NovoRapid FlexPen?

NovoRapid® (known as NovoLog in the US) FlexPen® 100 U/ml Solution was developed by the company Novo Nordisk.

Typically the FlexPen starts working 10-20 minutes after injection, a maximum effect occurs between 1 to 3 hours and lasts up to 3-5 hours. Due to it’s short onset of action, this insulin is usually combined with an intermediate-acting or long-acting insulin preparations.

Insulin should be taken at least 5-10 minutes prior to meals or within 20 minutes after starting your meal.

NovoRapid® can be used in children instead of soluble human insulin when a rapid onset effect is preferred. For example, when it is difficult to dose the child in relation to meals.

Before administering insulin, clean the surface area of the injection site to prevent an infection.

The dose requirement for NovoRapid is usually between 0.3 and 1.0 IU/kg per day.

Hypoglycamia (low blood sugar)

Hypoglycemia (or hypo for short) can be experienced if your blood sugar drops too low.

This may happen if:

  • you skip a meal or eat too little
  • you exercise more than usual

Warning signs of hypoglycemia may include:

  • cold sweats
  • cool pale skin
  • hunger
  • changes in vision
  • drowsiness or tiredness
  • weakness
  • nervousness
  • feeling ill
  • rapid heart beat
  • headaches

  • confusion
  • difficulty concentrating

If you feel an episode of hypoglycemia coming on consume a glucose tablet, sugary snack (hard candy, jelly beats, biscuits) or sugary beverage such as fruit juice or pop (non diet). Always carry these with you just in case you experience a hypo.

When symptoms of hypoglycemia have gone away consume a snack. When blood sugar levels have stabilized continue insulin treatment as usual.

Educate family and friends on what to do if you experience a severe hypoglycemic episode and lose consciousness. They must not give you any food or drink if you are unconscious as you make choke.

If you lose consciousness, a trained family or friend must administer an injection of the hormone glucagon. Once you regain consciousness you must consume a sugary snack.

If you do not respond to the glucagon treatment you should be taken to the hospital immediately where they need to find the reason for your hypos.

If hypoglycemia is not treated it can lead to temporary or permanent brain damage, or even death.

If you are experiencing hypos regularly, your doctor may need to adjust your insulin regimen such as timing and dosage; and life style (diet and exercise).

Hyperglycemia (sugar levels are too high)

If sugar levels are too high, patients may experience hyperglycemia.

  • dry skin
  • dry mouth and fruity (acetone) breath

Hyperglycemia may lead to a very serious condition called ketoacidosis which is a build up of acid in the blood. This happens when the body breaks down fats instead of sugar.

If untreated, can result in diabetic coma and eventually death.

If you experience any of the symptoms mentioned above, it’s important that you monitor blood glucose levels regularly and urine for ketones and share results with your doctor.

If you stop taking medication this can lead to severe hyperglycemia. Do not stop taking medication without consulting your doctor first who can provide guidance for managing diabetes complications.
