Do you know about 4 types of insulin?



There are Four types of insulin. They vary by onset (how soon they start to work), peak (how long they take to kick into full effect) and duration (how long they stay in your body). If you have to take insulin to treat diabetes, there's good news:
 You have choices. There are FOUR types of insulin

  • Rapid-acting:  Usually taken before a meal to cover the blood glucose elevation from eating.  This type of insulin is used with longer-acting insulin.
  • Short-acting:  Usually taken about 30 minutes before a meal to cover the blood glucose elevation from eating.  This type of insulin is used with longer-acting insulin.
  • Intermediate-acting:  Covers the blood glucose elevations when rapid-acting insulins stop working. This type of insulin is often combined with rapid- or short-acting insulin and is usually taken twice a day.
  • Long-acting:  This type of insulin is often combined, when needed, with rapid- or short-acting insulin.  It lowers blood glucose levels when rapid-acting insulins stop working.  It is taken once or twice a day.
