Medications for Type 1 Diabetes
by Cynthia M. Johnson, MA
Insulin is the main medicine used to treat type 1 diabetes. Pramlintide may be used with it. Here are the basics about each of these medicines. Only common problems with them are listed.
Insulin is injected 2 to 4 times during the day to replace the insulin that the pancreas cannot make. It is often given before meals, at snacks, and at bedtime. The amount of insulin must be balanced with the amount and type of food that is eaten and the amount of activity that is done. Making changes to a person's diet, exercise, or both without making changes to the insulin dose can cause blood glucose to drop too low or rise too high.

Amylin is a hormone made by the same beta cells that make insulin. Pramlintide is chemically related to amylin. It lowers blood glucose when used with insulin. It is given to people who cannot manage blood glucose with insulin alone.
Pramlintide is injected right before meals. It can lower appetite and result in weight loss. This can be helpful to those who need to reach a healthy weight and those who have gained weight as a side effect of using insulin.
