Symlin

Generic Name: pramlintide (PRAM lin tide)
Brand Names: SymlinPen 120, SymlinPen 60

What is Symlin?

Symlin (pramlintide) is a man-made form of a hormone that occurs naturally in the body. Pramlintide lowers blood sugar in three ways. It slows the rate that food moves from your stomach to your intestines, which keeps your blood sugar from rising too fast. Symlin also lowers the amount of glucose (sugar) your liver produces. Lastly, pramlintide triggers the feeling of fullness after meals to help control your appetite and decrease how much food you eat.

Symlin is used together with insulin to treat type 1 or type 2 diabetes.

Symlin is usually given after other diabetes medicines have been tried without success.

Important information

Do not mix Symlin and insulin together in the same syringe.

You should not use this medicine if you have a digestive condition called "delayed gastric emptying."

Call your doctor if you have severe nausea that lasts for several days. This may be a sign that your dose is too high. If you skip a meal, do not take your dose of Symlin. Wait until your next meal.

You should not use Symlin if you cannot recognize symptoms of low blood sugar. Severely low blood sugar (hypoglycemia) may occur within 3 hours after your Symlin injection. Symptoms may include headache, dizziness, drowsiness, vision problems, hunger, weakness, sweating, confusion, irritability, fast heart rate, or feeling jittery.

Before using this medicine

You should not use Symlin if you are allergic to pramlintide or metacresol, or:

  • if you have a digestive condition called "delayed gastric emptying"; or

  • if you cannot recognize symptoms of low blood sugar.

To make sure Symlin is safe for you, tell your doctor if you have:

  • a history of delayed gastric emptying;

  • problems with vision (blindness, trouble reading);

  • if you are unable to check your blood sugars regularly; or

  • if you have had severe hypoglycemia more than once in the past 6 months.

It is not known whether Symlin will harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant while using this medicine.

It is not known whether pramlintide passes into breast milk or if it could harm a nursing baby. Tell your doctor if you are breast-feeding a baby.

Symlin should not be used in children.

How should I use Symlin?

Use Symlin exactly as it was prescribed for you. Follow all directions on your prescription label. Your doctor may occasionally change your dose to make sure you get the best results. When you first start using Symlin, your insulin dose will change. Do not use your medicines in larger or smaller amounts or for longer than recommended.

Symlin is injected under the skin, at the same time as your insulin injection but in a separate injection. Do not self-inject your medicines if you do not fully understand how to give the injections and properly dispose of used needles and syringes.

Do not mix Symlin and insulin together in the same syringe.

This medicine comes with patient instructions for safe and effective use. Follow these directions carefully. Ask your doctor or pharmacist if you have any questions.

Symlin is usually given just before each major meal. If you skip a meal, you should also skip your Symlin dose.

Use a different place on your stomach or thigh each time you give the injection. Inject your insulin in a separate skin area. Do not inject insulin or Symlin into the same place two times in a row.

Do not use Symlin if it has changed colors or looks cloudy. Call your pharmacist for new medication.

Low blood sugar (hypoglycemia) can happen to everyone who has diabetes. Symptoms include headache, hunger, sweating, confusion, irritability, dizziness, or feeling shaky. Always keep a source of sugar with you in case you have low blood sugar. Sugar sources include fruit juice, hard candy, crackers, raisins, and non-diet soda. Be sure your family and close friends know how to help you in an emergency.

Take care not to let your blood sugar get too low. Severely low blood sugar (hypoglycemia) may occur within 3 hours after your Symlin injection. If you have severe hypoglycemia and cannot eat or drink, use a glucagon injection. Your doctor can prescribe a glucagon emergency injection kit and tell you how to use it.

Also watch for signs of high blood sugar (hyperglycemia) such as increased thirst, increased urination, hunger, dry mouth, fruity breath odor, drowsiness, dry skin, blurred vision, and weight loss.

Check your blood sugar carefully during times of stress, travel, illness, surgery or medical emergency, vigorous exercise, or if you drink alcohol or skip meals. These things can affect your glucose levels and your dose needs may also change. Do not change your dose of Symlin or dosage schedule without your doctor's advice.

Use a disposable needle and syringe only once. Follow any state or local laws about throwing away used needles and syringes. Use a puncture-proof "sharps" disposal container (ask your pharmacist where to get one and how to throw it away). Keep this container out of the reach of children and pets.

Never share an injection pen with another person. Sharing injection pens can allow disease such as hepatitis or HIV to pass from one person to another.

Call your doctor if you have severe nausea that lasts for several days. This may be a sign that your dose is too high.

Symlin is only part of a treatment program that also includes diet, exercise, weight control, regular blood sugar testing, and special medical care. Keep a regular schedule when using your injections and testing your blood sugar. It is also important to plan your meals and physical activity. You may not be able to keep using Symlin if you do not follow the dosing instructions.

If you stop using Symlin for a short time, you may need to restart the medicine at a lower dose. Follow your doctor's instructions.

Storing unopened injection pens: Keep in the carton and store in a refrigerator, protected from light. Throw away any Symlin not used before the expiration date on the medicine label. Do not freeze Symlin, and throw away the medication if it has become frozen.

Take an injection pen out of the refrigerator and allow it to reach room temperature before injecting your dose. Do not remove Symlin from an injector pen and put the medicine in a syringe. You may receive too high a dose.

Storing after your first use: You may keep "in-use" injection pens in the refrigerator or at room temperature. Use within 30 days.
