What is SymlinPen 120?
SymlinPen 120 is a man-made form of a hormone that occurs naturally in the body. This medicine 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. This medicine also lowers the amount of glucose (sugar) your liver produces. Lastly, this medicine triggers the feeling of fullness after meals to help control your appetite and decrease how much food you eat.
SymlinPen 120 may also be used for purposes not listed in this medication guide.
You should not use SymlinPen 120 if you have a digestive condition called "delayed gastric emptying."
You should not use SymlinPen 120 if you cannot recognize symptoms of low blood sugar. Severely low blood sugar (hypoglycemia) may occur within 3 hours after your this medicine injection. Symptoms may include headache, dizziness, drowsiness, vision problems, hunger, weakness, sweating, confusion, irritability, fast heart rate, or feeling jittery.

How should I use SymlinPen 120?
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 SymlinPen 120, your insulin dose will change. Do not use your medicines in larger or smaller amounts or for longer than recommended.
SymlinPen 120 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 SymlinPen 120 and insulin together in the same syringe.
SymlinPen 120 comes with patient instructions for safe and effective use. Follow these directions carefully. Ask your doctor or pharmacist if you have any questions.
SymlinPen 120 is usually given just before each major meal. If you skip a meal, you should also skip your this medicine 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 SymlinPen 120 into the same place two times in a row.
Do not use SymlinPen 120 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 SymlinPen 120 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.
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 medication dose or 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.
SymlinPen 120 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 this medicine if you do not follow the dosing instructions.
If you stop using SymlinPen 120 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 SymlinPen 120 not used before the expiration date on the medicine label. Do not freeze this medicine, 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 SymlinPen 120 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.
What happens if I miss a dose?
Take the missed dose as soon as you remember, but only if you are getting ready to eat a meal. Skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up the missed dose.
What happens if I overdose?
What should I avoid while using SymlinPen 120?
Severe hypoglycemia may impair your thinking or reactions, and may result in an injury if you have an accident. Be careful if you drive, operate machinery, or do anything dangerous that requires you to be alert.
SymlinPen 120 can slow your digestion, and it may take longer for your body to absorb any medicines you take by mouth. Avoid taking any oral medicines within 1 hour before or 2 hours after you have used this medicine.
Avoid drinking alcohol. It can lower your blood sugar.
