(pramlintide acetate) injection
Read the Medication Guide and the "Patient Instructions for Use" that come with your SYMLIN product before you start using
it and each time you get a refill. There may be new information. This Medication Guide does not take the place of talking
to your doctor about your medical condition or treatment.
What is the most important information I should know about SYMLIN?
- SYMLIN is used with insulin to lower blood sugar, especially high blood sugar that happens after meals.
- SYMLIN is given at mealtimes. The use of SYMLIN does not replace your daily insulin but may lower the amount of insulin you
need, especially before meals.
- Even when SYMLIN is carefully added to your mealtime insulin therapy, your blood sugar may drop too low, especially if you
have type 1 diabetes. If this low blood sugar (severe hypoglycemia) happens, it is seen within 3 hours after a SYMLIN injection.
Severe low blood sugar makes it hard to think clearly, drive a car, use heavy machinery or do other risky activities where
you could hurt yourself or others.
- SYMLIN should only be used by people with type 2 and type 1 diabetes who:
- already use their insulin as prescribed, but still need better blood sugar control.
- will follow their doctor's instructions exactly.
- will follow up with their doctor often.
- will test their blood sugar levels before and after every meal, and at bedtime.
- understand how to adjust SYMLIN and insulin doses.
What is SYMLIN?
SYMLIN is an injectable medicine for adults with type 2 and type 1 diabetes to control blood sugar. SYMLIN slows down the
movement of food through your stomach. This affects how fast sugar enters your blood after eating. SYMLIN is always used
with insulin to help lower blood sugar during the 3 hours after meals.
Who should not use SYMLIN?
Do not use SYMLIN if you:
- cannot tell when your blood sugar is low (hypoglycemia unawareness).
- have a stomach problem called gastroparesis. This is when your stomach does not empty as fast as it should.
- are allergic to SYMLIN or any ingredients in SYMLIN. See the end of this Medication Guide for a complete list of ingredients.
SYMLIN has not been studied in children.
What should I tell my doctor before starting SYMLIN?
Tell your doctor about all of your medical conditions including if you:
- are pregnant or planning to become pregnant. It is not known if SYMLIN can harm your unborn baby. You and your doctor will decide how to best control your blood sugar
levels during pregnancy.
- are breastfeeding. It is not known if SYMLIN passes into your milk and if it can harm your baby. You and your doctor will decide the best way
to feed your baby if you are using SYMLIN.
Keep a list of all the medicines you take. Tell your doctor about all the medicines you take including prescription and non-prescription
medicines, vitamins, and herbal supplements. SYMLIN can slow down how other medicines pass through your stomach and may affect how much of them get into your body. You
may have to change the times you take certain medicines.
How should I use SYMLIN?
- You must use SYMLIN exactly as prescribed. The amount of SYMLIN you use will depend on whether you have type 2 or type 1
diabetes. You and your doctor will decide if you can use SYMLIN.
- It is important for you to carefully read, understand and follow the "Patient Instructions for Use" that comes along with
this Medication Guide and your SYMLIN.
- SYMLIN is available in vials and two SymlinPen® pen-injectors. Your doctor will prescribe the type of SYMLIN that is right for you.
- If you have been using the SYMLIN vial with an insulin syringe and you are changing to the SymlinPen® pen-injector: Your doctor will prescribe the SymlinPen® pen-injector that is right for you, tell you how much SYMLIN to inject and when to inject it.
- It is important that you understand how to inject the right SYMLIN dose. Read the "Patient Instructions for Use" carefully
BEFORE giving your first dose with the SymlinPen® pen-injector. The SYMLIN in the pen-injector is a different strength than the SYMLIN in the vial.
- The way you inject SYMLIN is similar to the way you inject insulin. Inject SYMLIN under the skin (subcutaneously) of your stomach area (abdomen) or upper leg (thigh). Inject SYMLIN at a site that is more than 2 inches away from your insulin injection. Do not inject SYMLIN and insulin in
the same site.
- To help reduce the chances of getting a reaction at the injection site, allow SYMLIN to come to room temperature before injecting.
- Use a new needle for each SYMLIN injection.
- Never mix SYMLIN and insulin. Insulin can affect SYMLIN when the two are mixed together.
- Do not use SYMLIN if the liquid looks cloudy.
- If you take more than your prescribed dose of SYMLIN, you may get nauseous or vomit, and you may not be able to eat the amount
of food you usually eat. If you take more SYMLIN than your prescribed dose, pay careful attention to the amount of insulin
you use because you may be at more risk for low blood sugar. Contact your doctor for guidance.
- If you miss or forget a dose of SYMLIN, wait until the next meal and take your usual dose of SYMLIN at that meal. Do not take more than your usual dose of SYMLIN.
