Brand Name(s): Symlin Pen®
IMPORTANT WARNING:
You will use pramlintide with mealtime insulin to control your blood sugar levels. When you use insulin, there is a chance that you will experience hypoglycemia (low blood sugar). This risk may be greater during the first 3 hours after you inject pramlintide, especially if you have type 1 diabetes (condition in which the body does not produce insulin and therefore cannot control the amount of sugar in the blood). You may harm yourself or others if your blood sugar drops while you are involved in an activity that requires you to be alert or to think clearly. Do not drive a car or use heavy machinery until you know how pramlintide affects your blood sugar. Talk to your doctor about what other activities you should avoid while you are using pramlintide.
Tell your doctor if you have had diabetes for a long time, if you have diabetic nerve disease, if you cannot tell when your blood sugar is low, if you needed medical treatment for hypoglycemia several times in the past 6 months, or if you have gastroparesis (slowed movement of food from the stomach to the small intestine. Your doctor will probably tell you not to use pramlintide. Also tell your doctor if you are taking any of the following medications: angiotensin converting enzyme (ACE) inhibitors used to treat high blood pressure, heart disease, or diabetic kidney disease; beta blockers such as atenolol (in Tenoretic), labetalol (Trandate), metoprolol (Lopressor, Toprol XL, in Dutoprol, in Lopressor HCT), nadolol (Corgard, in Corzide), and propranolol (Hemangeol, Inderal, Innopran, in Inderide); clonidine (Catapres, Duraclon, Kapvay, in Clorpres); disopyramide (Norpace); fenofibrate (Antara, Lipofen, Tricor, others); fluoxetine (Prozac, Sarafem, Selfemra, in Symbyax); gemfibrozil (Lopid); guanethidine (Ismelin; no longer available in U.S.); other medications for diabetes; lanreotide (Somatuline Depot); monoamine oxidase (MAO) inhibitors such as isocarboxazid (Marplan), phenelzine (Nardil), selegiline (Eldepryl, Emsam, Zelapar), and tranylcypromine (Parnate); pentoxifylline (Pentoxil); propoxyphene (Darvon; no longer available in U.S.); reserpine; salicylate pain relievers such as aspirin; and sulfonamide antibiotics such as trimethoprim/sulfamethoxazole (Bactrim, Septra).
While you are using pramlintide, you must measure your blood sugar before and after every meal and at bedtime. You also will need to see or talk to your doctor often, and frequently change your doses of pramlintide and insulin according to your doctor's directions. Tell your doctor if you think that it will be difficult for you to do these things, if you have had difficulty checking your blood sugar or using your insulin correctly in the past, or if you find it difficult to manage your treatment after you start using pramlintide.
Your doctor will decrease your dose of insulin when you start using pramlintide. Your doctor will start you on a low dose of pramlintide and will gradually increase your dose. Call your doctor right away if you have nausea during this time; your dose may need to be changed or you may have to stop using pramlintide. Your doctor will probably change your dose of insulin once you are using a dose of pramlintide that is right for you. Follow all of these directions carefully and ask your doctor or pharmacist right away if you are not sure how much insulin or pramlintide you should use.
The risk of hypoglycemia may be greater in certain situations. Call your doctor if you plan to be more active than usual. If you have any of the following conditions you should not use pramlintide and should call your doctor to find out what to do:
- you plan to skip a meal.
- you plan to eat a meal with less than 250 calories or 30 grams of carbohydrates.
- you cannot eat because you are sick.
- you cannot eat because you are scheduled for surgery or a medical test.
- your blood sugar is very low before a meal.
Alcohol may cause a decrease in blood sugar. Ask your doctor about the safe use of alcoholic beverages while you are using pramlintide.
Call your doctor right away if your blood sugar is lower than normal or if you have any of the following symptoms of low blood sugar: hunger, headache, sweating, shaking of a part of your body that you cannot control, irritability, difficulty concentrating, loss of consciousness, coma, or a seizure. Be sure that you always have a fast acting source of sugar such as hard candy, juice, glucose tablets, or glucagon available to treat hypoglycemia.
Your doctor or pharmacist will give you the manufacturer's patient information sheet (Medication Guide) when you begin treatment with pramlintide and each time you refill your prescription. Read the information carefully and ask your doctor or pharmacist if you have any questions. You can also obtain the Medication Guide from the FDA website: http://www.fda.gov.
