What is Lantus Solostar Pen?

See also: Basaglar

Lantus Solostar Pen is a long-acting insulin that starts to work several hours after injection and keeps working evenly for 24 hours.

Lantus Solostar Pen is used to improve blood sugar control in adults and children with diabetes mellitus. This medicine is used to treat type 1 or type 2 diabetes in adults, and type 1 diabetes children who are at least 6 years old.

Some brands of Lantus Solostar Pen are for use only in adults. Carefully follow all instructions for the brand of insulin glargine you are using.

Lantus Solostar Pen may also be used for purposes not listed in this medication guide.

Important Information

Never share an injection pen or syringe with another person, even if the needle has been changed.

Before taking this medicine

You should not use Lantus Solostar Pen if you are allergic to insulin, or if you are having an episode of hypoglycemia (low blood sugar) or diabetic ketoacidosis.

Lantus Solostar Pen is not approved for use by anyone younger than 6 years old, and some brands are for use only in adults. Do not use this medicine to treat type 2 diabetes in a child of any age.

Tell your doctor if you have ever had:

  • liver or kidney disease; or

  • heart failure or other heart problems.

Tell your doctor if you also take pioglitazone or rosiglitazone (sometimes contained in combinations with glimepiride or metformin). Taking certain oral diabetes medicines while you are using insulin may increase your risk of serious heart problems.

Follow your doctor's instructions about using insulin if you are pregnant or breast-feeding a baby. Blood sugar control is very important during pregnancy, and your dose needs may be different during each trimester of pregnancy. Your dose needs may also be different while you are breast-feeding.

How should I use Lantus Solostar Pen?

Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.

Lantus Solostar Pen is injected under the skin. A healthcare provider may teach you how to properly use the medication by yourself.

Lantus Solostar Pen must not be given with an insulin pump, or mixed with other insulins. Do not inject this medicine into a vein or a muscle.

Read and carefully follow any Instructions for Use provided with your medicine. Do not use Lantus Solostar Pen if you don't understand all instructions for proper use. Ask your doctor or pharmacist if you have questions.

The Toujeo brand of insulin glargine contains 3 times as much insulin per milliliter (mL) as the Lantus or Basaglar brands. There are 300 units of insulin in 1 mL of Toujeo, and 100 units in 1 mL of Lantus or Basaglar.

If there are any changes in the brand, strength, or type of insulin you use, your dosage needs may change.

If you use an injection pen, use only the injection pen that comes with Lantus Solostar Pen. Attach a new needle before each use. Do not transfer the insulin from the pen into a syringe.

Never share an injection pen or syringe with another person, even if the needle has been changed. Sharing these devices can allow infections or disease to pass from one person to another.

Low blood sugar (hypoglycemia) can happen to everyone who has diabetes. Symptoms include headache, hunger, sweating, irritability, dizziness, nausea, and feeling shaky. To quickly treat low blood sugar, always keep a fast-acting source of sugar with you such as fruit juice, hard candy, crackers, raisins, or non-diet soda.

Your doctor can prescribe a glucagon emergency injection kit to use in case you have severe hypoglycemia and cannot eat or drink. Be sure your family and close friends know how to give you this injection in an emergency.

Also watch for signs of high blood sugar (hyperglycemia) such as increased thirst or urination, blurred vision, headache, and tiredness.

Blood sugar levels can be affected by stress, illness, surgery, exercise, alcohol use, or skipping meals. Ask your doctor before changing your dose or medication schedule.

Keep this medicine in its original container protected from heat and light. Do not draw insulin from a vial into a syringe until you are ready to give an injection. Do not freeze insulin or store it near the cooling element in a refrigerator. Throw away any insulin that has been frozen.

What happens if I miss a dose?

Call your doctor for instructions if you miss a dose of Lantus Solostar Pen. You should not use more than one dose in a 24-hour period unless your doctor tells you to.

Get your prescription refilled before you run out of medicine completely.

What happens if I overdose?

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. Insulin overdose can cause life-threatening hypoglycemia. Symptoms include drowsiness, confusion, blurred vision, numbness or tingling in your mouth, trouble speaking, muscle weakness, clumsy or jerky movements, seizure (convulsions), or loss of consciousness.

What should I avoid while using Lantus Solostar Pen?

Avoid driving or hazardous activity until you know how Lantus Solostar Pen will affect you. Your reactions could be impaired.

Avoid medication errors by always checking the medicine label before injecting your insulin.

Avoid drinking alcohol. It can cause low blood sugar and may interfere with your diabetes treatment.

Lantus Solostar Pen side effects

Get emergency medical help if you have signs of insulin allergy: redness or swelling where an injection was given, itchy skin rash over the entire body, trouble breathing, fast heartbeats, feeling like you might pass out, or swelling in your tongue or throat.

Call your doctor at once if you have:

  • rapid weight gain, swelling in your feet or ankles;

  • shortness of breath; or

  • low potassium--leg cramps, constipation, irregular heartbeats, fluttering in your chest, increased thirst or urination, numbness or tingling, muscle weakness or limp feeling.

Common side effects may include:

  • low blood sugar;

  • itching, mild skin rash; or

  • thickening or hollowing of the skin where you injected the medicine.

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

What other drugs will affect Lantus Solostar Pen?

Many other medicines can affect your blood sugar, and some medicines can increase or decrease the effects of insulin. Some drugs can also cause you to have fewer symptoms of hypoglycemia, making it harder to tell when your blood sugar is low. Tell each of your health care providers about all medicines you use now and any medicine you start or stop using. This includes prescription and over-the-counter medicines, vitamins, and herbal products.
