Overview
What is this medicine?
How to Use This Medicine
To use this medication correctly, follow your doctor's instructions and read all the information provided. This medication is administered via injection into the fatty tissue under the skin, typically in the thigh, abdominal area, or upper arm. If you will be self-administering the injection, your doctor or nurse will provide guidance on the proper technique.
Before use, wash your hands thoroughly. If you take this medication once daily, you can administer it at any time of day, but be sure to take it at the same time every day. Rotate the injection site with each use to avoid damaging the skin.
Important Administration Guidelines
Avoid injecting into skin that is thickened, has pits or lumps, or is irritated, tender, bruised, red, scaly, hard, scarred, or has stretch marks.
Do not use the medication if the solution appears cloudy, is leaking, or contains particles, or if the solution has changed color.
Remove all pen needle covers before injecting a dose. If you are unsure about the type of pen needle you have or how to use it, consult your doctor.
Do not transfer the medication from the pen to a syringe.
You may hear a clicking sound when preparing the dose, but do not rely on the clicks to determine the correct dose.
After each injection, remove the needle and do not store the device with the needle attached.
Dispose of used needles in a designated sharps disposal container. Do not reuse needles or other items, and follow local regulations for disposing of the container when it is full.
Additional Important Information
Do not mix this insulin with other types of insulin or liquids in the same syringe.
Follow the diet and exercise plan recommended by your doctor.
This medication is not suitable for use in an insulin pump. If you have questions, consult your doctor.
Storage and Disposal
Store unopened pens in the refrigerator, but do not freeze. If the medication has been frozen, do not use it.
If an unopened container has been stored at room temperature, consult your doctor or pharmacist to determine how long it can be safely used.
Store opened pens at room temperature, but do not refrigerate. Discard any unused medication after 56 days.
Missed Dose Instructions
If you miss a dose, take it as soon as you remember.
If it is close to the time for your next injection, skip the missed dose and resume your regular schedule.
Do not take two doses at the same time or extra doses. If you are unsure about what to do if you miss a dose, consult your doctor.
Lifestyle & Tips
- Administer insulin glargine U-300 once daily at the same time each day.
- Always check the insulin label carefully before each injection to avoid medication errors (e.g., confusing U-100 with U-300, or other insulins).
- Rotate injection sites within the same region (e.g., abdomen, thigh, upper arm) to reduce the risk of lipodystrophy (skin thickening or pitting). Do not inject into areas of lipodystrophy or scarred skin.
- Never share insulin pens or needles with other people, even if the needle is changed. This can transmit infections.
- Do not mix insulin glargine U-300 with any other insulin or solution.
- Follow a healthy diet plan and engage in regular physical activity as advised by your healthcare provider.
- Monitor your blood glucose levels regularly as instructed by your doctor.
- Always carry a source of fast-acting sugar (e.g., glucose tablets, fruit juice, hard candy) to treat mild to moderate hypoglycemia.
- Inform your healthcare provider about all medications, supplements, and herbal products you are taking, as they can affect blood sugar levels.

* Pregnancy and Breastfeeding: If you are pregnant, plan to become pregnant, or are breastfeeding, discuss the benefits and risks of this medication with your doctor.
Overdose Information
Overdose Symptoms:
- Severe hypoglycemia (dangerously low blood sugar)
- Hypokalemia (low potassium levels)
What to Do:
Mild hypoglycemia can be treated by oral glucose. Severe hypoglycemia requires immediate administration of glucagon (intramuscular or subcutaneous) or intravenous glucose. Hypokalemia should be corrected. Call 911 or 1-800-222-1222 (Poison Control Center) immediately.
Drug Interactions
Major Interactions
- Beta-blockers (may mask symptoms of hypoglycemia, prolong recovery from hypoglycemia)
- Thiazolidinediones (TZDs) - e.g., pioglitazone, rosiglitazone (increased risk of fluid retention and heart failure when used with insulin)
- Corticosteroids (may increase blood glucose, requiring higher insulin doses)
- Diuretics (especially thiazide and loop diuretics, may cause hyperglycemia)
- Sympathomimetics (e.g., albuterol, epinephrine, may increase blood glucose)
- Atypical antipsychotics (e.g., olanzapine, clozapine, may cause hyperglycemia)
Moderate Interactions
- ACE inhibitors (may enhance insulin's glucose-lowering effect)
- Angiotensin Receptor Blockers (ARBs) (may enhance insulin's glucose-lowering effect)
- Salicylates (e.g., aspirin, may enhance insulin's glucose-lowering effect at high doses)
- Sulfonamide antibiotics (may enhance insulin's glucose-lowering effect)
- Monoamine Oxidase Inhibitors (MAOIs) (may enhance insulin's glucose-lowering effect)
- Alcohol (can potentiate or diminish insulin's effect, increasing risk of hypoglycemia or hyperglycemia)
Minor Interactions
- Not specifically categorized as minor for insulin, as most interactions affect glucose levels significantly.
Monitoring
Baseline Monitoring
Rationale: To establish baseline glycemic control and set treatment goals.
Timing: Prior to initiation of therapy.
Rationale: To establish baseline glucose levels and guide initial dosing.
Timing: Prior to initiation of therapy.
Rationale: To assess kidney function, as insulin requirements may decrease in renal impairment.
Timing: Prior to initiation, especially in elderly or those with risk factors.
Rationale: To assess liver function, as insulin requirements may decrease in hepatic impairment.
Timing: Prior to initiation, especially in those with risk factors.
Routine Monitoring
Frequency: Daily, multiple times a day (e.g., fasting, pre-meal, bedtime) as directed by healthcare provider.
Target: Individualized, typically 80-130 mg/dL (fasting/pre-meal) for most non-pregnant adults.
Action Threshold: Below target (hypoglycemia) or above target (hyperglycemia) requiring dose adjustment or intervention.
Frequency: Every 3-6 months (or more frequently if glycemic control is not stable or treatment is changed).
Target: Individualized, typically <7% for most non-pregnant adults.
Action Threshold: Above target, indicating need for dose adjustment or treatment modification.
Frequency: Continuously, patient education on recognition.
Target: N/A
Action Threshold: Any occurrence of symptoms (e.g., sweating, tremor, confusion, dizziness) requires immediate action.
Frequency: Regularly (e.g., daily or weekly)
Target: No redness, swelling, lumps, or lipodystrophy.
Action Threshold: Presence of abnormalities requires rotation of injection sites or medical evaluation.
Symptom Monitoring
- Symptoms of hypoglycemia: sweating, dizziness, lightheadedness, tremor, palpitations, anxiety, hunger, confusion, irritability, headache, blurred vision, slurred speech, weakness, seizures, unconsciousness.
- Symptoms of hyperglycemia: increased thirst, increased urination, dry mouth, fatigue, blurred vision, nausea, vomiting, abdominal pain (especially in DKA).
- Symptoms of fluid retention/heart failure (if co-administered with TZDs): unusual weight gain, swelling in ankles/feet, shortness of breath.
Special Patient Groups
Pregnancy
Insulin glargine is generally considered safe and effective for use during pregnancy. Available data from published observational studies and postmarketing reports have not reported an association with major birth defects, miscarriage, or adverse maternal or fetal outcomes. Careful monitoring of blood glucose is essential, and insulin requirements may change throughout pregnancy.
Trimester-Specific Risks:
Lactation
Insulin glargine is compatible with breastfeeding. Insulin is a normal component of human milk and is not orally absorbed by the infant. No adverse effects on the breastfed infant are expected. Maternal insulin requirements may decrease during lactation.
Pediatric Use
Approved for children 6 years and older with Type 1 or Type 2 diabetes. Dosing must be individualized and carefully titrated based on blood glucose monitoring. Increased risk of hypoglycemia, especially in younger children who may not recognize symptoms.
Geriatric Use
No specific dose adjustment is required based on age alone. However, elderly patients may be more susceptible to the hypoglycemic effects of insulin and may have impaired renal or hepatic function, which can affect insulin requirements. Close glucose monitoring and careful dose titration are recommended.
Clinical Information
Clinical Pearls
- Insulin Glargine U-300 (Toujeo) has a more prolonged and stable glucose-lowering effect (up to 36 hours) compared to U-100 glargine (Lantus/Basaglar), which lasts up to 24 hours. This can provide more consistent basal coverage.
- Patients transitioning from U-100 glargine to U-300 glargine typically require a 10-15% higher dose of U-300 to achieve similar glycemic control due to differences in absorption characteristics.
- U-300 glargine is available in Solostar (1.5 mL) and Max Solostar (3 mL) pens. Both deliver U-300 insulin, but the Max Solostar pen delivers a higher maximum single dose (160 units vs 80 units for Solostar).
- Always instruct patients to dial the dose in units, not volume. The pen automatically converts the dose to the correct volume of U-300 insulin.
- Emphasize the importance of injecting at the same time each day to maintain consistent basal insulin levels.
- Educate patients on proper injection technique and rotation of injection sites to prevent lipohypertrophy, which can impair insulin absorption.
- Stress the importance of never sharing pens or needles due to infection risk.
Alternative Therapies
- Other classes of antidiabetic agents (e.g., Metformin, Sulfonylureas, DPP-4 inhibitors, SGLT2 inhibitors, GLP-1 receptor agonists, Thiazolidinediones, Meglitinides, Alpha-glucosidase inhibitors, Amylin analogs)
- Other insulin regimens (e.g., multiple daily injections of rapid-acting insulin with U-100 basal insulin, insulin pumps)
