Most people with diabetes want stable blood sugar without constant shots. Lantus is a long-acting (basal) insulin many doctors prescribe to cover insulin needs for 24 hours. It doesn’t replace mealtime insulin — it gives steady background control so you get fewer highs and lows.
Lantus is insulin glargine, a slow-release insulin you inject once a day. It starts working in a few hours and lasts about 24 hours with a flat profile — meaning no big peaks. People with type 1 diabetes often combine it with fast-acting insulin at meals. People with type 2 diabetes may use it when oral meds aren’t enough. Your clinician will pick the right dose based on your blood sugar logs and health goals.
Not everyone is a candidate: if you have low blood sugar unawareness or allergy to insulin glargine, talk to your provider. Also mention pregnancy or planning pregnancy — insulin needs change during these times.
Follow your prescription exactly. Typical start doses vary, but small daily adjustments (2–4 units) are common until your fasting glucose hits target. Check fasting blood glucose most mornings and record results — that’s how dose decisions are made.
Injection technique matters. Use the pen device or syringe as instructed: rotate injection sites (abdomen, thigh, buttock, upper arm) to avoid lumps under the skin. Inject at a 90-degree angle, pinch skin only if you’re thin, and don't rub the spot afterward. Dispose of needles in a proper sharps container.
Timing is flexible but pick the same time each day — many choose bedtime or morning. If you miss a dose and it’s within a few hours, take it. If it’s close to your next dose, skip the missed one and resume your schedule; don’t double up. When switching between insulin types or brands, talk to your healthcare team — doses can differ.
Store unopened Lantus in the fridge. Once in use, the pen or vial can stay at room temperature for the time specified on the label (usually 28 days), which helps when traveling. Keep it away from direct heat and sunlight.
Watch for common side effects: low blood sugar (sweating, shaking, dizziness), weight gain, injection-site reactions. Severe allergic reactions are rare but need immediate care. If you regularly get low sugars, review your meals, activity, and other medicines — things like sulfonylureas or alcohol can increase risk.
Finally, keep a relationship with your prescriber and diabetes educator. Blood sugar targets change with age, activity, illness, and other meds. Bring a glucose log to appointments and ask clear questions about sick-day plans, travel, and how to handle low sugars. That makes Lantus work better and fits it into your life with less worry.
