Product introduction
Lantus is a long-acting insulin used to manage blood sugar levels in people living with type 1 or type 2 diabetes. It contains insulin glargine, a laboratory-made version of human insulin that has been modified to release slowly and steadily into the bloodstream. Because it works over roughly 24 hours from a single dose, it is typically used as the base or 'background' insulin alongside diet, exercise, and sometimes other diabetes medicines. It comes in a pre-filled cartridge meant for use with a compatible reusable insulin pen.
Storage: Store in a refrigerator (2 - 8°C). Do not freeze.
Uses of Lantus 100IU/ml Solution for Injection
- Type 1 diabetes mellitus
- Type 2 diabetes mellitus
- Long-term blood sugar control
Benefits of Lantus 100IU/ml Solution for Injection
By providing a steady background level of insulin, Lantus helps keep fasting and between-meal blood sugar in a more stable range, which reduces the swings that lead to both hyperglycemia and reactive lows. Better day-to-day glucose control also lowers the long-term risk of diabetes-related complications affecting the eyes, kidneys, nerves, and heart.
Side effects of Lantus 100IU/ml Solution for Injection
Most side effects do not require medical attention and go away as your body adjusts. Consult your doctor if they persist.
- Hypoglycemia (low blood sugar)
- Injection site reactions
- Swelling (edema)
- Weight gain
- Itching or rash
- Lipodystrophy (skin changes at injection site)
How to use Lantus 100IU/ml Solution for Injection
Lantus is injected under the skin (subcutaneously) once a day, ideally at the same time each day, into the thigh, upper arm, or abdomen, with the injection site rotated regularly. It should be used exactly as prescribed by the doctor, since the dose is individualized based on blood sugar readings, diet, and activity level. It must never be mixed with other insulins in the same syringe or diluted.
How Lantus 100IU/ml Solution for Injection works
Insulin glargine forms fine micro-precipitates just under the skin after injection, which dissolve gradually and release small, steady amounts of insulin into the blood over about 24 hours. This mimics the slow background insulin secretion of a healthy pancreas, helping body cells take up glucose from the blood for energy while signalling the liver to reduce its own glucose output.

Safety advice
Alcohol can mask the warning signs of low blood sugar and increase the risk of hypoglycemia, so it should be consumed carefully and never on an empty stomach.
Insulin glargine can be used in pregnancy under a doctor's supervision, as good glucose control is important for both mother and baby.
Insulin is generally considered compatible with breastfeeding, but the dose may need adjustment and should be guided by a doctor.
Driving should be avoided if blood sugar is low or fluctuating, as hypoglycemia can impair concentration and reaction time.
People with reduced kidney function may need closer monitoring and dose adjustment since insulin requirements can change.
Liver impairment can affect how the body processes glucose and insulin, so dosing should be supervised by a doctor.
Quick tips
- Inject at the same time every day to keep blood sugar control consistent
- Rotate injection sites within the same body region to prevent skin lumps
- Keep unopened cartridges refrigerated; a cartridge in use can be kept at room temperature away from heat and light for the period stated on the pack
- Always check blood glucose regularly and carry a fast-acting sugar source in case of hypoglycemia
- Never share pens or cartridges with another person, even with a new needle

Frequently asked questions
Can Lantus be mixed with other insulins?
No, Lantus should not be mixed or diluted with any other insulin or solution in the same syringe, as this can change how it works.
What should I do if I miss a dose?
If a dose is missed, check blood sugar and contact your doctor for guidance rather than doubling the next dose on your own.
Is Lantus the same as regular fast-acting insulin?
No, Lantus is a long-acting basal insulin that provides steady background coverage, unlike fast-acting insulins taken around meals.
Does Lantus need to stay refrigerated at all times?
Unopened cartridges must be refrigerated, but once a cartridge is in use it can usually be kept at room temperature for a limited period as mentioned on the pack, away from direct heat and sunlight.
Can the dose of Lantus change over time?
Yes, the dose is often adjusted by the doctor based on blood sugar trends, weight changes, illness, or changes in diet and activity.
