Lantus (insulin glargine)Diabetes

Any information on this website should be discussed with a healthcare professional and doesn’t replace a healthcare professional advice.

You may be exercising, watching what you eat and making an effort to look after yourself but if your blood sugar levels are still high because of Type 2 Diabetes you’ll need to get it sorted.

Over time having high blood sugar can affect your eyes, kidneys, nervous system, and heart. Left untreated it can cause serious problems down the track meaning you might not be able to be there for the people you love.

Your doctor may have told you other diabetes medicines are no longer enough to keep your levels under control, and that it’s time to work with you on treatment options to help manage your blood sugar.

It’s not easy to hear. But the fact is, when you have Type 2 Diabetes, your body doesn’t make enough insulin and/or your body does not properly use the insulin it makes. Over time, no matter how much you try to manage your diabetes, your body will make less insulin and that’s why your doctor may have also suggested adding insulin therapy to your diabetes treatment plan.

Ask your doctor if helping control high blood sugar with Lantus® is right for you.

About Blood Sugar Control
By now, you know that many things can impact your blood sugar levels. Simple things, like the foods you eat, your overall activity level, and even your stress levels. That’s why, above all, it’s important to stay focused on your goals – for yourself and for those you love.

There are many different ways your blood sugar levels can become too high or low. Learn how your diet, medication, and exercise can impact your levels. Learn how your blood sugar levels can change, sometimes dramatically. Learn how to help recognise when your blood sugar is too high or too low and things you can do to manage them.

Your Blood Sugar Goal. What Target Ranges are Right for You?
Most people with type 2 diabetes should have blood sugar levels within this range: 4.0 mmol/moL and 10.0 mmol/L3 when testing before meals.

What Is HbA1c?
HbA1c test measures your average blood sugar levels over the past 2 to 3 months. It provides a picture of your success managing blood sugar over a longer period of time. Ask your doctor about blood sugar and HbA1c goals that are right for you, and if your HbA1c is too high, ask about ways you can get it on track. It is recommended that your doctor measures your HbA1c level at least every three months.

Managing Blood Sugar Highs and Lows
What to do when your blood sugar levels rise too high or fall too low
Even if you’re very careful about the things you eat, how much you exercise, take your medicine as prescribed, and fill out your blood sugar log, there may be times when your blood sugar levels climb above or fall below where you and your doctor want them to be.

It’s important to recognise the signs of hyperglycaemia and hypoglycaemia, what causes them, and what you can do to treat them. However, the first thing to remember is not to panic when you have blood sugar readings that are too high or too low, take action.

Blood Sugar Levels4

What can drive them up

  • Eating too much sugary or starchy food
  • Not getting enough physical activity
  • Not taking your medication
  • Sickness
  • Emotional stress
  • Your medication needs adjusting
What can bring them down

  • Missing a meal or snack
  • Not eating enough carbohydrate
  • More physical activity than usual
  • Taking too many diabetes pills or too much insulin
  • Drinking too much alcohol

If your blood sugar level climbs too high, you may experience symptoms of hyperglycaemia, which may include: 3,4,6

  • Tiredness, loss of energy
  • Frequent urination
  • Blurred vision
  • Increased thirst
  • Dry mouth
  • Frequent infections

Hyperglycaemia can be caused by simple things, like eating too much sugary or starchy food, getting too little exercise, or an illness or stress. The only way to know for sure whether or not you have hyperglycaemia is to check your blood sugar level.

Beware – if your blood sugar has increased slowly over time you may not have any symptoms of hyperglycaemia. Your body can get used to having high blood glucose levels, and this can result in long-term complications, such as eye, kidney, and nerve damage.4

If your blood sugar level drops too low, you may experience symptoms of hypoglycaemia, which may include: 3-6

  • Feeling hungry
  • Feeling light-headed or dizzy
  • Sweaty skin
  • Blurred eyesight
  • Confused, anxious or irritable
  • Headache
  • Trembling or weak hands and knees
  • Pins and needles around the lips and tongue
  • Thumping heart

What happens if it is not treated?
If not treated quickly, the blood glucose level can continue to drop which may progress to:

  • loss of coordination
  • slurred speech
  • loss of consciousness/fitting

If you feel unwell and suspect hyperglycaemia or hypoglycaemia, check your sugar levels and consult with a healthcare professional.

Hypoglycaemia is an important risk to be aware of for people on insulin therapy, such as Lantus®.

Your Blood Sugar Log
Track your progress with a daily log
A good way to track your progress and recognise patterns that affect your blood sugar levels over time is by maintaining your daily log. A Lantus® diabetes logbook is available.

Call Freephone: 0800 526 887 (option 5) Monday to Friday between the hours of 9am and 5pm.

Aside from keeping track of your blood sugar levels, remember to write down anything that’s outside of your normal routine. If you notice unusual symptoms or an unexpected change in your numbers, please call your healthcare professional. The amount of sugary and starchy food you eat, how much you eat (you could eat alot of protein and your blood sugar would not go up), and when you eat can all affect your blood sugar levels. So can exercise and stress. All this information will help your doctor recommend how to adjust your treatment plan if it becomes necessary.

You’ll also notice that your blood sugar readings vary. That’s ok. Blood sugar levels always vary. They vary from person to person and from time to time in the same person. Speak to your doctor about what ranges are right for you.
