1. What is Lantus and what is it used for

Lantus contains insulin glargine. This is a modified insulin, very similar to human insulin.

Lantus is used to treat diabetes mellitus in adult, adolescent, and child patients from 2 years of age. Diabetes mellitus is a disease in which your body does not produce enough insulin to control the level of sugar in the blood. Insulin glargine has a long-lasting and constant blood sugar-lowering effect.

2. What you need to know before you use Lantus

Do not useLantus

If you are allergic to insulin glargine or any of the other ingredients of this medicine (listed in section 6).

Warnings and precautions

Talk to your doctor, pharmacist, or nurse before starting Lantus.

Follow strictly the instructions for dosage, monitoring (blood and urine tests), diet, and physical activity (physical work and exercise) as agreed with your doctor.

If your blood sugar is too low (hypoglycemia), follow the guidelines for hypoglycemia (see the box at the end of this leaflet).

Changes in the skin at the injection site

The injection site should be rotated to avoid changes in the skin, such as lumps under the skin. Insulin may not work well if injected into a thickened area of skin (see How to use Lantus). Contact your doctor if you are currently injecting into a thickened area of skin before starting to inject into a different area. Your doctor may advise you to check your blood sugar levels more closely and adjust your insulin dose or the dose of your other diabetes medicines.

Travel

Before traveling, consult your doctor. You may need to discuss:

• the availability of your insulin in the country you are visiting,
• insulin, syringes, etc. supplies,
• proper storage of insulin during travel,
• meal and insulin administration schedules during travel,
• possible effects of traveling across time zones,
• new health risks in the countries you will be visiting,
• what to do in emergency situations when you are unwell or become ill.

Illnesses and injuries

Your diabetes management may require special care in the following situations (e.g., adjusting your insulin dose, blood and urine tests):

• If you are ill or have a major injury, your blood sugar level may increase (hyperglycemia).
• If you do not eat enough, your blood sugar level may drop too low (hypoglycemia).

In most cases, you will need a doctor. Make sure to consult a doctor immediately.

If you have type 1 diabetes (insulin-dependent diabetes mellitus), do not stop taking your insulin and continue to take enough carbohydrates. Always inform the people taking care of you of your need for insulin.

Treatment with insulin can cause your body to produce antibodies to insulin (substances that act against insulin). However, only in very rare cases will you need to change your insulin dose.

Some patients with long-standing type 2 diabetes mellitus and pre-existing heart disease or stroke who were treated with pioglitazone (an oral antidiabetic medicine used to treat type 2 diabetes mellitus) and insulin developed heart failure. Inform your doctor as soon as possible if you experience signs of heart failure such as unusual shortness of breath or rapid weight gain or localized swelling (edema).

Children

There is no experience with the use of Lantus in children under 2 years of age.

Using Lantus with other medicines

Some medicines can cause changes in your blood sugar levels (increase, decrease, or both, depending on the situation). In each case, it may be necessary to adjust your insulin dose to avoid too low or too high blood sugar levels. Be careful when starting to take another medicine and also when stopping taking one.

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines. Ask your doctor before taking a medicine if it can affect your blood sugar level and what measures you should take.

Among the medicines that can cause a drop in your blood sugar level (hypoglycemia) are:

• all other medicines for treating diabetes,

• angiotensin-converting enzyme (ACE) inhibitors (used to treat certain heart diseases or high blood pressure),

• disopyramide (used to treat certain heart diseases),
• fluoxetine (used to treat depression),
• fibrates (used to reduce high lipid levels in the blood),
• monoamine oxidase inhibitors (MAOIs) (used to treat depression),

• pentoxifylline, propoxyphene, salicylates (such as acetylsalicylic acid, used to relieve pain and reduce fever),

• sulfonamide antibiotics.

Among the medicines that can cause an increase in your blood sugar level (hyperglycemia) are:

• corticosteroids (such as "cortisone", used to treat inflammation),
• danazol (a medicine that affects ovulation),
• diazoxide (used to treat high blood pressure),
• diuretics (used to treat high blood pressure or excess fluid retention),
• glucagon (a pancreatic hormone used to treat severe hypoglycemia),
• isoniazid (used to treat tuberculosis),
• estrogens and progestogens (such as in the birth control pill used for contraception),
• phenothiazine derivatives (used to treat psychiatric diseases),
• somatotropin (growth hormone),
• sympathomimetic medicines (such as epinephrine [adrenaline], salbutamol, terbutaline for treating asthma),
• thyroid hormones (used to treat underactive thyroid gland),
• atypical antipsychotic medicines (such as clozapine, olanzapine),
• protease inhibitors (used to treat HIV).

Your blood sugar level may rise or fall if you take:

• beta-blockers (used to treat high blood pressure),
• clonidine (used to treat high blood pressure),
• lithium salts (used to treat psychiatric diseases).

Pentamidine (used to treat some parasitic infections) can cause hypoglycemia, which can sometimes be followed by hyperglycemia.

Beta-blockers, like other sympatholytic medicines (such as clonidine, guanethidine, and reserpine), can mask or completely suppress the first warning signs of hypoglycemia that could help you recognize it.

If you are not sure whether you are taking any of these medicines, ask your doctor or pharmacist.

Using Lantus with alcohol

Your blood sugar levels may rise or fall if you drink alcohol.

Pregnancy and breastfeeding

Ask your doctor or pharmacist for advice before taking any medicine.

Tell your doctor if you are planning to become pregnant or if you are already pregnant. Your insulin dose may need to be changed during pregnancy and after delivery. Close monitoring of your diabetes and prevention of hypoglycemia are important for your baby's health.

If you are breastfeeding, consult your doctor, as you may need to adjust your insulin dose and diet.

Driving and using machines

Your ability to concentrate or react may be reduced if:

• you have hypoglycemia (low blood sugar levels),
• you have hyperglycemia (high blood sugar levels),
• you have vision problems.

Be aware of this possible problem, considering all situations that can put you or others at risk (such as driving a vehicle or using machines). You should ask your doctor for advice on driving if:

• you have frequent episodes of hypoglycemia,
• the first warning signs of hypoglycemia have decreased or disappeared.

Important information about some of the ingredients of Lantus

This medicine contains less than 1 mmol (23 mg) of sodium per dose, i.e., it is essentially "sodium-free".

3. How to use Lantus

Follow the instructions for administration of this medicine exactly as told by your doctor. If you are not sure, consult your doctor or pharmacist again.

Although Lantus contains the same active substance as Toujeo (insulin glargine 300 units/ml), these medicines are not interchangeable. Switching from one insulin treatment to another requires medical prescription, supervision, and blood glucose monitoring. For more information, consult your doctor.

Dose

Based on your lifestyle and the results of your blood sugar (glucose) tests and previous insulin treatment, your doctor will:

• determine the dose of Lantus you need each day and at what time,
• tell you when to check your blood sugar level and if you need to perform urine tests,
• tell you when you may need to inject a higher or lower dose of Lantus.

Lantus is a long-acting insulin. Your doctor may advise you to use it in combination with a short-acting insulin or with tablets to treat high blood sugar levels.

Many factors can influence your blood sugar level. You should know these factors so that you can react correctly to changes in your blood sugar level and avoid it becoming too high or too low. For more information, see the box at the end of the leaflet.

Use in children and adolescents

Lantus can be used in adolescents and children from 2 years of age. Use this medicine exactly as your doctor has told you.

Administration frequency

You need one injection of Lantus every day, always at the same time.

Method of administration

Lantus is injected under the skin. DO NOT inject Lantus into a vein, as this will change its action and may cause hypoglycemia.

Your doctor will show you which area of the skin to inject Lantus into. With each injection, change the injection site within the area of skin you are using.

Handling the vials

Inspect the vial before use. It should only be used if the solution is clear, colorless, and aqueous, and does not contain visible particles. Do not shake or mix before use. Make sure the insulin is not contaminated with alcohol or other disinfectants or substances. Do not mix Lantus with any other insulin or medicine. Do not dilute it. Mixing or diluting may change the action of Lantus.

Always use a new vial if you notice that your blood sugar control is worsening unexpectedly. This is because the insulin may have lost some of its effectiveness. If you think you may have a problem with Lantus, have it checked by your doctor or pharmacist.

Insulin confusion

Always check the label of the insulin before each injection to avoid confusion between Lantus and other insulins.

If you use more Lantus than you should

• If you have injected too much Lantus, your blood sugar level may become too low (hypoglycemia).

Check your blood sugar level frequently. In general, to prevent hypoglycemia, you should eat more and monitor your blood sugar level. For more information on treating hypoglycemia, see the box at the end of the leaflet.

If you forget to use Lantus

• If you have missed a dose of Lantus or if you have not injected enough insulin, your blood sugar level may rise too high (hyperglycemia). Check your blood sugar level frequently.

For more information on treating hyperglycemia, see the box at the end of the leaflet.

• Do not take a double dose to make up for forgotten doses.

If you stop using Lantus

This could lead to severe hyperglycemia (very high blood sugar levels) and ketoacidosis (increased acid in the blood because the body is breaking down fat instead of sugar). Do not stop your treatment with Lantus without consulting your doctor, who will tell you what to do.

If you have any further questions on the use of this medicine, ask your doctor, pharmacist, or nurse.

4. Possible side effects

Like all medicines, Lantus can cause side effects, although not everybody gets them.

If you notice signs of low blood sugar (hypoglycemia),act immediately to increase your blood sugar level (see the box at the end of this leaflet). Hypoglycemia (low blood sugar) can be very serious and is very common during insulin treatment (it can affect more than 1 in 10 people). Low blood sugar means that there is not enough sugar in the blood. If your blood sugar level drops too low, you may lose consciousness (pass out). Severe hypoglycemia can cause brain damage and can be life-threatening. For more information, see the box at the end of this leaflet.

Severe allergic reactions(rare, may affect up to 1 in 1,000 people) – the signs may include widespread skin reactions (rash and itching all over the body), severe swelling of the skin or mucous membranes (angioedema), difficulty breathing, low blood pressure with a fast heartbeat and sweating. Severe allergic reactions to insulins can be life-threatening. Tell your doctor immediatelyif you notice the signs of severe allergic reactions.

• Changes in the skin at the injection site:

If you inject insulin too frequently in the same spot, the fatty tissue can shrink (lipoatrophy) (may affect up to 1 in 100 people) or thicken (lipohipertrophy) (may affect up to 1 in 10 people). Lumps under the skin can also occur due to the accumulation of a protein called amyloid (cutaneous amyloidosis; the frequency is not known). Insulin may not work well if injected into a thickened area of skin (see How to use Lantus). Change the injection site to help avoid these skin changes.

Common side effects(may affect up to 1 in 10 people)

• Skin reactions and allergic reactions at the injection site

The signs may include redness, intense pain when injecting, itching, hives, swelling, or inflammation. These reactions can spread around the injection site. Most minor reactions to insulin disappear within a few days or weeks.

Uncommon side effects(may affect up to 1 in 1,000 people)

• Eye reactions

A significant change (improvement or worsening) in your blood sugar control can temporarily affect your vision. If you have proliferative retinopathy (a disease of the eyes related to diabetes), severe hypoglycemic attacks can cause temporary loss of vision.

• General disorders

In rare cases, insulin treatment can also cause temporary water retention in the body, with swelling of the ankles and feet.

Rare side effects(may affect up to 1 in 10,000 people)

In very rare cases, disgeusia (taste disorders) and myalgia (muscle pain) can occur.

Use in children and adolescents

Generally, side effects in children and adolescents under 18 years of age are similar to those in adults.

Reactions at the injection site (pain at the injection site, reaction at the injection site) and skin reactions (rash, hives) have been reported more frequently in children and adolescents under 18 years of age than in adults.

There is no experience in children under 2 years of age.

Reporting of side effects

If you experience any side effects, talk to your doctor or pharmacist. This includes any possible side effects not listed in this leaflet. You can also report side effects directly through the national reporting system listed in Appendix V. By reporting side effects, you can help provide more information on the safety of this medicine.

HYPERGLYCEMIA AND HYPOGLYCEMIA

Always carry something with sugar (at least 20 grams) with you.

Always carry some information that indicates you are diabetic.

HYPERGLYCEMIA (high blood sugar levels)

If you have very high blood sugar levels (hyperglycemia), you may not have injected enough insulin.

Why do you get hyperglycemia?

Some examples are:

• you have not injected your insulin or have not injected enough, or if its effect has decreased, for example, due to incorrect storage,
• you are doing less exercise than usual, are under stress (emotional distress, nervousness), or are suffering from an injury, surgery, infection, or fever,
• you are taking or have taken certain medications (see section 2, "Use of Lantus with other medications").

Warning symptoms of hyperglycemia

Thirst, increased need to urinate, fatigue, dry skin, redness of the face, loss of appetite, low blood pressure, rapid heartbeat, and the presence of glucose and ketone bodies in the urine. Stomach pain, deep and rapid breathing, drowsiness, or even loss of consciousness may be signs of a serious condition (ketoacidosis) due to lack of insulin.

What should you do if you suffer from hyperglycemia?

You should analyze your blood sugar level and your ketone level in the urine as soon as any of the above symptoms occur.Severe hyperglycemia or ketoacidosis should always be treated by a doctor, usually in a hospital.

HYPOGLYCEMIA (low blood sugar levels)

If your blood sugar level drops too low, you may lose consciousness. Severe hypoglycemia can cause a heart attack or brain damage and can be life-threatening. You should normally be able to recognize when your blood sugar level is dropping too low to take the necessary measures.

Why do you get hypoglycemia?

Some examples are:

• you inject too much insulin,
• you miss meals or delay them,
• you do not eat enough, or eat foods that contain less carbohydrates than usual (sugar and substances similar to sugar are called carbohydrates; however, artificial sweeteners are NOT carbohydrates),
• you lose carbohydrates due to vomiting or diarrhea,
• you drink alcohol, especially if you are not eating much,
• you are doing more exercise than usual or a different type of physical activity,
• you are recovering from an injury, surgery, or other types of stress,
• you are recovering from an illness or fever,
• you are taking or have stopped taking certain medications (see section 2, "Use of Lantus with other medications").

It is also more likely to get hypoglycemia if:

• you have just started insulin treatment or changed to another insulin preparation (when you switch from your previous basal insulin to Lantus, if hypoglycemia occurs, it is more likely to happen in the morning than at night),
• your blood sugar levels are almost normal or unstable,
• you change the injection site (e.g., from the thigh to the upper arm),
• you have a serious kidney or liver disease, or other conditions such as hypothyroidism.

Warning symptoms of hypoglycemia

• In your body

Examples that indicate your blood sugar level is dropping too low or too quickly: sweating, moist and sticky skin, anxiety, rapid heartbeat, high blood pressure, palpitations, and irregular heartbeat. These symptoms often occur before symptoms of low blood sugar in the brain appear.

• In your brain

Examples that indicate low blood sugar in the brain: headaches, intense hunger, nausea, vomiting, fatigue, drowsiness, sleep disturbances, restlessness, aggressive behavior, concentration problems, altered reactions, depression, confusion, speech disturbances (sometimes, complete loss of speech), visual disturbances, tremors, paralysis, tingling sensations (paresthesias), numbness and tingling sensations around the mouth, dizziness, loss of self-control, feeling of helplessness, convulsions, loss of consciousness.

The first warning symptoms of hypoglycemia ("warning symptoms") may change, weaken, or be absent if

• you are elderly,
• you have had diabetes for a long time,
• you have a certain type of nerve disease (autonomic diabetic neuropathy),
• you have recently had a hypoglycemic episode (e.g., the day before) or if it develops gradually,
• you have almost normal or improved blood sugar levels,
• you have recently changed from an animal insulin to a human insulin like Lantus,
• you are taking or have taken certain medications (see section 2, "Use of Lantus with other medications").

In this case, you may experience severe hypoglycemia (and even lose consciousness) before you realize the problem. Always be familiar with your warning symptoms. If necessary, more frequent blood sugar analysis can help identify mild hypoglycemic episodes that would otherwise go unnoticed. If you are not sure you can recognize your warning symptoms, avoid situations (such as driving a car) that could put you or others at risk due to hypoglycemia.

What should you do if you suffer from hypoglycemia?

1. Do not inject insulin. Immediately ingest 10 to 20 grams of sugar, such as glucose, sugar cubes, or a sugary drink. Note: Artificial sweeteners and sugar-free products do not help treat hypoglycemia.
2. Afterwards, eat something that increases your blood sugar level in the long term (such as bread or pasta). Your doctor or nurse should have discussed this with you beforehand.

Recovery from hypoglycemia may be delayed because Lantus has a prolonged action.

1. If hypoglycemia recurs, take another 10 to 20 grams of sugar.
2. Consult a doctor immediately if you are unable to control hypoglycemia or if it recurs.

Tell your family, friends, and people close to you:

If you are unable to swallow or lose consciousness, you will need an injection of glucose or glucagon (a medication that increases blood sugar levels). These injections are justified even if you are not sure you have hypoglycemia.

It is recommended to analyze your blood sugar level immediately after ingesting glucose to confirm that you actually have hypoglycemia.
