Lantus  Information
Lantus is indicated for the treatment of adults, adolescents and children of 6 years or above with diabetes mellitus, where treatment with insulin is required. Lantus contains insulin glargine, an insulin analogue with a prolonged duration of action. It should be administered once daily at any time, but at the same time each day.

The dosage and timing of dose of Lantus should be individually adjusted. In patients with type 2 diabetes mellitus, Lantus can also be given together with orally active antidiabetic medicinal products.

Children- In children efficacy and safety of Lantus have only been demonstrated when given in the evening. Due to limited experience the efficacy and safety of Lantus have not been demonstrated in children below the age of 6 years.

Transition from other insulins to Lantus- When changing from a treatment regimen with an intermediate or long-acting insulin to a regimen with Lantus, a change of the dose of the basal insulin may be required and the concomitant antidiabetic treatment may need to be adjusted (dose and timing of additional regular insulins or fast-acting insulin analogues or the dose of oral antidiabetic agents).

To reduce the risk of nocturnal and early morning hypoglycaemia, patients who are changing their basal insulin regimen from a twice daily NPH insulin to a once daily regimen with Lantus should reduce their daily dose of basal insulin by 20-30% during the first weeks of treatment.

During the first weeks the reduction should, at least partially, be compensated by an increase in mealtime insulin, after this period the regimen should be adjusted individually.
As with other insulin analogues, patients with high insulin doses because of antibodies to human insulin may experience an improved insulin response with Lantus.
Close metabolic monitoring is recommended during the transition and in the initial weeks thereafter.
With improved metabolic control and resulting increase in insulin sensitivity a further adjustment in dosage regimen may become necessary. Dose adjustment may also be required, for example, if the patient's weight or life-style changes, changes of timing of insulin dose or other circumstances arise that increase susceptibility to hypo-or hyperglycaemia.

Lantus is administered subcutaneously. “Prescription required for orders placed from the USA”.
Lantus should not be administered intravenously. The prolonged duration of action of Lantus is dependent on its injection into subcutaneous tissue. Intravenous administration of the usual subcutaneous dose could result in severe hypoglycaemia.
There are no clinically relevant differences in serum insulin or glucose levels after abdominal, deltoid or thigh administration of Lantus. Injection sites must be rotated within a given injection area from one injection to the next.
Lantus must not be mixed with any other insulin or diluted. Mixing or diluting can change its time/action profile and mixing can cause precipitation.

A number of substances affect glucose metabolism and may require dose adjustment of insulin glargine. Substances that may enhance the blood-glucose-lowering effect and increase susceptibility to hypoglycaemia include oral antidiabetic agents, ACE inhibitors, disopyramide, fibrates, fluoxetine, MAO inhibitors, pentoxifylline, propoxyphene, salicylates and sulphonamide antibiotics.
Substances that may reduce the blood-glucose-lowering effect include corticosteroids, danazol, diazoxide, diuretics, glucagon, isoniazid, oestrogens and progestogens, phenothiazine derivatives, somatropin, sympathomimetic agents (e.g. epinephrine [adrenaline], salbutamol, terbutaline), thyroid hormones, atypical antipsychotic medicinal products (e.g. clozapine and olanzapine) and protease inhibitors.
Beta-blockers, clonidine, lithium salts or alcohol may either potentiate or weaken the blood-glucose-lowering effect of insulin. Pentamidine may cause hypoglycaemia, which may sometimes be followed by hyperglycaemia.
In addition, under the influence of sympatholytic medicinal products such as beta-blockers, clonidine, guanethidine and reserpine, the signs of adrenergic counter-regulation may be reduced or absent.

Lantus  Side Effects
Hypoglycaemia- Hypoglycaemia, in general the most frequent undesirable effect of insulin therapy, may occur if the insulin dose is too high in relation to the insulin requirement. Severe hypoglycaemic attacks, especially if recurrent, may lead to neurological damage. Prolonged or severe hypoglycaemic episodes may be life-threatening. In many patients, the signs and symptoms of neuroglycopenia are preceded by signs of adrenergic counter-regulation. Generally, the greater and more rapid the decline in blood glucose, the more marked is the phenomenon of counter-regulation and its symptoms. Eyes- A marked change in glycaemic control may cause temporary visual impairment, due to temporary alteration in the turgidity and refractive index of the lens. Long-term improved glycaemic control decreases the risk of progression of diabetic retinopathy. However, intensification of insulin therapy with abrupt improvement in glycaemic control may be associated with temporary worsening of diabetic retinopathy. In patients with proliferative retinopathy, particularly if not treated with photocoagulation, severe hypoglycaemic episodes may result in transient amaurosis. Lipodystrophy- As with any insulin therapy, lipodystrophy may occur at the injection site and delay local insulin absorption. In clinical studies, in regimens which included Lantus, lipohypertrophy was observed in 1 to 2% of patients, whereas lipoatrophy was uncommon. Continuous rotation of the injection site within the given injection area may help to reduce or prevent these reactions. Injection site and allergic reactions- In clinical studies, in regimens which included Lantus, reactions at the injection site were observed in 3 to 4% of patients. Such reactions include redness, pain, itching, hives, swelling, or inflammation. Most minor reactions to insulins at the injection site usually resolve in a few days to a few weeks. Immediate-type allergic reactions to insulin are rare. Such reactions to insulin (including insulin glargine) or the excipients may, for example, be associated with generalised skin reactions, angio-oedema, bronchospasm, hypotension and shock, and may be life-threatening. Other reactions include: Insulin administration may cause insulin antibodies to form. In clinical studies, antibodies that cross-react with human insulin and insulin glargine were observed with the same frequency in both NPH and insulin glargine treatment groups. In rare cases, the presence of such insulin antibodies may necessitate adjustment of the insulin dose in order to correct a tendency to hyper- or hypoglycaemia. Rarely, insulin may cause sodium retention and oedema, particularly if previously poor metabolic control is improved by intensified insulin therapy.
