Toujeo Adverse Reactions

Summary of the safety profile: The following adverse reactions were observed during clinical studies conducted with Toujeo (see Pharmacology: Pharmacodynamics under Actions) and during clinical experience with insulin glargine 100 units/ml.
Hypoglycaemia, in general the most frequent adverse reaction of insulin therapy, may occur if the insulin dose is too high in relation to the insulin requirement.
Tabulated list of adverse reactions: The following related adverse reactions from clinical investigations are listed below by system organ class and in order of decreasing incidence (very common: ≥1/10; common: ≥1/100 to <1/10; uncommon: ≥1/1,000 to <1/100; rare: ≥1/10,000 to <1/1,000; very rare: <1/10,000; not known: cannot be estimated from the available data).
Within each frequency grouping, adverse reactions are presented in order of decreasing seriousness. (See Table 4.)

Description of selected adverse reactions: Metabolism and nutrition disorders: 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.
Immune system disorders: 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. In Toujeo clinical studies in adult patients, the incidence of allergic reactions was similar in Toujeo-treated patients (5.3%) and insulin glargine 100 units/ml-treated patients (4.5%).
Eyes disorders: 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.
Skin and subcutaneous tissue disorders: Lipodystrophy and cutaneous amyloidosis may occur at the injection site and delay local insulin absorption. Continuous rotation of the injection site within the given injection area may help to reduce or prevent these reactions (see Precautions).
General disorders and administration site conditions: Injection site 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. In Toujeo clinical studies in adult patients, the incidence of injection site reactions was similar in Toujeo-treated patients (2.5%) and insulin glargine 100 units/ml-treated patients (2.8%).
Rarely, insulin may cause oedema particularly if previously poor metabolic control is improved by intensified insulin therapy.
Paediatric population: Safety and efficacy of Toujeo have been demonstrated in a study in children aged 6 to less than 18 years. The frequency, type and severity of adverse reactions in the paediatric population do not indicate differences to the experience in the general diabetes population (see Pharmacology: Pharmacodynamics under Actions). Clinical study safety data are not available for children under 6 years.
Other special populations: Based on the results from clinical studies, the safety profile of Toujeo in elderly patients and in patients with renal impairment was similar to that of the overall population (see Pharmacology: Pharmacodynamics under Actions).
Reporting of suspected adverse reactions: Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the national reporting system.
