| In five large long-term clinical trials over 2,500 patients have received treatment with Victoza alone or in combination with metformin, a sulphonylurea (with or without metformin) or metformin plus rosiglitazone.Frequencies are defined as: 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, undesirable effects are presented in order of decreasing seriousness.The most frequently reported adverse reactions during clinical trials were gastrointestinal disorders: nausea and diarrhoea were very common, whereas vomiting, constipation, abdominal pain, and dyspepsia were common. At the beginning of Victoza therapy, these gastrointestinal adverse reactions may occur more frequently. These reactions usually diminish within a few days or weeks on continued treatment. Headache and nasopharyngitis were also common. Furthermore, hypoglycaemia was common, and very common when Victoza is used in combination with a sulphonylurea. Major hypoglycaemia has primarily been observed when combined with a sulphonylurea.Table 1 lists related adverse reactions identified from Phase III combination-studies with Victoza. The table presents adverse reactions that occurred with a frequency >5% if the frequency was higher among Victoza-treated patients than patients treated with comparator. The table also includes adverse reactions with a frequency 2% if the frequency was >2 times the frequency for comparator-treated subjects.Table 1 Adverse reactions identified from long-term controlled phase III studies and spontaneous reports | Adverse reaction | Frequency of adverse reaction by treatment group | | | Liraglutide with metformin | Liraglutide with glimepiride | Liraglutide with metformin and glimepiride | Liraglutide with metformin and rosiglitazone | Spontaneous reports | | Infections and infestations | | | | | | | Nasopharyngitis

| * Does not conform to criteria previously cited but is considered a listed adverse reaction.#See section 4.4 (special warnings and precautions for use)In a clinical trial with Victoza as monotherapy rates of hypoglycaemia reported with Victoza were lower than rates reported for patients treated with active comparator (glimepiride). The most frequently reported adverse events were gastrointestinal and infections and infestations.Hypoglycaemia Most episodes of confirmed hypoglycaemia in clinical studies were minor. No episodes of major hypoglycaemia were observed in the study with Victoza used as monotherapy. Major hypoglycaemia may occur uncommonly and has primarily been observed when Victoza is combined with a sulphonylurea (0.02 events/subject year). Very few episodes (0.001 events/subject year) were observed with administration of Victoza in combination with oral antidiabetics other than sulphonylureas.Gastrointestinal adverse reactions When combining Victoza with metformin, 20.7% of patients reported at least one episode of nausea, and 12.6% of patients reported at least one episode of diarrhoea. When combining Victoza with a sulphonylurea, 9.1% of patients reported at least one episode of nausea and 7.9% of patients reported at least one episode of diarrhoea. Most episodes were mild to moderate and occurred in a dose-dependent fashion. With continued therapy, the frequency and severity decreased in most patients who initially experienced nausea.Patients >70 years may experience more gastrointestinal effects when treated with liraglutide.Patients with mild renal impairment (creatinine clearance 60-90 ml/min) may experience more gastrointestinal effects when treated with liraglutide.Withdrawal The incidence of withdrawal due to adverse reactions was 7.8% for Victoza-treated patients and 3.4% for comparator-treated patients in the long-term controlled trials (26 weeks or longer). The most frequent adverse reactions leading to withdrawal for Victoza-treated patients were nausea (2.8% of patients) and vomiting (1.5%).Immunogenicity Consistent with the potentially immunogenic properties of medicinal products containing proteins or peptides, patients may develop anti-liraglutide antibodies following treatment with Victoza. On average, 8.6% of patients developed antibodies. Antibody formation has not been associated with reduced efficacy of Victoza.Few cases (0.05%) of angioedema have been reported during all long-term clinical trials with Victoza.Injection site reactions Injection site reaction has been reported in approximately 2% of subjects receiving Victoza in long-term (26 weeks or longer) controlled trials. These reactions have usually been mild.Pancreatitis Few cases (<0.2%) of acute pancreatitis have been reported during long-term clinical trials with Victoza.Thyroid events The overall rates of thyroid adverse events in all intermediate and long-term trials are 33.5, 30.0 and 21.7 events per 1,000 subject years of exposure for total liraglutide, placebo and total comparators; 5.4, 2.1 and 1.2 events, respectively concern serious thyroid adverse events.Thyroid neoplasms, increased blood calcitonin and goiters were the most frequently thyroid adverse events. The rates per 1,000 subject years of exposure were 6.8, 10.9 and 5.4 of liraglutide treated patients in comparison with 6.4, 10.7 and 2.1 of placebo treated and 2.4, 6.0 and 1.8 of total comparator treated patients respectively. | |
