4). Starting dose The recommended starting dose is 8 mg/day (4 mg twice a day) for four weeks. Maintenance dose The tolerance and dosing of galantamine should be reassessed on a regular basis, preferably within three months after start of treatment.
Thereafter, the clinical benefit of galantamine and the patient's tolerance of treatment should be reassessed on a regular basis according to current clinical guidelines. Maintenance treatment can be continued for as long as therapeutic benefit is favourable and the patient tolerates treatment with galantamine.
Discontinuation of galantamine should be considered when evidence of a therapeutic effect is no longer present or if the patient does not tolerate treatment. The initial maintenance dose is 16 mg/day (8 mg twice a day) and patients should be maintained on 16 mg/day for at least 4 weeks.
An increase to the maintenance dose of 24 mg/day (12 mg twice a day) should be considered on an individual basis after appropriate assessment including evaluation of clinical benefit and tolerability. In individual patients not showing an increased response or not tolerating 24 mg/day, a dose reduction to 16 mg/day should be considered.
g. in preparation for surgery). 2). For patients with a creatinine clearance ≥9 ml/min, no dosage adjustment is required. 3). 2). In patients with moderately impaired hepatic function (Child-Pugh score 7-9), based on pharmacokinetic modelling, it is recommended that dosing should begin with 4 mg once daily, preferably taken in the morning, for at least 1 week.
Thereafter, patients should proceed with 4 mg twice-daily for at least 4 weeks. In these patients, daily doses should not exceed 8 mg twice-daily. 3). No dosage adjustment is required for patients with mild hepatic impairment. 5). Paediatric population There is no relevant use of galantamine in the paediatric population.

The table below reflects data obtained with galantamine in seven placebo- controlled, double-blind clinical trials (N=6,502), five open-label clinical trials (N=1,454), and from postmarketing spontaneous reports. The most commonly reported adverse drug reactions were nausea (21%) and vomiting (11%).
They occurred mainly during titration periods, lasted less than a week in most cases and the majority of patients had one episode. Prescription of anti-emetics and ensuring adequate fluid intake may be useful in these instances. Frequency estimate: very common (≥ 1/10); common (≥ 1/100 to < 1/10); uncommon (≥ 1/1000 to < 1/100); rare (≥ 1/10,000 to <1/1000); and very rare (<1/10,000).
4) Reporting of suspected adverse reactions Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continuing monitoring of the benefit/ risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme.

3%) patients on placebo. The deaths were due to various causes. About half of the galantamine deaths appeared to result from various vascular causes (myocardial infarction, stroke, and sudden death). The relevance of this finding for the treatment of patients with Alzheimer dementia is unknown.
No increased mortality in the galantamine group was observed in a long-term, randomized, placebo-controlled study in 2045 patients with mild to moderate Alzheimer´s disease. The mortality rate in the placebo group was significantly higher than in the galantamine group.
