Hvis bisphosphonater eller natriumflourid anvendes samtidigt, bør dette lægemiddel tages mindst 3 timer før indtagelsen af Calcitugg (og tilhørende navne), da den gastrointestinale absorption kan være nedsat.
If a bisphosphonate or sodium fluoride is used concomitantly, this preparation should be administered at least three hours before the intake of Calcitugg (and associated names) since gastrointestinal absorption may be reduced.
