The bismuth in this medicine may cause severe constipation in children.
In addition, do not use this medicine to treat nausea or vomiting in children or teenagers who have or are recovering from the flu or chickenpox. If nausea or vomiting is present, check with the child's doctor immediately because this could be an early sign of Reye's syndrome.
Geriatric
