A company says more of its products for infant ibuprofen, which could result in health problems, should be recalled.The oral pain-reliever drops are connected with CVS Pharmacy, Walmart and Family Dollar stores and could lead to adverse health effects, such as vomiting and gastrointestinal bleeding.The issue relates to the product potentially having higher concentrations of ibuprofen than it should.The recalled products now apply to certain 1/2 ounce and 1 ounce bottles with February, April, August and December expiration dates for this year.The voluntary recall comes from Tris Pharma, Inc., which manufactures the drugs that are eventually sold by retailers. According to a notice, no serious adverse events have been reported.
