(CNN) A recall has been issued for infant ibuprofen sold by CVS, Family Dollar and Walmart, Tris Pharma said this week.

The three recalled lots of Concentrated Oral Suspension, USP (NSAID) 50 mg per 1.25 mL may have concentrations of ibuprofen that are too high and therefore could be dangerous, according to the recall announcement.

Some recalled ibuprofen was sold at Walmart.

The recalled medication was also sold at CVS.

The over-the-counter liquid pain reliever and fever reducer is meant for infants who are between the ages of 6 months and 23 months old. Adverse events from the medication may include nausea, vomiting, upper abdominal pain, diarrhea, gastrointestinal pain, ringing in the ears and headache, although no adverse events related to the recalled ibuprofen have been reported, according to Tris Pharma.

"There is a remote possibility that infants, who may be more susceptible to a higher potency level of drug, and therefore may be more vulnerable to permanent NSAID-associated renal injury," the recall announcement said.

The recalled medications were 0.5 ounce bottles sold nationwide at CVS, Family Dollar and Walmart stores.
