Consumers can use expired ibuprofen, but the potency of ibuprofen cannot be guaranteed by the manufacturer after the expiration date. Many medications are safe for use up to one year after they expire, but it varies with environmental conditions, according to Drugs.com.
If expired medications such as ibuprofen are used for minor aches and pains, they may not be harmful, but they do gradually loose their potency, according to Drugs.com. Do not take a higher dose than the package recommends. Store pills in a cool, dry place in a tightly closed container as heat and humidity can deteriorate the pills. Consult a physician about how to best handle expired ibuprofen.
