Expired ointments should never be used again. If you use an expired ointment, on the one hand, the drug will not have the therapeutic effect it should have, and on the other hand, some serious or potential adverse reactions may occur, which may cause redness and swelling as well as itching and inflammation of the skin where it is applied. When using the ointment must be used within the expiration date of the ointment, but also pay attention to whether the ointment is stored in strict accordance with the storage conditions in the instructions of the ointment. If the cream is not stored in strict accordance with the storage conditions in the instructions, it is not recommended to use the cream even though it is within the expiration date.
