The remedies for a credit card that is 5 days overdue are as follows:

First, pay off the overdue amount immediately, including principal and interest, to reduce losses caused by overdue payments.

Secondly, contact the card-issuing bank to explain the reason for the overdue payment and request an extension of the repayment period or an installment plan. Sincerely express your willingness to improve your repayment ability and strive for the bank's understanding and support.

In addition, update your personal contact information in a timely manner to ensure that the bank can communicate with you effectively and avoid missing any important notifications.

Summary: After a credit card is overdue for 5 days, the most important thing is to repay the debt immediately and actively communicate with the card-issuing bank to find a cooperative solution. At the same time, maintaining a good credit record and updating personal information in a timely manner can help avoid similar problems from happening again.
