Consolidation is a common way to deal with credit card debt. If you have several credit cards, you may be able to obtain a consolidation loan at a lower rate. Just be sure to check the full terms and conditions. Even if the rate is lower, if the loan term is longer, you will end up paying more in the long term.
If you have good credit and a smaller amount of credit card debt, you may be able to consolidate into a new card, with preferential terms. If you obtain a card with a 0% introductory rate, it will allow you to concentrate on bringing down the card balance without needing to cover any interest.
