Carac is a topical cream that contains the active ingredient fluorouracil, which belongs to a class of medications known as antimetabolites. This medication is commonly used in the treatment of certain types of skin conditions, such as actinic keratoses, a precancerous skin condition caused by sun exposure.

When applied to the affected area, Carac works by interfering with the growth of abnormal skin cells, ultimately leading to their destruction. This process helps to reduce the risk of these cells developing into skin cancer.

It is important to follow the instructions provided by your healthcare provider when using Carac. Typically, the cream is applied once or twice daily for a specified period of time. It is important to avoid applying the cream to healthy skin surrounding the affected area, as it may cause irritation.

Some common side effects of Carac may include redness, swelling, and peeling of the skin at the application site. These side effects are usually temporary and will improve once treatment is completed. However, if you experience severe irritation or any other concerning symptoms, it is important to contact your healthcare provider.

Before using Carac, it is important to inform your healthcare provider about any other medications or supplements you are taking, as well as any allergies you may have. Additionally, it is important to avoid prolonged sun exposure while using Carac, as it may increase the risk of skin irritation.

Overall, Carac can be an effective treatment option for certain skin conditions when used as directed by a healthcare professional. If you have any questions or concerns about this medication, do not hesitate to speak with your healthcare provider.
