Carac Cream (Fluorouracil)
What is Carac Cream (Fluorouracil) ?
Carac is a topical cream with the active ingredient fluorouracil and is intended for dermatological use. This medication is classified as an antineoplastic metabolite. Carac cream is indicated for actinic or solar keratosis. These skin lesions come around after years of excessive exposure to the sun and display as scaly and dry patches of skin. Although not all solar keratotic lesions are harmful, some of these lesions could become skin cancer. Fluorouracil can also be used for superficial basal cell carcinoma, a type of skin cancer. Basal cell carcinoma lesions often come around skin areas exposed to the sun, like the face. Such lesions are characterized by a shiny, bumped, colored skin area. Carac cream is prescribed for basal cell carcinoma when other conventional methods have proved insufficient. In addition, carac cream could be prescribed in case of multiple basal cell carcinoma lesions or sites that are difficult to treat. If untreated, basal cell carcinoma can become invasive and grow, with aggressive cases spreading to other body parts other than the skin.
The location of basal cell carcinoma and solar keratotic lesions can vary from the scalp, face, hands, forearms, and chest, amongst many others.
How does Carac cream work?
Fluorouracil works on cancer cells by inhibiting the production of DNA in these cells. This inhibition prevents the cancer cell from multiplying and producing vital proteins for its growth. In addition, fluorouracil will mask itself as purine, a DNA building block. In this manner, these substances will not be incorporated into the cell’s DNA in the cell cycle. This will seize normal cell development and division. All this leads to the death of such cells.
Dosage
Carac cream comes in 0.5% of fluorouracil
For actinic keratosis, Carac cream is usually prescribed twice daily for 2 to 4 weeks.
Carac cream is usually prescribed twice daily for 3 to 6 weeks for superficial basal cell carcinoma.
How to Use Carac Cream
Carac cream is usually applied twice a day. However, the duration of the treatment depends on what your doctor deems fit and the condition for which it is being prescribed.
To help you remember, try applying Carac cream around the same each day.
Apply Carac cream as prescribed by your doctor and at the specified frequency.
Wash the area to be treated with water only and dry it. Wait 10 minutes before you apply the cream. Then, apply Carac cream with an applicator. Such applicator must not be made of metal. Suppose you are using your hands to apply; either wear a glove or wash your hands immediately after you are done. Leave the treated areas uncovered unless your doctor tells you otherwise. If you are advised to cover the treated area, be sure to use porous gauze dressings, allowing the site to breathe.
Carac cream should not be applied to the eyelids, eyes, mouth, nose, vagina, or mucous areas.
Apply sufficient amounts of cream that cover the area to be treated.
How to store Carac cream?
Store this cream in its original container, at room temperature, and out of reach for children or pets. Keep it away from excess heat or moisture. Carac cream can be fatal for pets. Seek veterinary care if your pet licks or ingests Carac cream. Avoid storing this medication in the bathroom.
Overdose
Since Carac cream requires topical application, topical overdose is less likely to cause acute problems. However, vomiting and gastric lavage may be necessary if Carac cream is ingested. In addition, if Carac cream comes in contact with the eyes, it is essential to flush with plenty of water. If you think you misused this medication as described above, feel like passing out, or experience difficulty breathing, it is crucial to call 911 or contact the poison control center.

Precautions
If you have a reaction to capecitabine or flucytosine, tell your doctor.
Avoid sunlight while using Carac cream. Direct exposure to sunlight between 10:00 am, and 2:00 pm should be avoided. Sun exposure increases side effects. Wear high SPF sunscreen, a hat, protective clothing, and sunglasses when sun-exposed, and use Carac cream.
Speak to your doctor if you get sunburned or develop skin blisters or redness.
Leave a 2-hour interval before applying sunscreen or any moisturizers.
Consult your doctor before using other topical creams or lotions while on Carac cream.
Avoid ultraviolet light like tanning booths and sunlamps while using Carac cream.
Ulcerated skin increases absorption and may result in inflamed skin and heightened side effects.
Avoid applying Carac cream at night before going to bed, as it may rub on your pillowcase and come in contact with your eyes.
Avoid applying Carac cream before any physical activity because sweat may cause the cream to come in contact with your eyes.
Warnings
Carac cream should not be used in children under the age of 18 years.
Do not breastfeed while using Carac cream. It is unknown if fluorouracil passes through breast milk.
Suppose you become pregnant or conceive while on this treatment; stop using Carac cream and speak to your doctor. Use effective birth control methods while on Carac cream.

Contraindications
Carac cream is contraindicated in:
- Pregnant women or those planning to

- Patients with dihydropyrimidine dehydrogenase enzyme deficiencies are also referred to as DPD deficiencies. This enzyme mostly catabolizes fluorouracil. Therefore, the lack of this enzyme can lead to fluorouracil toxicity. In addition, individuals with DPD deficiency could develop stomatitis, erythema, skin rash, neutropenia, thrombocytopaenia, inflamed esophagus, stomach, and small intestine.
- Individuals who are allergic or have a hypersensitivity to fluorouracil or any of its excipients
