What Is Protopic (tacrolimus)?
Topical calcineurin inhibitors are medications that are applied to the skin that are used in the treatment of atopic dermatitis (AD). Topical calcineurin inhibitors are usually prescribed as second-line treatment, which means they are used after primary treatment with other topical medications, like corticosteroids, has already been tried and has not sufficiently improved symptoms of AD.1
What is Protopic?
Protopic is a prescription topical medication used to treat moderate to severe AD in adults and children over the age of 2. Protopic ointment should only be used for short-term and non-continuous use in individuals who do not have compromised immune systems and who have already tried other topical treatments for their AD or those who cannot use other treatments.2 The active ingredient in Protopic is tacrolimus.2
How does Protopic work?
Topical calcineurin inhibitors like Protopic, block calcineurin, a naturally produced chemical that activates T-cells. T-cells are a type of white blood cell involved in the immune system response. In AD, there is a dysfunction in the immune system causing excessive inflammation in the skin. Topical calcineurin inhibitors block cytokines (chemical messengers) that trigger the inflammatory response. Once absorbed into the skin, topical calcineurin inhibitors reduce symptoms of AD like redness and itchiness.1,2
What are the possible side effects of Protopic?
Common side effects experienced by patients using Protopic include skin burning or stinging when first applied. These side effects tend to lessen after several applications of the medication. People with acute or severe AD are at risk for infections in the areas of skin compromised by AD. Because of the immunosuppressant effects of Protopic, it is not recommended for use in people who have active skin infections.
Although no causal relationship has been established, he United States Food and Drug Administration has issued a black box warning that rare cases of cancer (skin cancer and lymphoma) have been reported in patients using topical calcineurin inhibitors including Protopic.1,2
These are not all the possible side effects of Protopic. Patients should talk to their doctor about what to expect with treatment with Protopic.
