Protopic (tacrolimus) is a prescription ointment used to treat moderate to severe eczema when other treatments haven’t worked well enough. It helps calm the skin by reducing the immune reaction that causes redness, itching, and inflammation. Tacrolimus works at the source of eczema flares instead of just masking symptoms. By managing the skin’s overactive immune response, it helps prevent itchy, dry patches from getting worse and keeps symptoms under better control over time.
Apply Protopic ointment as a thin layer to the affected skin areas twice daily and rub it in gently. Do not cover the treated areas with bandages or wraps unless a doctor instructs otherwise. The medication comes in two strengths: 0.03% and 0.1%.
For adults and children 16 years and older, use the 0.03% or 0.1% ointment twice daily.
For children 2 to 15 years old, use only the 0.03% strength twice daily.
Wash your hands before applying the ointment unless you're treating the hands. After application, wait at least 2 hours before washing the treated area. Don't apply the medication right after bathing or showering, as the skin needs to be completely dry first.
The medication can be used on most body areas, including the face, neck, and skin folds. If there's no improvement after 6 weeks of treatment, contact a healthcare provider to reassess the condition.
The active ingredient in Protopic is tacrolimus.
Avoid taking or using this medication if any of the following apply:
Common side effects of Protopic include:
What is Protopic Ointment used for?
Protopic Ointment is a prescription topical medication used to treat moderate to severe atopic dermatitis (eczema) in patients who have not responded well to other treatments. It helps reduce inflammation, itching, and redness associated with eczema.
How does Tacrolimus in Protopic work?
Tacrolimus is a calcineurin inhibitor that works by suppressing the immune response that causes skin inflammation. It blocks the activity of T-cells, which are involved in the inflammatory process of eczema.
Who can use Protopic Ointment?
Protopic is approved for adults and children aged 2 years and older. The 0.03% strength is typically used for children aged 2 to 15, while both 0.03% and 0.1% strengths can be used in adults, depending on the severity of the condition.
How should Protopic Ointment be applied?
Apply a thin layer of the ointment to affected skin areas twice daily, usually in the morning and evening. Wash hands before and after applying unless treating the hands themselves. It should not be applied under bandages or occlusive dressings.
What are the common side effects of Protopic?
The most common side effects include burning, stinging, or itching at the application site, especially during the first few days of use. Less common effects may include skin redness, acne, or flu-like symptoms.
Are there serious risks associated with Protopic?
There is a theoretical risk of increased cancer, including skin cancer and lymphoma, though a direct link has not been conclusively established. The FDA has issued a boxed warning, and long-term safety beyond one year is not well established.
Can Protopic be used on all areas of the body?
Protopic should not be used on mucous membranes (inside the nose, mouth, or eyes) or on broken or infected skin. It is also not recommended for use in areas with active viral infections such as cold sores or warts.
Can you use Protopic with other skin products?
You can use moisturizers, but they should be applied after Protopic, ideally 2 hours later. Avoid using other topical treatments on the same area unless advised by a healthcare provider.
Should sun exposure be avoided while using Protopic?
Yes, patients using Protopic should minimize exposure to sunlight, tanning beds, and phototherapy. Tacrolimus may make the skin more sensitive to UV light, increasing the risk of sunburn or long-term damage.
Is Protopic a steroid?
No, Protopic is not a steroid. It is a non-steroidal immunomodulator, which makes it a useful alternative for patients who cannot tolerate or have not responded to topical corticosteroids.
A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, consumption method, performance, and intended use. Before generics become available on the market, the generic company must prove it has the same active ingredients as the brand-name drug and works in the same way and in the same amount of time in the body.
The only differences between generics and their brand-name counterparts is that generics are less expensive and may look slightly different (e.g., different shape or color), as trademark laws prevent a generic from looking exactly like the brand-name drug.
Generics are less expensive because generic manufacturers don't have to invest large sums of money to develop a drug. When the brand-name patent expires, generic companies can manufacture a copy of the brand-name and sell it at a substantial discount.
