Eucrisa (Generic Crisaborole): Complete Medication Guide
Key Takeaways
Crisaborole is a topical ointment that reduces inflammation and itching in atopic dermatitis (eczema).
Applied directly to affected skin twice daily, it works without the steroid side effects of traditional treatments.
Common mild side effects include skin irritation, burning, or stinging at the application site.
Generic crisaborole offers the same active ingredient as brand-name Eucrisa at a lower cost.
Always discuss treatment options with your healthcare provider before starting any new medication.
Eucrisa (Generic Crisaborole) Overview
Crisaborole is a topical medication belonging to a class of drugs called phosphodiesterase-4 (PDE-4) inhibitors. It comes as a cream or ointment applied directly to the skin. The medication works by reducing inflammation and calming the immune response in the skin, which helps relieve itching and redness associated with atopic dermatitis—a common condition often called eczema.
Atopic dermatitis causes the skin to become dry, itchy, and inflamed. It can significantly impact quality of life, making everyday activities uncomfortable. Crisaborole provides relief without the systemic effects of oral medications or the long-term concerns of topical steroids. Generic vs Brand Name Drugs explains how generic versions contain the same active ingredient as brand-name alternatives at lower prices.
The generic version of crisaborole became available after the patent for Eucrisa expired, making this effective treatment more accessible to patients. Generic medications offer cost-effective alternatives without compromising effectiveness. If you're managing eczema, discussing crisaborole with your clinician can help determine if it's the right option for your skin condition.

Side Effects
Crisaborole is generally well-tolerated when applied to the skin as directed. Most side effects are mild and occur at the application site. Serious side effects are rare but possible.
Common Side Effects
Skin burning or stinging – A temporary sensation at the application site that usually improves with continued use
Itching or irritation – Localized itching or mild irritation where the ointment is applied
Skin redness – Increased redness at the application area, separate from the underlying eczema
Folliculitis – Inflammation of hair follicles appearing as small bumps or pustules on treated areas
Worsening of eczema – Temporary flares before improvement, which may occur as inflamed skin begins to heal
Serious Side Effects
Severe allergic reaction – Rare anaphylaxis or severe rash indicating an allergy to crisaborole or inactive ingredients
Herpetic infections – Increased risk of cold sore or herpes outbreaks on treated skin areas
Widespread infection – Signs of bacterial or fungal infection spreading beyond the application site
Systemic absorption effects – Rare cases where the medication enters the bloodstream, causing headache, joint pain, or fever
Hypersensitivity reaction – Severe swelling, difficulty breathing, or severe skin reaction suggesting allergic response
When to Seek Medical Attention
Contact your healthcare provider if you experience severe burning, spreading infection, signs of an allergic reaction (swelling, difficulty breathing), or if your eczema worsens significantly after a few weeks of treatment. If side effects are mild and temporary, they often resolve as your skin adjusts to the medication.
Seek immediate emergency care if you develop signs of a severe allergic reaction, such as throat tightness or difficulty breathing. Most patients tolerate crisaborole well, and side effects typically improve with consistent use.

Important: Do not stop using crisaborole without discussing it with your doctor, even if your skin improves. Stopping suddenly may cause eczema to flare again. If you miss a dose, simply apply it as soon as you remember unless it's nearly time for your next dose—then skip the missed dose. Do not apply extra ointment to make up for a missed dose. Wash your hands after application unless treating your hands.
Drug Interactions
Crisaborole is a topical medication with minimal systemic absorption, meaning it enters the bloodstream in very small amounts. As a result, drug interactions are uncommon. However, certain substances may still warrant caution.
Other Topical Medications
Applying crisaborole with other topical treatments (especially other eczema medications or antibiotics) may increase skin irritation or reduce effectiveness of either drug. Space applications 15 minutes apart and discuss your entire skincare routine with your clinician.
Oral Immunosuppressants
If you take medications like tacrolimus or cyclosporine for eczema, combining them with crisaborole may increase immune suppression. Your doctor can monitor this combination safely, but it's important to report all medications you're taking.
CYP3A4 Inhibitors
Medications that inhibit the CYP3A4 enzyme (such as ketoconazole or erythromycin) could theoretically increase crisaborole blood levels, though clinical significance is minimal with topical use. Inform your pharmacist of all medications to ensure safety.
Live Vaccines
Since crisaborole may slightly affect immune function when absorbed systemically, discuss timing of live vaccines (like varicella or rotavirus) with your doctor. This is most relevant for young children or those on high-dose topical crisaborole over large skin areas.

Frequently Asked Questions
Get answers to common questions about crisaborole.
Most patients notice improvement in itching and redness within 1–2 weeks of consistent twice-daily application. Full benefit may take 4 weeks or longer. Consistency is key—missing doses delays improvement. If you don't see meaningful improvement after 4 weeks, discuss with your clinician about adjusting your treatment plan or trying alternative options.
Yes, crisaborole is approved for use on all body areas, including the face, neck, and skin folds. The face and sensitive areas may experience more stinging initially, so start with a test area if concerned. If burning is intolerable, reduce frequency to once daily until skin adjusts, then return to twice daily as tolerated.
Yes, generic crisaborole contains the same active ingredient and works identically to Eucrisa. Generic vs. Brand-Name Drugs shows that generic versions undergo rigorous testing to ensure equal effectiveness. The main difference is cost—generic versions are significantly cheaper.
Crisaborole can be combined with other treatments like moisturizers, antihistamines, or even other topical medications under your doctor's guidance. However, avoid applying multiple topical drugs simultaneously without spacing them 15 minutes apart. Discuss your full treatment plan with your clinician to ensure safety and prevent interactions or excessive irritation.
Stop using the medication immediately and seek medical attention if you experience severe allergic reactions (swelling, difficulty breathing), widespread infection, or severe skin worsening. Mild burning or stinging usually improves with continued use, but severe reactions warrant urgent evaluation. Contact your doctor or visit an urgent care center for guidance.
