What is Alitretinoin: Uses, Dosage, Side Effects and More

Alitretinoin is a topical retinoid medication that helps treat severe chronic hand eczema when other treatments haven't worked well enough. It's a form of vitamin A that works by reducing inflammation and helping your skin cells grow and shed more normally.

This medication belongs to a class of drugs called retinoids, which are derivatives of vitamin A. Think of alitretinoin as a targeted helper that goes directly to the problem areas on your hands to calm down the overactive immune response that causes eczema symptoms.

What is Alitretinoin Used For?

Alitretinoin is specifically designed to treat severe chronic hand eczema in adults. Your doctor will typically recommend this medication when your hand eczema has been ongoing for months or years and hasn't responded well to other treatments like topical steroids or moisturizers.

The medication works particularly well for hand eczema that causes thick, scaly patches, painful cracks, and persistent itching. It's especially helpful when the eczema affects your ability to use your hands for daily activities like work or household tasks.

Sometimes doctors may consider alitretinoin for other forms of severe eczema, but hand eczema remains its primary and most well-studied use. The medication has shown good results in clinical studies for people whose hand eczema significantly impacts their quality of life.

How Does Alitretinoin Work?

Alitretinoin works by binding to specific receptors in your skin cells called retinoid receptors. This binding process helps regulate how your skin cells grow, divide, and shed, which can reduce the thick, scaly patches that characterize severe hand eczema.

The medication also has anti-inflammatory properties, meaning it helps calm down the overactive immune response in your skin. This dual action helps address both the visible symptoms and the underlying inflammation that drives chronic hand eczema.

As a moderately strong retinoid, alitretinoin is more potent than over-the-counter retinol products but generally gentler than some other prescription retinoids. Most people start seeing improvements within 12 to 24 weeks of consistent use, though some may notice changes sooner.

How Should I Take Alitretinoin?

You should apply alitretinoin gel directly to the affected areas of your hands once daily, preferably in the evening. Start with clean, dry hands and apply a thin layer of the gel only to the areas with eczema, avoiding healthy skin when possible.

After applying the medication, wash your hands thoroughly to remove any excess gel from your palms and fingers. This helps prevent accidentally transferring the medication to other parts of your body, especially your face or eyes.

You don't need to take alitretinoin with food since it's applied topically rather than taken by mouth. However, it's best to apply it when you won't be washing your hands frequently, which is why evening application works well for most people.

Wait at least 15 minutes after applying the gel before using hand cream or moisturizer. This gives the medication time to absorb properly into your skin.

How Long Should I Take Alitretinoin For?

Most people use alitretinoin for 12 to 24 weeks to see significant improvement in their hand eczema. Your doctor will typically have you try it for at least 12 weeks before deciding if it's working well enough to continue.

If your hand eczema improves significantly during this time, your doctor might recommend continuing the treatment for up to 24 weeks total. Some people may need longer treatment periods, especially if their eczema is particularly severe or long-standing.

After your initial treatment course, your doctor will assess whether you need ongoing maintenance therapy. Some people can stop using alitretinoin once their eczema clears, while others may need periodic treatment courses to prevent flare-ups.

What Are the Side Effects of Alitretinoin?

Like all medications, alitretinoin can cause side effects, though many people tolerate it well when used as directed. The most common side effects occur at the application site and are usually mild to moderate.

Here are the side effects you might experience, starting with the most common ones:

• Skin irritation, redness, or burning at the application site
• Dry skin or peeling in the treated areas
• Itching or stinging sensation when first applied
• Increased sensitivity to sunlight in treated areas
• Temporary darkening or lightening of the skin

These local skin reactions often improve as your skin adjusts to the medication over the first few weeks of use. Most people find these effects manageable and temporary.

Less common but more serious side effects can include severe skin irritation, allergic reactions, or worsening of your eczema symptoms. If you experience severe burning, swelling, or signs of an allergic reaction like hives or difficulty breathing, contact your doctor immediately.

Rare but important side effects include significant changes in skin pigmentation or signs of skin infection in the treated areas. While these are uncommon, they require prompt medical attention if they occur.

Who Should Not Take Alitretinoin?

Alitretinoin isn't suitable for everyone, and certain conditions make it unsafe or less effective. Your doctor will review your medical history carefully before prescribing this medication.

You should not use alitretinoin if you're pregnant, planning to become pregnant, or breastfeeding. Retinoids can cause serious birth defects, so reliable contraception is essential for women of childbearing age using this medication.

People with known allergies to retinoids or any ingredients in the alitretinoin gel should avoid this medication. If you've had severe reactions to other vitamin A derivatives, let your doctor know before starting treatment.

Those with certain skin conditions like severe sunburn, eczema herpeticum, or active skin infections in the treatment area should wait until these conditions resolve before using alitretinoin.

Alitretinoin Brand Names

Alitretinoin is available under the brand name Toctino in many countries, though availability varies by region. In some areas, it may be available under different brand names or as a generic formulation.

Your pharmacist can help you identify the specific brand or generic version available in your location. The active ingredient remains the same regardless of the brand name, but inactive ingredients may vary slightly between manufacturers.

Alitretinoin Alternatives

If alitretinoin doesn't work well for you or causes intolerable side effects, several alternative treatments exist for severe hand eczema. Your doctor can help you explore these options based on your specific situation.

Topical alternatives include potent corticosteroids like clobetasol, calcineurin inhibitors such as tacrolimus or pimecrolimus, and newer treatments like topical JAK inhibitors. Each has different strengths and potential side effects.

For severe cases, systemic treatments like oral corticosteroids, methotrexate, or cyclosporine might be considered. Phototherapy using UV light can also be effective for some people with chronic hand eczema.

Newer options include dupilumab injections, which target specific immune pathways involved in eczema. Your dermatologist can discuss which alternatives might work best for your particular type of hand eczema.

Is Alitretinoin Better Than Tacrolimus?

Both alitretinoin and tacrolimus are effective treatments for hand eczema, but they work in different ways and may be better suited for different people. The choice between them depends on your specific symptoms, medical history, and treatment goals.

Alitretinoin tends to be more effective for hyperkeratotic (thick, scaly) hand eczema, while tacrolimus often works better for inflammatory types with more redness and swelling. Some people respond better to one medication than the other.

Tacrolimus can be used for longer periods and doesn't carry the same pregnancy risks as alitretinoin. However, alitretinoin may provide more dramatic improvements in severe cases that haven't responded to other treatments.

Your doctor will consider factors like your age, pregnancy plans, severity of symptoms, and previous treatment responses when deciding between these options. Sometimes, they might recommend trying one first and switching if needed.
