The Hidden Dangers of Topical Steroids: Unmasking the 7 Potency Classes

Topical corticosteroids (TCS) are potent medications available in various formulations (ointments, creams, lotions, etc.) and classified into seven potency classes, ranging from mild to super potent. The formulation can influence a steroid's potency, with ointments generally being stronger than creams or lotions.

Prolonged or inappropriate use of TCS can lead to Topical Steroid Withdrawal (TSW). TSW can mimic worsening eczema, and is often misdiagnosed as severe eczema. Understanding how steroid potency and formulation influence symptoms is crucial for managing both the initial condition and potential withdrawal.

Steroid Potency: The 7 Classes

Steroids are categorized into seven classes based on their potency, ranging from super potent (Class 1) to low potency (Class 6 and 7). The higher the potency, the stronger its anti-inflammatory effects, but also the greater risk of side effects and withdrawal symptoms.

Unveiling the Impact of Topical Steroid Potency on Withdrawal Symptoms

Topical steroid withdrawal (TSW) symptoms vary widely depending on the potency of the corticosteroid used and the individual's unique response. While there's no one-size-fits-all experience, understanding the general patterns linked to potency can help you anticipate and manage potential withdrawal effects.

To quickly identify the potency class of your topical steroid, leverage the power of AI-powered tools like ChatGPT. Simply type the name and formula of your steroid into the chat, and the AI can provide you with its classification.

For example, you can ask:
"What potency class is Betamethasone Valerate 0.12%?"

High Potency Steroids: Class 1, 2, 3

High-potency steroids like clobetasol propionate (Temovate) or betamethasone dipropionate (Diprolene) are known to suppress inflammation rapidly and effectively. However, this very strength can backfire upon withdrawal. The skin, having grown dependent on external cortisol, may erupt in a fiery storm of symptoms:

• Erythema and Edema: Intense redness, swelling, and a burning sensation that can feel like a sunburn.

• Oozing and Crusting: In severe cases, the skin may weep fluid, forming crusts that can crack and bleed.

• Flaking and Shedding: The skin's outer layer may peel off in large sheets, resembling a snake shedding its skin.

• Intense Itching: Often described as unbearable, this itch can disrupt sleep and lead to skin damage from scratching.

• Nerve Pain and Sensitivity: Some individuals experience shooting or burning pain, along with heightened sensitivity to touch, temperature, and even clothing.

• Systemic Effects: High-potency TSW can sometimes trigger fatigue, insomnia, mood swings, and even flu-like symptoms.

Medium Potency Steroids: Class 4, 5

Medium-potency steroids like triamcinolone acetonide (Kenalog) or fluocinonide (Lidex) may cause a less intense withdrawal compared to their high-potency counterparts. However, the discomfort is still significant:

• Moderate Redness and Itching: While not as fiery as high-potency TSW, the redness and itching can still be bothersome and persistent.

• Dryness and Flaking: The skin may become dry, flaky, and rough, leading to discomfort and a compromised skin barrier.

• Hair Loss: In some cases, TSW from medium-potency steroids can trigger temporary hair loss.

• Mood Changes and Sleep Disturbances: These symptoms can manifest, though they are generally less severe than in high-potency withdrawal.

Low Potency Steroids: Class 6, 7

Low-potency steroids like hydrocortisone or desonide (Desowen) are considered the safest. However, even these mild formulations can cause withdrawal symptoms in some individuals, especially if used for extended periods:

• Mild Redness and Itching: The skin may appear slightly red and itchy, but the discomfort is usually manageable.

• Dryness and Sensitivity: The skin may feel dry, tight, and sensitive to touch.

• Minor Flaking: Some individuals may experience mild flaking or peeling.

Additional Factors Influencing TSW

TSW severity is influenced by various factors beyond potency, including frequency, amount, and duration of use, individual skin sensitivity, and underlying health conditions. Notably, even topical immunosuppressants like Tacrolimus can trigger withdrawal reactions similar to high-potency steroids.

Understanding Skin's Response to Steroids

To comprehend how steroids impact our skin, we must first understand its natural defense mechanism. When exposed to irritants, the skin reacts with inflammation (redness, swelling, heat), followed by proliferation (flaking, itching) to heal and protect the affected area.

Steroids offer temporary relief by suppressing this natural immune response. However, prolonged use weakens the skin's ability to function and repair itself, leading to hypersensitivity and slow healing. Paradoxically, the intense flaking and discomfort often seen during steroid withdrawal are signs that the skin is working to recover.

Identifying and eliminating the initial trigger is crucial for long-term healing, though this can be challenging. While steroids offer a tempting quick fix, understanding their potential long-term impact on the skin is essential for making informed decisions about treatment.

A Personal Experience

During my daughter's consultation with Dr. Jay at Skin Health, we discussed her extensive history of topical steroid use, including various potencies from mildest to the strongest since age three. Despite the potential for a long and challenging withdrawal, Dr. Jay reassured us that her young age would aid her recovery.

Understanding the complex relationship between topical steroids and your skin can be empowering in your healing journey. Remember, the discomfort you're experiencing is not a setback, but rather your body's way of reclaiming its natural balance. With patience, self-compassion, and proper support, you can emerge from this experience with healthier, stronger skin. This journey is not in vain; it's a path towards resilience and renewed well-being.
