Steroid creams, also called topical steroids or corticosteroids, can help treat psoriasis, but long-term use can cause side effects. Here’s what to know about using these creams safely.

Topical steroids are anti-inflammatory drugs you apply directly to your skin. These medications are one common treatment for psoriasis, an autoimmune condition that causes scaly patches, called plaques, on your skin.

Steroid creams can shrink these patches or even help them go away completely. However, these medications can cause side effects if you use them for a long time, so it’s important to follow any instructions your primary care doctor or dermatologist provides.

Below, get the details on different types of steroid creams, how they work, and precautions to take while using them.

If you have psoriasis, your immune system gets confused and starts attacking your skin. Antibodies flood the area to defend against the attack, and the surrounding tissue becomes inflamed. You may notice skin discoloration, swelling, pain, and tenderness.

Psoriasis also causes your skin to produce new cells more quickly than the old cells can fall off. This leads to the formation of plaques of thick, flaking skin.

When you apply a steroid cream, the steroids sink into the layers of your skin and enter various cells.

Topical steroids help treat psoriasis by telling your cells to:

  • stop making so many inflammatory chemicals
  • make more anti-inflammatory chemicals
  • slow down the growth of new skin cells

Because corticosteroids resemble the steroid hormones made by your adrenal glands, your cells accept their instructions as if they came from your body.

That said, you’ll need to keep applying the cream to replenish the medication in your skin. As the steroids hold off the psoriasis process, the patches should gradually shrink, allowing your skin to heal.

Topical steroids are organized into seven classes, with class 7 being the mildest and class 1 the strongest. Here are examples of creams you might find at each level:

  • Class 7 (mild): hydrocortisone (Synacort, Mycort-HC, Cortaid)
  • Class 6 (mild): desonide (Desowen)
  • Class 5 (medium): betamethasone valerate (Betaderm)
  • Class 4 (medium): mometasone furoate (Elocon)
  • Class 3 (strong): triamcinolone acetonide (Triderm)
  • Class 2 (strong): fluocinonide (Lidex)
  • Class 1 (ultra-strong): clobetasol propionate (Cormax, Temovate)

The Food and Drug Administration (FDA) has approved only the weakest steroid cream, hydrocortisone, as an over-the-counter (OTC) medication. You’ll need a prescription for all other topical steroids.

If you have plaques on sensitive areas, such as your face or groin, you’ll probably want to stick with the mild or medium steroid creams.

Stronger steroid creams are typically prescribed for chronic psoriasis that involves very thick plaques. While high level creams are more powerful, they also pose a higher risk of side effects. Healthcare professionals tend to reserve them for psoriasis plaques that don’t respond to gentler treatment.

Steroid creams can cause changes to your skin, such as:

Your risk of side effects goes up if you use steroid cream:

  • with a high potency
  • on large areas of skin
  • for longer than 3 weeks

Can topical steroids cause adrenal fatigue?

You may have read that chronic corticosteroid use can suppress the amount of natural steroid hormones your body produces and lead to adrenal fatigue, which can cause:

  • weakness
  • low blood pressure
  • lack of appetite

However, adrenal fatigue is mostly a concern with other forms of steroid medication, such as injections. That’s because injected or oral steroids have a higher rate of systemic absorption, which means they affect your whole body.

Even high potency steroid creams only rarely affect your adrenal glands. Topical steroids — those absorbed through your skin — have only a minimal effect on your body as a whole.

Each medication works a little differently, so it’s important to follow the label instructions for your specific cream. If you have a prescription medication, make sure to use it exactly as the prescribing doctor directed — and check with them if you have any questions.

Here are a few things to keep in mind when using steroid cream:

  • Apply regularly: Depending on the cream, you may need to apply it one to four times per day. Try to put it on at roughly the same time each day.
  • Start small: You need only enough cream to make a thin layer over the psoriasis plaque. Rub it in gently.
  • Only cover the plaques: Unaffected skin doesn’t need thinning as a thick plaque does, so avoid rubbing the cream into skin that’s not affected by psoriasis.
  • Wrap only if your doctor tells you to: Covering your psoriasis plaques with a bandage or cloth can help the cream soak in better. But it might also spread the cream to healthy skin, so you’ll want to check with your doctor before wrapping your skin.
  • Check with your doctor if you don’t notice an improvement: With most prescription steroid creams, you should notice some improvement in about a week — but if your symptoms don’t improve within about 2 weeks, you may want to check in with your doctor. If you’re using an OTC cream, it may take a little longer to notice the results.
FYI

If you’ve used a steroid cream for a long time and want to stop, your doctor may taper you off the medication. This means they’ll lower your dose gradually to prevent your psoriasis from flaring up in response to the sudden absence of medication.

Since steroid creams affect your immune system, they may not be the best option if you’re currently recovering from an infection or if you have an immunodeficiency disorder.

Your primary care doctor or another healthcare professional may also recommend nonsteroid psoriasis treatments if you have certain endocrine disorders, such as Cushing syndrome.

Other treatments for psoriasis include:

  • Vitamin D analogues: topical oils and ointments made of synthetic vitamin D
  • Tar soap: soap made from pine tree resins or coal byproducts
  • Salicylic acid: a chemical exfoliant found in OTC face washes and creams that can slough off dead skin cells
  • Methotrexate: a tablet or injection that suppresses your immune response
  • Cyclosporine: another immune suppressant you can take orally or as an injection
  • Retinoids: oral or topical medications made from vitamin A compounds
  • Biologics: medications made from living organisms that can block proteins that cause inflammation
  • Phototherapy: a skin treatment that uses controlled exposure to UV light
  • Laser therapy: lasers that target small areas of skin to destroy unhealthy cells

Your doctor may recommend combining steroid creams with other approaches to develop a treatment program that’s right for your specific psoriasis symptoms.

Below are some commonly asked questions about steroid creams for psoriasis.

What steroid cream is good for psoriasis?

Topical steroids come in various strengths, ranging from very potent to very weak. The best steroid cream for you will depend on the type and severity of your psoriasis and the area of skin affected.

How long does it take for steroid ointment to work on psoriasis?

It may take up to 6 weeks for a steroid ointment to have a noticeable effect on psoriasis.

What clears psoriasis fast?

The best treatment to clear psoriasis fast will depend on the type and severity of your psoriasis and the area of skin affected. Potential treatments include:

  • vitamin D analogues
  • tar soap
  • salicylic acid
  • methotrexate
  • cyclosporine
  • laser therapy

Steroid creams are one of the most common topical treatments for psoriasis.

While they can have powerful anti-inflammatory effects, they may also cause acne and skin discoloration or thinning if you use them for a long time.

Following your doctor’s directions when using steroid creams to treat psoriasis can help minimize your risk of side effects.
