What are topical corticosteroids?

Topical corticosteroids are steroid medications that are applied directly to the skin to reduce inflammation and irritation.

Topical corticosteroids come in several different forms, including:

  • Cream
  • lotion
  • gel
  • moss
  • ointment
  • Tapes and bandages
  • solution

They are available in 4 different potency strengths:

  • slight
  • ease
  • powerful
  • very effective

Conditions treated with topical corticosteroids

Topical corticosteroid therapy is indicated in conditions characterized by inflammation, hyperproliferation, and immunologic involvement. They can also relieve the symptoms of burning and itching lesions.

Conditions widely treated with topical corticosteroids include:

  • Eczema – such as atopic eczema
  • Contact dermatitis - causes things like dandruff and scaly patches on the skin
  • psoriasis

Topical corticosteroids do not cure these conditions, but they can help relieve symptoms.

Side effects of topical corticosteroids

Topical corticosteroids rarely cause serious side effects if used correctly.

The most common side effect of topical corticosteroids is a burning or stinging sensation when taking the medication. However, this usually improves as your skin adjusts to the treatment.

Less common side effects may include:

  • You have an existing skin infection that worsens or spreads
  • Inflammation of hair follicles (folliculitis)
  • Thinning of the skin, which can make the affected skin more susceptible to damage; for example, you may bruise more easily
  • Stretch marks, which may be permanent, although they may become less noticeable over time
  • Contact dermatitis, a skin irritation caused by a mild allergic reaction to substances in certain topical corticosteroids
  • Acne, or worsening of acne
  • Rosacea, a condition that causes redness and flushing of the face
  • Changes in skin color – this is often more noticeable in people with darker skin
  • Excessive hair growth in the area of ​​skin being treated

You are more likely to experience side effects if you:

  • Use more potent corticosteroids
  • Use for long periods of time or large areas

Older adults and young children are more susceptible to side effects.

If strong or very potent topical corticosteroids are used for long periods of time or over large areas, there is a risk that the drug will be absorbed into the bloodstream and cause internal side effects, such as:

  • Children's growth rate slows down
  • Cushing's syndrome

This is not a complete list of all possible side effects. For more information about side effects, see the leaflet that comes with the medicine.

Withdrawal side effects

Withdrawal reactions may occur if topical corticosteroids are discontinued after long-term continuous use (usually more than 12 months in adults). These can sometimes be serious. Your doctor may recommend stopping treatment gradually to avoid this.

Withdrawal side effects can include:

  • Redness or color changes in the skin (may be less noticeable on brown or black skin)
  • Skin burning, stinging, itching, or peeling, or oozing, open sores
  • A skin condition you are treating suddenly worsens

If you use topical corticosteroids long-term, it's a good idea to have your treatment reviewed by your doctor.

Preparation

Corticosteroid ointments provide more occlusion and lubrication than other preparations. This preparation increases the absorption of steroids.

Corticosteroid creams contain water suspended in oil. Creams are usually less effective than ointments.

Gels, lotions, and gels are minimally occlusive.

Shampoos, foams and mousses are effective treatments for your scalp.

World Health Organization classification of topical corticosteroids

The effectiveness of topical corticosteroids depends on the formulation, specific molecule type, extent of skin absorption, and amount reaching target cells. Efficacy is also increased when the formulation is used under an occlusive dressing or over an intergrated area. Generally speaking, ointments are more effective than creams or lotions.

成年後懷疑自己有注意力不足過動症(ADHD),應該接受診斷嗎?

在過去,注意力不足過動症(Attention-Deficit/Hyperactivity Disorder, ADHD)多被視為「小孩的病」,很多成年人小時候從未被評估或診斷。直到近年社會對心理健康重視度提升,許多成人才開始懷疑,自己長期以來的專注困難、健忘、衝動或時間管理不良,可能與 ADHD 有關。這種「晚發現」的情況相當普遍,也引發了問題:成年後是否值得接受 ADHD 診斷?

電擊槍的機制與對人體健康影響

電擊槍的機制與對人體健康影響

在現代執法中,警察常使用所謂「非致命性武器」(less-lethal weapons),其中最廣為人知的便是 電擊槍(Taser)。電擊槍的設計初衷是提供一種介於徒手制服與槍械之間的選擇,藉由暫時性電擊使嫌疑人失去行動能力,以降低致命暴力發生的風險。然而,電擊槍並非完全無害,背後涉及的電流機制與人體生理反應值得深入探討。
