- They are also known as topical corticosteroids, glucocorticosteroids and cortisone.
- Topical steroids work by reducing inflammation and the amount of collagen in your skin, which may ease symptoms such as itchiness and redness.
- They are applied to your skin in the form of creams, ointments, lotions or solutions.
- For skin conditions associated with dryness, such as eczema, other treatments such as emollients and moisturisers may also be needed.
- If an emollient and a topical corticosteroid are prescribed at the same time, one should be applied at least 30 minutes before the other. The order of application is not important.

Steroid creams and ointments
Also known as topical steroids
Key points about topical steroids

- There are many types and brands of topical steroids available in New Zealand.
- Find out how to apply them safely and possible side effects.
There are many types and brands of topical steroids available in New Zealand.
- Topical steroids have varying potency and are generally grouped into four categories depending on their strength:
- moderately potent
- very potent.
- Your doctor will decide on the correct strength for you depending on your condition, age and the area of your body being treated.
- The stronger the product the more likely it is to cause side effects, so generally the mildest steroid that will work is used.
- Generally in adults, a strong product is used to get a problem area (other than the face) under control, then a moderate or mild product may be used to maintain that control.
- Topical steroids are absorbed at different rates from different parts of the body.
- A steroid that works on the face may not work on the palm, and a potent steroid used for the palm may cause side effects if applied to the face. There is much greater absorption where the skin is thin, for example, eyelids, genitals and skin creases, compared to thicker skinned areas, such as palms of your hands and soles of your feet.
|Very potent steroids
- Topical steroids are available in different formulations such as as creams, ointments, lotions, solutions or gels.
- Which one to use depends on the type of skin lesion, location on your body and potential for irritation (stinging) or allergy.
- Creams are usually best to treat moist or weeping areas of skin, and they rub into the skin well.
- Ointments tend to be greasy and are usually best to treat areas of skin that are dry or thickened. They have the lowest chance of burning and stinging with application.
- Lotions are easy to apply and may be useful to treat hairy areas such as the scalp.
- Topical steroids are usually only applied once or two times a day.
- Absorption of the steroid into the skin depends on the formulation in which the topical steroid is delivered. Higher absorption tends to occur with ointment or gel (thus increasing the potency of the product) compared to lower absorption products such as cream or lotion.
- Use topical steroids as instructed by your doctor, who will explain where, how frequently and for how long to apply the medication.
- Creams or ointments are rubbed gently into the affected skin until they have disappeared.
- The amount of topical steroid that you should apply is commonly measured by fingertip units (FTUs)
- One FTU is the amount of topical steroid that is squeezed out from a standard tube along an adult's fingertip (the distance from the tip of the adult index finger to the first crease). This should cover an area equivalent to your two palms (as shown in the image).
- View a useful video on FTUs in the resources column on this page. Read more about fingertip units(external link) .
- In some instances, your doctor may ask you to use plastic to cover treated areas. Covering the treated area with plastic after applying a topical steroid increases the absorption of the steroid, but may also increase side effects. Therefore it is usually recommended only in areas of very thick skin such as the palms of your hand and soles of your feet.
- Are you are taking or using any other medicines? This includes any other creams or medicated soaps you are using that are available to buy without a prescription.
- Have you ever had an allergic reaction to a medicine?
If so, it’s important that you tell your doctor or pharmacist before you start using topical steroids. Sometimes a medicine isn’t suitable for a person with certain conditions or it can only be used with extra care.
Like all medicines, topical steroids can cause side effects, although not everyone gets them.
