Aristocort cream and ointment

Also called triamcinolone acetonide cream or ointment

Key points about Aristocort®

  • Aristocort cream or ointment contains a moderately potent steroid.
  • It’s used to reduce inflammation and itchiness caused from skin conditions such as severe eczema that hasn't responded to other treatments or psoriasis.
  • Find out how to use it and possible side effects.

 

Psoriasis on arm

Aristocort® belongs to a group of medicines known as topical steroids.

It contains triamcinolone acetonide, a moderately potent steroid that helps to relieve inflammation and itching.

It’s used for skin conditions such as severe eczema or dermatitis that haven't responded to other treatments, and psoriasis.

The cream is usually best for treating moist areas of skin, as creams absorb into the skin well.

The ointment tends to be greasy and is usually best for treating areas of skin that are dry or thickened. Ointments have the lowest chance of burning and stinging when applied. 

In Aotearoa New Zealand, Aristocort cream and ointment both contain 0.02% of triamcinolone acetonide and are available on a prescription written by a prescriber

Use topical steroids as advised by your healthcare provider. They will explain where, how often and for how long to apply the medicine.

  • Wash your hands before and after applying (unless treating your hands).
  • Don’t use on broken, infected or weeping skin unless advised.
  • Don’t use near your eyes, mouth or genitals unless directed.
  • If using a moisturiser, apply the moisturiser 10 minutes before applying Aristocort.
  • Creams or ointments are rubbed gently into the affected skin until they have disappeared.
  • The amount of topical steroid you should apply is measured in fingertip units (FTUs). One FTU is the amount of topical steroid that's squeezed out from the tube along an adult's fingertip (the distance from the tip of the adult index finger to the first crease) as shown in the image below.

  • 1 FTU is enough cream or ointment to cover an area the same size as 2 adult handprints (palms and fingers).
  • You'll need to use enough topical steroid to get a response, then you can use a less potent product to control the condition.
  • If you don't get a response after 7 days, instead of using it more often or using it for a long time, talk to your healthcare provider. 
  • Your healthcare provider may ask you to cover treated areas. Covering the treated area after applying a topical steroid increases the absorption of the steroid but may also increase side effects. 
  • If you have frequent skin flare-ups you may be advised by your healthcare provider to use topical steroid treatment for a short time, to prevent flare-ups. This is also called ‘pulse dosing’ or ‘weekend treatment’ where you apply the topical steroid for 2 days a week during remission (between flares).

The diagram below gives some guidance on how many fingertip units of steroid cream are required for adults.

Soak and smear method

If your topical steroid isn’t helping your skin condition, or if your symptoms are severe, you can try a method called ‘soak and smear’. Here is some guidance on how to do it:

  • Have a lukewarm bath about 20 minutes before you go to bed. Gently pat your skin dry so it stays slightly damp.
  • Smear a generous amount of topical steroid onto the affected areas.
  • Wear loose-fitting clothes.
  • In the morning, moisturise your skin.

     

If you find you need to use topical steroids every day for more than 2 weeks, or more than 3 times a week for most weeks, talk to your healthcare provider.

Like all medicines, Aristocort cream and ointment can cause side effects, although not everyone gets them. If you're worried about any symptoms, talk to your healthcare provider. The following information offers some guidance but doesn't include all possible side effects.


Tell your healthcare provider if these side effects bother you

  • Burning or stinging feeling: Talk to your healthcare provider if it's uncomfortable.
  • Thinning of the skin: It can happen if a covering is used after treatment or if topical steroids are used often on a large area or long-term. It's less likely to occur with a short course. If it does happen, it often goes away when the treatment is stopped.
  • Permanent stretch marks, bruising, discolouration, thin spidery veins: These aren't common and may occur with long-term use of topical steroids.
