Mometasone for severe inflammatory skin conditions

About mometasone

Mometasone is classed as a strong topical corticosteroid. Topical corticosteroids are also referred to as topical steroids. Topical steroids are used in addition to moisturisers (emollients) for treating inflammatory skin conditions such as eczema and dermatitis. A topical steroid is used when patches of eczema or dermatitis flare up. Mometasone relieves the symptoms of a flare-up by reducing inflammation, itching and redness. It is not a cure for the condition, but it will help to relieve the symptoms. Short courses of mometasone may also be prescribed for the treatment of psoriasis for small areas such as the scalp, soles of the feet, or palms of the hands.

Mometasone is available in a number of different preparations. It is likely you will be prescribed a cream if the affected areas of your skin are moist or weeping, or an ointment if your skin is dry. It is also available as an application for the scalp. Mometasone is not generally suitable for children, although short courses of up to two weeks may occasionally be prescribed for a child by a skin specialist doctor.

Before using mometasone

To make sure this is the right treatment for you, before you start using mometasone it is important that your doctor knows:

• If you have any areas of infected skin.

• If you have rosacea or acne.

• If you are pregnant or breastfeeding.

• If you have ever had an allergic reaction to a skin preparation.

How to use mometasone

• Before you start using the preparation, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about topical steroids and will provide you with a full list of the side-effects that you may experience from using them.

• Apply a small amount to the areas of skin which are inflamed, once a day. Then gently rub it into the skin until it has disappeared. If you are using a scalp application, apply a few drops to your hair and rub it in gently. You can apply it to either dry or wet hair. Do not use mometasone on any open sores or any infected areas of skin.

• The amount of topical steroid that you should apply is commonly measured by fingertip units (FTUs). One FTU is the amount of cream or ointment that is squeezed out along an adult's fingertip (that is, from the very end of the finger to the first crease in the finger). As a guide, one FTU is enough to cover an area twice the size of an adult hand. Your doctor will give you an idea of how many FTUs you will need to cover the area of your skin which is affected.

• If you are using more than one topical corticosteroid, make sure you know when and where to use each one. If you are unsure, check with your doctor or ask your pharmacist for further advice.

• After you have applied mometasone, remember to wash your hands (unless your hands are the treated area).

• If you are using mometasone for psoriasis, make sure you follow your doctor's instructions carefully. It should not be used for large areas of psoriasis or for long periods of time, as these can cause your symptoms to flare up again afterwards.

Getting the most from your treatment

• If you are using a moisturiser along with this preparation, apply the moisturiser first. Then wait 10-15 minutes before applying mometasone. This allows time for the moisturiser to be absorbed before the topical corticosteroid is applied. Your skin should be moist but not slippery when you apply mometasone.

• Do not use mometasone on your face unless a skin specialist doctor has said you should. If you have been told to use it on your face, be careful not to get any preparation near your eyes and do not use it for longer periods of time than you have been advised.

• Unless advised to do so by your doctor, do not apply a bandage or dressing to the area being treated, as this will increase absorption of the preparation and increase the risk of side-effects.

• Continue to use mometasone until the flare-up has gone, and then stop it. A course of treatment for 7 days is often sufficient. If your symptoms have not improved after this time (or if they get worse), speak again with your doctor for further advice. Topical corticosteroids like mometasone should not be used for long periods of time or on large areas of the body.

• After you finish using mometasone, continue to use your moisturiser every day. This will help to prevent a further flare-up. Your doctor may also prescribe a less potent steroid cream for you to use when needed.

Can mometasone cause problems?

Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them. You can reduce the risk of side-effects from mometasone, by applying the preparation thinly, no more than once a day, and to the affected areas only.

If you experience any other symptoms which you think may be due to mometasone, speak with your doctor or pharmacist for further advice.

How to store mometasone

• Keep all medicines out of the reach and sight of children.
