1. Why am I using DEXMETHSONE?
DEXMETHSONE contains the active ingredient dexamethasone. DEXMETHSONE belongs to a group of medicines called corticosteroids which are a synthetic version of a naturally occurring body hormone called cortisol.
DEXMETHSONE is used in the treatment of many different conditions including severe allergies, severe or chronic asthma, skin problems, arthritis, inflammatory diseases of the bowel, some types of cancer and “auto-immune” diseases.
It is also used to prevent or reduce the symptoms of inflammation (such as swelling, redness, pain, tenderness or itching) in any part of the body. These symptoms can occur in response to injury or can be caused by many different conditions.
DEXMETHSONE works by acting on the immune system and blocking the production of substances that trigger allergic and inflammatory actions.
Ask your doctor if you have any questions about why DEXMETHSONE has been prescribed for you.
Your doctor may have prescribed it for another reason.

4. How do I use DEXMETHSONE?
How much to take
The dose will depend on the condition being treated and your response to the treatment. Your initial dose will be maintained or adjusted until a satisfactory response is noted.
Your doctor will tell you how many tablets you will need to take each day.
When to take it
How often you take DEXMETHSONE depends on what condition is being treated.
Do not miss any doses even if you feel better.
Missing doses may make your symptoms worse.
How long to take it
Continue taking your medicine for as long as your doctor tells you.
Some people will need to take DEXMETHSONE for short periods of time, whereas other people may require long term therapy.
If you have been taking it for a long time, your doctor may gradually reduce the amount you are taking over a period of several days, weeks or months before stopping completely.
If you have been taking it for a short period of time, this may not apply.
If you forget to use DEXMETHSONE
If you miss a dose of this medicine, the decision of whether you should take it or not will depend on how many times a day your doctor has told you to take DEXMETHSONE.
If you are taking DEXMETHSONE:
*once a day –
Take the missed dose as soon as possible, then go back to your regular dosing schedule. If you do not remember until the next day, skip the missed dose and do not double the next one.
*several times a day –
Take the missed dose as soon as possible, then go back to your regular dosing schedule.
*on alternate days –
If you miss a dose and remember it the same morning, take it straight away, then continue as you normally would. If you do not remember the missed dose until later in the day, wait and take it the following morning. Then skip a day before continuing your regular dosage schedule.
Do not take a double dose to make up for any missed dose.
This may increase the chance of you getting an unwanted side effect.
If you are not sure what to do, ask your doctor or pharmacist.
If you use too much DEXMETHSONE
If you think that you have used too much DEXMETHSONE, you may need urgent medical attention.

5. What should I know while using DEXMETHSONE?
Things you should do
Take DEXMETHSONE exactly as directed by your doctor.
If you do not follow your doctor’s instructions, you may not get improvement in the symptoms of your condition. Try not to miss any doses and take the medicine even if you feel well.
Ask your doctor when and how you should stop taking DEXMETHSONE.
If you have been taking it for a long time, your doctor may gradually reduce the amount you are taking over a period of several days, weeks or months before stopping completely.
If you have been taking it for a short period of time, this may not apply.
Keep all of your doctor’s appointments.
If you are taking DEXMETHSONE for a long period of time, you must have regular checkups with your doctor. This is especially important for children who are taking DEXMETHSONE.
Tell your doctor if you get a serious infection or injury whilst taking DEXMETHSONE.
Tell any other doctors, dentists, and pharmacists who are treating you that you are taking DEXMETHSONE, especially if you are being started on any new medicines.
If you plan to have surgery that needs a general anaesthetic, tell your doctor, surgeon or dentist that you are taking DEXMETHSONE.
The trauma of the operation or surgery may mean that your dose of this medicine needs to be adjusted to cover this stressful time.
Tell your doctor immediately if you are diabetic and if you notice any change in your blood or urine sugar readings.
DEXMETHSONE may affect your blood sugar levels as it can affect the body’s ability to handle glucose. For diabetics, this means that your diabetes may become more severe.
For others, diabetes may develop for the first time while taking corticosteroids such as DEXMETHSONE.
Tell your doctor if you become pregnant while taking DEXMETHSONE.
Things you should not do
- Do not stop using this medicine suddenly or lower the dosage without checking with your doctor.
If you stop taking it suddenly, the symptoms of your condition may return or you may develop symptoms of certain hormone deficiencies such as fainting, weakness, restless-ness, nausea, vomiting, headache, dizziness, muscle weakness or joint pain. - Do not have any immunisations while you are taking DEXMETHSONE.
Immunisation with ‘live’ vaccines may interfere with DEXMETHSONE or not work at all.
Things to be careful of
- Avoid close contact with anyone who has a contagious disease such as chicken pox or measles.
- Tell your doctor immediately if you think you have been exposed to chickenpox or measles.
Exposure to such diseases while you are taking DEXMETHSONE can put you at greater risk of developing these diseases if you have not had them before.
Driving or using machines
Be careful before you drive or use any machines or tools until you know how DEXMETHSONE affects you.
Infections
You should see your doctor for medical advice for any but the most minor infections.
The signs and symptoms of infections such as fever or inflammation may be hidden by the anti-inflammatory action of DEXMETHSONE.
Looking after your medicine
