1. What Dexamethasone Tablets are and what they are used for
Dexamethasone Tablets belong to a group of medicines called steroids. Their full name is corticosteroids. These corticosteroids occur naturally in the body, and help to maintain health and well-being.
Boosting your body with extra corticosteroid (such as dexamethasone) is an effective way to treat various illnesses involving inflammation in the body.
Dexamethasone tablets reduce this inflammation, which could otherwise go on making your condition worse. You must take this medicine regularly to get maximum benefit from it.
Ask your doctor to explain why you have been given Dexamethasone tablets if you are unsure.
2. What you need to know before you take Dexamethasone Tablets
Do not take Dexamethasone Tablets if you:
• are allergic (hypersensitive) to dexamethasone or any of the other ingredients of Dexamethasone Tablets.
• have an infection.
• are going to have any vaccinations - you must tell your doctor or nurse that you have been prescribed dexamethasone.
If you are not sure talk to your doctor or pharmacist before taking Dexamethasone.
Take special care with Dexamethasone Tablets
Check with your doctor first if:
• You have ever had severe depression or manic depression (bipolar disorder). This includes having had depression before or while taking steroid medicines like Dexamethasone.
• any of your close family has had these illnesses.
If either of these applies to you, talk to a doctor before taking Dexamethasone.
Check with your doctor before taking your medicine if:
• you have recently had a heart attack
• you have tuberculosis (TB) or X-ray changes, or have had it in the past
• you have a stomach ulcer or other digestive problem
• you have chickenpox, shingles, measles or any other infection including an eye infection
• you had muscle weakness after taking steroids in the past
• you have bowel problems such as ulcerative colitis
• you have epilepsy
Also, check with your doctor if any of the following problems run in your family, or if you have any of them:
• diabetes
• heart problems
• high blood pressure
• an eye condition called ‘glaucoma’
• kidney or liver problems
• a type of muscle weakening problem called ‘myasthenia gravis’
• thinning of the bones (osteoporosis)
• low thyroid levels (hypothyroidism).
If you are not sure if any of the above run in your family, or you have them, talk to your doctor or pharmacist before taking the tablets.
Important
If you are taking or have recently (within the last 3 months) been taking Dexamethasone and you become ill, suffer stress, get injured or are about to have surgery, tell your doctor or other healthcare professional.
If you have been on Dexamethasone for longer than 3 weeks and wish to stop taking it, do not stop suddenly.
Taking Dexamethasone for a long time increases your chance of getting infections and these might be worse than normal. Also, dexamethasone treatment can hide the usual symptoms of infection. Amoebic dysentery and an infestation of a gut worm (strongyloidiasis) may be activated or become worse, as may fungal and viral infections of the eye.
It is particularly important to avoid contact with people who have chicken pox, shingles or measles especially if you have not already had these illnesses or are not sure if you have had them. Go to your doctor immediately if you come in contact with measles. Dexamethasone increases the risk of a severe bout of chicken pox.
You should still take your Dexamethasone, but the dose may need adjusting. If you are about to take dexamethasone, or are already taking it, and you get a rash or other symptoms of an infection, tell your doctor immediately.
Mental Problems while taking Dexamethasone Tablets
Mental problems can happen while taking steroids like Dexamethasone (see also section 4 Possible Side Effects).

• Usually they start within a few days or weeks of starting the medicine.
• They are more likely to happen at high doses.
• Most of these problems go away if the dose is lowered or the medicine is stopped. However, if problems do happen they might need treatment.
Talk to a doctor if you (or someone taking this medicine), show any signs of mental problems. This is particularly important if you are depressed, or might be thinking about suicide. In a few cases, mental problems have happened when doses are being lowered or stopped.
Pay attention when using Dexamethasone:
Dexamethasone should not be used routinely in preterm neonates with respiratory problems.
