General precautions regarding steroid use in specific diseases, masking infection, concomitant medicines etc. in line with current recommendations.

Treatment with corticosteroid may reduce your body’s ability to fight infection. This can sometimes lead to infections caused by germs that rarely cause infection under normal circumstances (called opportunistic infections). If you get an infection of any kind during treatment with this medicine, contact your doctor immediately. This is particularly important if you notice signs of pneumonia: cough, fever, shortness of breath and chest pain. You may also feel confused, particularly if you are elderly. You should also tell your doctor if you have had tuberculosis or if you have stayed in regions where roundworm infections are common.

It is important that whilst you are taking this medicine you avoid contact with anybody who has chickenpox, shingles or measles. If you think you may have had exposure to any of these diseases, you should consult your doctor immediately. You should also inform your doctor if you have ever had infectious diseases such as measles or chickenpox and of any vaccinations.

Treatment with this medicine may cause central serous chorioretinopathy, an eye disease that leads to blurred or distorted vision. This happens usually in one of the eyes. If you notice blurring or distorted vision that lasts for several days, please contact your doctor.

Treatment with this medicine may cause tendon inflammation. In extremely rare cases, a tendon may rupture. This risk is increased by treatment with certain antibiotics and by kidney problems. Contact your doctor if you notice painful, stiff or swollen joints or tendons.

Treatment with Dexamethasone can cause a condition called adrenocortical insufficiency. This can cause change in effectiveness of the medicine following stress and trauma, surgery, childbirth or illness and your body may not be able to respond in the usual way to severe stress such as accidents, surgery, childbirth or illness.

If you have an accident, are ill, have other specific physical stress conditions, or require any surgery (even at the dentists) or you require a vaccination (particularly with ‘live virus’ vaccines) whilst taking or when you have finished taking Dexamethasone, you should inform the person treating you that you are taking or have taken steroids.

If you have suppression tests (test for the amount of hormone in the body), skin test for allergy or test for bacterial infection you should inform the person performing the test that you are taking dexamethasone as it may interfere with the results.

You may also find that your doctor will reduce the amount of salt in your diet and give you a potassium supplement whilst you are taking this medicine.

If you are elderly, some of the side effects of this medicine may be more serious, especially thinning of the bones (osteoporosis), high blood pressure, low potassium levels, diabetes, susceptibility to infection and thinning of the skin. Your doctor will monitor you more closely.

If a child is taking this medicine, it is important that the doctor monitors their growth and development at frequent intervals.
