1. What Betnesol is and what it is used for
Betnesol 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 corticosteroids (such as Betnesol) is an effective way to treat various illnesses involving
inflammation in the body. Betnesol reduce this inflammation, which could otherwise go on making your
condition worse. You must take this medicine regularly to get maximum benefit from it.
Many different conditions can be improved by the use of corticosteroids, as they reduce inflammation
(redness, tenderness, heat and swelling) in the body.
Betnesol is used to treat:
 asthma;
 severe allergic reactions;
 rheumatoid arthritis;
 autoimmune diseases such as systemic lupus erythematosus (SLE) and polyarteritis nodosa;

nephrotic syndrome), bowels (such as ulcerative colitis and Crohn’s disease) and heart;

Mental problems while taking Betnesol
Mental health problems can happen while taking steroids like Betnesol (see also section 4).
 These illnesses can be serious
 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 who is 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.
Chickenpox, shingles or measles
You should avoid contact with anyone who has either chickenpox, shingles or measles as it could be
extremely serious if you caught it from them.
Tell your doctor immediately if you suspect you may have come into contact with a person who has
chickenpox, shingles or measles. However, do not stop taking your tablets, unless your doctor tells you to.
Pregnancy and breast-feeding
If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your
doctor or pharmacist for advice before taking this medicine.
Taking steroids often or for a long time during pregnancy can slow the baby’s growth in the womb or may
temporarily affect the baby’s heart and body movements.
Sometimes the baby may get digestive juices going up into the tube that carries food from the mouth to the
stomach. The baby may also make less of its own steroid after birth, but this rarely causes any problems. If
you become pregnant whilst taking this medicine, please tell your doctor but DO NOT stop taking the
tablets unless told to do so (see section 3).
If you are breast-feeding, the steroid may enter the baby and lower their hormone levels, if you are taking
high doses for a long time.
Betnesol contains Sodium
This medicinal product contains 20.9mg sodium per tablet. To be taken into consideration by patients on a
controlled sodium diet. Tell your doctor or pharmacist before taking Betnesol if this applies to you.
