1. What Betnesol Injection is and what it is used for
Betnesol Injection belongs to a group of medicines called steroids. Their full name is
These corticosteroids occur naturally in the body and help to maintain health and well being.
Boosting your body with extra corticosteroids (such as Betnesol Injection) is an effective way
to treat various illnesses involving inflammation in the body. Betnesol Injection reduces this
inflammation, which could otherwise go on making your condition worse. You must use 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 Injection is used:
to treat asthma
to treat severe allergic reactions including reactions to drugs
to treat local inflammation e.g. of joints, tendons or the eye
as replacement for the body’s naturally occurring corticosteroid hormones when these are
reduced or absent

Most of these problems go away if the dose is lowered or the medicine is stopped.
However, if problems do occur they may need treatment.

problems. This is particularly important if you are depressed or might be thinking about

Pregnancy and breast-feeding

Taking steroids often or for a long period of 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 using this medicine, please tell
your doctor but DO NOT stop treatment 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 using high doses for a long period of time.
