1. What Betamethasone Injection is and what it is used for

Betamethasone Injection belongs 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 Betamethasone Injection) is an effective way to treat various illnesses involving inflammation in the body. Betamethasone 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.

Betamethasone 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
  • to treat severe shock, (collapse) due to surgery, injury or overwhelming infection.

Corticosteroids are also used to help prevent organ transplant rejection following organ transplant surgery.

2. What you need to know before you are given Betamethasone Injection

Do not use Betamethasone Injection:

  • if you are allergic to betamethasone or any of the other ingredients of this medicine (listed in section 6).
  • if you have an infection and have not yet started taking any medicine (e.g. antibiotics) to treat it.

Mental problems while using Betamethasone Injection

Mental health problems can happen while using steroids like Betamethasone Injection (see 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 occur they may need treatment.

Talk to a doctor if you (or someone who is using this medicine), shows 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 any of these 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 using this medicine, 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 for advice before using this medicine.


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.

Betamethasone Injection contains sodium metabisulphite and sodium

Betamethasone Injection contains sodium metabisulphite (0.1% w/v) as a preservative, it may rarely cause severe hypersensitivity reactions and bronchospasm. This medicinal product contains less than 1 mmol sodium (23 mg) per 1ml, i.e. essentially ‘sodium- free’. Tell your doctor or nurse before you are given Betamethasone Injection if this applies to you.

3. How you will be given Betamethasone Injection

Always use this medicine exactly as your doctor has told you. Check with your doctor if you are not sure.

Important: Your doctor will choose the dose that is right for you.

You may have been given a steroid card which also tells you how many injections you need each day (see section 6).

The dose used will depend upon the disease, its severity and how quickly you get better. Betamethasone Injection is not intended for long term use. The following are for guidance only:

The recommended doses are:

Local injections (excluding eye):

Adults: 4 – 8mg (1 – 2ml), repeated up to three times.

Method of administration:

Betamethasone Injection can be given slowly into a vein, deep into a muscle or locally at the site of inflammation. It should not be injected directly into tendons. Your doctor will decide where, how much and how often you should be given Betamethasone Injection.

If you are given more Betamethasone Injection than you should

If you think you have been given too much of the injection, immediately tell your doctor or nurse. The dose may be reduced slowly over time to minimise any effects.

If you forget to use Betamethasone Injection

If you forget to have a dose, i.e. miss your doctor’s appointment, see your doctor as soon as possible.

If you stop using Betamethasone Injection

Do not stop using Betamethasone Injection without first talking to your doctor.

It is very important that you do not suddenly stop using Betamethasone Injection, even if you feel better from your original illness or are suffering from a side effect, unless your doctor tells you to. If you stop using your medicine too suddenly, you may suffer from some of the following; fever, joint and muscle pain, itchy eyes, nose or skin, mood changes, loss of weight, low hormone levels or low blood pressure (symptoms of which may include dizziness, headaches or fainting). In extreme cases this can be fatal. Your doctor will tell you how to stop using Betamethasone Injection.

If you have any further questions on the use of this medicine, ask your doctor or nurse.
