Steroid tablets

Steroid tablets (also called corticosteroid tablets) are a type of anti-inflammatory medicine.

Steroid tablets are different from anabolic steroids.

Anabolic steroids are sometimes prescribed by healthcare professionals. They can also be misused by people to increase muscle mass and improve athletic performance.

Read the patient information leaflet that came with the steroids you were prescribed. It will have specific advice about your medication.

Types of steroid tablets

Steroid tablets are only available on prescription.

Dissolvable, liquid and syrup versions are also available.

Examples include:

  • prednisolone
  • betamethasone
  • dexamethasone

Uses of steroid tablets

Steroid tablets are used treat problems such as:

  • allergies
  • asthma
  • eczema
  • inflammatory bowel disease
  • arthritis

Get emergency help

Urgent advice: Go to your nearest emergency department (ED) or phone your GP if you get:

  • a rash
  • swelling of the mouth or face
  • difficulty breathing

These are signs of an allergic reaction. Stop taking your steroid tablets.

Check if you can take steroid tablets

Most people can take steroid tablets.

Do not take steroid tablets if you have:

    • had an allergic reaction to steroids in the past
    • any infections
    • recently had, or are about to have a vaccination

Check with your GP if you have:

    • diabetes
    • severe depression, manic depression or a family history of these illnesses
    • epilepsy
    • high blood pressure
    • problems with your liver, heart or kidneys

Tell your GP about risks of infections

You are more likely to get infections when you're taking steroid medication.

Tell your GP if you're exposed to infectious illnesses like chickenpox or shingles.

Steroids makes you more likely to catch infections such as:

Tuberculosis (TB) may also recur.

Keep away from people with an infectious disease, especially chickenpox or shingles. If you have never had these illnesses, they could make you very ill.

Food and alcohol

You can usually drink alcohol while taking steroid tablets. Don't drink too much as this may irritate your stomach.

You can eat most foods while taking steroid tablets. Do not eat liquorice while taking prednisolone. This can increase the amount of the medicine in your body.

How and when to take steroid tablets

Your GP, pharmacist or nurse will explain how much to take and how often.

It's best to take steroid tablets in the morning with breakfast.

This is to try and lower the risk of the medication disturbing your sleep. Taking it with a meal can also prevent stomach irritation.

If you miss a dose

Take your missed dose as soon as you remember, unless it's nearly time for the next one. In this case, skip the missed dose and take your next one as normal.

Do not take a double dose to make up for a forgotten one.

If you often forget doses, it may help to set a reminder alarm.

If you take too much

Talk to your GP or a pharmacist if you're worried you've taken too many tablets.

Taking too many steroid tablets over a long period can make you more likely to get side effects and may affect your hormones. In children, this may affect growth and development.

Coming off treatment

Do not stop taking your medicine without talking to your GP first.

If you've been taking steroid tablets for more than a few days, you will need to reduce your dose gradually. Your GP will tell you how to do this.

This can help avoid unpleasant withdrawal symptoms such as:

  • severe tiredness
  • joint pain
  • vomiting
  • dizziness
  • losing your appetite
  • mood changes
  • difficulty sleeping
