How they work
Take your medicine as instructed by your doctor. They'll explain how much to take and how often.
It's normally best to take steroid tablets with or soon after a meal – usually breakfast – because this can stop them irritating your stomach.
If you forget a dose, take it as soon as you remember. If it's almost time for your next dose, skip the one you missed.
Don't take a double dose to make up for a forgotten one.
Accidentally taking too many steroid tablets is unlikely to be harmful if it's a one-off. Speak to your doctor or a pharmacist if you're worried.
Taking too many steroid tablets over a long period can make you more likely to get side effects.
Don't stop taking your medicine without talking to your doctor.
If you've been taking steroid tablets for more than a few days, you usually need to reduce your dose gradually.
This can help avoid unpleasant side effects (withdrawal symptoms) – such as severe tiredness, joint pain , vomiting and dizziness – and stop your original symptoms coming back suddenly.
Taking steroid tablets for less than three weeks is unlikely to cause any significant side effects. But you may get some side effects if you need to take them for longer or at a high dose.
Side effects of steroid tablets can include:
Most side effects will pass once treatment stops. Tell your doctor if they bother you.
You can report any suspected side effect to a UK safety scheme.
The following tips may help reduce the side effects of steroid tablets:
Your doctor may reduce your dose or suggest taking your tablets less often (for example, every other day) if you're having side effects.
They may also sometimes recommend other medicines to take alongside steroids to protect you from some of the side effects, such as medicines to help prevent indigestion or heartburn.
You may be given a special steroid treatment card that explains how you can reduce the risk of side effects.
Some medicines interfere with the way steroid tablets work. Tell your doctor if you take any other medicines, including herbal remedies and supplements, before starting steroid tablets.
If you're already taking steroid tablets, ask your doctor or a pharmacist for advice before taking any other medicines, remedies or supplements.
You can usually drink alcohol while taking steroid tablets, but don't drink too much as this may irritate your stomach.
You can also eat most foods while taking steroid tablets. Don't eat liquorice while taking prednisolone, however, as this can increase the amount of the medicine in your body.
Most people can take steroid tablets.
Tell your doctor before starting treatment if you:
Steroid tablets may not be suitable in these cases, although your doctor may recommend them if they think the benefits outweigh any risks.
Steroids are a man-made version of hormones normally produced by the adrenal glands, two small glands found above the kidneys.
When taken in doses higher than the amount your body normally produces, steroids reduce redness and swelling (inflammation). This can help with inflammatory conditions such as asthma and eczema.
Steroids also reduce the activity of the immune system, the body's natural defence against illness and infection.
This can help treat autoimmune conditions, such as rheumatoid arthritis or lupus , which are caused by the immune system mistakenly attacking the body.
Steroid tablets are different from the anabolic steroids used by athletes and body builders to improve their performance.
