Steroid injections can be a quick and effective treatment for your soft tissue problems,joint pain, and inflammation, although the improvement is usually temporary. They’re normally given as part of a wider rehabilitation programme. You can discuss the benefits and risks of steroid injections with Your GP, Nurse Physiotherapist or Dr Vitarana before you start treatment, so you’re able to make an informed decision.
What are steroid injections and how are
Some steroids occur naturally in the human body. Artificial steroids act like natural steroids to reduce inflammation. They’re not the same as anabolic steroids used by bodybuilders to increase their muscle size and strength.
Steroid treatment for arthritis and related conditions can be taken as tablets or given as injections into the affected area.
Steroid injections are often recommended for people with
rheumatoid arthritis and other types of inflammatory arthritis. They may also be recommended for osteoarthritis if your joints are very painful or if you need extra pain relief for a time. The injection can reduce inflammation, which in turn should reduce pain.
Steroid injections can’t treat the underlying cause of your condition, but they can treat the symptoms. Several different steroids are available for injection.
Common examples of steroid injections are:
• triamcinolone (try-am-sin-o-lone)
Steroid injections take around a week to become effective,but can ease your symptoms for two months or longer. These are described as less soluble, because the drug takes longer to get into
your system. How quick the treatment works, and how long it lasts will also depend on your condition. Steroid injections can be given to people of all ages, including children and teenagers.
How do I have steroid injections?
Dr Vitarana will talk to you about the most appropriate steroid mixture and dose for you. This will depend on your condition
and symptoms. Depending on where the pain and inflammation is, steroids can be injected:
• directly into an inflamed joint, this is known as an intra-articular
• into the soft tissue close to the joint, which is called a
• into a muscle, which is called an intramuscular injection.
Sometimes you’ll be given a local anaesthetic with the steroid to reduce the discomfort of the injection. This would mean your pain should be relieved within minutes. The effects of local anaesthetics
can wear off within half an hour, unless you’ve been given one that is long acting. You may have some numbness from the anaesthetic that could last up to 24 hours. Loose-fitting clothes may be more comfortable if you’re going for a steroid injection. You might be advised to wait for 10 to 15 minutes in the clinic after your steroid injection. If you do have any kind of reaction to the injection, it would be helpful to be around healthcare professionals. You may want to arrange transport home after the injection, especially if you’re going to have a local anaesthetic, because numbness from the anaesthetic can make it difficult to drive.
For some conditions, such as inflammatory types of arthritis, steroid
injections are often useful in the short term while you and your doctors find the right medications to control your arthritis in the long-term. In this case, once your arthritis is well controlled, the need for injections should be reduced.
Is there anything else I need to know
before I have a steroid injection?
You will not be able to have a steroid injection if you have an infection, particularly if it’s in the part of the body that needs treating.
There is evidence that having too many steroid injections into the same area can cause damage to the tissue inside the body. Dr Vitarana would recommend you don’t have more than three steroid injections into the same part of the body within a year. You may be advised to have less than that depending on your symptoms. If you have a condition called haemophilia which means your blood doesn’t clot properly, you’ll need to discuss this with your doctor, as you could be at an increased risk of bleeding into the joint
It’s important not to overdo it for the first two weeks after a steroid
injection. There is a small risk that if you exercise a joint too much
immediately after a steroid injection you could damage the tendon.
Tendons are strong cords that attach muscles to bones. After this time, it’s important to continue with any exercises given to you by your health professional. Start off gently and gradually increase the amount you do. If you’re having physiotherapy, your physiotherapist will help you find the right balance between rest and exercise.
Possible risks and side effects:
Most people have steroid injections without any side effects. They can be a little uncomfortable at the time of injection, but many people feel that this is not as bad as they feared.
Occasionally people notice a flare-up in their joint pain within the first 24 hours after an injection. This usually settles by itself within a couple of days, but taking simple painkillers like paracetamol will help. The risk of side effects is greatest with the stronger mixtures – methylprednisolone and triamcinolone.
Injections can occasionally cause some thinning or changes in the colour of the skin at the injection site, particularly with the stronger ones. Very rarely you may get an infection in the joint at the time of an injection. If your joint becomes more painful and hot you should see your doctor immediately, especially if you feel unwell.
People are often concerned about the possibility of other steroid related
side effects such as weight gain. One of the advantages of steroid injections compared to tablets is that often the dose can be kept low. This means that these other side effects are very rare unless injections are given frequently, more than a few times per year.
They can also cause changes in people’s mood – you may feel very high or very low. This may be more likely if you have a history of mood disturbance. If you’re worried please discuss this with Dr Vitarana.
Can I take other medicines along with
You can take other medicines with steroid injections. However, if
you’re taking a drug that thins the blood, known as an anticoagulant
(for example, warfarin), you may need an extra blood test to make sure that your blood is not too thin to have the injection. This is because of the risk of bleeding into the joint.
You should mention that you take anticoagulants to the person giving the injection. You may be advised to adjust your warfarin dose before having the steroid injection.
Steroid injections reduce the effect of your body’s immune system
in the short-term. This is how they reduce inflammation. Some vaccines work by giving you a very small dose of a particular disease, so that you then become immune to it. You won’t be
able to have a steroid injection close to the time you have certain vaccinations. Talk to your healthcare team about when you’ll be able to have a steroid injection if you’ve recently had a vaccination, or if
you’re due to have one soon.
There’s no reason to avoid alcohol after steroid injections. Government guidelines recommend that men and women shouldn’t regularly drink more than 14 units of alcohol a week. It’s a good idea to space your units out over the course of a week. Having at least
two alcohol-free days a week is good for your health.
Fertility, pregnancy and breastfeeding:
Current guidelines state that steroids are not harmful in pregnancy or breastfeeding. Single steroid injections shouldn’t affect fertility, pregnancy or breastfeeding and can be useful treatments in these situations. If, however, you’re pregnant or breastfeeding, you should discuss it with your doctor before having a steroid injection.
