Corticosteroid Injections

Introduction

Steroid injections, also known as corticosteroid injections, are anti-inflammatory drugs used to treat various conditions, including inflammatory bowel disease, sciatica, arthritis, and joint pain.

A dose of medication is administered directly to a problem area in your body using a corticosteroid, also known as a steroid injection. Inflammation can be lessened with the use of corticosteroids. Conditions like bursitis, tendonitis, and arthritis may benefit from injection therapy.

An injection of medication called a corticosteroid lowers swelling and decreases pain. They are also referred to as corticosteroid injections by medical professionals. Injecting a dosage of a corticosteroid into your body is the same treatment.

Corticosteroids, often known as steroids, are synthetic medications that closely mimic the hormone cortisol, which is produced by your adrenal glands. To lessen inflammation, they momentarily lower the activity of your immune system.

Corticosteroid injections are typically used by providers to address joint inflammation, including your:

• Shoulders.
• Spine.
• Hands.
• Hips.
• Knees.
• Feet.

Steroid Injections: What Are They?

Steroid injections, often known as corticosteroids, are injections of synthetic medications called corticosteroids that can reduce swelling and pain in particular body parts. Corticosteroids are similar to the hormone cortisol, which is produced by your adrenal glands. These are not the same as the hormone-related steroid compounds used by some athletes.

For the treatment of joint inflammation or other inflammatory diseases like lupus, rheumatoid arthritis, severe allergies, and asthma, your doctor can recommend a steroid injection. Among the several types of corticosteroids are corticosteroid, methylprednisolone, and prednisone.

Corticosteroid injections may also be used by your doctor to treat inflammation in your bursae or tendons, which are fluid-filled sacs that cushion the spaces between your bones, tendons, and joints. Only medical professionals provide steroid injections. Triamcinolone, methylprednisolone, and hydrocortisone are typical examples.

• Systemic steroids

Systemic steroids, which travel throughout your bloodstream to reach different locations, may be necessary when inflammation spreads throughout your body. Systemic steroids are necessary for conditions like lupus and systemic vasculitis, which is an inflammation of the blood vessels.

There are several ways to administer them:

• Intravenously
• Injected into a muscle
• Orally, via pills

• Local steroids

Injections of local steroids address certain inflammatory regions. For instance, a local steroid injection will be administered straight into the toe if you have painful arthritis in that area. To minimize therapeutic side effects, physicians prefer local steroids over systemic steroids whenever possible.

Types of corticosteroid

There are several types of corticosteroids, including:

• Inhalers, such as mouth or nasal sprays, lotions, gels, or creams (topical steroids), suppositories, which are placed into the rectum; tablets (oral steroids), the most potent form of steroid medication that affects the entire body; injections, which can be into blood vessels, joints, or muscles
• Certain kinds of steroids might not be appropriate for you if you have a persistent infection or certain medical conditions. You and your Doctor can discuss this.

Uses

Several types of steroids can be injected. Typical instances of steroid injections include:

• Hydrocortisone
• Triamcinolone
• Methylprednisolone.

The benefits of some steroid injections should persist for almost a week, with some beginning to reduce pain within hours. These short-acting soluble steroids may be referred to by your physician or another medical practitioner. When a medicine is soluble, it dissolves in your body and begins to act right away.

Other steroid injections can increase your symptoms for up to two months, but they take about a week to start working. Because it takes longer for the drug to enter your system, these are referred to as less soluble.

Your condition will also affect how quickly and how long the treatment lasts. People of all ages, including kids and teenagers with juvenile idiopathic arthritis (JIA), can receive steroid injections.

However, young patients should be given corticosteroid injections with caution. The shortest amount of time and the lowest effective dose should be administered. Children who receive too much steroid medication may experience growth problems.

Benefits

Corticosteroid injections provide safe and effective pain and inflammatory relief, but they are only temporary. As a result, you can engage in your regular daily tasks more effectively.

When you take steroids orally or intravenously, they enter your bloodstream and move throughout your body. That may be required in certain situations, such as when managing flare-ups of autoimmune disorders like multiple sclerosis that impact different body areas.

However, since steroid injections deliver the medication exactly where it needs to go, doctors prefer them whenever possible. Although the drug does reach your system, you probably won’t experience any negative side effects.

Cautions about corticosteroids

One of the many adverse effects of corticosteroids is high blood sugar. Therefore, before using any steroid medications, people with diabetes are encouraged to discuss their condition with their healthcare practitioners.

Due to additional negative effects, long-term usage of injectable corticosteroids is not advised. These include excessive blood pressure, stomach ulcers, delayed growth, osteoporosis, cataracts, and skin shrinkage and depigmentation. Short-term adverse effects include localized pain or infection at the injection site, which are possible. Typically, your doctor will only prescribe three or four corticosteroid injections annually.

Please talk about all the advantages and disadvantages of using corticosteroids with your healthcare physician if you are thinking about using them to treat a skeletal or muscular disease.

The administration of corticosteroid injections

A medical practitioner administers steroid injections in a clinic, hospital, or general practitioner’s office.

They can be administered in some methods, such as:

• Into a joint (an intra-articular injection)
• Into a muscle (an intramuscular injection)
• Into the spine (an epidural injection)
• Into the blood (an intravenous injection)

Some injections begin to act within a few hours, but most take a few days to start. Usually, a few weeks or months pass before the effect fades. This relieves the pain instantly and for a few hours.

Soon after the injection, you should be allowed to return home. For a few days, you might need to rest the affected area of your body.

Which condition is treated by injections of corticosteroids?

A doctor may administer a corticosteroid injection to treat any disease that results in
pain and inflammation, such as:

• Autoimmune diseases.
• Arthritis.
• Tendinitis.
• Tendinopathy.
• Bursitis.
• Carpal tunnel syndrome.
• Tennis elbow.
• Trigger finger and trigger thumb.

Injections of steroids provide short-term relief for several illnesses. They lessen inflammation and pain.

Steroid injections for sciatica

When a bulging or herniated spinal disk presses against a nerve root in your spine, it can cause sciatica, a painful element. Your sciatic nerve, which runs from your butt down both legs, becomes inflamed and painful as a result. Injections of steroids can lessen this pain. Up to three times a year, they are administered.

Steroid injections for plantar fasciitis

Inflammation of the plantar fascia, the connective tissue on the bottom of your foot, results in plantar fasciitis. Your heel may get extremely painful and stabbed as a result. Injecting steroids into your heel reduces inflammation and pain for around a month.

Steroid injections for keloids

Raised scar tissue known as keloids can form following skin injuries caused by trauma, body piercings, surgery, acne, and other conditions. Keloids can be made smaller and less irritating by injecting them with steroids. To stop keloids from developing at the site of the incision, doctors may advise steroid injections before surgery.

Steroid injections for bursitis

Fluid-filled sacs called bursae (plural of bursa) act as cushions and lessen friction between bones, tendons, ligaments, and skin. Usually, it affects your hips, elbows, knees, and shoulders. When administered to the region around the injured bursa, steroid injections reduce inflammation and increase pain.

Steroid injections for tendinitis

Inflammation of the tendons, which are the tissues that connect your muscles and bones, is known as tendinitis. It frequently affects the knees, elbows, and shoulders and is frequently caused by overuse or strain injuries. One of the most prevalent forms of tendinitis is tennis elbow. To promptly increase pain and swelling, your physician will administer a steroid injection straight into the injured tendon.

Steroid injections for arthritis

One or more joints become painfully inflamed when someone has arthritis. Steroid injections can quickly reduce pain in your ankles, hips, elbows, knees, shoulders, hands, feet, spine, and wrists.

Other conditions

For pain and inflammation caused by other medical disorders, your doctor might suggest steroid injections, such as:

• Autoimmune conditions like multiple sclerosis and lupus
• Inflamed spinal nerves and back pain can make your arms and legs hurt.
• A pinched nerve in your neck causes cervical radiculopathy, which results in pain in your hands, arms, shoulders, and neck.
• A pinched nerve in your wrist is known as carpal tunnel syndrome.
• Trigger thumb and trigger finger: these make your affected finger feel like it’s locking.

Side effects of corticosteroid injections

The location of the steroid injection determines any potential adverse effects.

The following adverse effects could result from injections into the joints, muscles, or spine:

• Paracetamol may increase the pain and suffering that lasts for a few days, as well as any brief bruises or blood clots beneath the skin that flush the face for a few hours.
• Vision changes, such as blurred vision; consult your expert if this occurs due to an infection that is causing pain, swelling, and redness. You should get medical help immediately if you have any of these symptoms.
• A decrease in body fat where the injection was administered. The skin around the injection site may become permanently paler, and this could result in dimples in the skin.
• Pain where the injection was made.
• A brief rise in swelling.
• Bruising.
• High blood sugar levels for a short time. After receiving a corticosteroid injection, diabetics should monitor their blood sugar levels more often for around five days.
• Redness or discoloration where the injection was made.
• Paler or lighter skin around the injection site.

The majority of corticosteroid injection recipients experience no negative side effects. Although they may experience some pain during the injection, many patients find that this is not as horrible as they had anticipated.

Within the first 24 hours following an injection, some persons experience a flare-up in their joint pain. Simple painkillers like paracetamol will help, but this normally goes away on its own in a few days. The stronger mixes of triamcinolone and methylprednisolone have the highest risk of adverse effects. Sometimes, especially with the harsher ones, injections can result in some thinning or color changes at the injection site. Rarely, you could have a joint infection while receiving an injection. See your doctor right away if your joint starts to hurt and get heated, especially if you’re feeling ill.

People frequently worry about the potential for further steroid-related adverse effects, like weight gain. The fact that the dosage can frequently be maintained low is one benefit of steroid injections over tablets. This indicates that unless injections are administered regularly, more than a few times a year, these additional side effects are quite uncommon.

Women’s periods may occasionally experience brief disruptions as a result of receiving steroid injections. Additionally, they can alter people’s moods; you might experience extreme highs or lows. If you have a history of mood disorders, this might be more likely. Please talk to your doctor about this if you’re concerned.

Your blood pressure may rise for a few days if you have high blood pressure.

Occasionally, epidural injections can also cause painful headaches that only go away when you lie down. Tell your doctor if you experience any symptoms, but this should resolve independently.

Increased hunger, mood swings, and trouble sleeping (insomnia) are common side effects of blood injections that are comparable to those of steroid tablets. You might be given a blue steroid treatment card that details ways to lower the risk of side effects if you’ve been receiving steroid injections for more than a few weeks or if you’ve been prescribed a high dose. A red steroid emergency card might also be issued to you.

Show your blue or red steroid card to the doctor, dentist, or pharmacy if you require any medical or dental care so they are aware that you are receiving steroid injections.

Yellow Card, the UK safety program, is the place to report any potential side effects. Although serious side effects from steroid injections are uncommon, they can include:

• Infections at the place of injection.
• Hypertension, or elevated blood pressure.
• Increased edema and fluid retention.
• Individuals who get steroid injections frequently may be more susceptible to osteoporosis.

Who can have corticosteroid injections?

Steroid injections are safe for the majority of people.

Before receiving therapy, let the doctor know if you:

• Have received four steroid injections in the past year; typically, you must wait at least three months between doses; have received a steroid injection in the past few weeks; Doctors typically advise against receiving more than four injections in the same location during 12 months if the patient has previously experienced a steroid allergic response or an infection, especially an eye infection.
• have recently received or will soon receive any vaccines; are expecting, nursing, or attempting to conceive a child
• Have you been diagnosed with diabetes, epilepsy, high blood pressure, liver, heart, or kidney problems? Are you currently on any other medications, such as anticoagulants?
• In these situations, steroid injections might not always be appropriate, but if the doctor believes the advantages outweigh the dangers, they might suggest them.

When is getting a corticosteroid injection inappropriate?

If you have an infection, you shouldn’t have steroid injections. Corticosteroids can hinder your body’s ability to fight off infections and recover itself, and they have a short-term immunosuppressive effect.

Steroid injections may not be an option for people with bleeding disorders (such as hemophilia) or those using blood-thinning drugs (anticoagulants). Inform your healthcare practitioner about your illnesses, your management strategies, and any medications or supplements you take.

How corticosteroid injections work

The effects of hormones that are typically produced by the adrenal glands, two little glands located above the kidneys, are closely mimicked by steroids.

Steroid injections into a muscle or joint lessen inflammation, or the surrounding redness and swelling. Stiffness and soreness may be lessened by doing this. They can lower the body’s overall level of inflammation and the immune system’s activity, which is the body’s natural defense against disease and infection, when injected into the circulation.

Multiple sclerosis (MS) and other autoimmune diseases, which are caused by the immune system unintentionally attacking the body, may benefit from this treatment. Anabolic steroids, which some people use illegally to gain muscular mass, are not the same as steroid injections.

How is it taken?

The best steroid combination and dosage for you will be discussed with you by your physician or nurse. Your symptoms and condition will determine this.

Because steroid injections might raise blood pressure and blood sugar, they might want to check them before your first shot. If either is brought up, they may postpone the injection.

Steroid injections can be administered based on the location of the pain and inflammation:

• Straight into an inflammatory joint (an intra-articular injection); into the soft tissue surrounding the joint (a peri-articular injection); or into a muscle (an intra-muscular injection).
• The majority of injections are simple and quick to administer.

To ensure that the steroid is injected precisely where it will be most effective, you might need an ultrasound scan to determine the location of the inflammation. High-frequency sound waves are used in an ultrasonic scan to produce an image of a portion of the body’s interior. Numerous injections can be administered without ultrasonography.

To make the injection less painful, you may occasionally receive a local anesthetic along with the steroid. This implies that your pain should subside in a matter of minutes. Unless a long-acting anesthetic is administered, the effects of local anesthetics can wear off in as little as 30 minutes. The anesthetic may cause some numbness in you that may persist for up to 24 hours.

If you’re getting a steroid injection, loose-fitting clothing might be more comfortable. After your steroid injection, you could be told to wait in the clinic for ten to fifteen minutes. Being around medical specialists might be beneficial if you do experience any sort of reaction to the injection.

After the injection, you might want to make arrangements for transportation home, particularly if you’ll be receiving a local anesthetic, as the numbness from the anesthetic may make driving challenging.

Steroid injections are frequently helpful in the short term for some illnesses, such as inflammatory kinds of arthritis, while you and your doctor determine the best long-term medication to manage your arthritis. In this instance, the need for injections should decrease once your arthritis is under control.

How Do You Give corticosteroids?

A needle will be used to provide your shot. The process changes according to the shot’s intended use. Usually, your doctor will place a needle beneath your skin where the pain is. In some cases, your doctor might numb the area where the steroid injection is given with a local anesthetic.

However, some injections require a more intricate procedure. Your doctor may use imaging tools like an ultrasound or CT scan to guide the needle to the part of your body that needs to be treated. After it’s in the proper position, you’ll receive an injection of steroids after an anesthetic to numb the area.

Steroid injections can also be administered by intravenous infusion. In this kind of procedure, a medical professional puts a needle into your vein, and over a predetermined amount of time, the steroid enters your circulation. You will receive an intravenous infusion in a hospital or at an outpatient infusion clinic.

What’s the duration of a corticosteroid?

The way each person’s body reacts to a corticosteroid injection varies. The typical duration of steroid injections is a few weeks to a few months. The corticosteroid injection should be beneficial for as long as it takes for your body to heal completely if you have inflammation following an injury.

If you suffer from persistent inflammation, you may eventually discover that your symptoms are progressively returning. Consult your physician if you experience new or worsening irritation.

Risks factor

Higher dosages and more frequent use of corticosteroid injections raise the risk of adverse effects. Some possible side effects are:

• Cartilage damage.
• Death of nearby bone.
• Joint infection.
• Nerve damage.
• Short-term facial flushing.
• Brief flare-up of joint pain, edema, and irritation.
• Short-term increase in blood sugar.
• Tendon weakening or rupture.
• Bone thinning in the area (osteoporosis).
• Soft tissue and skin thinning surrounding the injection site.
• Skin lightening near the injection site.

Obtaining a prescription for corticosteroids

Your healthcare provider might give you a steroid card to keep with you if you’ve had a steroid injection into a joint or muscle. This will include information on the treatment you received.

Injections of steroids can prevent the body from making its hormones, which can be harmful if you become sick, have an accident, or require surgery. Evidence suggests that following just one steroid injection, this risk may persist for up to one month. This risk may persist for an additional 12 months if you have received three steroid injections in 12 months.

Having the card on hand will make it easier for any other medical professional who treats you to properly manage your treatment. Speak with the medical expert who prescribed your steroids if you have any queries or worries about this.

How frequently is a corticosteroid injection possible?

To reduce pain and inflammation, you may only require one corticosteroid injection, particularly if you’re healing from a transient injury. You may require additional steroid injections in the future if you have a chronic (long-term) condition.

When it’s safe for you to have another dose, your doctor will let you know. Between steroid cycles, you’ll most likely need to wait at least three months. The average person should only receive three vaccinations annually.

Is injecting corticosteroid safe?

Corticosteroid injections and other corticosteroid forms prescribed by a physician are safe. They will administer the injection themselves and advise you on the kind of medication you will require.

It is not safe to use anabolic steroids recreationally or without a doctor’s prescription. Compared to what doctors prescribe to address medical disorders, nonprescription doses are frequently 10–100 times larger. Nonprescription steroid injections typically cause more serious and sometimes fatal side effects.

Before receiving a corticosteroid injection, is there anything more I should know?

If you have an infection, especially in the area of your body that requires treatment, you will not be able to have a steroid injection.

Because receiving a steroid injection can cause your blood sugar levels to rise for a few days following the injection, you should talk to your doctor or other healthcare provider about this if you have diabetes. Following a steroid injection, it’s critical to keep an eye on your blood sugar levels.

There is proof that administering too many steroid injections in one location can harm internal body tissue. Most likely, your doctor will advise against receiving more than three steroid injections in the same area of your body in a single year. Your symptoms may dictate that you should have less than that. You should talk to your doctor if you have hemophilia, a disorder that causes blood to clot improperly, as you may be more susceptible to bleeding into your joint.

It’s important not to overdo it during the first two weeks after a steroid injection. After receiving a steroid injection, there is a slight chance that overexerting a joint could cause tendon injury. Strong cords called tendons connect muscles to bones. It’s crucial to keep doing whatever activities your healthcare provider has prescribed after this period. Increase the amount you do progressively after starting slowly.

Your physical therapist will assist you in striking the ideal balance between activity and rest if you are receiving physical therapy.

Can I use corticosteroid injections and other medications at the same time?

Steroid injections can be taken alongside other medications. To ensure that your blood is not too thin for the injection, you might require an additional blood test if you’re using an anticoagulant, which is a medication that thins the blood (warfarin, for example). The possibility of bleeding into the joint is the reason behind this.

You should let the person administering the injection know that you take anticoagulants. It might be suggested that you modify your warfarin dosage before receiving the steroid injection.

What function do corticosteroid injections serve in a comprehensive treatment strategy?

Depending on your situation, your doctor might prescribe steroid injections in addition to painkillers, anti-inflammatory medications, physical therapy, occupational therapy, or braces and canes.

For instance, tendinitis may be treated with a local steroid injection if you have no other medical issues. Injections, however, are only one component of your treatment strategy if you suffer from a condition like rheumatoid arthritis.

Does a corticosteroid injection impact upcoming procedures?

Although corticosteroid injections are useful in lowering pain and inflammation, they also negatively impact chondrocytes, which are the cells that keep joints smooth. This may hasten the course of arthritis, making it worse.

Knowing this is crucial if you are thinking about joint restoration procedures like autologous chondrocyte implantation or microfracture, as a corticosteroid injection may make regeneration procedures less successful. Your doctor or provider may limit or forbid corticosteroid before a joint restoration treatment because the goal of joint repair is to maintain existing cartilage.

If you are thinking of replacing your joints, the negative impact on chondrocytes is less significant. During a joint replacement, deteriorated bone and cartilage are removed and replaced with metal and plastic parts. The state of the cartilage and any further harm caused by corticosteroid injections won’t have an impact on the joint replacement result because the complete joint surface is replaced. To reduce the risk of infection, replacement surgery in that joint should be postponed for at least three months after receiving a corticosteroid injection.

Conclusion

Injections of steroids provide efficient, however short-term, relief from inflammation-related pain. They are a safe treatment for the majority of people. However, receiving steroid injections frequently increases your risk of experiencing severe adverse effects, and they don’t mix well with other drugs or medical conditions. Discuss your medical history and any current medications or supplements you take with your doctor before receiving a steroid injection.
