Types of Steroids: A Complete Medical Overview

Corticosteroids are prescription medicines that can reduce inflammation, allergic reactions, and excessive immune activity. Anabolic-androgenic steroids may have limited medical uses but are also misused to increase muscle size or athletic performance.
Key Takeaways
- Corticosteroids are prescription medicines that can reduce inflammation, allergic reactions, and excessive immune activity.
- Anabolic-androgenic steroids may have limited medical uses but are also misused to increase muscle size or athletic performance.
- Steroid treatment can be safe and effective when the type, dose, route, and duration are selected and monitored by a clinician.
- Side effects vary substantially between short-term and long-term use, and between topical, inhaled, injected, and oral medicines.
- Prescription steroids should not be started, stopped, shared, or changed without medical guidance.
The main types of steroids are corticosteroids, which are prescribed to control inflammation and immune activity, and anabolic-androgenic steroids, which are synthetic forms of testosterone. Although the word “steroids” is often used broadly, these groups have different medical purposes, effects, and safety considerations.
Overview: What Are the Different Types of Steroids?
Types of steroids are commonly divided into two major groups: corticosteroids and anabolic-androgenic steroids. Corticosteroids are medicines that resemble cortisol, a hormone naturally made by the adrenal glands. They are widely used to reduce inflammation, calm an overactive immune response, and treat conditions affecting the skin, lungs, joints, bowel, eyes, and other organs.
Anabolic-androgenic steroids are synthetic substances related to testosterone. Certain forms are prescribed for specific medical reasons, such as some hormone deficiencies or conditions associated with significant muscle loss. However, they are also sometimes used without medical supervision for muscle building or performance enhancement, which can cause serious health effects.
The term “steroid” can therefore be misleading without context. It does not automatically mean a harmful drug, nor does it mean that all steroid medicines have the same effects. A person’s safety depends on the specific medicine, how it is taken, the dose, treatment duration, underlying health conditions, and clinical monitoring.
Corticosteroids: Anti-Inflammatory Steroid Medicines
Corticosteroids, often simply called corticosteroids or “cortisone-like” medicines, imitate the effects of cortisol. Cortisol helps regulate inflammation, metabolism, stress responses, and immune function. In medical treatment, corticosteroids can be especially useful when inflammation itself is causing symptoms or damaging tissues.
These medicines are available in several forms. The chosen form helps deliver treatment to the affected area while limiting unnecessary exposure elsewhere in the body. For example, an inhaled medicine may be appropriate for airway inflammation, while a cream may be used for a localized skin condition.
- Topical corticosteroids: creams, ointments, lotions, and scalp preparations for inflammatory skin conditions.
- Inhaled corticosteroids: medicines used to control airway inflammation in conditions such as asthma.
- Nasal corticosteroids: sprays that may reduce nasal inflammation from allergies or sinus-related symptoms.
- Oral corticosteroids: tablets or liquids used when a stronger whole-body effect is needed.
- Injected corticosteroids: injections into a joint, soft tissue area, vein, or muscle in selected circumstances.
- Eye-drop corticosteroids: prescribed for certain inflammatory eye conditions under specialist supervision.
Examples of corticosteroid medicines include hydrocortisone, prednisone, prednisolone, dexamethasone, methylprednisolone, budesonide, and fluticasone. These medicines differ in strength, duration of action, and recommended use. They should be used only as prescribed, particularly when they are taken by mouth or injection.
Anabolic-Androgenic Steroids and Testosterone-Related Medicines
Anabolic-androgenic steroids, often called anabolic steroids, have effects related to testosterone. “Anabolic” refers to their potential to promote tissue building, including muscle tissue, while “androgenic” refers to effects associated with male sexual development. Testosterone itself is an important hormone in people of all sexes, although typical levels and clinical uses differ.
Doctors may prescribe testosterone or related medicines when testing and symptoms support a diagnosis of hormone deficiency. Some anabolic medicines may also be considered in limited specialist-managed situations. Treatment decisions involve careful assessment because hormone therapy can affect fertility, blood cell production, prostate health, mood, cholesterol levels, and other body systems.
Non-medical use of anabolic steroids, including use for bodybuilding or sports performance, is not the same as medically supervised hormone treatment. Products obtained outside regulated healthcare settings may be counterfeit, contaminated, incorrectly labeled, or used at unsafe doses. Combining several substances, sometimes called “stacking,” can further increase risk and makes side effects more difficult to predict.
Anabolic steroid misuse may contribute to acne, hair loss, high blood pressure, unfavorable cholesterol changes, liver problems, infertility, testicular shrinkage, menstrual changes, and emotional or behavioral changes. In adolescents, it can interfere with normal growth and development. Anyone using these substances should feel able to discuss them confidentially with a qualified healthcare professional.
How Steroid Medicines Are Used in Healthcare
Corticosteroids can be part of treatment for many inflammatory and immune-related conditions. They may be used for severe allergic reactions, asthma flare-ups, inflammatory bowel disease, autoimmune diseases, certain skin disorders, painful inflammatory joint conditions, and some neurologic or eye conditions. In many cases, they are used for a limited period while other therapies take effect or while symptoms are brought under control.
Local treatment is often preferred when it can adequately treat the problem. A topical cream, nasal spray, inhaler, or joint injection may provide benefit with less whole-body exposure than a tablet or intravenous medicine. However, even local steroid treatments can have side effects, particularly if used too frequently, at high strength, or for extended periods.
Oral or injected corticosteroids may be necessary when inflammation is severe, widespread, or affecting important organs. A clinician will generally aim to use the lowest effective dose for the shortest appropriate time. For long-term treatment, regular review can help balance symptom control with the risk of complications.
Some people use the word “steroid” when referring to treatments for asthma or inflammatory skin disease, while others mean testosterone-related substances. Clarifying the exact medicine is important when discussing benefits, possible interactions, or side effects with a healthcare team.
Possible Side Effects and Important Safety Considerations
Side effects from corticosteroids depend on the dose, formulation, and duration of use. Short courses may cause temporary changes such as increased appetite, indigestion, difficulty sleeping, mood changes, fluid retention, or raised blood sugar. Not everyone experiences these effects, and a clinician may recommend practical steps to reduce discomfort.
Longer-term or higher-dose systemic corticosteroid use can increase the chance of high blood pressure, diabetes or worsening blood sugar control, cataracts, glaucoma, thinning of the bones, muscle weakness, skin thinning, and increased susceptibility to infection. Regular monitoring may include blood pressure checks, blood tests, eye assessments, and attention to bone health, depending on the individual treatment plan.
People taking oral corticosteroids for more than a short period should not stop suddenly unless a clinician specifically advises it. The body can reduce its own cortisol production during treatment, and stopping abruptly may leave it temporarily unable to meet normal stress needs. A doctor may recommend a gradual dose reduction, known as tapering.
Before prescribing a steroid medicine, clinicians consider medical history, current medicines, vaccination status, pregnancy or breastfeeding, and conditions such as diabetes, osteoporosis, glaucoma, peptic ulcer disease, or active infection. It is also important to tell a healthcare professional about herbal products, supplements, and non-prescribed anabolic steroids.
Using Steroids Safely: Practical Self-Care and Monitoring
Prescription steroids work best when they are used exactly as directed. A person should follow instructions about timing, inhaler or spray technique, application amount, and the planned treatment length. For topical corticosteroids, using the correct strength on the correct body area is especially important because thinner skin, such as around the eyes or in skin folds, may be more sensitive.
For inhaled corticosteroids, rinsing the mouth and spitting out the water after use can help reduce the chance of oral thrush and hoarseness. Correct inhaler technique is also essential; a pharmacist, nurse, or doctor can demonstrate how to use the device. Nasal sprays should be directed away from the middle wall of the nose where possible, according to the product instructions.
People using long-term systemic corticosteroids may benefit from a personalized monitoring plan. This can include healthy nutrition, regular weight-bearing activity where appropriate, avoiding smoking, limiting alcohol, and keeping recommended appointments for blood pressure, blood sugar, bone, and eye checks. These measures support general health but do not replace medical follow-up.
It is not safe to share steroid medicines or use another person’s prescription. Steroid treatment should be reviewed if symptoms do not improve, if they return repeatedly, or if side effects become troublesome. A clinician can assess whether another medicine, a different route of treatment, or a specialist referral may be appropriate.
When to Seek Medical Care
Medical advice is important before starting any oral, injected, or anabolic steroid, and before using topical or inhaled products for longer than recommended. A clinician should review persistent symptoms rather than relying on repeated courses of steroid treatment, because the underlying cause may need a different approach.
Urgent medical assessment is appropriate for symptoms of a severe allergic reaction, including trouble breathing, swelling of the face or throat, widespread hives, or fainting. Prompt care is also needed for possible serious infection, such as high fever with marked illness, new confusion, severe weakness, or rapidly worsening symptoms while taking a steroid that affects the whole body.
A person taking corticosteroids should contact their healthcare professional if they develop significant vision changes, black or bloody stools, severe abdominal pain, extreme mood changes, unusually high thirst or urination, or signs of infection that are not improving. Those who have used oral corticosteroids regularly should seek advice before stopping them, including when they become acutely unwell or are planning surgery.
For international patients, Acibadem International’s multidisciplinary specialists and JCI-accredited hospitals can assess inflammatory, hormonal, and medication-related concerns and discuss appropriate treatment options. Care should always be individualized after a medical evaluation.
Frequently asked questions
Are corticosteroids the same as anabolic steroids?
No. Corticosteroids mainly reduce inflammation and modify immune activity, while anabolic-androgenic steroids have testosterone-like effects. Both are called steroids because of their chemical structure, but their medical uses and risks are different.
What are the most common types of corticosteroids?
Corticosteroids can be topical, inhaled, nasal, oral, injected, or used as eye drops. The best type depends on where inflammation is occurring and how severe it is.
Can steroid medicines cause weight gain?
Oral or injected corticosteroids can contribute to increased appetite, fluid retention, and weight gain, particularly at higher doses or with longer-term use. Local treatments such as creams or inhalers usually have less effect on body weight when used correctly.
Why should oral steroids not be stopped suddenly?
After regular use, oral corticosteroids can suppress the body’s natural cortisol production. Stopping suddenly may cause withdrawal symptoms or inadequate cortisol levels, so a clinician may need to reduce the dose gradually.
Are steroid creams safe to use?
Steroid creams can be safe and effective when the right strength is used for the correct condition and duration. Overuse, use on sensitive areas, or use of a strong product without supervision can cause skin thinning and other side effects.
Do anabolic steroids affect fertility?
Yes. Non-prescribed anabolic steroid use can reduce the body’s natural hormone production and may lower sperm production or disrupt menstrual cycles. Fertility may recover after stopping in some people, but the timing and degree of recovery can vary, so medical advice is recommended.
