Browse Medications by Drug Class: Corticosteroids

Corticosteroids are anti-inflammatory medications that mimic the effects of natural cortisol produced by the adrenal glands. They are available in various forms, including eye drops for localized ocular treatment and systemic formulations (oral, intravenous, or intramuscular) for whole-body effects. Corticosteroid eye drops reduce inflammation in the conjunctiva, cornea, and other ocular tissues, while systemic corticosteroids address inflammation throughout the body, making them effective for conditions such as autoimmune diseases, allergic reactions, and severe infections. A defining characteristic of corticosteroids is their ability to modulate the immune system and suppress inflammatory pathways by inhibiting the release of inflammatory mediators like cytokines and prostaglandins.

Corticosteroids were first discovered in the 1940s, with cortisone becoming one of the earliest breakthrough treatments for inflammatory and autoimmune diseases. By the 1950s, prednisone and dexamethasone were developed, providing more potent and long-acting options. In the 1960s, corticosteroid eye drops became available, offering targeted anti-inflammatory relief for ocular conditions without systemic side effects. Over the years, corticosteroids have evolved into a cornerstone treatment for conditions ranging from uveitis and ocular allergies to rheumatoid arthritis and systemic lupus erythematosus (SLE). These medications have transformed the management of inflammatory diseases, improving patient outcomes and quality of life.

Corticosteroids work by binding to glucocorticoid receptors in cells and influencing gene expression to suppress inflammatory responses: ^ Inhibition of Cytokine Production: Corticosteroids prevent the release of pro-inflammatory cytokines such as interleukin-1 (IL-1) and tumor necrosis factor-alpha (TNF-α). ^ Suppression of Immune Cell Activity: These medications reduce the activity of immune cells, such as macrophages and T-cells, that contribute to inflammation. ^ Reduction of Vascular Permeability: By stabilizing capillary membranes, corticosteroids decrease fluid leakage, reducing tissue swelling and inflammation. ^ Localized vs. Systemic Action: Eye drops act locally, reducing inflammation in the anterior segment of the eye without systemic absorption. Systemic corticosteroids affect the entire body, making them useful for conditions involving widespread inflammation. This dual approach allows corticosteroids to address inflammation at the site of injury (localized) or systemically for broader autoimmune and allergic conditions.

Corticosteroids are generally safe when used as directed but may cause side effects. Common side effects of corticosteroid eye drops include blurred vision, eye discomfort, and increased intraocular pressure. Systemic corticosteroids may cause weight gain, increased appetite, and mood changes. Long-term use of systemic corticosteroids can lead to osteoporosis, adrenal suppression, hypertension, and increased susceptibility to infections. Patients should be closely monitored, especially during long-term therapy, and doses should be tapered gradually to prevent withdrawal symptoms.

Corticosteroid eye drops are generally considered safe during pregnancy due to their minimal systemic absorption. Systemic corticosteroids may be prescribed for conditions such as autoimmune flare-ups or severe asthma when the benefits outweigh the risks. Pregnant individuals should consult their healthcare provider to ensure appropriate dosing and monitor for potential complications.

Corticosteroid eye drops are considered safe during lactation due to their localized action and low systemic absorption. Systemic corticosteroids may pass into breast milk in small amounts but are generally considered safe at low doses or for short durations. Patients should consult their healthcare provider to ensure safe use while breastfeeding.

Corticosteroids are not classified as controlled substances. However, they require a prescription due to their potent anti-inflammatory effects and the need for proper dosing and monitoring to prevent side effects.

Corticosteroids are generally well-tolerated when used as prescribed, but side effects may occur. Common side effects of eye drops include blurred vision, eye discomfort, and mild burning. Less common side effects of eye drops include increased intraocular pressure and secondary infections. Systemic corticosteroids may cause side effects such as weight gain, fluid retention, and elevated blood sugar levels. Rare but serious side effects of systemic corticosteroids include osteoporosis, adrenal insufficiency, Cushing's syndrome, and psychological effects such as mood swings and depression. Patients should seek medical attention if they experience symptoms such as severe headaches, blurred vision, or extreme fatigue.

The cost of corticosteroid medications varies depending on the formulation. Generic corticosteroid eye drops and systemic tablets, such as prednisone, are generally affordable, while brand-name eye drops or injections may be more expensive. Most insurance plans cover corticosteroids for FDA-approved indications, including ocular inflammation, autoimmune diseases, and asthma.
