Hydroxychloroquine tablet (HCQ) is not a steroid; rather, it is a medication classified as an antimalarial and immunomodulatory agent. It is commonly used to treat malaria, rheumatoid arthritis, lupus erythematosus, and other autoimmune diseases. While it shares some therapeutic uses with steroids, such as anti-inflammatory effects, HCQ acts through different mechanisms.
Mechanism of Action:
HCQ’s primary mechanism of action involves interfering with the function of lysosomes in cells, which inhibits various cellular processes, including antigen presentation and cytokine production. Additionally, HCQ may alter the pH of intracellular vesicles, impairing the function of immune cells such as macrophages and dendritic cells.
Anti-inflammatory Effects:
HCQ has mild immunomodulatory and anti-inflammatory properties. It can reduce the production of inflammatory cytokines, such as tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6), and inhibit the activation of immune cells involved in the inflammatory response. you can also buy hydroxychloroquine online at dosepharmacy
- Malaria: HCQ is widely used for the prevention and treatment of malaria caused by Plasmodium species. It is often used in combination with other antimalarial medications for optimal efficacy.
- Rheumatoid Arthritis: HCQ is prescribed to manage symptoms of rheumatoid arthritis, including joint pain and swelling. It may also slow down the progression of joint damage.
- Lupus Erythematosus: HCQ is a cornerstone therapy for systemic lupus erythematosus (SLE) and discoid lupus erythematosus (DLE). It helps control disease activity, reduce skin lesions, and prevent flares.
- Other Autoimmune Diseases: HCQ may be used off-label to manage other autoimmune conditions, such as Sjögren’s syndrome and dermatomyositis.
Comparison with Steroids:
While both HCQ and steroids have anti-inflammatory properties, they differ in their mechanisms of action and therapeutic uses. Steroids, such as prednisone and dexamethasone, exert broad immunosuppressive effects by inhibiting the production of inflammatory mediators and suppressing immune responses. They are often used in acute inflammatory conditions or as adjunctive therapy for severe autoimmune diseases. In contrast, HCQ has a more targeted and mild immunomodulatory effect, making it suitable for long-term use in chronic autoimmune diseases with less risk of adverse effects associated with prolonged steroid use.
Safety Profile:
HCQ is generally well-tolerated when used at recommended doses. However, prolonged use or high doses may increase the risk of adverse effects, including retinopathy, cardiomyopathy, and QT interval prolongation. Regular monitoring of patients receiving HCQ therapy is essential to detect and manage potential side effects.

Steroids: These are medications that mimic the effects of the natural hormone cortisol produced by the adrenal glands. They have potent anti-inflammatory and immunosuppressive properties and are used to treat a variety of conditions like autoimmune diseases and asthma. Examples of steroids include prednisone and methylprednisolone.

Hydroxychloroquine: This medication primarily functions as an antimalarial drug. It can also be used to manage certain autoimmune diseases like lupus and rheumatoid arthritis due to its anti-inflammatory properties. However, its mechanism of action for these conditions is not fully understood and differs from how steroids work.
Conclusion:
In summary, hydroxychloroquine is not a steroid but rather an antimalarial and immunomodulatory medication used in the treatment of malaria and various autoimmune diseases. While it shares some anti-inflammatory properties with steroids, it acts through different mechanisms and is considered safer for long-term use in chronic autoimmune conditions. As with any medication, HCQ should be used judiciously, and patients should be monitored for potential side effects.
