Plaquenil 200 mg (Hydroxychloroquine)

What Is Plaquenil 200 mg?

Plaquenil is the brand name for Hydroxychloroquine Sulfate, and each tablet contains 200 mg of the active substance. Originally developed as an antimalarial drug, it is now more widely used for:

• Rheumatoid arthritis (RA)

• Systemic lupus erythematosus (SLE)

• Discoid lupus

• Juvenile idiopathic arthritis (off-label)

• Certain dermatologic and autoimmune conditions

Hydroxychloroquine helps control overactive immune responses, making it valuable in autoimmune diseases where the body attacks its own tissues.

How Does Plaquenil 200 mg Work?

Hydroxychloroquine works through multiple mechanisms:

1. Alters immune cell communication to reduce inflammation.

2. Inhibits the action of certain enzymes involved in immune responses.

3. Accumulates in cells and interferes with lysosomal activity and antigen processing.

4. Modifies the pH within immune cells, disrupting abnormal immune activity.

In malaria, it works by interfering with parasite digestion of red blood cells. In autoimmune diseases, it helps reduce joint pain, rashes, swelling, and fatigue without being a direct painkiller.

Benefits of Plaquenil 200 mg

1. Autoimmune Disease Control

It helps manage flare-ups in lupus and rheumatoid arthritis by suppressing immune overactivity and decreasing inflammation.

2. Joint and Skin Symptom Relief

3. Malaria Prevention and Treatment

Plaquenil is effective against Plasmodium falciparum and Plasmodium vivax, the most common malaria-causing parasites.

4. Steroid-Sparing Agent

Can reduce the need for corticosteroids in chronic autoimmune disease treatment, minimizing long-term steroid side effects.

5. Long-Term Use Tolerability

Hydroxychloroquine is generally well-tolerated for long-term daily use, making it suitable for chronic disease management.
