Uses of Hydroxychloroquine 💊
Hydroxychloroquine is versatile and widely prescribed for both infectious and autoimmune diseases.
1. Malaria Prevention and Treatment
- Effective against Plasmodium falciparum and Plasmodium vivax
- Can be taken before, during, and after travel to malaria-prone regions
- Dosage and duration depend on risk level and patient profile
2. Autoimmune Conditions
- Lupus (SLE): Reduces inflammation, prevents flares

How Hydroxychloroquine Works
Hydroxychloroquine works by interfering with specific cellular processes:
- Malaria: Targets parasite growth in red blood cells
- Autoimmune diseases: Suppresses immune cell activity and inflammatory signals
- Mechanism Insight: Alters pH within immune cells, reducing autoantibody production
Example Table:
| Condition | Mechanism of Action |
|---|---|
| Malaria | Prevents parasite replication in RBCs |
| Lupus (SLE) | Modulates immune response and inflammation |
| Rheumatoid Arthritis | Reduces joint inflammation and pain |
