Malaria Treatment: Why Antibiotics Don't Work & What Does
Malaria is caused by Plasmodium parasites (protozoa), not bacteria. Antibiotics target bacteria—they are ineffective against malaria.
Correct Treatment
- Artemisinin-based Combination Therapies (ACTs): First-line for uncomplicated P. falciparum (e.g., artemether-lumefantrine, artesunate-amodiaquine).
- Chloroquine: For chloroquine-sensitive P. vivax, P. ovale, P. malariae, P. knowlesi.
- Primaquine: Radical cure for P. vivax/ovale hypnozoites (G6PD test first).
- Severe malaria: IV artesunate → transition to ACT.
Antibiotics with Antimalarial Activity (Exceptions)
- Doxycycline: Prophylaxis + adjunct treatment (inhibits apicoplast).
- Clindamycin, azithromycin: Adjuncts in combination regimens.
These are adjuncts, not monotherapy. Never treat suspected malaria with antibiotics alone.
Prevention
- Chemoprophylaxis (doxycycline, atovaquone-proguanil, mefloquine)
- Insecticide-treated nets, repellents, indoor residual spraying
- RTS,S/AS01 vaccine (children in endemic areas)
