1Introduction
Atovaquone/Proguanil 250mg/100mg Tablets are a generic version of Malarone, a dual-action antimalarial medication used for the prevention and treatment of malaria. Malaria is a potentially life-threatening disease caused by parasites transmitted through mosquito bites in tropical regions, particularly Africa, Asia, and parts of Central and South America.
These tablets are ideal for adult travellers seeking reliable malaria protection, and they are often recommended for travel to regions where Plasmodium falciparum malaria is resistant to older drugs such as chloroquine or mefloquine.
How It Works
Atovaquone and Proguanil work synergistically to block key processes essential for the parasite’s survival:
Atovaquone inhibits mitochondrial electron transport in the parasite
Proguanil inhibits dihydrofolate reductase, an enzyme needed for DNA replication
This dual mechanism makes the combination particularly effective and reduces the likelihood of resistance development.
Why Choose Atovaquone/Proguanil Tablets
This medication is widely used and recommended by travel clinics and the NHS for short-term malaria protection. It is known for its high efficacy and convenient once-daily dosing.
Key benefits include:
Generic version of Malarone – cost-effective yet equally effective
Prevents and treats falciparum malaria
Well tolerated with low risk of serious side effects
Short dosing window – only 7 days post-travel
Suitable for last-minute travellers
Important Note
Start taking the tablets 1–2 days before entering a malaria zone, continue daily during your stay, and for 7 days after returning. Missing doses can compromise protection. If vomiting occurs within 1 hour of taking a dose, repeat the dose. Store in a cool, dry place and keep out of reach of children.
