Can't Get Atovaquone/Proguanil? Here Are Your Alternatives
Atovaquone/Proguanil (Malarone) is one of the most popular antimalarials for travelers — but what happens when you can't fill your prescription? Whether it's out of stock, too expensive, or your insurance won't cover it, you have several solid alternatives for malaria prevention.
In this guide, we'll compare the main alternatives to Atovaquone/Proguanil, including how they work, what they cost, their side effects, and which might be the best fit for your situation.
Why You Might Need an Alternative
There are several reasons patients look for alternatives to Atovaquone/Proguanil:
- Availability — Your pharmacy may not have it in stock (learn why it can be hard to find)
- Cost — Even generic Atovaquone/Proguanil costs $43-$70 with coupons, which is more expensive than some alternatives (see our savings guide)
- Side effects — Some patients experience nausea, abdominal pain, or headaches (read about Atovaquone/Proguanil side effects)
- Drug interactions — Atovaquone/Proguanil interacts with rifampin, rifabutin, tetracycline, and warfarin (more in our drug interactions guide)
- Contraindications — Patients with severe kidney disease (CrCl below 30 mL/min) cannot use it for prophylaxis
The Main Alternatives to Atovaquone/Proguanil
1. Doxycycline
The affordable workhorse. Doxycycline is a tetracycline antibiotic that's widely used for malaria prevention and is available at virtually every pharmacy in the country.
- How it works: Inhibits protein synthesis in malaria parasites
- Dosing: 100 mg daily, starting 1-2 days before travel, continuing during travel and for 4 weeks after leaving the malaria area
- Cost: Very affordable — typically $10-$30 for a full course, even without insurance
- Pros: Cheap, widely available, also protects against some other travel infections (rickettsial diseases, leptospirosis)
- Cons: Must take for 4 weeks after travel (vs. 7 days with Atovaquone/Proguanil), causes photosensitivity (increased sunburn risk), GI upset, vaginal yeast infections in women, cannot be used in children under 8 or pregnant women
- Best for: Budget-conscious travelers, long trips (cheaper for extended courses), travelers who also want protection against other infections
2. Mefloquine (Lariam)
The weekly option with caveats. Mefloquine is effective against malaria in most regions and has the convenience of once-weekly dosing.
- How it works: Acts as a blood schizonticide, disrupting the parasite's food vacuole
- Dosing: 250 mg once weekly, starting 2 weeks before travel, continuing weekly during travel and for 4 weeks after
- Cost: $30-$80 for a typical course (generic available)
- Pros: Weekly dosing, effective in most malaria areas, can be used in pregnancy (2nd and 3rd trimesters)
- Cons: FDA boxed warning for neuropsychiatric side effects — can cause anxiety, depression, vivid nightmares, dizziness, psychosis, and in rare cases, long-lasting effects. Not for patients with seizure disorders, psychiatric conditions, or cardiac conduction abnormalities
- Best for: Travelers who prefer weekly dosing and have no history of psychiatric conditions
3. Chloroquine (Aralen)
The classic — but only for certain destinations. Chloroquine was once the go-to antimalarial but is now limited by widespread resistance.
- How it works: Accumulates in parasite food vacuoles and inhibits heme polymerization
- Dosing: 500 mg (300 mg base) once weekly, starting 1-2 weeks before travel, continuing for 4 weeks after
- Cost: $30-$60 for a typical course
- Pros: Weekly dosing, well-tolerated, long track record, safe in pregnancy
- Cons: Only effective in chloroquine-sensitive areas (parts of Central America, Caribbean, Middle East). Most of Africa and Southeast Asia have chloroquine-resistant malaria
- Best for: Travelers to chloroquine-sensitive regions only — check CDC guidelines for your destination
4. Tafenoquine (Arakoda)
The newer weekly option. Tafenoquine was FDA-approved in 2018 and offers the convenience of weekly dosing with a shorter post-travel course than mefloquine or doxycycline.
- How it works: Targets the mitochondria of malaria parasites (similar to atovaquone) and also has activity against liver-stage parasites
- Dosing: Loading dose of 200 mg daily for 3 days before travel, then 200 mg weekly during travel, then 200 mg once in the week after returning
- Cost: $500-$700+ for a course (expensive; limited insurance coverage)
- Pros: Weekly dosing during travel, short post-travel course, active against liver-stage P. vivax
- Cons: Requires G6PD testing before starting (contraindicated in G6PD-deficient patients), expensive, limited availability, can cause psychiatric symptoms. Not for use in pregnancy or children under 18
- Best for: Travelers who want weekly dosing and a short post-travel course, confirmed G6PD-normal
Quick Comparison Table
Here's how the alternatives stack up against Atovaquone/Proguanil:
- Atovaquone/Proguanil: Daily dosing | Start 1-2 days before | 7 days after travel | ~$43-$70 (generic w/ coupon) | Well-tolerated
- Doxycycline: Daily dosing | Start 1-2 days before | 4 weeks after travel | ~$10-$30 | Photosensitivity, GI upset
- Mefloquine: Weekly dosing | Start 2 weeks before | 4 weeks after travel | ~$30-$80 | Neuropsychiatric risk (boxed warning)
- Chloroquine: Weekly dosing | Start 1-2 weeks before | 4 weeks after travel | ~$30-$60 | Only for sensitive areas
- Tafenoquine: Weekly dosing | Start 3 days before | 1 dose after travel | ~$500-$700 | Requires G6PD test, expensive
How to Choose the Right Alternative
The best alternative depends on your specific situation:
- Check your destination — Use the CDC's malaria information by country to see which drugs are effective in your travel area
- Consider your budget — If cost is the main concern, Doxycycline is by far the cheapest option
- Think about convenience — If you prefer weekly dosing, Mefloquine or Tafenoquine may be better fits
- Review your health history — Psychiatric history rules out Mefloquine; G6PD deficiency rules out Tafenoquine; pregnancy limits options to Chloroquine or Mefloquine (2nd/3rd trimester)
- Talk to your doctor — A travel medicine specialist can help match the right drug to your destination, health profile, and preferences

The Bottom Line
Atovaquone/Proguanil is a great antimalarial, but it's not the only option. Doxycycline offers the best value, Mefloquine and Tafenoquine offer weekly convenience, and Chloroquine works well for specific destinations. Work with your healthcare provider to find the safest and most practical choice for your trip.
