Malarone vs Doxycycline: Which Malaria Medication Is Right for You?
Comparing Malarone and doxycycline for malaria prevention. A physician breaks down side effects, cost, dosing schedules, and which antimalarial is right for your trip.
Malarone vs Doxycycline: Which Malaria Medication Is Right for You?
You're headed somewhere incredible (maybe a safari in Kenya, trekking through Southeast Asia, or backpacking Central America) and your doctor says you need malaria pills. So you start Googling, and now you're staring at two options: Malarone and doxycycline.
Both work. Both are recommended by the CDC. But they're different in ways that actually matter for your trip, from how long you take them to what they cost to whether you can sit in the sun without turning into a lobster.
Here's the honest breakdown from a physician's perspective.
What Are Malarone and Doxycycline?
Malarone is the brand name for atovaquone-proguanil, a combination medication designed specifically for malaria prevention and treatment. It works by attacking the malaria parasite at two different stages of its life cycle: atovaquone cuts off the parasite's energy supply while proguanil blocks its ability to replicate DNA.
Doxycycline is a tetracycline antibiotic that's been around for decades. While it's prescribed for everything from acne to Lyme disease, it's also highly effective at preventing malaria. It works by stopping the malaria parasite from producing the proteins it needs to survive inside your red blood cells.
Both are taken as daily pills, and both are considered first-line options by the CDC for travel to areas with chloroquine-resistant malaria, which is most malaria-endemic regions worldwide.
How They Compare: The Key Differences
Here's the side-by-side that actually matters when you're deciding between the two.

Side Effects: What to Actually Expect
This is where the two medications diverge the most, and it's usually what tips the decision for most travelers.
Malarone Side Effects
Malarone is generally well-tolerated. The most commonly reported side effects are mild GI symptoms: stomach discomfort, nausea, and occasional headache. In clinical studies, patients taking Malarone reported fewer adverse events compared to other antimalarials like mefloquine.
The key advantage: Malarone doesn't cause sun sensitivity. If your trip involves beaches, hiking, or really any time outdoors (so, most trips), this matters.
Doxycycline Side Effects
Doxycycline's biggest drawback for travelers is photosensitivity. It makes your skin significantly more prone to sunburn. If you're headed to a tropical destination, you'll need to be vigilant with sunscreen and sun protection, which can be a real hassle.
Other common side effects include GI upset (taking it with food helps), esophageal irritation (always take it with a full glass of water and don't lie down right after), and yeast infections, which can be particularly inconvenient while traveling.
On the flip side, doxycycline pulls double duty: it also provides some protection against other travel-related infections like leptospirosis and rickettsial diseases. That can be a bonus in certain destinations.
The Post-Travel Catch: 7 Days vs 28 Days
This is the difference that surprises most travelers.
After you leave a malaria zone, Malarone only needs to be taken for 7 more days. Doxycycline requires 28 days (four full weeks) after your last day of exposure.
Why the difference? It comes down to where in the parasite's life cycle each drug works. Malarone is active against the parasite in the liver stage (called "causal prophylaxis"), so it clears the parasite faster. Doxycycline only works once the parasite has moved into the bloodstream, so you need a longer tail to catch any late-emerging parasites.
For short trips (a week-long safari or a 10-day vacation) this can be a significant factor. With Malarone, your total course might be about 2.5 weeks. With doxycycline, that same trip could mean 5+ weeks of daily pills.
Cost: The Budget Breakdown
Let's talk money, because this is often the deciding factor.
Doxycycline is cheaper. The generic is widely available and a full course for a two-week trip (including the 28-day post-travel tail) typically runs $10–30 at most pharmacies.
Generic Malarone (atovaquone-proguanil) has come down significantly in price from the brand-name days, but it's still pricier, typically $30–70 for a two-week trip course. Brand-name Malarone can run significantly higher without insurance or coupons.
If budget is a major constraint and you don't have specific risk factors that make doxycycline a poor choice, it's a perfectly effective option. But consider the full picture: a month of daily pills and sun sensitivity management have their own "costs."

Who Should Choose Malarone?
Malarone tends to be the better fit if:
- You're taking a short trip and don't want to take pills for a month after you're home
- Your trip is outdoors-heavy (safaris, beach destinations, hiking) where sun sensitivity would be a real problem
- You're traveling with children under 8, since doxycycline isn't approved for young kids
- You're prone to yeast infections or have had GI issues with antibiotics before
- You're also traveling to high-altitude destinations where sun exposure is already intensified
Who Should Choose Doxycycline?
Doxycycline makes more sense if:
- Budget is a priority and you want the most affordable option
- You're already taking doxycycline for another condition (like acne)
- Your trip is longer-term: for extended travel, the daily cost difference adds up in Malarone's favor, but adherence to a 28-day post-travel course is easier to manage when you've already built the daily habit
- You want dual protection since doxycycline's broad antibiotic coverage provides some bonus protection against other travel infections
- Sun exposure isn't a major factor in your itinerary
What About Mefloquine (Lariam)?
You might also see mefloquine come up in your research. While it's a valid option (and the only one that's taken weekly instead of daily), it carries a higher risk of neuropsychiatric side effects: vivid dreams, anxiety, mood changes. Most travel medicine physicians, including our team, tend to recommend Malarone or doxycycline first. We'll cover the mefloquine comparison in a separate post.
The Bottom Line
Both Malarone and doxycycline are effective, CDC-recommended antimalarials. Neither is objectively "better." The right choice depends on your trip length, budget, sun exposure, and personal health history.
If you're unsure which is right for your specific trip, that's exactly what we're here for. Wandr Health's physicians review your destination, itinerary, and medical history to recommend the right antimalarial and ship it to your door before you leave.

Frequently Asked Questions
Is Malarone or doxycycline better for Africa? Both are equally recommended by the CDC for sub-Saharan Africa, where chloroquine-resistant malaria is prevalent. The choice comes down to personal factors like budget, trip length, and sun exposure, not destination. If you're doing a safari with lots of outdoor time, Malarone's lack of sun sensitivity is a practical advantage.
Can I drink alcohol while taking malaria medication? Moderate alcohol consumption is generally fine with both Malarone and doxycycline. However, doxycycline can increase stomach irritation, and alcohol can amplify that effect. As with any medication, moderation is wise.
What happens if I miss a dose? Take the missed dose as soon as you remember. If it's almost time for your next dose, skip the missed one and don't double up. Missing doses reduces the effectiveness of malaria prophylaxis, so setting a daily phone alarm is a smart move.
Can I take Malarone or doxycycline if I'm pregnant? Neither is the first choice during pregnancy. Mefloquine is the CDC-recommended antimalarial for pregnant travelers going to areas with chloroquine-resistant malaria. Discuss your options with your physician before traveling.
Do I really need malaria pills? If the CDC recommends prophylaxis for your destination, yes. Malaria kills hundreds of thousands of people annually and remains a serious risk in parts of Africa, South Asia, and Central/South America. Prevention medication, combined with mosquito bite prevention measures, is the most effective way to protect yourself.
