If you’re planning a trip to a malaria-endemic region, you’ve likely spent time comparing antimalarial medications. For years, travelers have had three main options: atovaquone-proguanil (Malarone), doxycycline, and mefloquine. Now there’s a fourth — and for many travelers, it may be the most convenient choice yet.
Arakoda (tafenoquine) is the first weekly antimalarial pill approved by the FDA for malaria prevention, or chemoprophylaxis. Instead of taking a pill every day, you take one tablet per week while traveling. That shift alone makes Arakoda a game-changer for people who struggle with daily medication schedules — especially on busy, multi-week adventures.
In this guide, we’ll cover everything you need to know about Arakoda: how it works, how it stacks up against other antimalarials, who it’s best suited for, potential side effects, and the critical G6PD test you’ll need before starting. We’ll also explain how you can get an Arakoda prescription quickly through Runway Health’s online consultation.
What Is Arakoda (Tafenoquine)?
Arakoda is the brand name for tafenoquine, an antimalarial drug that belongs to the 8-aminoquinoline class of medications — the same class as primaquine, a drug that has been used to treat malaria for decades. The FDA approved Arakoda in 2018 specifically for the prevention of malaria in adults aged 18 and older.
Unlike older antimalarials that require daily dosing, Arakoda’s long half-life allows for once-weekly dosing during travel. This is a significant advantage, since missed doses are one of the biggest reasons antimalarial prophylaxis fails. Fewer doses means fewer chances to forget.
Tafenoquine is effective against both Plasmodium falciparum and Plasmodium vivax — the two species responsible for the vast majority of malaria cases worldwide. This makes it suitable for travel to virtually any malaria-endemic destination.
How Does Arakoda Work?
As an 8-aminoquinoline, tafenoquine works differently from other antimalarial drugs. It targets multiple stages of the malaria parasite’s life cycle, giving it a broader mechanism of action compared to some alternatives.
Multi-Stage Activity
Most antimalarials primarily target the blood-stage parasites — the stage that causes symptoms. Tafenoquine goes further. It acts against:
- Liver-stage parasites (pre-erythrocytic stage) — It kills parasites in the liver before they can enter the bloodstream and cause infection. This is its primary prophylactic action.
- Blood-stage parasites (erythrocytic stage) — It also has activity against parasites circulating in red blood cells.
- Dormant liver-stage parasites (hypnozoites) — For P. vivax infections, tafenoquine can eliminate dormant parasites that would otherwise cause relapses weeks or months later.
This multi-stage activity is part of what makes tafenoquine unique among antimalarials and particularly valuable for travelers visiting areas where P. vivax is common, such as parts of India and Southeast Asia.
The Long Half-Life Advantage
Tafenoquine has a remarkably long half-life of approximately 14 to 28 days. This is what makes weekly dosing possible. By comparison, atovaquone-proguanil (Malarone) has a half-life of about 2 to 3 days, requiring daily dosing. The long half-life also means the drug continues to provide protection for an extended period after the last dose — a built-in safety net if you’re slightly late taking your final doses.
Arakoda Dosing Schedule
The Arakoda dosing regimen is straightforward and consists of three phases:
1. Loading Dose (Before Travel)
Take 200 mg (one tablet) once daily for 3 consecutive days, starting 3 days before you arrive in the malaria-endemic area. This loading phase builds up protective drug levels in your body before you’re exposed to malaria-carrying mosquitoes.
2. Maintenance Dose (During Travel)
Take 200 mg (one tablet) once weekly while you’re in the malaria-endemic area. Take it on the same day each week, starting 7 days after the last loading dose.
3. Terminal Dose (After Travel)
Take 200 mg (one tablet) once, 7 days after your last maintenance dose. This final dose helps eliminate any parasites that may have entered your liver during the last days of your trip.
Example: If you depart on a Wednesday and will be in a malaria zone for 3 weeks, you’d take your loading doses on Sunday, Monday, and Tuesday before departure. Then take one tablet each following Sunday while abroad. Take one final tablet the Sunday after you return home.
Compare that to Malarone’s schedule (one pill daily starting 1–2 days before, every day during, and for 7 days after travel) or doxycycline (daily starting 1–2 days before, daily during, and for 28 days after), and Arakoda’s simplicity becomes clear — especially for trips lasting several weeks or more.
Arakoda vs. Other Antimalarials: A Head-to-Head Comparison
Choosing the right antimalarial depends on your destination, trip length, health history, and personal preferences. Here’s how Arakoda compares to the three other commonly prescribed options. For deeper comparisons, see our articles on doxycycline vs. Malarone and Malarone vs. mefloquine.
Arakoda vs. Malarone (Atovaquone-Proguanil)
Malarone is the most commonly prescribed antimalarial for travelers and is known for being well-tolerated with relatively few side effects. However, it requires daily dosing — one pill per day starting 1–2 days before travel, every day during, and for 7 days after leaving the malaria zone.
- Dosing: Malarone is daily; Arakoda is weekly. For a 3-week trip, that’s roughly 30+ Malarone pills vs. about 7 Arakoda pills.
- Cost: Malarone can be expensive for long trips because of the daily dosing. Arakoda’s fewer pills can be more cost-effective for extended travel.
- Tolerability: Both are generally well-tolerated. Malarone may cause nausea and headaches; Arakoda may cause similar GI symptoms plus vivid dreams.
- Post-travel dosing: Malarone requires 7 days of post-travel dosing; Arakoda requires just one final dose.
Best for: Arakoda is the better choice if you want fewer pills, especially on longer trips. Malarone may be preferred if you want to avoid the G6PD test requirement or need a pediatric option (Arakoda is only approved for adults 18+).
Arakoda vs. Doxycycline
Doxycycline is an antibiotic that doubles as an antimalarial. It’s the most affordable option and is widely available. However, it comes with daily dosing and a notably long post-travel regimen.
- Dosing: Doxycycline is daily, starting 1–2 days before travel, every day during, and for 28 days after leaving the malaria area. Arakoda’s post-travel dosing is just one tablet.
- Side effects: Doxycycline commonly causes sun sensitivity (photosensitivity), which can be particularly problematic in tropical climates. It can also cause esophageal irritation and yeast infections. Arakoda does not cause photosensitivity.
- Cost: Doxycycline is the cheapest antimalarial. Arakoda is more expensive per pill but requires far fewer pills overall.
Best for: Arakoda is the better choice if you’ll be spending a lot of time outdoors in the sun, want to avoid 28 days of post-travel pills, or tend to forget daily medications. Doxycycline is the budget-friendly option for travelers who don’t mind the daily schedule.
Arakoda vs. Mefloquine (Lariam)
Mefloquine is another weekly antimalarial, so its dosing schedule is similar to Arakoda’s. However, mefloquine has a well-documented history of neuropsychiatric side effects.
- Dosing: Both are weekly during travel. However, mefloquine requires starting 2–3 weeks before departure (vs. Arakoda’s 3-day loading phase), and mefloquine must be continued for 4 weeks after leaving the malaria zone (vs. Arakoda’s single post-travel dose).
- Side effects: Mefloquine can cause vivid dreams, anxiety, depression, dizziness, and in rare cases, psychosis and seizures. The FDA has issued a boxed warning about these neuropsychiatric effects. Arakoda may cause vivid dreams and dizziness but does not carry the same level of neuropsychiatric concern.
- Pre-travel lead time: Mefloquine’s 2–3 week lead time can be inconvenient for last-minute travelers. Arakoda only needs 3 days.
Best for: Arakoda is the better weekly option for most travelers due to its shorter lead time, shorter post-travel regimen, and milder side-effect profile. Mefloquine may be considered when Arakoda isn’t available or when cost is a primary concern.
Who Should Consider Arakoda?
Arakoda may be an excellent fit if you:
- Are an adult (18+) traveling to a malaria-endemic area — Arakoda is only approved for adults. Pediatric travelers will need a different option like Malarone.
- Are taking a longer trip — The weekly dosing schedule makes Arakoda especially practical for trips lasting 2 weeks or more. Over a multi-month trip, the difference between daily and weekly dosing adds up significantly.
- Struggle with daily medication adherence — If you know you’re likely to forget a daily pill, the weekly schedule reduces that risk substantially.
- Spend a lot of time outdoors — Unlike doxycycline, Arakoda doesn’t cause photosensitivity, making it a smart choice for safaris, trekking, and beach travel.
- Want a short post-travel regimen — Just one pill after you return home, compared to 7 days (Malarone), 28 days (doxycycline), or 4 weeks (mefloquine).
- Plan last-minute travel — Arakoda’s 3-day loading phase means you can start later than mefloquine (which needs 2–3 weeks of lead time).
Whether you’re heading to Nigeria, Uganda, or India, Arakoda can provide effective malaria protection with the convenience of weekly dosing. Each of these destinations carries significant malaria risk, and prophylaxis is strongly recommended by the CDC.
Who Should NOT Take Arakoda?
Arakoda is not appropriate for everyone. Important contraindications include:
- G6PD deficiency — This is the most critical contraindication. People with glucose-6-phosphate dehydrogenase (G6PD) deficiency can experience hemolytic anemia (dangerous destruction of red blood cells) when taking tafenoquine. A G6PD test is mandatory before starting Arakoda. More on this below.
- Pregnancy and breastfeeding — Arakoda is not recommended during pregnancy or while breastfeeding a G6PD-deficient infant, as the drug may pass to the baby and cause hemolytic anemia.
- Known psychotic disorders — Patients with a history of psychotic disorders should not take tafenoquine.
- Hypersensitivity — Anyone with a known allergy to tafenoquine, other 8-aminoquinolines, or any component of the formulation should not take it.
- Children under 18 — Arakoda is not approved for pediatric use.
The G6PD Test: Why It’s Required and What to Expect
Before prescribing Arakoda, your healthcare provider must confirm that you do not have G6PD deficiency. This is not optional — it’s a safety requirement mandated by the FDA.
What Is G6PD Deficiency?
Glucose-6-phosphate dehydrogenase (G6PD) is an enzyme that protects red blood cells from oxidative damage. People who lack sufficient G6PD — a condition called G6PD deficiency — are vulnerable to hemolytic anemia when exposed to certain medications, including tafenoquine and primaquine.
G6PD deficiency is the most common enzyme deficiency worldwide, affecting an estimated 400 million people. It’s more prevalent in people of African, Mediterranean, Middle Eastern, and Southeast Asian descent — populations that often overlap with those traveling to malaria-endemic regions.
How the G6PD Test Works
The G6PD test is a simple blood test that measures the enzyme level in your red blood cells. It can be performed through a standard blood draw at a lab, and results are typically available within a few days. Some point-of-care rapid tests can provide results even faster.
If your G6PD levels are normal, you can safely take Arakoda. If the test reveals G6PD deficiency, your provider will recommend an alternative antimalarial such as atovaquone-proguanil (Malarone) or doxycycline, neither of which carry G6PD-related risks.
Planning Ahead
Because the G6PD test is required before you can start Arakoda, it’s important to begin the prescription process early — ideally at least 2–3 weeks before your departure date. This allows time for the blood test, results, and prescription to be processed. Through Runway Health’s streamlined process, you can get started quickly with an online consultation.
Side Effects of Arakoda
Like all medications, Arakoda can cause side effects. In clinical trials, the most commonly reported side effects were generally mild to moderate and included:
- Gastrointestinal symptoms — Nausea, vomiting, diarrhea, and abdominal pain
- Headache — One of the more frequently reported effects
- Dizziness — Usually mild and transient
- Vivid or abnormal dreams — Reported by some users, similar to mefloquine but generally less intense
- Back pain — Occasionally reported
- Elevated liver enzymes — Usually without clinical significance, but your provider may monitor this
Rare but Serious Side Effects
In rare cases, tafenoquine has been associated with:
- Hemolytic anemia — Almost exclusively in patients with undiagnosed G6PD deficiency, which is why the screening test is mandatory
- Methemoglobinemia — An elevation in methemoglobin levels, which reduces the blood’s oxygen-carrying capacity. This is typically mild but should be monitored
- Psychiatric effects — Rare reports of anxiety, insomnia, or mood changes. Unlike mefloquine, tafenoquine does not carry a boxed warning for neuropsychiatric effects
- Hypersensitivity reactions — Allergic reactions including rash and angioedema, though uncommon
It’s important to note that because of tafenoquine’s long half-life, if you do experience a side effect, it may take longer to resolve after discontinuing the medication. This is something to discuss with your healthcare provider before starting treatment.
Arakoda for Different Destinations
Arakoda is effective for travel to any malaria-endemic region. Here are some high-risk destinations where travelers frequently need antimalarial protection:
Nigeria
Nigeria accounts for roughly 27% of all global malaria cases, making it the country with the highest malaria burden in the world. Malaria transmission occurs year-round throughout the country, including in urban areas like Lagos and Abuja. The CDC recommends antimalarial prophylaxis for all travelers to Nigeria. Read our full guide: Malaria Risk in Nigeria — The Safest Approach for Travelers.
Uganda
Uganda is another high-transmission country where malaria is endemic across the entire nation. Travelers visiting national parks for gorilla trekking, safari, or volunteer work are at significant risk. The rural nature of many popular destinations increases mosquito exposure.

India
India presents a more variable malaria risk depending on the region and season. Cities like New Delhi and Mumbai carry risk, particularly during and after the monsoon season. Rural areas in central and eastern India see the highest transmission rates. India also has significant P. vivax malaria, making Arakoda’s activity against hypnozoites especially relevant.

Frequently Asked Questions
Q: Is Arakoda available as a generic?
As of now, Arakoda (tafenoquine) is available only as a brand-name medication. There is no generic version currently on the market. However, the weekly dosing means fewer total pills are needed compared to daily alternatives, which can help offset the cost.
Q: Can I take Arakoda if I’m already in a malaria zone?
Arakoda is intended to be started before entering a malaria-endemic area (the 3-day loading dose should be completed before arrival). If you’re already in a malaria zone without prophylaxis, consult a healthcare provider immediately about your options.
Q: How does Arakoda compare to the malaria vaccine?
The malaria vaccine (RTS,S/Mosquirix) is currently recommended primarily for young children in endemic areas and is not widely available to adult travelers. For travel prophylaxis, antimalarial medications like Arakoda remain the standard of care.
Q: Can I drink alcohol while taking Arakoda?
There are no specific contraindications regarding alcohol and tafenoquine. However, both alcohol and Arakoda can cause dizziness and GI symptoms, so moderation is advisable. Consult your healthcare provider if you have concerns.
Q: What if I forget a weekly dose?
If you miss a weekly dose, take it as soon as you remember and then resume your regular weekly schedule. Tafenoquine’s long half-life provides some buffer, but consistent dosing is important for reliable protection. For tips on staying on track, see our article on what to do if you forget your malaria tablets.
Q: Are malaria pills really worth taking?
Absolutely. Malaria can be a life-threatening illness, and prophylactic medication dramatically reduces your risk of infection. For a detailed breakdown, read our guide: Are Malaria Pills Worth It for Travel? (Pros and Cons).
The Bottom Line: Is Arakoda Right for You?
Arakoda represents a meaningful step forward in malaria prevention for travelers. Its weekly dosing, short post-travel regimen, broad-spectrum activity, and lack of photosensitivity make it an appealing option — particularly for longer trips, outdoor-heavy itineraries, and travelers who value convenience.
The main considerations before choosing Arakoda are the required G6PD test, its limitation to adults 18 and older, and the fact that side effects (if they occur) may linger longer due to the drug’s long half-life. For most healthy adult travelers, these are minor trade-offs for the significant convenience gains.
If you’re planning travel to a malaria-endemic destination and want to find out whether Arakoda is right for you, Runway Health makes it easy. Start with a quick online consultation, and a licensed provider will help you choose the best antimalarial for your specific trip and health profile.
