Struggling to find Atovaquone/Proguanil (Malarone) at your pharmacy? Learn why this antimalarial is hard to find and what you can do about it in 2026.
If you've been prescribed Atovaquone/Proguanil — sold under the brand name Malarone — for malaria prevention or treatment, you may have run into a frustrating problem: your pharmacy doesn't have it in stock. You're not alone. Many patients across the U.S. are struggling to fill this prescription, especially during peak travel seasons.
In this guide, we'll break down exactly why Atovaquone/Proguanil can be difficult to find, what's driving availability issues in 2026, and what steps you can take to get your medication before your trip.
Atovaquone/Proguanil is a combination antimalarial medication used to prevent and treat malaria caused by Plasmodium falciparum. It's one of the most commonly prescribed antimalarials for travelers heading to regions where malaria is endemic, including parts of Africa, Southeast Asia, and South America.
The brand-name version, Malarone, is manufactured by GlaxoSmithKline (GSK). Generic versions are now widely available from manufacturers like Mylan, Teva, Cipla, and others, which has helped bring costs down significantly. For a deeper dive into how this medication works, check out our guide on how Atovaquone/Proguanil works.
The biggest factor driving availability issues is seasonal demand. Malaria prophylaxis is a travel medication — demand surges during peak travel seasons like summer vacation (June through August) and the winter holiday season (December through January). Pharmacies that don't typically stock Atovaquone/Proguanil may not have it when you need it.
Unlike common medications like blood pressure pills or antibiotics, Atovaquone/Proguanil is a specialty medication that many retail pharmacies don't keep on their shelves year-round. It's not a daily-use medication for most patients — it's taken for short periods before, during, and after travel. This means pharmacies may need to special-order it, which can take several days.
While having multiple generic manufacturers (Mylan, Teva, Cipla, Sun Pharma, Aurobindo, Lupin, and others) generally helps availability, it can also mean that any individual manufacturer's supply may be inconsistent. Your pharmacy may carry one manufacturer's version but not another, and switching between generics can sometimes require a new order.
Global pharmaceutical supply chains remain vulnerable to disruptions. Raw material sourcing, shipping delays, and manufacturing capacity issues can all contribute to temporary stock-outs at the wholesale level.
Some insurance plans require prior authorization for brand-name Malarone, which can delay your ability to pick up the prescription. While generic Atovaquone/Proguanil is usually covered without PA, the process can still slow things down if there's a formulary issue. Learn more about saving money on Atovaquone/Proguanil.
As of early 2026, Atovaquone/Proguanil is not on the FDA's official drug shortage list. The drug has not experienced a significant nationwide shortage in recent years. However, that doesn't mean it's easy to find at every pharmacy — localized stock-outs are common, particularly during high-demand periods.

The single most important step is to get your prescription filled well before your travel date. Don't wait until the week before your trip. Ideally, see your doctor or a travel medicine specialist 4-6 weeks before departure. This gives you time to deal with any availability or insurance issues.
Instead of calling dozens of pharmacies, use MedFinder to check which pharmacies near you have Atovaquone/Proguanil in stock. It saves time and helps you find what you need quickly.
If your regular pharmacy doesn't have it on the shelf, ask them to order it. Most pharmacies can get it from their wholesaler within 1-3 business days.
Larger chain pharmacies and those near international airports or in urban areas may be more likely to stock Atovaquone/Proguanil regularly. Costco, CVS, Walgreens, and Walmart pharmacies are good options to check.
If Atovaquone/Proguanil is truly unavailable, talk to your doctor about alternative antimalarial medications like Doxycycline, Mefloquine, Chloroquine (for sensitive areas), or Tafenoquine (Arakoda).
If you need a prescription quickly, many telehealth services now offer travel medicine consultations. You can often get a prescription for Atovaquone/Proguanil within 24 hours. Learn how to find a doctor who prescribes Atovaquone/Proguanil.
Atovaquone/Proguanil isn't experiencing a formal shortage in 2026, but it can still be hard to find due to seasonal demand, limited pharmacy stocking, and supply chain quirks.
