Primaquine Shortage Update: What Patients Need to Know in 2026

If you've been prescribed primaquine and can't find it at your local pharmacy, you might be wondering whether there's an active shortage. Here's what patients need to know about primaquine availability in 2026 — including why it can still be hard to find even when no official shortage exists.

Is There an Active Primaquine Shortage in 2026?

As of 2026, primaquine is not listed as an active nationwide shortage on the FDA Drug Shortage Database or ASHP (American Society of Health-System Pharmacists) shortage list. The generic product — primaquine phosphate 26.3 mg tablets — is commercially available from multiple manufacturers and suppliers.

However, "not in shortage" does not mean "easy to find." The reality for most US patients is that primaquine is a niche, low-demand medication that most retail pharmacies simply don't stock as part of their standard inventory. This creates what might be called a structural availability problem — the drug exists in the supply chain, but it's not on the shelf at your corner pharmacy.

Primaquine's History of Supply Vulnerabilities

Primaquine has experienced periods of constrained supply in the past, which helps explain why some patients and providers approach it with an attitude of scarcity even in non-shortage periods. Several factors have historically contributed to supply pressure:

Limited manufacturer base. Primaquine is not a high-revenue drug for pharmaceutical companies, given its niche use in the US market. Only a small number of manufacturers produce FDA-approved primaquine for US distribution, which means any production disruption — a facility issue, raw material supply problem, or regulatory action — can quickly affect national availability.

CDC stockpile discontinuation. The CDC previously distributed primaquine from its own drug service stockpile to help meet demand, particularly during times of supply stress. This service was discontinued, placing the full burden on the commercial market — which sometimes struggles to meet sudden demand spikes, such as during malaria outbreaks among returning travelers.

Global supply chain pressures. Like many older generic drugs, primaquine's active pharmaceutical ingredients (APIs) are largely sourced from overseas manufacturers. Supply chain disruptions — geopolitical, logistical, or quality-related — can create upstream shortages that ripple to patients.

What Drives the "Local" Shortage Experience?

Even without a national shortage, patients often experience what feels like a shortage at the local level. Here's why:

Low stocking at retail pharmacies. Most retail pharmacies — CVS, Walgreens, Rite Aid, and independent stores — don't stock primaquine routinely because it has very low prescription volume in the US. Malaria is not endemic here, and most primaquine prescriptions come from travel medicine clinics or infectious disease departments.

Seasonal demand spikes. Demand for primaquine — particularly for travel prophylaxis — peaks before summer travel season and during outbreak periods. Pharmacies that don't stock it year-round may struggle to meet sudden demand.

G6PD testing requirement. The required G6PD screening before dispensing adds a step that some pharmacies aren't set up to support, which may further discourage routine stocking.

What Can Patients Do Right Now?

If you've been prescribed primaquine and are having trouble filling it, here are the most effective immediate actions:

Use medfinder to locate nearby pharmacies with stock. medfinder calls pharmacies in your area on your behalf, checking which ones have primaquine available and can fill your prescription. This is much faster than calling pharmacies yourself.

Contact hospital and specialty pharmacies. Hospital outpatient pharmacies and specialty pharmacies are more likely to carry primaquine than standard retail chains. If you're near an academic medical center, start there.

Ask your pharmacy to special-order it. Most pharmacies can order primaquine from their wholesale supplier in 1-3 business days if you have a prescription in hand.

Ask your doctor about alternatives if truly necessary. If all else fails, tafenoquine (Krintafel) is the only other option for radical cure. For prophylaxis, atovaquone-proguanil, doxycycline, and mefloquine are available alternatives (though none prevent relapse from P. vivax hypnozoites).
