Almost everyone knows azithromycin by its packaging rather than its name. The Z-Pak is a small cardboard card of six tablets, and it is one of the most recognizable objects in American medicine. It is also, at wholesale, one of the cheapest: a pharmacy buys the whole six-tablet course for about $1.61.
What you pay depends on which form gets dispensed. The same molecule sells as the six-tablet pack, as loose 500 mg tablets, as a single-dose gram of powder in a foil packet, and as a cherry-flavored liquid for kids, and the price spread across those four is wider than most people expect. This guide prices all of them using figures read on September 3, 2026, plus what happened to the brand. What treatment is appropriate is a clinician’s call; everything here is about the money.
What Does Azithromycin Cost Without Insurance?
Three price layers apply. CMS publishes the National Average Drug Acquisition Cost (NADAC), which is what pharmacies pay wholesalers, effective August 19, 2026 for the generic rows below. Cost Plus Drugs publishes a fixed mail-order price. Drugs.com publishes retail cash prices. Every cell names its source, and where the low figure in a row is an acquisition benchmark rather than something you can walk in and buy, it says so.
| Fill | Low | Average | High |
|---|---|---|---|
| Generic Z-Pak, 6 x 250 mg tablets | $1.61 pharmacy acquisition (NADAC $0.26759/tablet) | $5.84 mail order (Cost Plus Drugs) | $10.44 retail cash (Drugs.com, range starts $7.48) |
| Generic 250 mg, 18 tablets (3 packs) | $4.82 pharmacy acquisition (NADAC) | $12.17 retail cash (Drugs.com) | $15.73 retail cash (Drugs.com) |
| Generic 500 mg, 3 tablets (Tri-Pak equivalent) | $1.68 pharmacy acquisition (NADAC $0.56045/tablet) | $6.13 mail order (Cost Plus Drugs) | $10.20 retail cash (Drugs.com, range starts $8.14) |
| Generic 500 mg, 30 tablets | $12.00 mail order (Cost Plus Drugs) | $16.81 pharmacy acquisition (NADAC) | $31.79 retail cash (Drugs.com, range starts $23.11) |
| Generic 1 gram oral powder packet, single dose | $17.01 pharmacy acquisition (NADAC, effective Feb 19, 2025) | no retail cash price published (Drugs.com lists none) | no brand version marketed (FDA shortage database) |
| Generic suspension 200 mg/5 mL, 15 mL bottle | $4.47 pharmacy acquisition (NADAC $0.29818/mL) | $9.15 retail cash (Drugs.com) | $56.62 brand Zithromax (Drugs.com) |
| Generic suspension 200 mg/5 mL, 30 mL bottle | $6.29 pharmacy acquisition (NADAC $0.20952/mL) | $14.04 retail cash (Drugs.com) | $31.65 brand Zithromax (Drugs.com) |
| Brand Zithromax, 250 mg tablets | $12.40 per 6 tablets, pharmacy acquisition (NADAC $2.06704/tablet, Aug 20, 2025) | $14.80 per 6 tablets at the published $2.47/tablet rate (Drugs.com) | $71.03 per 30 tablets (Drugs.com) |
Two things in that table are worth pausing on. First, the 30-count of 500 mg tablets is the one row where Cost Plus Drugs undercuts the national acquisition benchmark, selling for $12.00 what NADAC says the average pharmacy pays $16.81 to buy. Second, the brand NADAC row is a year old (August 20, 2025) while every generic row is current to August 19, 2026, so treat the brand figures as approximate.
Cost Plus Drugs shows its arithmetic on the page: manufacturing cost, a 15% markup, a $5.00 pharmacy labeling fee, and a separate $5.25 standard shipping charge at checkout. So the $5.84 six-tablet pack is really $11.09 delivered if it is the only thing in the order, which erases most of its advantage over a $7.48 retail fill. Mail order pays off when you are buying more than one prescription at a time, or filling the 30-count.
What Drives the Price
The form, more than the dose. The starkest number in this guide is the 1 gram single-dose packet. CMS prices it at $17.01328 per packet while two 500 mg tablets carrying the same gram cost $1.12 at acquisition. That is roughly a 15x premium for the convenience of a foil sachet. CDC’s 2021 STI Treatment Guidelines list azithromycin 1 gram orally in a single dose as an alternative regimen for chlamydial infection in adolescents and adults, with doxycycline as the recommended first-line regimen, and as the recommended regimen during pregnancy. Which product a prescriber writes is their decision, but if the packet is the plan, it is worth knowing that the tablets exist and cost a fraction as much.
Brand versus generic, while the brand lasts. Pfizer told FDA on April 9, 2026 that it is discontinuing manufacture of Zithromax 250 mg and 500 mg tablets, and the FDA drug shortage database now lists both as “To Be Discontinued,” with the reason given as discontinuation of the manufacture of the drug. The Zithromax IV presentation was posted the same way on January 20, 2026 and the Hospira azithromycin injection in September 2025. Practically, the brand comparison is fading; generics from Teva, Sandoz and others carry the market.
Pack size. Drugs.com prices the generic 250 mg tablet at $1.25 to $1.74 each in a six-count and $0.68 to $0.87 each in an 18-count, so three cartons bought together run $12.17 to $15.73 instead of roughly $22 to $31 bought one at a time. Dispensing fees are per fill, not per tablet.
Liquid versus tablets. The pediatric suspension is priced by the bottle, and the per-milliliter acquisition cost falls as the bottle grows: $0.29818 for the 15 mL, $0.23128 for the 22.5 mL and $0.20952 for the 30 mL of the 200 mg/5 mL strength. Retail follows the same curve, $9.15 to $14.04 across those three bottles. The 100 mg/5 mL strength is more expensive per milliliter at $0.39009 because you need more of it.
Where you fill it. Retail cash prices for the same six tablets spanned $7.48 to $10.44 in Drugs.com’s own data, a 40% swing across pharmacies for an identical product. Calling two pharmacies is worth about three dollars here, which matters less than it does on an expensive drug but still tells you how loose the pricing is.
Cash Price vs. Insurance
For a drug this cheap, running an insurance claim is often the more expensive path. A typical generic copay of $10 to $15 is above the $5.84 mail-order price and inside the retail cash range, and if you are in a deductible phase you pay the plan’s full contracted rate, which is frequently higher than the posted cash price on old generics.
Ask the pharmacist for both quotes before the claim goes through. They are allowed to tell you, and on a six-tablet antibiotic the cash-versus-claim question takes about thirty seconds to resolve. Our comparison of GoodRx vs. SingleCare covers how the free discount cards work at the counter and when they beat both cash and insurance.
Where insurance genuinely matters is the visit that produces the prescription, not the prescription itself. A cash urgent care visit or a telehealth consult will usually cost ten to thirty times what the antibiotic does.
How to Pay Less
Ask what form is being written before it is sent. The gap between the 1 gram packet and 500 mg tablets is the biggest single dollar difference available on this drug. Similarly, if a child can swallow tablets, tablets cost less than the suspension. These are clinical decisions, but cost is a legitimate input and prescribers generally want to hear about it.
Price the visit, not just the drug. The prescription is $6 to $10; the encounter that produced it may be $100 to $250. See our urgent care cost guide and doctor visit cost guide for cash ranges, and check any quoted price against our fair price tool.
Use a free or sliding-scale clinic when you can. Federally qualified health centers charge on an income-based sliding scale and many run 340B pharmacies where common generics are near-free. Start with our guide to free clinics and sliding-scale care. If the prescription follows an STI test, the same clinics often provide the testing at no or reduced cost; see STD testing costs without insurance.
Combine mail-order fills. Cost Plus Drugs’ $5.25 shipping is per order, not per prescription. If someone in the household already fills a maintenance drug there, adding the antibiotic costs only the $5.84.
Do not drive to Walmart expecting $4. The Walmart Prescription Program document effective March 24, 2025 contains no azithromycin and no antibiotics of any kind at any tier. The program is built around chronic conditions like blood pressure, diabetes and cholesterol. Verified against the program document itself, not the web page summary.
If the bill is already in collections, that is a different fight. A pharmacy charge rarely lands there, but the associated visit or facility bill does. Our guides to negotiating medical bills and medical bills in collections cover the options.
The Bottom Line
Generic azithromycin is one of the cheapest prescriptions in the pharmacy, and the realistic cash range for the classic Z-Pak is $5.84 to $10.44 depending on where you fill it. The 500 mg tablets and the pediatric suspension land in the same neighborhood, between $6 and $32 depending on quantity. The one form to ask about is the 1 gram single-dose packet, which costs a pharmacy roughly fifteen times what the equivalent tablets cost.
Brand Zithromax is on its way out per FDA’s April 2026 discontinuation postings, so the brand-versus-generic decision that dominates most drug pricing barely exists here. For related pricing, see our guides to valacyclovir and antibiotics without insurance.
