Linzess Cost in 2026: Prices and How to Save
Linzess Cost in 2026: Prices and How to Save
Your gastroenterologist writes the prescription, you walk to the pharmacy counter feeling hopeful, and then the tech reads the number out loud: about $700 for 30 capsules. For a lot of people, that's the moment the Linzess cost turns a treatment that finally works into a monthly budgeting problem.
Linzess does its job well for IBS with constipation and chronic constipation, which is part of why the price stings so much. There's no generic to fall back on, and that single fact shapes nearly everything you'll pay. Here's what Linzess actually costs in 2026, why it's priced the way it is, and the practical ways to spend less.
How much does Linzess cost without insurance?
Without insurance, a 30-capsule supply of Linzess generally lands between $630 and $750, depending on the pharmacy and where you live. The most commonly prescribed strength, 145 mcg, averages around $736 for 30 capsules at full retail.
One detail that surprises people: all three strengths cost about the same. Linzess comes in 72 mcg, 145 mcg, and 290 mcg capsules, and because you take one capsule a day regardless of strength, the per-month price barely changes between them. So moving from 145 mcg to 290 mcg usually won't raise your bill.
Here's how the numbers break down across the avenues most people actually use:
| How you pay | 30-day supply (any strength) | Notes |
|---|---|---|
| Full retail, no discount | $630–$750 | Varies widely by pharmacy |
| Free prescription discount card | ~$250–$300 | Third-party cards like GoodRx or SingleCare |
| Cash-pay through CanAmerica Plus | ~$362 for a 90-day supply (about $121/mo) | Licensed, verified pharmacies |
| Manufacturer WAC (list price) | $282 | What pharmacies pay, not what you pay |
Prices move around, so the figure your pharmacy quotes today may differ from one across town. Calling two or three pharmacies before you fill is one of the easiest ways to avoid overpaying.
Why is Linzess so expensive?
It comes down to one word: exclusivity. Linzess is a guanylate cyclase-C agonist — it pulls fluid into your intestines and speeds up transit — and it's still sold only as a brand-name drug. When a medication has no generic competition, the manufacturer sets the price, and there's nothing pushing it down.
The patent picture is more tangled than most people expect. The original composition-of-matter patent on linaclotide expired in 2025, which would normally open the door to generics. But secondary patents covering the formulation and manufacturing stretch the protection out for years longer.
There's also a gap between the list price and what you actually pay. The wholesale acquisition cost sits around $282 a month, but that's the price pharmacies pay the manufacturer. By the time wholesaler and pharmacy markups are added, the cash price at the register is often more than double that.
When will a generic for Linzess be available?
Not as soon as the 2025 patent expiration might suggest. Under settlement agreements, Teva is set to launch a generic version of the 72 mcg dose on March 31, 2029. Generic versions of the 145 mcg and 290 mcg strengths — the ones most people take — aren't expected until around 2030.
In other words, the generic linaclotide most patients are waiting for is still several years out. Planning your savings strategy around a near-term generic isn't realistic.
Linzess cost with Medicare and insurance
If you have Medicare Part D or a commercial plan, your Linzess cost depends on the formulary tier, your deductible, and whether you've hit the coverage gap. Many plans place Linzess on a higher tier and require prior authorization, meaning your doctor has to document that you've tried other options first.
When a plan covers it well, a monthly copay might run $25 to $100. When it doesn't — or when you're still inside your deductible — you can be exposed to close to the full cash price. That's why some insured patients still end up comparing cash and discount-card prices, which occasionally beat the insurance copay outright.
How to save on Linzess
The good options here aren't complicated, but they do take a few phone calls. A medication this expensive rewards the effort.
Savings tip: Cash prices for the exact same prescription can differ by $200 or more between two pharmacies a mile apart. Before you fill, ask each pharmacy for their cash price — not just what your copay would be — and compare it against a discount card and a cash-pay quote.
A few avenues that consistently help:
Compare pharmacy cash prices. Independent and warehouse-club pharmacies often quote lower cash prices than big chains. It's worth five minutes on the phone.
Use a free prescription discount card. Third-party cards such as GoodRx and SingleCare are free to use and frequently bring a 30-day supply down to roughly $250–$300. You don't need insurance, and you can't combine them with it.
Look at cash-pay sourcing. A cash-pay health network like CanAmerica Plus connects you with licensed, verified pharmacies, which can be a meaningful saving on brand-only drugs like this one — a 90-day supply of Linzess runs about $362, or roughly $121 a month, well below the U.S. retail cash price. Whatever route you choose, confirm the pharmacy is licensed and verified before you buy.
Ask your doctor about a cheaper medication in the same space. This is the big one, and it's covered in the next section.
Cheaper alternatives to Linzess
Linzess isn't the only treatment for IBS-C and chronic idiopathic constipation, and one of the alternatives is dramatically less expensive because it's available as a generic.
Amitiza (lubiprostone) works through a different mechanism but treats the same conditions. Crucially, generic lubiprostone is on the market in the U.S., and it often costs somewhere between $40 and $100 a month — a fraction of Linzess. For many people, that price difference alone is reason enough to ask whether it's a fit.
The other prescription options are still brand-only at U.S. retail, so they won't necessarily save you money there. But through cash-pay sourcing the math shifts: Trulance (plecanatide) runs about $211 for 30 tablets through CanAmerica Plus, and prucalopride — the active ingredient in Motegrity — comes in around $129 for 100 tablets. These matter most if Linzess isn't working for you or causes side effects.
| Medication | Treats | U.S. generic? | Typical monthly cost |
|---|---|---|---|
| Linzess (linaclotide) | IBS-C, CIC | No | $630–$750 retail |
| Trulance (plecanatide) | IBS-C, CIC | No | ~$211 cash-pay |
| Amitiza (lubiprostone) | IBS-C, CIC | Yes | $40–$100 generic |
| Motegrity (prucalopride) | CIC | No | ~$129 cash-pay |
| Ibsrela (tenapanor) | IBS-C | No | $700–$800 retail |
Over-the-counter approaches like polyethylene glycol (MiraLAX) and fiber supplements cost a few dollars and help some people with milder symptoms, though they don't address the abdominal pain side of IBS-C the way prescription options can.
One caveat worth stating plainly: don't switch or stop Linzess on your own. These medications work differently and aren't interchangeable, so any change should go through the prescriber who knows your history.
A quick note on safety
Cost matters, but so does using the drug correctly. Linzess carries a boxed warning — the FDA's most serious — because it can cause severe dehydration in young children and is not for use in anyone under 2 years old.
For adults, the most common side effect is diarrhea, and for some people it's significant. If it becomes severe, stop taking Linzess and call your doctor. Taking it on an empty stomach, at least 30 minutes before the first meal of the day, helps reduce stomach upset.
The bottom line
Linzess is expensive because it's brand-only, and with the meaningful generic still years away, the smartest move is to shop the price actively rather than accept the first number you're quoted. Compare pharmacy cash prices, check a discount card and a cash-pay quote, and have an honest conversation with your doctor about whether generic lubiprostone or another option could work for you. The difference between the worst price and the best one can run several hundred dollars a month.
Frequently asked questions
How much does Linzess cost per month?
Without insurance, expect roughly $630 to $750 for a 30-day supply at full retail. A free discount card usually brings that down to around $250–$300, and pricing is similar across the 72 mcg, 145 mcg, and 290 mcg strengths.
Why is Linzess so expensive?
Because it has no generic competition. As a brand-only medication protected by secondary patents through about 2030, its price isn't being pushed down by lower-cost equivalents the way it would be once generics arrive.
Is there a generic for Linzess?
Not yet. A generic of the 72 mcg dose is scheduled to launch in 2029, with the more commonly used 145 mcg and 290 mcg strengths expected around 2030.
Does Medicare cover Linzess?
Many Medicare Part D plans cover Linzess, but often on a higher tier and with prior authorization. Your actual cost depends on your plan's formulary, your deductible, and whether you've reached the coverage gap, so it's worth checking your specific plan.
What's the cheapest way to get Linzess?
There's no single answer, but comparing pharmacy cash prices, using a free discount card, and checking a cash-pay quote will usually surface the lowest price. If cost is the deciding factor, ask your doctor whether generic lubiprostone is a reasonable alternative.
