Linzess Coupons & Prices

Looking for a Linzess coupon? Linzess (linaclotide) is a prescription capsule approved for irritable bowel syndrome with constipation (IBS-C) in adults and in children 7 years and older, chronic idiopathic constipation (CIC) in adults, and functional constipation in children 2 to 17 years old. The FDA approved the first generic linaclotide capsules (Mylan Pharmaceuticals, 145 mcg and 290 mcg) in February 2026, but an approval is not the same thing as a bottle on the shelf: retail availability has been limited and inconsistent, and many people are still handed the brand at the counter. Ask your pharmacist whether a generic can be filled for your strength, and compare that against the cash price here. Enter your ZIP code above to see today's Rx.com cash price at pharmacies near you, then show the free coupon at the counter. It is not insurance, and you can use it whether you are uninsured, on Medicare, or simply paying cash because your plan will not cover the prescription.

What is Linzess and how does it work?

Linzess is the US brand name for linaclotide (sold as Constella in Europe and Canada). It belongs to a drug class called guanylate cyclase-C (GC-C) agonists, a type of peripherally acting gut secretagogue. In plain terms, it works inside the intestine rather than throughout the body: it increases fluid in the bowel so stool moves more easily, and it can calm the pain signals that come with IBS-C. Because it is not meaningfully absorbed into the bloodstream at recommended doses, drug interactions are minimal.

The FDA-approved uses of the capsules are IBS-C in adults (290 mcg once daily), IBS-C in children 7 years and older (145 mcg once daily), chronic idiopathic constipation in adults (145 mcg once daily, with 72 mcg an option for some patients), and functional constipation in children 2 to 17 years of age (72 mcg once daily). The pediatric IBS-C indication was added in November 2025, and the functional constipation indication was expanded down to age 2 in May 2026. Linzess is taken once a day on an empty stomach, at least 30 minutes before the first meal of the day; for children who cannot swallow the capsule, the label allows it to be opened and given in applesauce or water. It relieves symptoms but does not cure the underlying condition, and the full benefit can take a week or more.

Linzess cost: manufacturer savings card vs. the Rx.com cash coupon

The manufacturer runs an official Linzess savings program, which you can find on the manufacturer's own Linzess website. Programs like this are generally limited to people with commercial (employer or marketplace) insurance. If you have Medicare, Medicaid, TRICARE, or any other government drug benefit, you typically are not eligible, and people with no insurance at all are usually excluded too. Eligibility rules, benefit limits and expiration terms vary and change, so read the manufacturer's current terms before you count on it. The manufacturer also points patients toward patient-assistance and support resources for those who cannot afford their prescription; those programs have their own income and coverage requirements.

The Rx.com coupon is different. It is a free cash-discount coupon, not insurance and not tied to any insurance status. It is useful in the exact situations where a manufacturer card falls short: you are uninsured, you are on Medicare, your plan denied or excluded the drug, or the pharmacy declined the manufacturer card. You cannot stack a cash coupon with your insurance on the same fill, so it is worth comparing both. Enter your ZIP above to see today's price at pharmacies near you, then bring the coupon to the counter. Prices move, and they can differ noticeably from one pharmacy to the next on the same block, so it pays to check before you fill — and if your pharmacy can source generic linaclotide, ask what that would cost you as well, since neither the brand nor a generic is automatically the cheaper option for every person.

Is there a generic? Alternatives and how they compare

Yes and no, and the distinction matters at the counter. The FDA approved the first generic linaclotide capsules (Mylan Pharmaceuticals, 145 mcg and 290 mcg) on February 10, 2026. Approval, however, only means a product may be sold; it does not guarantee your pharmacy can order it. Reports on whether that generic is actually stocked at retail have been mixed, and under the patent settlement covering linaclotide, another company's licensed 72 mcg generic is not scheduled to enter until March 31, 2029 — so the 72 mcg strength used for children is still a brand fill. The practical move is to ask your pharmacist two questions: can you get generic linaclotide in my strength, and what would each one cost me today? Then compare that against the cash price on this page. If cost is still the sticking point, it is reasonable to ask your prescriber whether a different prescription option is medically appropriate for you.

• Trulance (plecanatide) — another guanylate cyclase-C agonist, approved for IBS-C and chronic idiopathic constipation in adults. Closest mechanism to Linzess, taken once daily with or without food.
• Amitiza (lubiprostone) — a chloride-channel activator that also draws fluid into the bowel; taken twice daily with food and water.
• Ibsrela (tenapanor) — an NHE3 inhibitor for IBS-C in adults, taken twice daily.
• Motegrity (prucalopride) — a 5-HT4 agonist that speeds up bowel motility, approved for chronic idiopathic constipation in adults.
• Viberzi (eluxadoline) — worth knowing about only to avoid confusion: it treats IBS with diarrhea, the opposite problem, and is not an alternative to Linzess. It is also a Schedule IV controlled substance, which brings its own prescribing and refill rules.

Which of these is right depends on your diagnosis, other health conditions, and how you responded to earlier treatments. That is a conversation for your prescriber, not a coupon comparison.

Safety: what to know before you take Linzess

Linzess carries a boxed warning for the risk of serious dehydration in young children. It is contraindicated in children under 2 years of age — in neonatal mice, a single dose comparable to a clinically relevant adult dose caused deaths from dehydration. Linzess is also contraindicated in anyone with a known or suspected mechanical blockage of the gastrointestinal tract. In children, the drug is approved only for the uses on the current label: functional constipation from age 2, and IBS-C from age 7. Safety and effectiveness have not been established for IBS-C in children under 7, or for chronic idiopathic constipation in children at all, and no one under 2 should receive it.

Diarrhea is both the most common and the most serious side effect in adults, reported by up to about 20% of people, and it can begin within the first two weeks of treatment. If diarrhea becomes severe, stop the drug, rehydrate, and contact your prescriber right away — this is especially important for children, who dehydrate faster than adults. Other common effects include abdominal pain, gas, bloating, and abdominal distension. Taking the capsule on an empty stomach, at least 30 minutes before your first meal, is part of the label instructions. This page is general information, not medical advice — talk with your doctor or pharmacist about whether Linzess is right for you or your child, and report any troubling symptoms.
