Tysabri Coupons & Prices

Looking for a Tysabri coupon? Tysabri (natalizumab) is a brand-name, once-monthly IV infusion used to treat relapsing forms of multiple sclerosis and moderate-to-severe Crohn's disease. Because it is given in a clinic or infusion center and has no generic, the price can be high — so an Rx.com cash coupon can help lower what you pay out of pocket when you do not have coverage or your insurance falls short.

What Tysabri is and how it works

Tysabri (natalizumab) is a monoclonal antibody classified as an integrin receptor antagonist — specifically an alpha-4 integrin inhibitor. It is a disease-modifying therapy that works by blocking certain immune cells from crossing into the brain, spinal cord, and gut, which helps reduce the inflammation that drives disease activity. It is FDA-approved for relapsing forms of multiple sclerosis (MS) in adults — including clinically isolated syndrome, relapsing-remitting disease, and active secondary progressive disease — and for moderate-to-severe active Crohn's disease in adults who have not responded well to, or cannot tolerate, conventional therapies and TNF-alpha inhibitors.

Tysabri is given as a once-monthly intravenous (IV) infusion by a healthcare provider. Because of its safety profile, it is generally used on its own (as monotherapy) rather than combined with other immunosuppressants or TNF inhibitors. This is general information, not medical advice — your provider decides whether Tysabri is right for you.

Tysabri cost: manufacturer savings card vs. Rx.com cash coupon

Because Tysabri is a brand-name biologic infusion with no generic, cost is a real concern. The manufacturer, Biogen, offers an official copay savings program (the Biogen Copay Program, described on the Tysabri website) for eligible patients. Like most drugmaker copay cards, it is generally limited to people with commercial (private) insurance and is not available to those with Medicare, Medicaid, or other government coverage, and its terms and eligibility can vary — check the program's official details.

If you are uninsured, have Medicare, or the manufacturer card is declined or does not apply to you, an Rx.com cash coupon is a straightforward alternative you can use instead. Biogen also runs patient-assistance support for qualifying patients who cannot afford their medication, which may be worth asking about. To compare your options, enter your ZIP above to see today's price and present the coupon at the pharmacy or infusion provider.

Alternatives and related MS therapies

Tysabri now has an approved biosimilar, natalizumab-sztn, sold as Tyruko — the first biosimilar approved to treat multiple sclerosis. Talk with your provider about whether a biosimilar is an option for you.

There are also several other disease-modifying therapies for relapsing MS. Depending on your situation, your provider may discuss infused or injected options like Ocrevus and Kesimpta, or oral therapies such as Tecfidera, Gilenya, and Vumerity. These work differently and have their own benefits and risks, so the choice is individual — do not switch or stop treatment without your provider's guidance.

Safety and the TOUCH Prescribing Program

Tysabri carries an FDA Boxed Warning for an increased risk of progressive multifocal leukoencephalopathy (PML), a rare but serious brain infection caused by the JC virus that can lead to severe disability or death. Risk is higher with the presence and level of anti-JC virus antibodies, longer treatment duration (especially beyond two years), and prior use of immunosuppressant medicines. Because of this, Tysabri is available only through a restricted program called the TOUCH Prescribing Program (a REMS), which monitors patients and periodically tests for anti-JCV antibodies.

Other risks include serious infusion (hypersensitivity) reactions, liver injury, herpes brain and spinal-cord infections, a higher chance of other infections, and immune reconstitution inflammatory syndrome (IRIS) after stopping. Common side effects can include headache, fatigue, joint pain, urinary tract infection, lower respiratory infection, and depression. This is not a complete list — talk with your provider about the risks and report any new or worsening symptoms right away.
