Apply for Sabril (Vigabatrin) Copay Assistance

Vigabatrin copay assistance means outside financial help that can lower what you pay for Sabril or generic vigabatrin. Depending on your insurance, that help may come from a manufacturer copay program or a grant from an independent nonprofit foundation.*

QuickRx Specialty Pharmacy does the legwork for you. Our patient navigators check your insurance, look for the options you may qualify for, prepare and submit the applications on your behalf, and keep track of renewals, at no cost to you.*

To get started, call QuickRx at (917) 830-2525 or complete the form on this page.

*Eligibility, benefit amounts and availability are set by each manufacturer or foundation, not by QuickRx. Not all patients qualify, and programs may change or close without notice. QuickRx does not issue copay cards; we apply on your behalf.

Some manufacturers offer copay programs for patients with commercial insurance, and the options can differ between Sabril and the other brands and generic versions of vigabatrin. Eligible patients may pay $0.*

QuickRx checks which programs match the version of vigabatrin you are prescribed and applies on your behalf. Call (917) 830-2525.

Each program sets its own rules. Manufacturer copay programs are generally limited to patients with commercial or private insurance, and generally cannot be used by patients whose prescription is paid for by Medicare, Medicaid or other federal health care programs.

Patients with Medicare or other government insurance may still have options, such as an independent foundation grant for epilepsy when funds are open.*

QuickRx reviews your situation and tells you which options you may qualify for. Call (917) 830-2525.

Medicare patients cannot use manufacturer copay programs. Other help may still be available, such as independent foundation grants, Extra Help (the Low-Income Subsidy) for patients who qualify, and state pharmaceutical assistance programs in some states.*

Vigabatrin is a seizure medicine with two approved uses: infantile spasms in babies 1 month to 2 years old, and refractory complex partial seizures in adults and children 2 years and older, added to other seizure medicines when several other treatments have not worked.

It works by raising GABA, a natural brain chemical that calms nerve activity. Because of the risk of vision loss, it is used only when the expected benefit outweighs that risk.

Vigabatrin comes as tablets, powder packets that are mixed with water right before each dose, and a ready-to-use oral solution. It can be taken with or without food. For adults, the usual starting dose is 500 mg twice a day, increased weekly as needed, with a usual dose of 1.5 grams twice a day. Doses for children are based on weight.

The powder mix (50 mg per mL) and the ready-to-use solution (100 mg per mL) are different strengths. Always measure with the oral syringe or cup provided, never a kitchen spoon. Follow the exact dose your neurologist gives you.

Vigabatrin has a boxed warning, the FDA’s strongest warning, because it can cause permanent vision loss, including tunnel vision. Vision loss can start at any time, and patients often do not notice it until it is severe. No dose is known to be free of this risk.

Because of this risk, vigabatrin is only available through the Vigabatrin REMS program, a safety program that prescribers and pharmacies must be certified in.

Vision should be checked by an eye specialist before starting or no later than 4 weeks after starting, at least every 3 months during treatment, and about 3 to 6 months after stopping.

Vigabatrin is usually stopped if it does not clearly help within 3 months for complex partial seizures, or within 2 to 4 weeks for infantile spasms. Call your doctor if you or your child bump into things, trip more than usual, or seem surprised by people or objects that come from the side.

In adults, common side effects include headache (33%), tiredness (23% to 28%), dizziness (24%), sleepiness (22% to 24%), tremor (15%), blurred vision (13%) and weight gain. In babies treated for infantile spasms, common side effects include sleepiness, irritability, ear infections, colds and fever.

Tell your doctor about any side effects that bother you or do not go away.

Sleepiness and slowed thinking: do not drive or use machinery until you know how vigabatrin affects you.

Mood changes and suicidal thoughts: like other seizure medicines, vigabatrin may raise this risk. Call your doctor right away about new or worse depression or changes in behavior.

Nerve problems, swelling, anemia and weight gain have also been reported.

Do not stop suddenly: stopping vigabatrin all at once can bring on more seizures. Your doctor will lower the dose slowly.

Yes. Vigabatrin can lower phenytoin levels and raise clonazepam levels. Alcohol, opioids and other medicines that cause sleepiness can add to its sedating effects.

Tell every doctor and pharmacist about every medicine, supplement and herbal product you take. QuickRx pharmacists can review your list; call (917) 830-2525.

Yes. Vigabatrin is cleared by the kidneys, so lower doses are used when kidney function is reduced. Older adults with kidney problems are also more likely to have strong sleepiness and confusion. No dose change is listed for liver problems.

Vigabatrin crosses the placenta, and birth defects have been reported, but there is not enough data to know the exact risk. Do not stop your seizure medicine on your own if you become pregnant; talk with your neurologist right away. Breastfeeding is not recommended by the manufacturer.

Store tablets and powder packets at room temperature, 20°C to 25°C (68°F to 77°F). Mixed powder should be used right away. Once opened, the ready-to-use oral solution can be kept between 2°C and 30°C (36°F to 86°F) and thrown away 90 days after first opening.
