Generic Tikosyn for Arrhythmia Now In Pharmacies

by The GoodRx Pharmacist on July 21, 2016 at 5:25 pm

Generic Tikosyn (dofetilide) has been approved by the FDA for some types of abnormal heartbeat: atrial fibrillation and atrial flutter—and is in pharmacies now.

Atrial fibrillation and atrial flutter are two common types of abnormal heartbeat that are often treated with the same medications, as many people experience both together. Atrial fibrillation is an irregular, often rapid heart rate that commonly causes poor blood flow. Atrial flutter is similar to atrial fibrillation but it causes the heart to beat in a fast, regular rhythm.

How is dofetilide be available?

Like brand name Tikosyn, dofetilide is available as a capsule in 125 mcg, 250 mcg, and 500 mcg strengths.

What are the side effects of dofetilide?

The most common side effects associated with dofetilide capsules include headache, chest pain, and dizziness.

What if I want to keep taking brand name Tikosyn?

If you would like to continue on brand Tikosyn, make sure your doctor handwrites BRAND MEDICALLY NECESSARY on your next prescription. This means the pharmacy is not permitted to substitute and give you the generic product.

Otherwise, you can still request that your pharmacist fills the brand medication for you—just make sure to ask before your prescription is filled.

Keep in mind that because the generic is now available your insurance company may not be willing to cover the cost of the brand medication. You may want to call your prescription insurance company to find out the potential cost (or if it’s covered at all) before wasting a trip to the pharmacy.

Are there any other ways to save if I keep taking the brand?

The manufacturer of Tikosyn has a Patient Savings Card for those who are eligible.

Eligible patients will get their Tikosyn for as little as $4 a month. The offer is not available for patients eligible for Medicare, Medicaid, or any other federal or state healthcare programs.
