At this time, no generic versions of Tirosint (levothyroxine) are available. The earliest predictable date that a generic version could be manufactured is after the first patent expires, which is in 2021. However, lawsuits or other patents for specific uses of the drug may delay the manufacturing of a generic product. Although there are generic levothyroxine products, none of them are equivalent to Tirosint.
Can I Buy Generic Tirosint?Tirosint® (levothyroxine sodium) is a prescription medication used to treat an underactive thyroid (hypothyroidism), as well as a few other thyroid problems (such as goiters, nodules, or thyroid cancer). It is the only form of levothyroxine that comes in a soft-gelatin capsule.
Tirosint is manufactured by IBSA Institut Biochimique SA for Akrimax Pharmaceuticals, LLC. There are no generic versions of Tirosint available at this time, as the medication is protected by a patent that prevents any generics from being manufactured.
When Will a Generic Version Be Available?The first patent for Tirosint currently expires in March 2021. This is the earliest predictable date that a generic version could become available.
However, there are other circumstances that could come up to extend or shorten this exclusivity period. This could include such things as lawsuits or other patents for specific Tirosint uses. Once the drug goes off-patent, there may be several companies that manufacture a generic Tirosint drug.
Is Levothyroxine a Generic Tirosint?None of the generic levothyroxine products are technically equivalent to Tirosint, as all the other products come in tablet form (and Tirosint is a soft-gelatin capsule). If you are interested in a generic form of levothyroxine, you will need to talk with your healthcare provider about getting a new prescription for one of the tablet formulations.
It is important to remember that levothyroxine (including Tirosint) is a "narrow therapeutic index" medication, which means that even tiny changes in the dose can result in large changes in the body. As a result, most healthcare providers recommend that you stick with one brand of levothyroxine if possible. If you do need to change brands, it is a good idea for your healthcare provider to do blood tests often to make sure that your dose does not need to be adjusted.
