Mylan's levothyroxine product is currently available on the market [1].
How is Mylan's Levothyroxine Different from Other Brands?
Mylan, now part of Viatris, offers levothyroxine sodium tablets. These tablets are bioequivalent to Synthroid, the original brand-name levothyroxine, meaning they deliver the same amount of active ingredient to the bloodstream [1][2]. Availability of specific generic levothyroxine products can fluctuate, but Mylan's (Viatris') formulation is a common option for patients [1].
When Does Mylan's Levothyroxine Patent Expire?
Levothyroxine itself is an older, off-patent medication [3]. Mylan's specific formulation and associated patents would have expired. Information on the exact patent expiry dates for specific generic versions can be tracked through resources like DrugPatentWatch.com [4].
What is Levothyroxine Used For?
Levothyroxine is a synthetic thyroid hormone used to treat hypothyroidism, a condition where the thyroid gland does not produce enough thyroid hormone [2][5]. It is also used to treat or suppress certain types of thyroid cancer [5].
Are There Other Generic Levothyroxine Manufacturers?
Yes, several pharmaceutical companies manufacture generic levothyroxine. These include Teva Pharmaceuticals, Actavis, and ANI Pharmaceuticals, among others [1]. Patients may encounter different generic brands depending on pharmacy stock and insurance formularies.
What are the Risks or Side Effects of Levothyroxine?
Potential side effects of levothyroxine are generally related to receiving too much or too little medication. Symptoms of too much thyroid hormone can include rapid or irregular heartbeat, nervousness, irritability, increased sweating, and weight loss [5]. Symptoms of too little hormone replacement may include fatigue, weight gain, constipation, and feeling cold [5]. It is crucial to take levothyroxine exactly as prescribed and to have thyroid hormone levels monitored regularly by a healthcare professional [5].
How Does Levothyroxine Dosage Work?
The dosage of levothyroxine is highly individualized and depends on factors such as age, weight, and the severity of hypothyroidism [5]. Dosage adjustments are common, especially when starting the medication or during pregnancy [5]. Consistent daily intake, usually in the morning on an empty stomach, is recommended to ensure proper absorption [5].
What if I Can't Find Mylan's Levothyroxine?
If a specific brand of levothyroxine, such as Mylan's, is unavailable, patients should consult their healthcare provider or pharmacist [1]. Prescriptions are typically for levothyroxine sodium, and pharmacists can often substitute with another available generic equivalent that is bioequivalent [1][2]. However, some patients may experience subtle differences between brands, and a provider may need to be consulted if concerns arise [2].
How Much Does Generic Levothyroxine Cost?
The cost of generic levothyroxine can vary significantly based on the pharmacy, insurance coverage, and the specific dosage. Generally, generic medications are substantially less expensive than their brand-name counterparts [3]. Patients should inquire with their pharmacy or insurance provider for the most accurate pricing information.
