While "Generic Vesicare" is a common search term, it refers to the generic versions of the brand-name drug Vesicare (solifenacin succinate). Vesicare is prescribed to treat overactive bladder (OAB) with symptoms of urinary urgency, frequency, and incontinence [1].
When will generic Vesicare be available?
The exclusivity of Vesicare has been a subject of patent litigation. In 2021, a U.S. court ruled that certain patents protecting Vesicare were invalid. This ruling paved the way for generic manufacturers to launch their versions of solifenacin succinate [2]. Generic versions of solifenacin succinate are now available in the market [3].
What are the active ingredients in Vesicare and its generics?
The active ingredient in Vesicare and its generic equivalents is solifenacin succinate [1]. Solifenacin succinate works by relaxing the bladder muscle, which helps to reduce the urge to urinate and the frequency of urination [4].
How do generic solifenacin succinate drugs compare to brand-name Vesicare?
Generic drugs are required to be therapeutically equivalent to their brand-name counterparts. This means they contain the same active ingredient, dosage form, strength, and route of administration. The U.S. Food and Drug Administration (FDA) mandates that generic drugs have the same safety and efficacy as the brand-name drug [5]. Therefore, generic solifenacin succinate should work in the same way as Vesicare for treating overactive bladder.
Why might a doctor prescribe Vesicare instead of a generic?
While generic options are available, a doctor might sometimes prescribe the brand-name drug. This could be due to a patient's specific response to the medication, the availability of certain formulations, or in some cases, insurance formulary preferences. However, generally, when a generic is available and approved by the FDA, it is considered a safe and effective alternative [5].
What are the potential side effects of solifenacin succinate?
Like the brand-name drug, generic solifenacin succinate can cause side effects. Common side effects include dry mouth, constipation, blurred vision, and indigestion [1]. More serious, though less common, side effects can also occur, and patients should discuss any concerns with their healthcare provider [4].
How much do generic Vesicare (solifenacin succinate) cost?
The cost of generic medications is typically lower than their brand-name counterparts. The exact price of generic solifenacin succinate can vary depending on the pharmacy, insurance coverage, and dosage [6]. It is advisable to compare prices at different pharmacies or consult with a pharmacist for the most up-to-date pricing information.
Who manufactures generic solifenacin succinate?
Several pharmaceutical companies manufacture generic versions of solifenacin succinate. These include companies like Teva Pharmaceuticals, Aurobindo Pharma, and Mylan, among others [3].
