Norvasc, a medication used to treat high blood pressure and angina, is available in generic form, meaning its patent protection has expired. The active ingredient in Norvasc is amlodipine besylate [1].
When did generic Norvasc become available?
Generic versions of Norvasc began appearing on the market following the expiration of its primary patents. The initial patent for amlodipine expired in 2003 [2]. This allowed multiple pharmaceutical companies to manufacture and sell generic amlodipine, increasing accessibility and affordability [1].
What is the difference between Norvasc and generic amlodipine?
The primary difference between brand-name Norvasc and its generic equivalent, amlodipine besylate, is the inactive ingredients. Both contain the same active ingredient, amlodipine, in the same dosage. Regulatory bodies like the U.S. Food and Drug Administration (FDA) require generic drugs to be bioequivalent to their brand-name counterparts, meaning they must work in the body in the same way [3]. Minor variations in inactive ingredients do not affect the drug's safety or efficacy [1][3].
Who makes generic amlodipine?
Numerous pharmaceutical companies produce generic amlodipine besylate. These include manufacturers like Teva Pharmaceuticals, Mylan (now Viatris), Sandoz, and Aurobindo Pharma, among others [4]. Availability may vary by region and pharmacy [1].
How much does generic Norvasc cost?
The cost of generic amlodipine besylate is significantly lower than that of branded Norvasc. Prices can vary widely depending on the pharmacy, insurance coverage, and dosage. However, generic medications are generally 80-85% cheaper than their brand-name counterparts [5]. Patients can often find discounted prices through various pharmacies or by using prescription discount cards [1].
What are the uses and side effects of amlodipine?
Amlodipine is prescribed to treat hypertension (high blood pressure) and coronary artery disease, specifically angina pectoris (chest pain) [1]. Common side effects include swelling of the ankles or feet, drowsiness, dizziness, flushing, and headaches. More serious, though less common, side effects can occur and medical attention should be sought if they arise [6].
What if my insurance doesn't cover Norvasc?
If insurance does not cover brand-name Norvasc, a healthcare provider can typically prescribe the generic amlodipine besylate, which is almost always covered by insurance due to its lower cost. For those without insurance or facing high co-pays, generic amlodipine is available at significantly reduced prices from various pharmacies and through prescription discount programs [1].
