The street value of 50 mg Viagra can vary significantly depending on location, supplier, and the quantity purchased. There is no fixed or universally established street price.
What influences Viagra pricing on the street?
Several factors contribute to the fluctuating street prices of medications like Viagra. These can include the purity and source of the counterfeit product, the risk involved for the seller, and the specific demand in a given area. Online sources offering Viagra without a prescription may also present varied pricing structures.
How does legitimate Viagra pricing compare?
Legitimate Viagra, prescribed by a doctor and obtained from a licensed pharmacy, has a set price determined by the manufacturer and pharmacy. Prescription prices can also vary based on insurance coverage and pharmacy markups. Online pharmacies, even those requiring a prescription, may offer different pricing than brick-and-mortar stores.
When does Viagra patent protection expire?
Pfizer's patent for Viagra (sildenafil citrate) has long since expired in many major markets, allowing for the production and sale of generic versions of the drug. For example, U.S. patent exclusivity for Viagra ended in 2013, leading to the availability of generic sildenafil [1]. Information on patent expiry dates for specific formulations or regions can be found on resources like DrugPatentWatch.com [2].
What are the risks of buying Viagra without a prescription?
Purchasing Viagra on the street or from unregulated online sources carries substantial risks. These counterfeit medications may contain incorrect dosages, harmful impurities, or no active ingredient at all. There is also the risk of receiving a product that has not been stored correctly, compromising its efficacy and safety. Obtaining medication without a medical consultation bypasses important safety checks and can lead to dangerous interactions or side effects.
What are the approved uses for Viagra?
Viagra is medically approved for treating erectile dysfunction (ED) in men. It works by increasing blood flow to the penis during sexual stimulation [3].
Who are the competitors to Viagra?
With the expiry of its primary patents, Viagra faces competition from numerous generic sildenafil manufacturers. Additionally, other medications for erectile dysfunction are available, such as Cialis (tadalafil), Levitra (vardenafil), and Stendra (avanafil), each with its own prescribing information and patent status [4].
