Viagra, a blue pill initially intended for cardiovascular issues, was accidentally found to treat erectile dysfunction. Its active component, sildenafil, was discovered to cause erections during trials. Approved by the FDA in 1998, it works by increasing cGMP levels, relaxing tissues, and promoting blood flow. Since its patent expiration in 2019, generic versions have emerged. Despite its original purpose, Viagra is now globally recognized for treating erectile dysfunction and is used recreationally.

Generic Viagra is accessible in the USA, with the original patent expiring in 2020. This allowed Teva Pharmaceuticals and other manufacturers to produce it. Pfizer also offers a less expensive, non-blue version. Generic Viagra has been available in Canada since 2012 and Europe since 2013. In the US and most countries, a prescription is required. Some online pharmacies offer virtual health assessments. It's crucial to choose licensed companies with U.S. addresses and be cautious of counterfeit Viagra sellers.

Since 2020, generic Viagra has been accessible in the United States, thanks to an agreement between Pfizer and Teva Pharmaceuticals. Other manufacturers also entered the market in 2020. Pfizer offers a white, half-priced version of the original blue pill. The drug is available in 25, 50, or 100 mg dosages. Online consultations and home delivery options are available for discreet purchasing.

Viagra, the first oral solution for erectile dysfunction, was approved by the FDA on March 27, 1998. Pfizer patented its active ingredient, sildenafil citrate, in 1996. Following approval, over 40,000 prescriptions were filled. By 2008, it generated $2 billion in annual sales. However, sales have dropped over 20% since 2012 due to price increases and generic competition.

Viagra, a well-known erectile dysfunction drug, was accidentally discovered by Pfizer researchers. Initially developed for hypertension and angina pectoris, it was found to be more effective in inducing erections during trials. The drug, which relaxes blood vessels to improve blood flow, was found to have the same effect on penile arteries. Approved by the US FDA in 1998, Viagra has since become a widely recognized prescription drug.
