Generic maker Teva Pharmaceuticals can start selling its version then, but isn’t disclosing the price. Many more generics go on sale next summer, which will steadily slash the price of generics, possibly by 90 percent. When generic Viagra comes out, they will be very happy,” said Dr. Nachum Katlowitz, a urologist at New York’s Staten Island University Hospital. Launched in 1998, Viagra was the first pill for impotence.
- Sildenafil white was first approved by the FDA in 1998.
- It is marketed under various brand and generic names worldwide.
- The drug belongs to a class called phosphodiesterase inhibitors.
- It is effective for many men with both physical and psychological ED.
- Sildenafil white may also help treat pulmonary arterial hypertension.
- Some users report experiencing visual disturbances after taking it.
- The medication’s effects last approximately 4 to 6 hours.
- It is advisable to avoid alcohol when taking sildenafil white.
- Consumers should check for potential drug allergies before use.

It transformed a private frustration for many aging men into a publicly discussed medical condition with an easy treatment, far more appealing than options like penile injections and implants. Pfizer’s early TV ads for the little blue pill even coined the term erectile dysfunction, ED for short. Eli Lilly’s Cialis came out in 2003 and now dominates the U.S. market with on-demand pills and daily, low-dose ones. Pfizer says its market research shows 20 percent of customers are loyal to Viagra. So rather than give up sales to generic makers as brand-name drugmakers once routinely did, the company is selling its own generic and also fighting to keep men on its blue pills. “We believe that the story for Viagra isn’t done. It’s just going to be a new chapter,” said Jim Sage, president of U.S. brands for Pfizer Essential Health, which sells its older medicines. In January, the drugmaker will offer two new discount programs and increase its copayment card discounts. Uninsured men can get brand-name Viagra half off through an innovative online home delivery program, Pfizer Direct. Many insured patients will be able to get a month’s prescription — typically six to 10 pills, depending on plan limits — for as little as a $20 copayment. “This is the most comprehensive pricing and marketing response I’ve seen to a generic,” said Erik Gordon, a pharmaceuticals analyst at the University of Michigan’s business school. Gordon thinks Pfizer’s reduced prices will retain some patients and attract others who buy pills, often counterfeits, from the internet.

"Supreme Court ruling could lead to cheaper versions of Viagra". Dr. Matthias Hofer, a urologist at Northwestern Memorial Hospital in Chicago, said some of his insured patients who take Viagra wouldn’t want a generic. “They will be ecstatic if they can save money and get the brand product from Pfizer,” he said. Last year, more than 12 million prescriptions for Viagra and Cialis were filled in the U.S., generating a combined $3 billion in sales, according to health data and clinical research company IQVIA.

However, prescriptions have dropped more than 20 percent since 2012, as repeated price hikes put the pills out of reach for many men lacking good insurance. According to health information analytics firm Elsevier, over just the past decade, retail prices jumped from about $10 to $62 per pill for Viagra and from $11 to $61 for Cialis. Pharmacies and other middlemen add a few dollars more per pill. Generic Viagra, called sildenafil, will become even more affordable starting June 11, when more versions go on sale. “Many patients already know it’s going generic and they want it,” said Aracely Pena, a medical assistant at San Diego Sexual Medicine. Cialis and Levitra, another pill launched in 2003, get their own generic competition next fall.
