10 records since 2012. A record is one product or lot, not one recall event. Combination products that contain sildenafil are included.

What these numbers mean

NADAC is what retail pharmacies pay on average to buy the drug, published by CMS. It does not include rebates and is not what you pay at the counter. ANDA counts include all strengths and forms and applications whose products are now discontinued.
