Because product safety and quality are important

Please see full Prescribing Information for Kogenate FS

Our manufacturing process exemplifies Bayer's dedication to the quality and safety of your treatment – from fermentation to purification to filling and freeze drying to packaging. For example:

We produce Kogenate® FS, Antihemophilic Factor (Recombinant), using continuous perfusion technology to obtain the factor. This continuous harvesting allows FVIII proteins to spend less time in the fermenter, leading to a consistent and high-quality FVIII molecule.

Multistep purification process
We use a multistep purification process designed to purify rFVIII and remove contaminating substances.

Filling and freeze-drying in a high sterility environment
In the fill room, we fill our vials with the proper amount of Kogenate FS and then freeze-dry it to create a powder. The fill room meets the high sterility standards set by the pharmaceutical industry.

Twice-inspected vials in exclusive tamper-evident cartons
We personally inspect the glass vials that contain Kogenate FS twice to ensure quality. Then, we place them into cartons with exclusive anti-counterfeiting and tamper-evident features for protection from the factory all the way to your use.

Speed, ease and convenience

One compact box is small enough to fit in your backpack, briefcase or purse with ease, so you can infuse on the go.
