Bayer welcomes you and your family to our WVNHF booth. Bayer has a rich history in supporting the bleeding disorders community in West Virginia. During this challenging and unprecedented time, we remain committed as ever to ensuring uninterrupted access to our medicines. If you need assistance. Call 1-888-842-2937. While you are here, I would welcome the opportunity to discuss the role of pharmacokinetics and individualizing your Hemophilia A treatment. Like a fingerprint, a PK profile is different for every person with Hemophilia A- there is nobody else quite like you! This profile can be used to make sure that the drug is given in the right amount and at the right frequency.
