Frequently Asked Questions

You and your patients may have questions about accessing VYNDAMAX. Below are some frequently asked questions to help you learn about VyndaLink support.

How long will it take for my patients to receive the medication after I’ve prescribed it?

On average, it takes several weeks for a patient to receive VYNDAMAX after you have written the prescription. Depending on the patient’s case and individual circumstances, however, it may take longer, for example, in situations where the plan denies coverage and an appeal is filed. If you have questions about the status of your patient’s case throughout this process, please contact VyndaLink or a Pfizer Field Access Specialist.

How can my patients sign their portion of the VyndaLink Enrollment Form?

Please see the Patient e-Sign Guide on the Resources page. Patients can sign electronically via the e-Sign functionality on or, for patients enrolled via the Provider Portal, they can either sign electronically while in the office or afterwards via the email they will receive from the Portal.


Alternatively, patients may continue to sign the physical Enrollment Form if your office prefers to download the form and fax completed Enrollment Forms to 1-888-878-8474.

What steps do I take for a prior authorization (PA)?

After you have submitted a PA (including letter of medical necessity) to your patient’s insurer and received a determination, please notify VyndaLink so that we can continue to process your patient’s case. You can call VyndaLink with the insurer’s decision, fax the PA determination, or submit the documentation via the VyndaLink Provider Portal.

When a coverage determination is made, what do I need to do?

After you have submitted a PA to your patient’s insurer and you’ve received a determination, please send the documented decision to VyndaLink via fax or the VyndaLink Provider Portal, if you are registered. If you completed a verbal PA, please notify VyndaLink so we can continue to process your patient’s case.

What happens if my patient’s PA is denied?

If a PA is denied, please notify VyndaLink and share the denial. If you choose to file an appeal, VyndaLink can assist by explaining what information is required by the patient’s plan, but it is your responsibility to fill out and submit any appeal on the patient’s behalf.

Is financial assistance available for my patients?

VyndaLink can help identify financial support options for eligible patients. Patient out-of-pocket costs will vary depending on insurance coverage. Please see the Affordability page for more information on financial assistance.

What is a Pfizer Field Access Specialist (FAS)?
