How long to get prior authorization??

Hi all,

Girlfriend is waiting to start Briumvi. The pharmacy says they are waiting to get a prior authorization from my doctor. We met with the doctor on January 2nd. This feels like it's taking too long. Is this normal?

We are not in love with this neurologist because they are poor communicators, but we are nervous to switch to a new neurologist before she does her first Briumvi doses, because we don't want to push off the start date even more. We don't even know how we would go about switching neurologists.

We are getting nervous because first MS symptoms appeared in September 2023, but diagnosis was not confirmed until December 2024, so we are keen to get things moving ASAP.

Any advice on how long it should take to get the treatment, as well as any advice on switching neurologists would be very helpful.
