Mycophenolate - Trigger?

G'day,

Over the past 12 months my migraines have increased 4-fold.

I've just seen a specialist, and his primary "answer" was - Even though I've had consistent migraine frequency for 30 years (6-10 per year), they can suddenly change frequency for no discernible reason.

(He did check that I had no new symptoms, no other major changes in life / lifestyle, and ultimately said it is either just "because it happens", or is possibly due to some pretty major family stresses I'm experiencing.)

About the same time frame as my migraines have increased, I have also started taking Mycophenolate. It's about the only other factor I can think of that fits the time frame of my increase in frequency.

Has anyone ever linked this to migraine?

Thanks.
