Hi There, I'm Currently Recovering From A Bad Dose Of

Hi there,

I'm currently recovering from a bad dose of the 'flu. I've been taking cortisone and antibiotics. For the first time, I've developed hypertension and I'm experiencing headaches. I'm also taking Lexapro, Crestor and mirtazapine. Could my symptoms be due to an interaction of the drugs?
Please note that I had a recurrence of prostate cancer three years ago, but it's currently in remission.

Thank you.
