hi you need to get back to your doctor asap this all caused by her hormones kicking in as she is on her period. hope this helps you. good luck
can taking minipress during a heavy period cause increased dizziness and nausea? . my 16 yr. old daughter started taking 1mg of minipress about 10 days ago for nightmares due to ptsd. she felt a little dizzy in the beginning but was beginning to adjust to the medication. she started her period and all of a sudden the dizziness and nausea has gotten significantly worse.
