Type blood symptoms and conditions

Anyone aware that the book "Eat Right for Your Type" (Peter D'Adamo)mentions that certain blood types should avoid fluoroquinolone antibiotics? My dad had type B or AB, not sure, and suffered severe side effects to Levaquin. I am sure that these are the types that must avoid these drugs.

I am asking a question on behalf of my brother. He had a stent inserted about 5 years ago due to blockage in one artery. The doctor put him on 20mg Lipitor and Plavix. Ever since then he has been getting Afib. Twice he has had to go to the hospital to get his heart back in rythm and other times he's able to get it back on his own. He has cut back to 10mg Lipitor and takes 100 mg COQ10. Has anyone else had Afib with Lipitor? He seems to think it's the stent causing it and I'm convinced it's the Lipitor. By the way, his cholesterol was not high, only his triglycerides. Thanks for any input.
