Bupropion, also known as Wellbutrin (as an anti-depressant) and Zyban (as a smoke cessation aide) has a
black box warning for suicidal tendencies and suicide completion.
Anti-microbial drugs (antibiotics) that contain fluoroquinolones, such as Avelox, Cipro and Levaquin, have warnings because they can increase the risk of tendinitis and tendon rupture, especially in patients over 60 years old.
