.... more than one might think. A relative in the Army was threatened off the books with hell to pay if he didn't take Larium. He protested personally to his boss because of the psychological issues Larium can cause (I'm sorry I don't know military ranks) but found no sympathetic ears. So he decided to give in and make no formal complaint. After taking Larium regularly for a year or two, he was in the Middle East working on a vehicle and had a massive seizure. He also then discovered that the Larium had reacted with a particular genetic condition to make him permanently sterile. So now he can't have kids, although he wants them badly, and has had migraines and balance problems since. He is a very honorable person, and since he was a career guy, he never sued, even though his genetic condition was on file, and there was obvious medical malpractice. He was close to retirement when it happened, and he just wanted to get out as smoothly as possible.
