That sounds odd I know but consider the following about the quit smoking drug Chantrix:

The FDA has been analyzing reported adverse events which includes suicidal thoughts and suicidal behavior in Chantix users since late last year.

Whoops! I guess we don’t want that in our pilots do we?

“In November, we had put on the [Chantix] label a precaution about use when operating heavy machinery,” Janet Woodcock, MD, director of the FDA’s Center for Drug Evaluation and Research, told WebMD.

“Every drug is not right for every person,” says Woodcock. “If they’re in a specialized occupation where sedation or other problems might pose an extra risk, then if they need to go on a drug like this, they need to take a brief pause from that occupation or not do it while they’re, say, flying an airplane.”

Not a pilot, trucker, or bus driver? If you drive at all, you should still take note of drug labels. “Many, many medications can impair your driving ability,” says Woodcock. “People should be very careful when they’re taking any medication that has these labeled precautions.”
