For what it's worth, you should get competent advice from someone who knows before flying after use of any meds. But the truth of the matter is, FAR 61.53 makes you your own flight surgeon, by placing the responsibility for medically grounding and ungrounding, squarely on you. Again, I recommend you make this kind of decision only after seeking competent advice (which, in some cases is not your local AME: many of them do so few medicals and have such little aviation medicine expertise that they just don't know, no matter how well meaning they are). Amen. I wasn't going to take the time to add anything to this thread, but can't resist a summary. Pilots may be: 1: Unimpaired 1B: Unaware of impairment (feels the same as unimpaired) 1C: "Potentially" impaired (by meds, fatigue, etc.) 2: Impaired and aware of it. 2B: Able to compensate or escape to safety 2C: Unable to compensate or escape Advice-givers should generally refrain from recommending anything that could be associated with potential impairment (see elsewhere in this thread for instances of such). Pilots are responsible for self-assessment, but as this is difficult (impossible to do objectively), should seek and welcome observations and counsel of others in the decision not to fly. Example of "medical" impairment: Simply stay sober while watching other people consume ("medical") alcohol at a social gathering. If you're watching carefully, just ONE drink changes the verbal and motor performance of everyone except a daily-drinker. They s-l-o-w d-o-w-n mentally, physically, verbally. Example of physical impairment relevant to this thread: motion sickness and the sopite syndrome (motion-induced drowsinesss): I get very sleepy before I get sick; vomiting on my shirt on final (which I've done) is not as distracting, in my experience, as experiencing micro-sleep while thermaling (which I've done). I realized this spring that this is getting worse for me; one April day at 3000 agl, I forced myself to make 2 decisions: one, to return, land, and stow the glider; two, to decide whether I should quit soaring. My decision is relevant to the suggestion by some that motion-sickness drugs are all right because they help, because the impairment of drug (undetected by the user) is less than the impairment of the motion sickness (unavoidable and distracting). My decision was to *acclimate*, not to take medications - the 'treatment' was to take soaring flights more often, briefly, to acclimate to motion sickness, and to drink a cup or two of coffee before lunch (caffeine has been shown to enhance performance slightly) on soaring days. As an AME, physician, and opinionater, I feel quite safe in recommending that one acclimitize. There are ways to do this other than flying; I know of an aerobatic pilot who stood on his head several times a day to maintain acclimation during non-flying periods; or play that involves spinning and jumping should also help. On the other hand, I do not feel quite safe in recommending that anyone fly when potentially or actually impaired. In saying this, I realize that some tasks are simple and hard to mess up, e.g., local soaring on a sunny calm day. And other tasks are exceedingly complex, e.g., single-pilot hand-flown IFR in IMC, at night, in rain or snow, to minimums, in a complex turbocharged airplane, or contest flying on the ridge with complex navigation and planning tasks. (We just lost a colleague in NZ like this, obviously one factor went undetected; what it was, we'll never know.) Thus "Impairment" is relative to the task at hand. Best wishes, Dan Johnson |

Indeed - if one is so affected. If one is not so affected, no problem. As a physician and aviation medical examiner I wish to demur as clearly as possible from any recommendation to use scopalamine for motion sickness while flying. You go right ahead, and welcome. I never have felt the need to use a patch while flying because, although I am plagued by sea-sickness, I have never had any significant problems in the air. If I did start to suffer air- sickness, however, I would cheerfully consider using Scopaderm TTS patches. They are available in the UK as an over-the-counter medicine, and the relevant warning simply says (and I quote) "This medication causes drowsiness which may continue the next day. If affected do not drive or operate machinery. Avoid alcoholic drink." Note that "if affected". As I wrote before, I have spent months of my life wearing these patches and have noticed no side effects at all, save a slightly dry mouth which is useful reassurance that the patch is active. I'm not a doctor (well, not your sort). I'm not making any recommendations. I am, however an experienced user of Scopaderm, and I have a healthy desire to preserve my own life. Best wishes, Ian |

Who is going to judge if you are affected? Judging ourselves is the hardest thing to do. That's a very good question. Can I stress that I would only consider wearing the patches while flying as a last resort. As for effects, there are two categories. First, drowsiness. I have worn them enough to be confident that FOR ME there is no problem with drowsiness. It's only a potential side effect - some people are strongly affected and some not at all. Second, other impairments. I have not seen anything in the literature - I read this up quite carefully, as a lay person, before using the patches whilst sailing single-handed - to back up the suggestion that Scopolamine generally or even commonly has similar effects to alcohol. If I did decide to try it then I would certainly fly with an instructor and ask for a really tricky check flight. Any problems and of course I wouldn't fly solo. Ian |

The same person that judges if you are fit to fly based on all factors: Had enough sleep? Backache? Headache? Leg(s)/Arm(s) ache? Emotionally fit? The list is endless. If you are in doubt about being able to judge if you are fit to fly, then don't fly. Regards, -Doug |

It is up to you and your judgment to decide to do something like what Ian has suggested: "If I did decide to try it then I would certainly fly with an instructor and ask for a really tricky check flight. Any problems and of course I wouldn't fly solo." Now, if this drug is so perverse that when taken it causes one to then cancel the flight evaluation, then we really do have a problem. ;-) Regards, -Doug |

The problem as I understand it with this drug is that what it impairs in those affected are the faculties we use to decide if we are impaired... That claim has been made, but I have seen no evidence here or elsewhere to support it. The four main side effects of Scopolamine - are dry mouth, drowsiness, dizziness and blurred vision. Of these only the dry mouth is common. The claim that a Scopaderm TTS patch has the same effect as a glass of wine does not seem to be borne out by the literature, though I am happy, as always, to take correction on that point. Ian |
