The above information is for discussion purposes only and is not meant as specific medical advice for any individual. Read through all the good posts on seasickness, and try different treatments on land before any trip to see how they affect you. No one can tell you in advance which seasickness preventative will work best for you. Yes, scopolamine can make one sleepy, but if it doesn't make you sleepy it could be a good choice for you.

Which medications make lynnemari sleepy (or not) might also be irrelevant to you. The fact that Dramamine's meclizine fromulation is called 'Less Drowsy' is irrelevant to you if it actually makes you more drowsy. Which is more effective? Different medicines affect different people differently. For instance, like Dr Stein said, Dramamine Original Formula is dimenhydrinate, but Dramamine Less Drowsy Formula is meclizine! When you buy OTC meds, you should read the label and pay close attention to the active ingredients so you know exactly what you're taking. It's important to know which one you're talking about. Did you know that there is no OTC med in the US simply called Dramamine? There's Dramamine Original Formula, Dramamine Chewable Formula, Children's Dramamine Liquid, and Dramamine Less Drowsy Formula (at least, if not more). Doc Vikingo has written many good articles on the various methods to prevent seasickness so you might want to narrow your seach by including his board name in the search parameters. Do searches for meclizine, Dramamine, scopolamine, seasickness, etc. There's a whole lot of information on the board about seasickness treatments. Consult your physician for a motion sickness medication that is less likely to cause sedation/cognitive effects. Newer antihistamines produce less drowsiness in general but may interact with other types of medications. If you have no plans to dive on the otherhand, these medications are useful This could compromise a diver at depth and therefore should not be considered for an active diver. Which basically says that the drug dimenhydrinate (Dramamine) can cause serious cognitive problems. Coupled with the sedative action of nitrogen, antihistamines will have an additive effect. While they may well reduce or stop motion sickness, the medication many not really be appropriate for a diver. Many of the older antihistamines produce drowsiness. That is why Meclizine and Dramamine (diphenhydrinate) are used for their effects other than as an antihistamine. Certain antihistamines may actually have a very strong anti-nausea/anti-motion sickness action and therefore the drug is used for it's side effect. It turns out however, that one of the common side effects of antihistamines (in general) is to cause drowsiness, reduce or prevent nausea and motion sickness. Some side effects can sometimes severely limit the dose or usefulness of a particular drug. Thus, the chemical/physical reaction to the histamine is blocked or reduced.ДЄlmost all drugs have certain desired effects and certain 'side effects.' When blocked, these sites are no longer available to bind to histamine. You get the runny nose, itching eyes, coughing sneezing etc.ДЄntihistamines 'block' the chemical receptor sites within different tissues (found on the surface of cells). This class of drugs 'target' histamine receptors which, when stimulated by histamine released from local tissues in response to exposure to substances that initiate an allergic reaction. They are both classified as antihisamines.

You might want to think of Meclizine and Dramamine as 'cousins'.
