    Cutting the Scopolamine Patch in 1/2

    I'm pretty prone to seasickness so I use the patch on my boat dives.. Question~ is the patch as effective if it's cut in half for a single days use? It seems wasteful to use a 3 day patch for just 1 day of diving, so by cutting it in half I should be able to get another day of diving at a later date.... right? HOWEVER--- the website (http://www.transdermscop.com/information.htm ) says not to cut the patch in half, but it doesn't say why...
    So, it either (a) screws up the release of medication into your system when you cut it, or (b) the manufacturer says you have to use a whole patch each time so they'll make more $ because you have to refill your prescriptions more often.

    Anyone know?


    (getting a hold of my doc isn't an easy task, especially for a trivial question... otherwise I would've asked already)

    Hi MissyP,

    Cutting the patch could adversely affect the drug delivery system and adhesiveness of the patch.

    Not without seeing how the patch is made, cutting it in half might accelerate the dehydration of the medicine soaked center. The technology might be more complicated that simply adhesive laden with medicine.

    It is kinda like trying to split a slow release capsule .... All of a sudden, it is a rapid release capsule. If you ever pooped one of these capsules out, it is just a shell with a tiny hole on it.....

    Hi fisherdvm,

    In other words, it "could adversely affect the drug delivery system?"

    I used to cut the nicoderm patches in half while quitting smoking, and at 24 hours I could feel the need for nicotine again, then they started stating to throw the patch away if it was cut. They found out people were using the full dose patch in smaller doses (size) saving money. I believe the medication is in the adhesive and the outer is just a cover.

    Hi dlndavid,

    Cutting Nicoderm patches can release the contained nicotine oil in larger than intended amounts, possibly leading to overdose.

    Depending upon the amount absorbed and individual sensitivity, nicotine can cause nausea, vomiting, diarrhea, abdominal pain, headache, dizziness, disturbed hearing and vision, confusion, irregular heartbeat, chest pain, seizures and death.

    Even in milder form, overdose could predispose to diver panic.

    It's not worth the savings.

    Regards,

    I keep thinking that members will learn that when DocV posts and answer, they need to read - not type.

    I'm not sure what effect this would have on the delivery system, but how about taking the patch off when you're done with it, placing it back on the plastic backing and in it's packaging? Maybe even put it in a ziplock. I'm not sure if once the system is activated by placing it on your skin whether it will just keep releasing for 72 hours, but this would definitely be better than cutting the patch. Check with your pharmacist to see how that would work before trying it. This is not something I've tried. It's just a thought. Post what you find out. I'm interested in knowing the effect.

    RE: Re-using nicotine replacement patches.+

    I can save one the time of asking their pharmacist. No competent, reputable pharmacist would endorse such an action.

    Moreover, what kind of savings are we really looking at from all this risky business?

    Online brand name patches can be purchased for a little over $3 each in packs of 14; generic patches cost a little over $2 each in packs of 7.

    Considering what post #6 has to say about nicotine overdose, is it worth it?

    Regards,

    As DocV said - don't cut them.

    Patches are one of the most technically advanced dosage delivery systems the drug industry puts out. Two general types are available, reservoir patches where a dose of the drug in contained in a pocket and release is controlled by the polymer film next to the skin, and matrix patches where the drug is contained in a polymer matrix that will release it over time. Given that the SCOP patch has been around for many years I would think that it is a reservoir design. Cutting it will cause dose dumping of the active - not a good thing.
