Thank you all for trying to help. The situation was that a refill at home was not accomplished in time due to Memorial Day. We chartered a boat out of Marigot, and after our trip we had a room at Divi Little Bay for a few days. It would have been all sorted out and we would have had her Rx delivered to Marina Fort St. Louis when we got back, but the pharmacy back home sent us someone else's Rx!!! We ended up getting a pharmacy in Phillipsburg to provide the medicine, where it was actually over the counter!
Oh well, our pharmacy back home made it all right afterwards, even paying us back for the FedEx delivery!
