Hi. I'm in Ireland, and the protocol here is that when your LS is under control to try once daily applications of over- the-counter1% hydrocortisone cream - this is a very low dose cream, about one hundred and fifty times weaker than the clob, so its very important never to miss a day. You can go to twice or three times daily on the least suspicion of a flare-up. I havn't used clob for two years now and so far so good. Here's a link to a good site comparing relative steroid potencies: http:///docs/
Swimmer's itch is caused by many different factors. Since the disease is really a disease of aquatic birds, the target should be to reduce the possibilities of the birds getting infected. In some small ponds and lakes, the snails that harbor the parasite can be killed by chemical molluscicides. The possible environmental effects of chemical molluscicides mean that this approach cannot be recommended in all situations. A newer approach has been to place a drug for treatment of the parasite into food bait. Other drugs are currently being tested. Indirectly, it is important that the vegetation in the pond or the lake be kept to a minimum so that the snails do not have the ideal environment to grow.
