It is important to use the correct amount of topical steroid for your eczema, as instructed by your healthcare professional. Topical steroids should be applied with clean hands so that the skin just glistens. It can sometimes be difficult to judge how much steroid to use and there are guidelines on the amount required to cover body areas that are affected by eczema. These are based on the Finger Tip Unit (FTU), and explained in detail in our fact sheet which you can download as a pdf from the related documents to the right of this page.
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.
