The medicated plasters are able to treat various disorders, from back pain to nausea, from rheumatism to cellulite. Some of the active ingredients contained in these devices act locally, releasing the substance where needed; others are absorbed transdermally and enter the bloodstream producing a general effect .
Compared to other pharmaceutical forms, the patches are easy to apply and the released substance acts for a prolonged and constant period.
The operation that precedes the application of transdermal devices involves the careful reading of the illustrative leaflet: some patches, in fact, must be dampened, while others cannot be cut, covered with a plaster or kept in the shower.
The medicated plasters must be placed on clean, dry, lint-free and non-irritated skin; their surface must therefore be firmly pressed and gently rubbed to promote better adhesion. During this phase it is important not to touch the part that contains the active ingredient.
In summer, place the patch in parts not exposed to the sun (especially if it is used for contraception or to control menopausal disorders). If possible, then, always apply the patches in different places, to prevent the skin from becoming irritated and becoming hypersensitive to the product; the risk is that the cutaneous capacity to absorb the active principle will be less.
