Allergy sensor patches

hello!I'm writing here because for some time now every time I put on a patch to keep the sensor from coming off I end up with rashes, irritation or wounds on my arm and I have to take them off.I have tried everything: adhesive sprays and nothing;I have tried (following the dermatologist's advice) to hydrate my arm more before having to change the sensor and I ended up the same;Patches for hypoallergenic/more sensitive skin are misleading and I end up with the same problem;I have used films that the dermatologist or my nurse at the health center left me... and I always get a wound after a few days.

Now the hot season is back, when those patches are most commonly used, and I think I can't stand another summer with injuries on my arms or having to change the freestyle every two or three days because it's exasperating (last year I even ended up wearing straps for several weeks because it was more comfortable for me).

I'm trying to get them to switch to the dexcom plus because last year a friend gave me several to try and the patch that came with the sensor irritated me, but not much.I don't have an appointment until July and I don't want to waste these months with my arms full of wounds.

Does anyone have the same thing happen and know of any new tricks I can try?

Do you clean the area where you are going to put the sensor well with alcohol?I clean my skin with alcohol, even if I have just showered, and I hope that the area where I am going to apply the sensor dries well.I use the Libre 3 which, being very small, makes it difficult for you to attach it.It also doesn't irritate my skin like it did with the Libre 2.

It's not just the patches that irritated me, it's that even the free one was a real torture from minute one... Patches happen to me especially in the summer, but not only... I tried different supposedly protective sprays, with three or four layers instead of one or two... and nothing, there was no way, in the end I ended up wearing a bracelet to prevent it from falling off, because on top of that it would half peel off after a few days...

In the end, since I pay for it, I have switched to the dexcom one, and for now, neither the sensor nor the patch that comes with the sensor itself irritates me, let's see later with the heat... it is also smaller and more difficult to hook it on things.And you can put it in more places, not just on your arm.Of course, you almost need a spatula to remove it (I'm seriously considering buying one of those sprays to remove it, because I get small bruises when pulling...).

With the free 3 the same thing happened to me as with the 2 in terms of itching and irritation... and yes, I clean the area well with alcohol even if I have just showered, I hope it dries... it doesn't matter, my skin is awful with tapes and the like...

Hi @isagt,

I don't know what products you used to fix the sensor.Many people talk about skin tac wipes to set the meter and create a protective barrier on the skin, although I have not used them.

In any case, while you wait to change to Dexcom I would try using other parts of the body to give your arms more rest.In addition to testing your arms, thighs, abdomen, or lower back.

This will not solve the skin irritation problems, but at least you are not continuously exposing the same area, and you allow more time for it to recover.When you remove the sensor, use a spray with vitamin E, or moisturizing cream, to soothe the area in the following days.Try not to repeat the same area within 30 days, and perhaps the irritation will not be as strong since the recovery time will have been longer.

Yo uso brazaletes elásticos sobre el sensor y también, aúnque sobre todo en los catéteres de la bomba, spray protéctor Cavilón. Luego , al retirarlos, Cicalfate plus de Avene

¡hola! escribo por aquí porque desde hace un tiempo cada vez que me pongo un parche para que no se despegue el sensor acabo con sarpullidos, irritación o heridas en el brazo y me los tengo que quitar. he probado de todo: sprays adhesivos y nada; he probado (siguiendo el consejo de la dermatóloga) a hidratar más el brazo antes de tener que cambiar el sensor y acabo igual; los parches para pieles hipoalergénicas/ más sensibles son engaño y acabo con el mismo problema; he utilizado films que me han dejado la dermatóloga o mi enfermera del centro de salud... y siempre me sale una herida a los pocos días.

ahora vuelve la época de calor, cuando más se suelen usar esos parches, y creo que no aguanto otro verano con heridas en los brazos o teniendo que cambiar el freestyle cada dos o tres días porque es desesperante (el año pasado incluso acabé varias semanas con tiras porque me resultaba más cómodo).

estoy intentando que me cambien al dexcom plus porque el año pasado una amiga me dio varios para probar y el parche que venía con el sensor me irritaba, pero no mucho. no tengo cita hasta julio y tampoco quiero tirarme estos meses con los brazos llenos de heridas.

¿a alguien le ocurre lo mismo y conoce algún truco nuevo que pueda intentar?


A mí ya no es que me irritasen solo los parches, es que hasta el free, era una verdadera tortura desde el minuto uno... Lo de los parches me pasa sobre todo en verano, pero no solo... Intenté con diferentes sprays supuestamente protectores, con tres o cuatro capas en vez de una o dos... y nada, no había forma, al final acabé usando un brazalete para evitar que se me cayese, porque encima se me medio despegaba a los pocos días...

Al final, como me los pago yo, pues he pasado al dexcom one, y de momento, no me irrita ni el sensor ni el parche que trae el propio sensor, a ver más adelante con el calor... también es más pequeño y más difícil engancharlo con cosas. Y se puede poner en más sitios, no solo en el brazo. Eso sí, se necesita casi una espátula para quitarlo (me estoy planteando seriamente comprar un espray de esos para quitarlo, porque me hago pequeños hematomas al tirar...).

me olvidé de la contraseña de este foro y se me olvidó contestar. Puf, me pasaba lo mismo. Conseguí que me lo cambiaran, pero en los últimos meses que usé el libre también el pegamento del sensor me creaba irritación y el filamento este que medía la glucosa me dejaba una herida. el dexcom one+ no noto que me haga sarpullidos o rojetes, pero el parche con el que viene me empieza a picar a los 5 días y me lo acabo quitando... pero bueno... algo es algo jajaja
