You need to make certain your doctor will assist with these orders.
Then call medical supplier.
Of Note:
Choosing supplies is like rolling dice cause you must try products first.
If you have a prolapsed stoma you need convex wafers.
Brava is the best line I have found.
Just do not short yourself.
Look through catalogs then create your list.
The supplier can be a pest to a doctor so create a list that truly covers all things you will need
Hydrocolloid tapes and protective sheets are a god send.
I have not had luck with stoma care nurses.
The Rx will need updating yearly with doctor chart notes.
Be sure and measure your stoma so you know the size of wafers and pouches.
Again accessory items like Hydrocolloid are needed in my opinion.
They are expensive but if you have a difficult appliance application you will need them.
Calamine lotion comes in handy.
Destin with Zinc is useful too...a thin line around the stoma.
Washing the stoma and surrounded skin in Ivory bath soap is also beneficial.
I use baby wipes with my stoma vs toilet tissue. Expensive but helpful.
As you go you will need items like Qtips; cotton pads; baby wipes; gauze pads.
You want a healthy stoma always.
Also you want items that assist in appliance application.
This is why I use the Hydrocolloid tapes.
Applying an appliance should be quick.
Good Luck
