Hi and sorry about what you are going through. You carry solucortel just in case you need some more steroid hormones to cope with stressful situations. The body normally increases the production of steroid hormones during stress. because you have addison disease, this is impossible for you and we will need the external administration of this. You may need this in situations like an accident, loss of a dear one, going through some very difficult moments, severe illness etc. Getting a new one is best from a pharmacy..However, you may use any syringe if you must use it now and there is no other way of getting around the problem. I strongly recommend that you do all to get the advised syringe as soon as possible, too. Wish you a good health. All the best in all your endeavors to get the new syringe.
