The spray saline, the eye drop saline, and the nasal saline all have a number of other ingredients in them including various preservatives. I did not buy any of them because I didn't want any of the other ingredients passing into my body.

I spoke with the pharmacist about this. He told me that in order to get pure saline- the kind used for wound irrigation or the kind used in IVs- I would have to get a prescription. I protested about this knowing that normal saline is just water and salt. He said that was state law. I asked if he, as a pharmacist, could prescribe it for me. He said in the state I live in, pharmacists aren't allowed to prescribe anything. In other states, pharmacists can prescribe. (I'm getting used to frustration.)

So my dear husband, quite on his own, found unadulterated saline (the kind I would have needed a prescription for at the pharmacy) on Amazon. I ordered it up without any difficulties.

I don't know if all of the preservatives should be a concern but I assume that is one of the reasons the medical field uses the saline that does not have the additional ingredients on patient's open wounds.

Don't know if I'm making unreasonable assumptions but I figure if it's my brain I'm working with, I'd better be extra careful. That's also why I don't use my tap water because it comes from the well and I'm not sure what's in it (our area is known for high levels of arsenic).

Perhaps I'm being overly cautious...
