Hello, I currently have a blocked right ear because of some wax buildup. I have Sodium Chloride Injection 0.9% little contained packages next to me and i ve read that sodium chloride can be used to drop into the ear to help dissolve the wax. However i don t know if this is the right drops to use. The description of the drops reads: Sodium Chloride Injection 0.9% is a sterile isotonic solution of sodium chloride in Water for Injections, pH 4.5 - 7.0, containing no preservatives (normal saline). Is this safe to use to remove my ear wax?
