What are the possible side effects of sodium chloride treatment?

Depending on the form it comes in, treatment with sodium chloride (also the chemical name for table salt) may cause side effects in some people. When taken by injection, sodium chloride may cause irritation or infection at the site of injection. If taken as a nasal spray, sodium chloride may cause sneezing, increased nasal discharge or slight stinging. In rare cases, people may have an allergic reaction to any form of sodium chloride, causing symptoms like hives, swelling in the face or throat and difficulty breathing. Talk to your doctor if you're worried about any side effects you're experiencing.
