When administered as an injection, the dosage and duration of treatment with NaCl depend on the condition being treated and the patient’s needs. The usual dosage for adults varies widely depending on the purpose of administration.
As with any medication or solution, NaCl may cause side effects in some people. Common side effects may include redness, swelling, or pain at the injection site. In rare cases, more serious side effects such as allergic reactions or electrolyte imbalances may occur.
