Sodium is an essential micronutrient for muscle motility and excitability, as well as water distribution and blood volume. Its blood concentration can be measured through a blood test. Some chemotherapy drugs can cause low levels of sodium in the blood (hyponatremia), which is why you may need to be monitored during treatment. Among these medications are:

  • Vincristine;
  • Vinblastine;
  • vinorelbine;
  • Ifosfamide;
  • Cyclophosphamide;
  • Cisplatin.

A sudden drop in sodium concentration can result in symptoms such as headache, weakness, mental confusion, drowsiness and dizziness. Hyponatremia can be managed, usually by administering sodium chloride intravenous solution.
