Key points

  • Extra tablets are not a safe response to swelling or a high blood-pressure reading without clinical direction.
  • Vomiting, diarrhoea, poor intake or heat can increase dehydration and kidney risk.
  • Low sodium, potassium or magnesium can cause weakness, confusion, cramps or abnormal rhythm.

Listings are for comparison only; suitability and supply depend on indication, prescription, laboratory monitoring and pharmacy checks.
