Can I still use the standard WHO/UNICEF ORS solution containing 90 mmol/l of sodium and 110 mmol/l of glucose or should I discard it and only use the new low osmolarity ORS solution?
You should not hesitate to continue using the standard WHO UNICEF ORS (90 mEq/l of sodium with a total osmolarity of 311 mOsm/l solution), which is highly effective in the treatment of dehydration. However, because of its added advantages, WHO and UNICEF now recommend that countries use and manufacture reduced osmolarity ORS where feasible. As regards local production, the manufacture of reduced osmolarity ORS can normally be undertaken without any change in equipment or new investment in factories where standard WHO UNICEF ORS has been produced previously. As of 1 January 2003, WHO and UNICEF will begin to procure reduced osmolarity ORS for global distribution. The shelf-life of this product is assumed to be 2-3 years without any particular storage precautions. However, the old standard WHO UNICEF ORS formulation will still be available if requested .
