Sublingual Sugar



For children suffering from severe malaria, hypoglycaemia is one of the main risk factors for a fatal outcome. There is, however, a simple, accessible solution that allows family members and health workers to save lives.

A spoonful of moistened sugar deposited under the tongue of a young child in the early hours of severe malaria can correct hypoglycaemia in record time – at home or in transit to a health centre. This is a first aid measure while waiting for emergency treatment to arrive (an infusion of glucose or stomach tube still being required if blood glucose level is not corrected by the sublingual sugar).

A clinical study was conducted by the Department of Paediatrics at Sikasso hospital in Mali in 2008, in collaboration with Antenna Technologies and the Swiss Agency for Development and Cooperation.

Conclusion: In 50% of cases, sublingual sugar can restore a normal blood glucose level in under 20 minutes. Download sublingual sugar technique flyer


1. Add a few drops of water to a teaspoonful of ordinary sugar

2. For patients who are in a coma or lying down, open the mouth by gently squeezing with the thumb and forefinger.

3. Place the sugar under the tongue. Place the patient on his/her side (in the lateral decubitus position) to prevent choking (inhalation hazard).

4. Retry after 10 minutes if the patient has not regained consciousness. Then maintain a steady supply of sublingual sugar (every 10 to 15 minutes) and supervise until stabilisation.


The administration of sublingual sugar is a real life-saving solution to remote areas where the disease is most devastating. The challenge is now to bring this process to tropical medicine specialists throughout the world, that reference books for the teaching of medicine to be updated, and that WHO and other health agencies include this process in their guidelines.

Through our efforts, this technique is now mentioned in the clinical and therapeutic guide of the organisation Médecins Sans Frontières. We are still working to its wide diffusion.
