Temasek Foundation provided StayWell Mouth Gargle free to every Singapore home under its Stay Prepared initiative, to help reduce the spread of illnesses. The mouth gargle contained 1% povidone-iodine (PVP-I), an active ingredient that is effective against a wide range of germs, including those that cause sore throat.

The StayWell Mouth Gargle was distributed on two tracks: interested households registered online for self collection, while residents living in 1 to 4-room HDB flats received one additional small 125ml bottle of mouth gargle delivered by Singapore Post to each letter box.

More than 920,000 bottles of StayWell mouth gargle were given out at the close of the exercise. This included about 780,000 bottles delivered by Singapore Post earlier in October/November 2021 to the letter boxes of all households living in 1 to 4-room HDB flats.
