In the new programme, Lemon is set to become a modern day 'Jim'll Fix It' character, when he and celebrity helpers will meet people with problems, and try to help them and make their dreams come true.
Lemon's switch to ITV1 follows his ITV2 game show 'Celebrity Juice', with team captains Holly Willoughby and Fearne Cotton, recording the highest audiences of any TV programme on digital TV in 2011.
The sponsorship was planned and bought by WPP media agency MediaCom and the idents were made by Kream.
Rose Gray, senior brand manager, Panadol, said: "Panadol comes to the aid of UK consumers with its pain relief, so linking to Keith Lemon's 'LemonAid', where Keith also provides aid to the public in his own unique way, is a great fit."
The 45-minute programme starts on Saturday 7 April at 6.15pm and will run for six weeks.
Dani Roe, account sales manager, ITV, said: "Keith Lemon appeals to a mass audience and we are delighted to welcome him to our flagship channel, ITV1.
"We believe that Panadol is the perfect sponsor for the new programme, Keith Lemon's 'LemonAid', and hope that it will be a great platform for the brand to reach its core target audience."
