The entertainer, whose real name is Byiome Muir, was admitted on Thursday to a hospital in, Kingston.
A source close to the entertainer told THE STAR that I-Octane fell ill after catching the common cold last week.
In a release issued yesterday, the entertainer's management team said, "He is now under the care of his physician and though recuperating, he has been advised by his doctor to rest until further reassessment."
The release further noted that I-Octane was expected to make a full recovery based on discussions with his doctor, however, he would be unable to honour some of the commitments previously scheduled.
The deejay will miss commitments in the Turks and Caicos Islands and Negril and Manchester in Jamaica.
I-Octane, who recently performed at the reggae festival Reggae Sumfest in Catherine Hall, Montego Bay, has been having a good year with songs such as My Story and Jiggle fi Mi. He also released his debut album, Crying to the Nation, earlier this year.
