Babyshambles postponed its five remaining dates to allow Doherty's "excellent" efforts at overcoming his addiction to continue, EMI said.
Last month Doherty, in court on drugs charges, avoided jail after a judge said she was "impressed" with his attempts to beat his addiction.
The singer had pleaded guilty to five counts on possessing heroin, cocaine and cannabis. He was allowed to continue his drug treatment and told he would be sentenced in December.
The EMI announcement canceled concerts in Glasgow, Nottingham, Manchester and Newcastle.
"The band apologizes to fans but hopes that they will understand the importance of Peter being able to best continue his good progress in recovering from addiction," EMI said. "The dates will be rearranged for as soon as possible and all tickets will remain valid."
