Dennis Quaid's twins will get 250,000 dollars each from Los Angeles' Cedars-Sinai Medical Center, as part of a settlement related to the babies' near-fatal blood thinner overdose controversy.
Bosses at the centre have agreed to pay the amount to little Thomas Boone and Zoe Grace, who had to fight for life just 12 days after they were born in 2007.
The problem occurred when a labelling mix-up led to a hospital nurse incorrectly administering an overdose of the drug Heparin to the babies.
The dispute between Quaid and his wife Kimberley Buffington and the hospital was settled last December, but lawyers for the couple insisted that that wasn't enough.
They said at the time that the babies had not recovered "completely from the effects of the injuries."
A news story published by TMZ.com says that the hospital bosses have agreed to pay up again, reports Contactmusic.
Hospital officials have also agreed to provide future medical care for the babies if it is related to any mishap on their part.
Earlier in March this year, Quaid praised Cedars-Sinai Medical Center staff for addressing the labelling problems that had resulted in the medical emergency.
Quaid and his wife have launched a campaign for better bottle-labelling systems to prevent hospital tragedies across America.
