Florida teacher Tamara Drock, 47, died on Friday (local time) after spending 12 weeks in hospital with Covid complications.
In October, her husband, Ryan, sued the Palm Beach Gardens Medical Centre after they refused to treat her with the drug.
Ivermectin is approved to treat parasitic worms, but has not been proven to help patients with Covid-19.
According to The Washington Post, Palm Beach County Circuit Judge James Nutt rejected Mr Drock’s lawsuit last month, saying allowing judges to countermand doctors’ decisions could set a dangerous precedent. He instead encouraged the family to reach an agreement with the hospital.
Family said amount administered was 'too low'
Ms Drock was intubated and placed on a ventilator after her condition declined.
Doctors at the hospital eventually agreed to administer the drug, but the family's attorney said the dosage was too low, The Palm Beach Post reported.
Ms Drock, who died on November 12, leaves behind a 14-year-old daughter, Emily, and a 12-year-old son, Parker.
In an interview with the Palm Beach Post on Monday, Mr Drock blamed the hospital for Tamara’s death and has filed an appeal, The Independent reported.
“I’m hoping they name a law after her so no one has to go through this,” he told the publication.
"We don’t know if [the drug] would have saved her life, but it could have. Maybe it wouldn’t have done anything, but we’re pursuing the case strictly from a legal perspective.
"Every person in Florida has a constitutional right to choose what is done with their own body."
Mr Drock also tested positive for Covid, but recovered.
