Exclusive | Parents are swapping leucovorin for…
Parents are scrambling to secure a low-cost generic cancer drug for their youngsters after the Trump administration touted it as a potential treatment for autism symptoms in the autumn.
“I can’t even tell you how much of an influx we’ve had,” Dr. Richard Frye, a pediatric neurologist who research the medication, called leucovorin, told The Post. “We can’t schedule anymore patients until 2028.”
Now, with the drug out of attain, some mother and father are turning to over-the-counter folic acid dietary supplements, which they hope can serve as a substitute — but the transfer, Frye warned, “may do more harm than good.”

What does folate have to do with autism?
Leucovorin is a prescription drug that has historically been used to defend healthy cells during chemotherapy. It’s a type of folate, or vitamin B9, an important nutrient our our bodies need but can’t produce on their own.
Folate is essential for mind development. Research has discovered that some youngsters with neurodevelopmental issues, including autism, have low ranges in their brains — a condition called cerebral folate deficiency.
This deficiency is often triggered by autoantibodies that block folate from reaching the mind. One research discovered that more than 75% of youngsters with autism carry these antibodies, in contrast with just 10-15% of children without the disorder.
Intrigued, Frye started exploring whether or not leucovorin might bypass this blockage and ship folate immediately to the mind, doubtlessly easing symptoms in some youngsters with autism.
In a 2012 scientific trial, he discovered that about one-third of youngsters with autism who took the drug twice daily confirmed vital enhancements in speech and language. Side results like hyperactivity resolved shortly, and no critical hostile occasions had been reported.
Fast ahead to September, when federal health officers announced they might update leucovorin’s label to permit its use for youngsters with “cerebral folate deficiency and autistic symptoms,” citing research like Frye’s.

President Trump even called leucovorin an “amazing” drug and touted it as a potential “answer to autism.” But Frye cautions that it’s not a miracle treatment.
“If you’re going to the doctor looking for an autism pill, it doesn’t exist,” he told The Post in March. “But leucovorin has helped a lot of children.”
The Autism Science Foundation doesn’t endorse leucovorin as a treatment for autism, saying in a assertion that “more studies are necessary before a conclusion can be reached.”
Still, the announcement — along with tales of beforehand nonverbal youngsters seemingly beginning to communicate in a single day after taking the drug — sparked a rush of mother and father attempting to get it.
But the boundaries to access are high. Some, determined, have turned to folic acid, a type of vitamin B9 bought over the counter. But Frye warned this is just not a substitute.
Why folic acid dietary supplements are not the same at leucovorin
“People don’t understand that vitamins are very complex chemicals and treatment with them is not that simple,” Frye said. “What you’re giving, it’s just like a drug.”
Though both leucovorin and folic acid are kinds of B9, there’s a essential distinction. Leucovorin is an lively type that the physique can use immediately, while folic acid is artificial and must be transformed first.
“Our bodies can only activate about 400 micrograms a day, which is what is in your standard or a little even high dose multivitamin, so that’s OK,” Frye explained.

Leucovorin doses, by distinction, are in milligrams — far larger than commonplace folic acid dietary supplements.
“I have had parents who’ve gone to neurologists and had the neurologist tell them that [leucovorin] is just like folic acid, so just take a lot of it,” Frye said. “You can’t do that.”
Why is an excessive amount of folic acid a unhealthy factor?
Too a lot folic acid can overwhelm the physique’s conversion course of, leaving unmetabolized folic acid in the blood. In pregnant girls, Frye said, research recommend this might increase the risk of autism in their youngsters.
For children with cerebral folate deficiency and autism, he explained, “we think that the folic acid will essentially plug the transporter,” making it even tougher for the nutrient to attain the mind.
“We actually recommend no folic acid for them,” Frye added, Frye added, noting that while the data isn’t definitive, it might doubtlessly worsen their autism symptoms, including behavioral challenges.
“Folic acid is good to a point, like in your everyday regular supplement. But if you need higher doses of folate because of a folate deficiency or other metabolic issues, you can’t use folic acid,” Frye careworn. “Actually, you may do more harm than good.”
