in patients aged 6 months and older.
Ivermectin was approved as a prescription treatment for head lice in February 2012, according to an FDA press release, and is now approved as an over-the-counter treatment through an “Rx-to-OTC” switch process. The approval was granted to Arbor Pharmaceuticals.
The expanded approval for ivermectin increases access to effective care for head lice, which is estimated to affect between 6 million and 12 million children each year in the United States, according to the Centers for Disease Control and Prevention.
“The Rx-to-OTC switch process aims to promote public health by increasing consumer access to drugs that would otherwise only be available by prescription,” Theresa Michele, MD, acting director of the Office of Nonprescription Drugs in the FDA’s Center for Drug Evaluation and Research, said in the press release.
The FDA also noted in the press release that “Sklice, and its active ingredient ivermectin, have not been shown to be safe or effective for the treatment or prevention of COVID-19 and they are not FDA-approved for this use.”
The drug is approved only for treating head lice, and should be used on the scalp and dry hair, according to the labeling. In the wake of the approval, ivermectin will no longer be available as a prescription drug, according to the FDA, and patients currently using prescription versions should contact their health care providers.
An Rx-to-OTC switch is contingent on the manufacturer’s data showing that the drug is safe and effective when used as directed. In addition, “the manufacturer must show that consumers can understand how to use the drug safely and effectively without the supervision of a health care professional,” according to the FDA.
