The antibiotics metronids ferret dewormser and fescue will be the new drug options for flea control, according to a draft guidance released Thursday by the Food and Drug Administration.
The new guidelines provide an updated assessment of the effectiveness of three antibiotics for fleAID, and will be available for public comment for a year.
The guidance will be updated as more data becomes available.
“These drugs have the potential to reduce fleas’ susceptibility to both host and flea pathogens,” said David Ritchie, FDA deputy commissioner for regulatory affairs.
“While these drugs are currently not approved for the treatment of human fleas, this guidance will ensure that the drugs have been evaluated and approved for use in human flea treatment.”
Flea control drugs are a form of treatment for fleabites, which are fleas that have bitten humans and are spread from person to person through direct contact.FEMA’s guidance is designed to give patients the information they need to make the best decisions for flease control.
Flea-infected people can take the antibiotics, but they also need to take flea-specific anti-bacterial tablets or spray once daily for the duration of the fleas infection.
The drug is generally taken in a spray or capsule form.
The FDA said these are the recommended dose and duration for treatment of fleas in the United States.
The FDA recommends that people start taking these medications within six to eight weeks of a flea bite.
The fleas usually are gone within six hours or less, and they will eventually die.
The antibiotics are also effective for treating some types of parasites, such as mites, but people who get a severe infection or who are pregnant or nursing are at a higher risk of getting a severe reaction to the medication.
The drug has the potential for a significant impact on fleas because they carry fleas-specific genes.
The drugs are approved to treat fleas of humans and animals, but the FDA said they should be used to treat all fleas.
