Hi Jayne, Welcome to HealthcareMagic Forum.
How old is she? If she is less than 12 it is not Recommended. If she above 12, she can take these Lozenges safely which contain a Local Anesthetic
and a Antibiotic Specially designed for symptomatic relief from Throat Pain and Mouth Ulcers. See to it that she does not take more than 8 Lozenges in any particular day. Let her take her Medications regularly and go for regular follow up.
