General
Wash hands immediately after applying amlexanox oral paste,
5%, directly to ulcers with the finger tips. In the event that a rash or
contact mucositis occurs, discontinue use.
Carcinogenesis, Mutagenesis, Impairment of Fertility
Amlexanox was not carcinogenic when administered orally to
rats for two years and to mice for 18 months. In vitro (Ames) and in vivo
(mouse micronucleus) mutagenicity tests of amlexanox were negative. Amlexanox
at doses up to two hundred times the projected human daily dose, on a mg/m²
basis, did not significantly affect fertility or general reproductive
performance in rats.
Pregnancy Category B
Teratology studies were performed with rats and rabbits at
doses up to two hundred and six hundred times, respectively, the projected
human daily dose, on a mg/m² basis. No adverse fetal effects were observed. At
doses up to two hundred times the projected human daily dose, on a mg/m² basis,
amlexanox did not have significant effect on peri- and postnatal development of
rat fetuses. There are no adequate and well-controlled studies in pregnant
women. Because animal reproduction studies are not always predictive of human response,
this drug should be used during pregnancy only if clearly needed.
Nursing Mothers
Amlexanox was found in the milk of lactating rats;
therefore, caution should be exercised when administering amlexanox oral paste,
5%, to a nursing woman.
Pediatric Use
Safety and effectiveness of amlexanox oral paste, 5%, in
pediatric patients have not been established.
Geriatric Use
Clinical studies of Aphthasol (amlexanox) did not include sufficient
numbers of subjects aged 65 and over to determine whether they respond
differently from younger subjects. Other reported clinical experience has not
identified differences in responses between the elderly and younger patients.
In general, dose selection for an elderly patient should be cautious, usually
starting at the low end of the dosing range, reflecting the greater frequency
of decreased hepatic, renal, or cardiac function, and of concomitant disease or
other drug therapy.
