PRECAUTIONS
General
For external use only. Keep away from eyes. If irritation develops, use of
the product should be discontinued and appropriate therapy instituted. Patients
should be carefully observed for possible local irritation or sensitization
during long-term therapy. Hypersensitivity reactions may occur when a sulfonamide
is readministered irrespective of the route of administration, and cross-sensitivity
between different sulfonamides may occur. Sodium sulfacetamide can cause reddening
and scaling of the skin. Particular caution should be employed if areas of involved
skin to be treated are denuded or abraded.
Keep out of the reach of children.
Carcinogenesis, Mutagenesis and Impairment of Fertility
Long-term studies in animals have not been performed to evaluate carcinogenic
potential.
Pregnancy
Category C: Animal reproduction studies have not been conducted
with Klaron® (sodium sulfacetamide lotion) Lotion. It is also not known whether Klaron (sodium sulfacetamide lotion) Lotion can cause
fetal harm when administered to a pregnant woman or can affect reproduction
capacity. Klaron (sodium sulfacetamide lotion) Lotion should be given to a pregnant woman only if clearly
needed.
Kernicterus may occur in the newborn as a result of treatment of a pregnant
woman at term with orally administered sulfonamide. There are no adequate and
well controlled studies of Klaron (sodium sulfacetamide lotion) Lotion in pregnant women, and it is not known
whether topically applied sulfonamides can cause fetal harm when administered
to a pregnant woman.
Nursing Mothers
It is not known whether sodium sulfacetamide is excreted in the human milk
following topical use of Klaron (sodium sulfacetamide lotion) Lotion. Systemically administered sulfonamides
are capable of producing kernicterus in the infants of lactating women. Small
amounts of orally administered sulfonamides have been reported to be eliminated
in human milk. Because many drugs are excreted in human milk, caution should
be exercised in prescribing for nursing women.
Pediatric Use
Safety and effectiveness in pediatric patients under the age of 12 have not
been established.
