Although rare, sensitivity to sodium sulfacetamide may occur. Therefore, caution and careful supervision should be observed when prescribing this drug for patients who may be prone to hypersensitivity to topical sulfonamides. Systemic toxic reactions such as agranulocytosis, acute hemolytic anemia, purpura hemorrhagica, drug fever, jaundice, and contact dermatitis indicate hypersensitivity to sulfonamides. Particular caution should be employed if areas of denuded or abraded skin are involved.
FOR EXTERNAL USE ONLY. Keep away from eyes. Keep out of reach of children. Keep container tightly closed.
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. The object of this therapy is to achieve desquamation without irritation, but sodium sulfacetamide and sulfur can cause reddening and scaling of the epidermis. These side effects are not unusual in the treatment of acne vulgaris, but patients should be cautioned about the possibility.

Category C – Animal reproduction studies have not been conducted with PLEXION (sulfacetamide) Cleanser, PLEXION (sulfacetamide) Cleansing Cloths, PLEXION (sulfacetamide) SCT or PLEXION (sulfacetamide) TS. It is also not known whether these PLEXION (sulfacetamide) ® brand products can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. These PLEXION (sulfacetamide) ® brand products should be given to a pregnant woman only if clearly needed.
It is not known whether sodium sulfacetamide is excreted in the human milk following topical use of PLEXION (sulfacetamide) Cleanser, PLEXION (sulfacetamide) Cleansing Cloths, PLEXION (sulfacetamide) SCT or PLEXION (sulfacetamide) TS. However, small amounts of orally administered sulfonamides have been reported to be eliminated in human milk. In view of this and because many drugs are excreted in human milk, caution should be exercised when these PLEXION (sulfacetamide) ® brand products are administered to a nursing woman.
