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 the reach of children. Keep containers tightly closed
General: 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 epidermis. These side effects are not unusual in the treatment of acne vulgaris, but patients should be cautioned about the possibility.
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 AVAR Gel, AVAR Green or AVAR Cleanser. It is also not known whether AVAR Gel, AVAR Green or AVAR Cleanser can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. AVAR Gel, AVAR Green and AVAR Cleanser should be given to a pregnant woman only if clearly needed.
Nursing Mothers: It is not known whether sodium sulfacetamide is excreted in the human milk following topical use of AVAR Gel, AVAR Green, or AVAR Cleanser. 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 AVAR Gel, AVAR Green, or AVAR Cleanser are administered to a nursing woman.
Pediatric Use: Safety and effectiveness in children under the age of 12 have not been established.
