6.3 Methods and materials for containment and cleaning up
SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational exposure or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air quality; potential migration in soil or water; effects on animal, aquatic, and plant life; and conformance with environmental and public health regulations.
7.1 Precautions for safe handling
Betamethasone tablets should be stored in well-closed containers at 2-30 °C. Betamethasone oral soln should be protected from light and stored in well-closed containers at a temp <40 °C, preferably between 15 and 30 °C. Betamethasone sodium phosphate injection should be protected from light and stored at a temp <40 °C, preferably between 15 and 30 °C; freezing should be avoided. The sterile suspension containing betamethasone sodium phosphate and betamethasone acetate (Celestone, Soluspan) should be protected from light and stored at 2-25 °C; freezing should be avoided.
7.2 Conditions for safe storage, including any incompatibilities
Betamethasone tablets should be stored in well-closed containers at 2-30 °C. Betamethasone oral soln should be protected from light and stored in well-closed containers at a temp <40 °C, preferably between 15 and 30 °C. Betamethasone sodium phosphate injection should be protected from light and stored at a temp <40 °C, preferably between 15 and 30 °C; freezing should be avoided. The sterile suspension containing betamethasone sodium phosphate and betamethasone acetate (Celestone, Soluspan) should be protected from light and stored at 2-25 °C; freezing should be avoided.
Store away from incompatible materials (see Section 10).
