According to Drugs.com, stanozolol refers to a type of man-made steroid that is the same as a natural steroid called testosterone. This drug is commonly used for treating hereditary angioedema, which is characterized by episodes of swelling on the extremities, face, throat, genitals and bowel wall.
Drugs.com explains that stanozolol can reduce the severity and frequency of episodes of swelling in angioedema but may cause severe health problems, such as liver problems, in some cases. When a person under the treatment of stanozolol experiences pain in the abdomen, dark-colored urine, nausea, light-colored stool, vomiting and yellow discoloration of the eyes, a consultation with a physician is recommended as these may be early symptoms of liver problems. Moreover, this drug can also cause birth defects, which is why women must not take this during pregnancy.
