As part of International Internet Week of Action on Sept. 20-27, the FDA focused on websites selling unapproved versions of human growth hormone, sildenafil citrate and isotretinoin. Improper use of HGH can lead to nerve pain, elevated cholesterol or glucose levels and cancer. Sildenafil citrate tablets, used to treat erectile dysfunction, should not be used in some consumers with heart problems. And isotretinoin, used to treat severe nodular acne, can lead to severe birth defects.
The FDA is now working with its foreign counterparts to investigate websites that continue to offer unapproved or misbranded prescription medicines to U.S. consumers.
