Valium, known generically as diazepam, is widely prescribed across the U.S. to treat conditions like anxiety, muscle spasms, and seizures. Introduced in the 1960s, it has become a staple in managing stress and panic disorders. However, due to its potential for dependence, the DEA classifies it as a Schedule IV controlled substance, meaning it has accepted medical use but also some risk of abuse. Its long-lasting effects make it a preferred choice for certain anxiety treatments in the U.S. healthcare system.
