Baclofen (Lioresal)

Street names: Lioresal, GABA-B agonist, The phenibut cousin

Baclofen (Lioresal) — 10–20 mg tablets

What it does

  • GABA-B agonist: muscle relaxant, anti-spasticity; high doses cause deep sedation
  • Off-label: alcohol-use-disorder and phenibut/GHB tapers under medical supervision

Key risks

  • ABRUPT STOP AFTER LONG USE = SEIZURES/RHABDO/psychosis — the withdrawal is genuinely dangerous and under-warned
  • Sedation, hypotension
  • Self-treating phenibut withdrawal with baclofen is real medicine — dose errors land people in hospital
  • Diversion modest but documented

Overdose signs

  • Deep sedation
  • Slow breathing
  • Hypothermia
