Medication may be used to ease the physical effects of withdrawal, which include goosebumps, cramping, body aches, nausea, and intense craving. Opiate blockers and agonist/antagonist drugs may be used to alleviate the symptoms and speed up the withdrawal process and assist the addict with maintaining compliance. Methadone is used for a slow gradual withdrawal. Additional interventions are counseling, 12 step program, treatment with antidepressants and mood stabilizers.
