Before using this medication, tell your doctor or pharmacist your medical history, especially of: mental/mood disorders (such as depression, psychosis, thoughts of suicide), regular/long-term use of narcotic medication. This medication is not a narcotic (morphine-like drug).

Avoid alcoholic beverages. Talk to your doctor if you are using marijuana.
