Also seek medical attention if you experience any of the serious side effects listed here: confusion; depression; suicidal thoughts or thoughts of harming yourself; tightening of the muscles especially in the jaw or neck; speech or vision problems; fever or sweating; fast, slow or irregular heartbeat; seizures; or high-pitched sounds while breathing.
