  • Receiving monoamine oxidase (MAO) inhibitors within 28 days prior to the first dose
  • A positive Hepatitis B surface antigen (HBsAg) or Hepatitis C test result
  • History of clinically significant drug allergy or history of atopic allergy (asthma, urticaria, eczematous dermatitis). A known hypersensitivity to the study drug or drugs similar to the study drug.
  • Significant illness within two weeks prior to dosing
  • Subjects who, through completion of the study, would have donated in excess of: 500 mL of blood in 14 days; 1500 mL of blood in 180 days; 2500 mL of blood in 1 year.
  • History of immunodeficiency diseases, including a positive HIV (ELISA and Western blot) test result.
  • History of drug or alcohol abuse within the 12 months prior to dosing or evidence of such abuse as indicated by the laboratory assays conducted during the screening or baseline evaluations.
  • Women of child bearing potential ( WOCBP)
  • History or presence of glaucoma or any suspicious undiagnosed skin lesions
