Description

Background Functional somatic disorders (FSD) are characterized by specific patterns of persistent physical symptoms with a complex etiology involving a multiform interplay between physiological, psychological, and socio-cultural factors. Patients with FSD are prevalent in all medical settings and receive diagnoses such as fibromyalgia, chronic fatigue syndrome, irritable bowel syndrome, and other functional somatic syndromes (FSS) depending on which medical specialty they consult. Multisystem FSD describes a severely affected subgroup of patients who suffer from symptoms from multiple orga...

  • * Use of efficient contraception for women in the fertile age (contractive pills, intrauterine device, deposit injections of gestagen, subdermal implant, hormone vaginal ring, or transdermal deposit plaster)
  • * Men with a pregnant or non-pregnant female partner in the fertile age must use a condom in the full length of the trial plus a minimum of one week after end of study drug treatment

  • * Sweat gland disorder (risk of hyperthermia in high temperatures related to use of benztropine)
  • * Current pregnancy or lactation
  • * Concomitant use of CNS-acting drugs (drugs with pain-modulating or antidepressant properties and others) besides paracetamol and ibuprofen (escape medication in restricted doses).
