OBJECTIVE: The selective serotonin
(5-hydroxytryptamine; 5-HT) reuptake inhibitors (SSRIs) are extensively
used in the treatment of depression, panic disorder and
obsessive-compulsive disorder, and are now being evaluated in the
treatment of a number of other psychiatric disorders. The aim of this
study was to investigate the pattern of adverse reactions reported on
SSRIs in Sweden and assess possible risk factors associated with the
occurrence of adverse reactions to these agents. METHODS: A survey was
made of 1202 reports describing 1861 adverse reactions to SSRIs
submitted to the Swedish Adverse Drug Reactions Advisory Committee.
RESULTS: The most often reported adverse reactions were neurological
symptoms (22.4%), psychiatric symptoms (19.5%) and gastrointestinal
symptoms (18.0%); however, dermatological symptoms (11.4%) and general
symptoms (9.8%) were also frequent. Compared with other drugs,
gastrointestinal symptoms were more often reported for fluvoxamine,
psychiatric symptoms were more often reported for sertraline and
dermatological symptoms were more often reported for fluoxetine. In
total, the diagnoses most frequently reported were nausea (n = 139),
rash (n = 90), anxiety (n = 84), paraesthesias (n = 69), headache (n =
63) and diarrhoea (n = 63). Parkinsonism, confusion, hallucinations,
euphoria, hyponatraemia, bradycardia and hypotension were more often
reported in the elderly, whereas urticaria, akathisia, and
haematological, endocrinological, sexual and some visual reactions were
more often reported in individuals who were younger than average.
Dermatological reactions, fatigue, hyponatraemia and cough were more
common in women, whereas dyskinesias/akathisia and aggression more often
were seen in men. The median SSRI dosages were above average in patients
experiencing seizures, hypomania/mania, personality changes, malaise,
bodyweight gain, gynaecomastia and hyperprolactinaemia/galactorrhoea.
Severe symptoms, such as seizures, hyponatraemia and the serotonin
syndrome, were rarely reported. CONCLUSION: Although the design of the
study makes it difficult to draw conclusions about causality, a variety
of adverse reactions were reported. Therefore, the awareness that a
particular symptom in a patient treated with an SSRI might be an adverse
reaction should be high.
