Notes
[edit]- ^ Data on the exact incidence of the different adverse effects is greatly lacking so only rough approximations of adverse effect incidence is available
- ^ Refer to main text below for details on this adverse effect
- ^ A drop in blood pressure that results from standing up
- ^ A disturbance in the electrical cycle of the heart
- ^ Elevated serum levels of the lactation-related hormone prolactin. This in turn can result, in the short term, at least, in galactorrhoea (lactation that is unrelated to pregnancy or breastfeeding), gynaecomastia (swollen breast tissue), sexual dysfunction and amenorrhoea (the absence of the menstrual period in women). Whereas in the long-term hyperprolactinaemia can result in osteoporosis (brittle bones).
- ^ An impaired ability to regulate one's body temperature
- ^ High blood glucose (sugar) levels
- ^ The hypothalamus of the brain regulates the release of a number of hormones as well as a few "housekeeping" functions such as tight control over body temperature
- ^ Widening (dilation) of the pupils
- ^ Refer to the text below for details
- ^ Constriction of the pupils of the eyes
- ^ Being unable to pass urine
- ^ Glucose (sugar) in the urine due to there being too much glucose in the blood for the kidneys to reabsorb it all when filtrate goes through loop of henle in the nephrons of the kidney.
- ^ Low blood glucose (sugar)
- ^ Basically an exaggerated form of leucopaenia. It occurs when the white blood cell (WBC) count drops below 5% of the norm
- ^ Where the number of red blood cells of the body die breakdown to an abnormal extent. These cells carry oxygen across the body from the lungs
- ^ Where the bone marrow stops adequately (in order to replenish the blood cells that die off every day) producing new blood cells
- ^ An abnormality in the electrical activity of the heart which can lead to potentially fatal changes in heart rhythm
- ^ Dangerously (in the short-term) high blood pressure
- ^ A dangerous skin reaction
- ^ An autoimmune reaction
- ^ A potentially fatal collection of symptoms (i.e. syndrome) that results from an abnormally excessive release of antidiuretic hormone (ADH). This in turn increases the reabsorption of
- ^ A potentially fatal condition that is caused by dopamine receptor-blocking agents such as antipsychotics. It develops over a period of days or weeks and is characterised by rigidity, tremor, diarrhoea, tachycardia, altered mental status (e.g. confusion, mania, hallucinations, etc.) and hyperthermia (high body temperature)
- ^ An autoimmune condition in of which the body's defences attack the neuromuscular junction – the gap between muscle and nerve cells across which the nerves send messages to the muscle cells
- ^ An abnormally low number of white blood cells in the blood. These cells defend the body from infections and hence this can heighten one's risk of infections
- ^ An abnormally high number of eosinophils – the cells of the immune system that defends the body from parasites
- ^ An abnormally low number of all three major groups of blood cells including the red blood cells, white blood cells and platelets
- ^ A painful and sustained (usually a few hours) erection
- ^ Fear of light
- ^ A reduction in the normal homeostatic breathing reaction to reductions in plasmacarbon dioxide levels
- ^ High body temperature
- ^ Low body temperature
- ^ Lactation that is unassociated with lactation or breastfeeding
- ^ The accumulation of fluid in the tissues of the brain
- ^ Basically the opposite to euphoria
- ^ The absence of menstrual periods
- ^ An often irreversible and sometimes even fatal movement disorder characterised by involuntary, repetitive and purposeless movements of the face, extremities, lips or tongue. Usually takes a number of years to develop but in some it can appear within months or less since the initiation of antipsychotic treatment
