Brian Keogh and Louise Doyle provide mental health nurses with guidance on recognising and managing potentially fatal adverse effects of a range of medications T keywords > drugs: adverse reactions > psychiatric disorders: drug therapy These iceywords are based on the subject headings from the British Nursing Index, This article has been subject to a double-blind review. here have been many advances in the care of people with mental health problemsin recent years. Those at the forefront of the changes have called for a reduction in the emphasis on medication-based treatments and for the introduction of more interventions based on a psychosocial approach. Despite this, psychopharmacology remains the main treatment for most people in mental distress. The role of the mental health nurse in the administration of medications has become increasingly complex, given the range of preparations available and their potential to induce adverse and toxic effects in susceptible individuals. Recognising the adverse and toxic effects of psychopharmacology is a key part of the mental heaith nurse’s role and involves assisting individuals to manage side effects which may impact on their quality of life. Occasionally, medications used in contemporary psychiatry can induce potentially lifethreatening adverse reactions in a small number of individuals. Given the idiosyncratic nature of some of these effects, and the difficulty in predicting people who are vulnerable, early 28 mental health practice march 2008 vol 11 no 6 recognition and intervention is imperative to a successful outcome should these occur. Agranulocytosi5 Agranulocytosis is a blood disorder (dyscrasia) characterised by a selective reduction in white blood cells, particularly neutrophils, resulting in an increased susceptibility to infection in those affected (Downie ef ai 2004), Rosenfeld and Loose-Mitchell (1998) suggest that blood disorders are relatively rare for clients taking anti psychotic drugs, except in the case of clozapine which may induce agranuiocytosis in up to 3 per cent of individuals taking the drug, Clozapine is classed as an atypical anti psychotic drug which is indicated in the treatment of resistant schizophrenia. Although its side effect profile is similar to conventional | anti psychotics, clozapine’s potential to induce agranulo-1 cytosis caused its removal from production in the 1970s, It t was reintroduced in the 1990s and can only be prescribed ^’ under strict supervision by the Clo2apine Patient Monitoring 5- Service. Individuals prescribed the drug must have a blood test to ensure that agranulocytosis has not occurred, then a weekly blood test for the first 18 weeks, fortnightly for up to a year, and then monthly thereafter (Healy 2005), Agranulocytosis is difficult to detect and is usually discovered when symptoms of infection appear. These symptoms include a raised temperature, sore throat and mucosal ulcers. Nurses need to watch out for these symptoms in patients taking clozapine and intervene accordingly. When detected early, intervention should only require the drug to be stopped and for symptomatic treatments to be given, such as for a sore throat or raised temperature. People who continue on anti psychotic medication, especially clozapine, after discharge from hospital should also be aware of this side effect and what to do if it occurs. Once agranucytosis has been detected, the individual’s condition should be monitored closely There is spontaneous recovery for most people within about two weeks (Downie etal 2004), mental status, fever and altered autonomic function. However, these symptoms could be indicative of changes to the client’s mental health or could have an alternative medical cause. Immediate discontinuation of the antipsychotic is essential. Pharmacological interventions include the possible use of a dopamine agonist such as bromocriptine to increase the production of dopamine and/or a muscle relaxant such as dantrolene (BNF 2007). In conjunction with this, antipyretics such as paracetamol can be given to reduce fever if indicated, Electroconvulsive therapy (ECT) may produce a rapid response to NMS and may also be beneficial for the underlying psychiatric condition (Pelonero era/1998, Healy 2005), Because of the idiosyncratic nature of NMS, prevention can be difficult as it is rarely possible to accurately predict who will develop the syndrome, Pelonero eta/(1998) identify that agitation, dehydration and a prior history of NMS are risk factors to the development of the syndrome. Therefore nurses should be familiar with a client’s previous reaction to antipsychotic medication and be aware of and respond Neuroieptic malignant syndrome Neuroleptic malignant syndrome (NMS) Is a potentially life to deficits in fluid balance in clients taking antipsychotic threatening, but relatively rare, idiosyncratic reaction to medications. neuroleptic medications. It is generally more likely to occur following the administration of high potency/low dose typical Nursing care ‘ antipsychotic such as haloperidol.

(Galbraith era/2007). Clients with NMS should be cared for in a high observation It also occurs more frequently in those who are on higher area as their physical and mental condition needs to be doses of antipsychotic medications and where polypharmacy monitored closely. Routine observations should be taken regularly and documented, with anomalies reported to the responsible medical practitioner. The client may need assistAgranulocytosis ance with activities of daily living, as well as careful use of (pictured left) appropriate interpersonal skills such reality reorientation if confusion exists. Intravenous fluids may also be needed to Individuals prescribed clozapine must have correct dehydration and electrolyte abnormalities. a blood test to eliminate agranulocytosis weekly for the first 18 weeks, fortnightly for up to a year after this initial period and then monthly thereafter Attention to nutritional support is required as many clients may not be able to eat or drink due to altered mental status. The syndrome, which usually lasts for five to seven days after drug discontinuation, may be unduly prolonged if depot antipsychotics have been used. Where possible, clients with a history of NMS should not be given antipoccurs (Healy 2005). Many clients wiil experience NMS sychotic therapy again, and should instead be prescribed shortly after initial exposure to antipsychotic medications, alternative medications such as lithium, carbamazepine or and almost all clients who develop it do so within two weeks benzodiazepines. However, this may not always be posof commencing antipsychotic medications. However, it can sible and in these cases the client should be switched to also develop in clients who have taken anti psychotics over a an antipsychotic in a different class and with a lower D2 long period of time. Diagnosis of NMS can be complicated affinity than the one which produced the NMS {for example, as it initially presents in a similar way to serotonin syndrome atypical antipsychotics). (discussed later in the article). The symptoms associated with NMS include: Serotonin syndrome LJ muscular rigidity known as ‘lead pipe’ rigidity Serotonin syndrome (SS) is a rare but life-threatening drug • tremor reaction caused by an excess of serotonin.

Treatment and prevention Early detection is essential if severe NMS is to be prevented. The symptoms associated with SS include: However, early diagnosis can be made difficult if the cardinal J jerks and twitches (myoclonus) symptom of muscle rigidity is not clearly evident.

No further lithium should raised temperature be administered and large volumes of intravenous isotonic sweating saline are usually prescribed (Healy 2005), In more severe confusion, agitation or restlessness cases, the client will need to be treated as an emergency tachycardia and may require haemodialysis (BNF 2007), hyperreflexia Individuals prescribed lithium require information about diarrhoea the drug’s actions, the side effects and intoxication and euphoria other specific information required to (Galbraith era/2007). assist the client to remain within his Knowledge and vigilant Before a diagnosis is made, at least or her therapeutic index (Downie et three major symptoms should be apparobservation for serious a/2004), This information should be ent and the client must be taking a adverse effects are essential provided in a manner that is congruent medication that affects the serotonergic with the client’s ability to understand, system.

They should also be aware of the symptoms of lithium toxicity and be advised to get medical help if they are feeling unwell, regardless of the cause. Conclusion The administration of medications is an integral part of the mental health nurses’ roles and in doing so they have a responsibility to be familiar with the preparations they administer. Imperative to this role is the careful observation of the medication’s effects and side effects, as well as educating clients to manage their medication regimes. Knowledge and vigilant observation for serious adverse effects such as the ones discussed in this article are essential if mental health nurses are to recognise, intervene and prevent fatalities that may be caused by a range of medications • Brian Keogh RPN, BNS, MSc is lecturer in mental health nursing.
