Prescribing for Older Adults and Pregnant Women
Older adults and pregnant women are vulnerable populations that providers must take precautions when prescribing for this population. The intensity, chronicity, and co-morbidity of the mental disease, disorder, or condition should be considered together with the possibility of unfavorable medication-related outcomes when making decisions about drug selection, dosage, and duration(Rishabh, Parveen, Ravinder & Malika,2021). This paper aims to discuss about prescribing FDA-approved, off-label, and non-pharmacological interventions for depression in older adults.
Prescribing for Depression in Older Adults
Major depressive disorder, a DSM-5 diagnosis that affects older persons is the selected disorder of choice. Due to its serious consequences, late-life depression is an important public health issue and it is associated with worsened physical, cognitive, and social functioning, increased self-neglect, and an increased risk of illness, all of which are associated with an increased risk of mortality (Gabriel et al., 2020).
FDA-approved, Off label, and non-pharmacological interventions
Sertraline is a drug that has FDA approval for treating elderly patients with severe depression. A selective serotonin reuptake inhibitor (SSRI) called sertraline has antidepressant and anxiolytic effects. According to the results of several well-designed trials, sertraline (50-200 mg/day) is effective in the treatment of major depressive disorder in elderly patients (> or =60 years of age) (Gartlehner et al., 2017). The off-label drug chosen is fluoxetine, which is effective in treating dementia and depressive symptoms in elderly patients. According to Gabriel et al.,(2020), cognitive-behavioral therapy (CBT) is an effective and long-lasting treatment for late-life depression. While there is little data, CBT is also regarded to be helpful for elderly persons with anxiety issues and it is a successful and beneficial method of treating insomnia.
Risk and Benefit Assessment
Several antidepressants have shown promise in treating older people with MDD who do not exhibit psychotic symptoms. It is suggested that the optimal side effect profile and the lowest likelihood of drug-drug interactions be considered while choosing an antidepressant. Sertraline, for instance, is well tolerated by persons with cardiovascular disease because it has fewer anticholinergic effects than earlier antidepressants. Common side effects of SSRIs include nausea, dry mouth, insomnia, somnolence, agitation, diarrhea, excessive sweating, and, less frequently, sexual dysfunction (Gabriel et al., 2020). One month after starting SSRI therapy, it is crucial to check sodium levels, especially if the patient is also taking other medications that might result in hyponatremia, including diuretics (Gartlehner et al., 2017). The withdrawal symptoms associated with other SSRIs have not been described with fluoxetine. In the elderly population, fluoxetine should not be avoided and, in some circumstances, maybe the drug of choice. The SSRI fluoxetine may not be as effective in treating older patients with MDD as it is in treating younger ones.
Clinical Guidelines
As people get older, older persons experience significant losses such as losing a companion or spouse, their jobs, their social status, and their physical and mental abilities (Ruberto, Jha & Murrough,2020). Due to physiological changes brought on by advancing age, the elderly may be more susceptible to drug therapy. Patients who are older are more vulnerable to medication and may need more cautious dose adjustments. The elderly is routinely prescribed medication for a variety of causes, and drug interactions are a problem.
Tricyclic antidepressants are no longer advised as first-line treatments for older people due to the likelihood of adverse effects such as postural hypotension, which can result in falls and fractures, abnormal cardiac conduction, and anticholinergic effects(Ruberto, Jha & Murrough,2020). These latter symptoms include delirium, frequent urination, dry mouth, retention, and constipation. Tricyclic antidepressants have the potential to exacerbate a number of common medical disorders affecting the elderly, including dementia, Parkinson’s disease, and cardiovascular problems and Nortriptyline and desipramine are the best alternatives if tricyclic is used as a second-line treatment since they are less anticholinergic(Ruberto, Jha & Murrough, 2020).
When an antidepressant is chosen for an elderly patient, the first dose should be half that of a younger adult in order to minimize side effects. Elderly antidepressant side effects are probably brought on by aging-related changes in hepatic metabolism, co-occurring medical conditions, and drug-drug interactions. Instead, the intention should be to increase the dose gradually at 1- to 2-week intervals until it reaches an average therapeutic level (Gartlehner et al., 2017). Furthermore, it is now known that there are many individual variations even though the average therapeutic dose is frequently lower than that recommended for younger individuals due to how aging affects hepatic metabolism. Some patients will require a therapeutic dosage that is greater than usual.
Assume that a typical therapeutic dosage is used for 2 to 4 weeks, and no appreciable improvement is observed. The dosage should be raised until there is a clinical improvement, serious adverse effects, or until the maximum dosage is achieved (Gabriel et al., 2020). Therefore, it is essential to schedule frequent follow-up consultations to monitor therapy response, assess side effects, and modify dose as necessary. Additionally, it’s critical to watch out for any indications of depression getting worse, agitation, or anxiety, as well as the risk of suicide, particularly in the beginning stages of therapy. (Gartlehner et al., 2017). There is no evidence that antidepressant usage in the elderly causes an increase in suicidal ideation.
