After assessing and diagnosing a patient, PMHNPs must take into consideration special characteristics of the patient before determining an appropriate course of treatment. For pharmacological treatments that are not FDA-approved for a particular use or population, off-label use may be considered when the potential benefits could outweigh the risks. In this Discussion, you will investigate a specific disorder and determine potential appropriate treatments for when it occurs in an older adult or pregnant woman.
Introduction
When treating patients with mental health disorders, Psychiatric Mental Health Nurse Practitioners (PMHNPs) must consider several factors, including the characteristics of the patient and the available treatment options. This discussion focuses on the situation where pharmacological treatments that are not FDA-approved for a specific use or population are considered, such as when treating older adults or pregnant women. In such cases, off-label use of medications might be necessary and seen as potentially beneficial, despite potential risks.
Disorder in Older Adults: Major Depressive Disorder
Major Depressive Disorder (MDD) is a psychiatric disorder characterized by persistent feelings of sadness, loss of interest or pleasure, changes in appetite and sleep patterns, and a range of other symptoms that significantly impair daily functioning. While MDD can affect individuals of any age, it is particularly prevalent in older adults. The prevalence rates of depression in older adults are estimated to be around 1-5% for community-dwelling individuals and up to 13.5% for those in residential care settings (Bharath et al., 2019).
Considering the unique characteristics of older adults, treatment for MDD in this population should be approached with caution. There are several pharmacological options available to treat MDD, including selective serotonin reuptake inhibitors (SSRIs), serotonin-norepinephrine reuptake inhibitors (SNRIs), tricyclic antidepressants (TCAs), and others. However, PMHNPs must consider the potential risks and benefits of these medications in older adults due to age-related physiological changes and the increased likelihood of comorbid medical conditions.
For example, SSRIs are commonly used in the treatment of MDD due to their favorable side effect profile and safety profile compared to other classes of antidepressant medications. However, PMHNPs must be cautious when prescribing SSRIs in older adults, as elderly individuals may have altered drug metabolism and clearance, potentially leading to increased drug levels and side effects. Additionally, certain SSRIs may have anticholinergic properties, which can exacerbate cognitive impairment, dry mouth, and constipation, commonly observed in older adults. This warrants close monitoring of elderly depressed patients and modification of the treatment plan as necessary.
Another consideration when treating MDD in older adults is the presence of comorbid medical conditions. Elderly individuals often have multiple medical conditions, such as cardiovascular disease, diabetes, or neurodegenerative disorders. PMHNPs must be aware of potential drug-drug interactions between antidepressants and medications used to manage these comorbidities. For example, SSRIs and SNRIs can increase the risk of bleeding when used with nonsteroidal anti-inflammatory drugs (NSAIDs) or anticoagulants, commonly prescribed for cardiovascular conditions. Close collaboration with other healthcare providers and careful review of medications is crucial to ensure the safety and effectiveness of treatment in older adults.
Disorder in Pregnant Women: Generalized Anxiety Disorder
Generalized Anxiety Disorder (GAD) is characterized by excessive and uncontrollable worry, often accompanied by physical symptoms such as restlessness, muscle tension, irritability, and difficulty concentrating. Pregnancy can be a challenging period for women, both physically and psychologically, and may exacerbate symptoms of GAD or even trigger the onset of the disorder. Pregnant women with GAD require specialized treatment considerations to ensure the well-being of both the mother and the developing fetus.
When considering pharmacological interventions for pregnant women with GAD, PMHNPs must first consider the potential risks and benefits of medication use during pregnancy. The primary goal is to balance the potential benefits to the mother against potential risks to the fetus. Many psychotropic medications cross the placenta, potentially affecting fetal development, and thus, the principles of off-label use must be carefully evaluated.
One class of medications commonly used to treat GAD is selective serotonin reuptake inhibitors (SSRIs), such as sertraline and escitalopram. These medications have been commonly prescribed in non-pregnant individuals and have shown efficacy in the treatment of GAD. When considering the use of SSRIs during pregnancy, PMHNPs must weigh the potential risks associated with fetal exposure to these medications against the risks associated with untreated maternal anxiety. Several studies have found an association between SSRI use in pregnancy and adverse neonatal outcomes such as preterm birth, low birth weight, and neonatal withdrawal symptoms (Yonkers et al., 2011). However, it is important to note that the absolute risk of these adverse outcomes is generally low, and the risks associated with untreated maternal anxiety should also be considered.
