The Higher Risk of Using Antidepressants in the Geriatric Population
Dr. Danish and his team of practitioners at Philadelphia Integrative Psychiatry are highly experienced in treating depression and other mental health concerns in the geriatric population. We ensure that our expertise remains at the cutting edge by constantly reviewing high quality research on mental health. In this blog, we delve into the specific risks associated with using antidepressants in older adults, focusing on findings from the article "The Cardiovascular Effects of Newer Antidepressants in Older Adults and Those With or At High Risk for Cardiovascular Diseases," published in 2020.
Side Effects of Antidepressants in the Elderly
When considering the safest medications for geriatric depression, several factors must be taken into account, including the potential for drug-drug interactions, side effects, and the overall health profile of the elderly patient. Here are some key points based on the provided sources:
While side effects of SSRIs and SNRIs can occur in all age groups, they are slightly more likely in the geriatric population. Most concerns are dose-dependent and generally rare, but careful monitoring is warranted to ensure safety.
Selective Serotonin Reuptake Inhibitors (SSRIs)
SSRIs are often considered the first-line treatment for depression in older adults due to their favorable safety profile and lower risk of severe side effects compared to older antidepressants. Among SSRIs, citalopram, escitalopram, and sertraline are noted for their safety and efficacy in the elderly. These medications have a lower potential for drug-drug interactions and are generally well-tolerated.
While Selective serotonin reuptake inhibitors (SSRIs) are generally considered safer compared to other antidepressants, some studies suggest they may pose cardiovascular risks in older adults. Research indicates an increased risk of cerebrovascular and coronary heart diseases in older adults taking SSRIs, but these findings may be confounded by the presence of depression itself. The challenge of "confounding by indication" makes it difficult to determine whether the observed cardiovascular risks are due to the antidepressants or the underlying depression.
Serotonin and Norepinephrine Reuptake Inhibitors (SNRIs)
SNRIs such as venlafaxine, desvenlafaxine, and duloxetine are also effective and relatively safe for treating depression in older adults. They have shown efficacy with a relatively benign adverse-effect profile. However, care must be taken to monitor for cardiac side effects such as hypertension, which can be more problematic in the elderly.
Atypical Antidepressants
Atypical antidepressants like bupropion, mirtazapine, and trazodone are also considered safe options. Mirtazapine, in particular, is beneficial for patients who also suffer from insomnia or weight loss, as it can help improve sleep and appetite[5]. Bupropion is another option that is less likely to cause sexual dysfunction, a common side effect of SSRIs and SNRIs.
Avoiding Certain Medications
Older antidepressants such as tricyclic antidepressants (TCAs) and monoamine oxidase inhibitors (MAOIs) are generally avoided in the elderly due to their higher risk of severe side effects, including cardiovascular issues and potential for lethal overdose. Additionally, medications with strong anticholinergic properties should be avoided due to the risk of cognitive impairment and falls[2][3].
Side Effects Common to All SSRIs and SNRIs
Hyponatremia: Low sodium levels can cause confusion, falls, and seizures. This is a common risk across SSRIs and SNRIs.
Gastrointestinal Issues: Nausea, dry mouth, constipation, and diarrhea are frequent side effects.
Insomnia and Anxiety: Sleep disturbances and increased anxiety may occur.
Platelet Function and Bleeding Risk: Increased risk of bleeding, especially with NSAIDs, aspirin, or anticoagulants.
Fall Risk: Dizziness and orthostatic hypotension can increase the risk of falls.
Bone Health: Long-term use may reduce bone mineral density, increasing fracture risk.
Medication Specific Side Effects
Citalopram (Celexa)
QTc Prolongation: Increased risk of cardiac arrhythmias, especially at higher doses.
Venlafaxine (Effexor) and Duloxetine (Cymbalta)
Hypertension: Can elevate blood pressure, particularly at higher doses.
Duloxetine (Cymbalta)
Hypertension: Can elevate blood pressure, particularly at higher doses.
Hepatotoxicity: Rare but severe liver damage.
Mirtazapine:
Generally safer but associated with weight gain, which could indirectly affect cardiovascular health. Of course, this increase in appetite can be beneficial for those who are losing weight.
The Importance of Careful Monitoring
Given the elevated risks, it is crucial to carefully monitor cardiovascular health in older adults prescribed antidepressants. Starting at a low dose and gradually increasing can improve tolerability. Monitoring blood pressure and ECG changes, especially after initiating or increasing doses, is recommended.
