From the Guidelines
For a geriatric patient with OCD who believes her clothes are wet when they aren't and is not responding to sertraline 75mg daily, I would recommend increasing the sertraline dose to 100-200mg daily, as higher doses are often needed for OCD symptoms, as suggested by the treatment algorithm for OCD 1. Alternatively, augmentation strategies could be considered, such as adding a low-dose antipsychotic like risperidone (0.25-1mg daily) or aripiprazole (2-5mg daily) to address the fixed belief about wet clothing, which has delusional qualities, as supported by the use of antipsychotics in treatment-resistant OCD 1. Some key points to consider when treating geriatric patients with OCD include:
- Gradually increasing doses (e.g., sertraline by 25mg increments every 1-2 weeks) to minimize side effects
- Monitoring closely for side effects like falls, hyponatremia, and QT prolongation
- Implementing cognitive behavioral therapy specifically designed for OCD alongside medication adjustments, as combinatorial therapy has been shown to be effective in patients with treatment-resistant OCD 1
- Regular reassessment of both benefits and side effects is essential in this vulnerable population The belief about wet clothing may represent both OCD and possibly a somatic delusion, which explains why an antipsychotic augmentation might be particularly helpful in this case, as antipsychotics have been used to treat delusional symptoms in geriatric patients 1.
From the Research
Medication for Geriatric Patient with OCD
The patient is currently taking sertraline 75mg qd, but the behavior of thinking her clothes are wet even though they are not, and getting upset, still persists.
- The current dosage of sertraline may not be sufficient to address the patient's OCD symptoms, as studies have shown that higher doses of sertraline may be more effective in treating OCD 2.
- A study found that increasing the dose of sertraline to between 250 and 400 mg/day resulted in significantly greater symptom improvement compared to a dose of 200 mg/day 2.
- However, it's also important to consider the potential risks of increasing the dose, as higher doses of sertraline may increase the risk of adverse reactions 3.
- The patient's age and potential interactions with other medications should also be taken into account when considering a dose increase, as older adults may be more susceptible to adverse effects 4, 5, 6.
- There is no clear evidence to suggest that the patient's current dosage of sertraline is ineffective due to an interaction with another medication, but it's still important to monitor for potential interactions and adjust the dose accordingly 5, 6.
Potential Next Steps
- Consider increasing the dose of sertraline to a higher dose, such as 200 mg/day or more, under close monitoring for potential adverse effects 2, 3.
- Monitor the patient's response to the increased dose and adjust as needed to minimize adverse effects and maximize efficacy.
- Consider consulting with a specialist or conducting further research to determine the best course of treatment for the patient's specific condition.
