From the Guidelines
It is generally safe to start lamotrigine (Lamictal) while tapering off citalopram (Celexa), but this should only be done under medical supervision. When initiating lamotrigine, it's crucial to start with a low dose and gradually increase it to minimize the risk of adverse effects, as noted in the clinical practice guideline for the assessment and treatment of children and adolescents with anxiety disorders 1. The guideline emphasizes the importance of caution when starting a new medication, especially when concomitantly weaning off another, to avoid potential interactions or exacerbation of symptoms.
Key considerations for this transition include:
- Gradually reducing citalopram by 10mg every 1-2 weeks to minimize withdrawal symptoms
- Initiating lamotrigine at 25mg daily for two weeks, then increasing by 25mg every two weeks until reaching the target dose (usually 100-200mg daily)
- Monitoring patients for serotonin withdrawal symptoms from citalopram reduction, such as dizziness, headaches, and flu-like symptoms
- Watching for side effects from lamotrigine, including rash, headache, dizziness, and double vision
- Informing patients to report any rash immediately, as this could indicate a serious adverse reaction to lamotrigine
The transition period typically takes 6-8 weeks to complete safely, during which time patients should be closely monitored for any adverse effects or interactions between the two medications 1. It's essential to prioritize the patient's safety and adjust the transition plan as needed to minimize potential risks.
From the Research
Starting Lamictal While Weaning Off Celexa
- The provided studies do not directly address the question of starting a patient on Lamictal (lamotrigine) while weaning off Celexa (citalopram) 2, 3, 4, 5, 6.
- However, it is known that lamotrigine is used as a maintenance therapy for bipolar disorder and has shown efficacy in delaying depressive episodes 2, 4, 5.
- When considering the use of lamotrigine, it is essential to be aware of its potential psychiatric side effects, such as affective switches, full acute psychotic episodes, and hallucinations 3.
- The dosage of lamotrigine is typically titrated over a 6-week period to 200 mg/day to minimize the incidence of serious rash 2.
- There is no direct evidence to suggest that starting lamotrigine while weaning off citalopram is contraindicated, but caution should be exercised due to the potential for interactions between the two medications.
- It is crucial to monitor the patient's condition closely and adjust the treatment plan as needed to ensure the patient's safety and well-being 4, 5, 6.
Considerations for Treatment
- Lamotrigine has been shown to be effective in preventing depressive episodes in patients with bipolar disorder 2, 4, 5.
- The medication has a relatively favorable side effect profile, but it can cause rare, life-threatening adverse effects, such as Stevens-Johnson syndrome 4.
- When using lamotrigine, it is essential to follow the recommended dosage and titration schedule to minimize the risk of adverse effects 2.
- Patients should be closely monitored for signs of psychiatric side effects, such as affective switches or psychotic episodes 3.
Monitoring and Adjustments
- Regular monitoring of the patient's condition is necessary to ensure the safe and effective use of lamotrigine 4, 5, 6.
- Adjustments to the treatment plan may be necessary based on the patient's response to the medication and the presence of any side effects.
- It is crucial to work closely with the patient to ensure that they are aware of the potential benefits and risks associated with lamotrigine treatment 2, 3, 4.
