From the Guidelines
The next step for a patient on carbamazepine who develops dizziness and diplopia is to immediately hold or reduce the current dose and consider alternative treatments, as these symptoms may indicate carbamazepine toxicity or intolerance, particularly given the potential for dizziness as a side effect of carbamazepine treatment 1.
Clinical Considerations
When a patient on carbamazepine experiences dizziness and diplopia, it is crucial to consider the potential for carbamazepine toxicity or intolerance. According to recent guidelines, dizziness is a known side effect of carbamazepine, which can disturb daily activities 1. To minimize this adverse effect, the medication should be taken at bedtime. However, if symptoms persist, adjusting the dosage or considering alternative treatments is necessary.
Alternative Treatments
For patients who cannot tolerate the dizziness or drowsiness of carbamazepine, other voltage-gated sodium channel blockers, including lamotrigine, topiramate, and phenytoin sodium, are recommended as second-line treatments 1. The choice of alternative treatment should be individualized based on the patient's specific needs and medical history.
Monitoring and Adjustment
Regular monitoring of the patient's symptoms and adjustment of the treatment plan as needed is crucial. The patient should be assessed for other signs of toxicity or intolerance, such as ataxia, nausea, or confusion. By prioritizing the patient's safety and well-being, healthcare providers can ensure the best possible outcome and minimize the risk of adverse effects.
Key Points to Consider
- Dizziness and diplopia may indicate carbamazepine toxicity or intolerance 1
- Alternative treatments, such as lamotrigine, topiramate, and phenytoin sodium, may be necessary for patients who cannot tolerate carbamazepine 1
- Regular monitoring and adjustment of the treatment plan are crucial to ensure the patient's safety and well-being 1
From the FDA Drug Label

The patient is experiencing symptoms of dizziness and diplopia, which could be related to carbamazepine.
- The next step is to consult the healthcare provider as these symptoms may be indicative of a potential problem.
- The healthcare provider should be informed of the occurrence of these symptoms, and they will decide the best course of action, which may include adjusting the dose or monitoring the patient closely. 2

Next Steps for Patient on Carbamazepine
The patient has developed symptoms of dizziness and diplopia while on carbamazepine for bipolar disorder. The following steps can be considered:
- Monitor the patient's symptoms and adjust the dosage of carbamazepine as needed, as dizziness and diplopia are common side effects of the medication 3, 4.
- Consider alternative treatments or adjustments to the current treatment plan, as the patient may be experiencing adverse effects from the medication 5, 6.
- Evaluate the patient's overall response to carbamazepine and consider combining it with other medications, such as lithium or valproate, to achieve better treatment outcomes 7.
- Regularly monitor the patient's blood levels, liver function, and hemopoietic system to minimize the risk of serious adverse effects 5, 6.
Common Side Effects of Carbamazepine
The patient's symptoms of dizziness and diplopia are consistent with common side effects of carbamazepine, which include:
Importance of Monitoring and Adjustments
Regular monitoring and adjustments to the treatment plan are crucial to minimize the risk of adverse effects and optimize treatment outcomes for patients on carbamazepine 5, 6.
