From the Guidelines
For patients with vertigo who require antiplatelet therapy, clopidogrel 75 mg daily is a reasonable option. This recommendation is based on the guidelines for the prevention of stroke in patients with stroke or transient ischemic attack, which suggest that clopidogrel monotherapy is an acceptable option for initial therapy 1. Unlike aspirin, clopidogrel may cause fewer vestibular side effects and may be better tolerated in patients with pre-existing vertigo. Some key points to consider when selecting an antiplatelet agent for patients with vertigo include:
- The selection of an antiplatelet agent should be individualized on the basis of patient risk factor profiles, cost, tolerance, and other clinical characteristics 1
- Aspirin (50 mg/d to 325 mg/d) monotherapy, the combination of aspirin 25 mg and extended-release dipyridamole 200 mg twice daily, and clopidogrel 75 mg monotherapy are all acceptable options for initial therapy 1
- The addition of aspirin to clopidogrel increases the risk of hemorrhage and is not recommended for routine secondary prevention after ischemic stroke or TIA 1 Before starting any antiplatelet therapy, it is essential to assess the patient's bleeding risk and consider starting at a lower dose with gradual titration to minimize side effects. The choice should ultimately be individualized based on the specific cause of vertigo, the indication for antiplatelet therapy, comorbidities, and potential drug interactions. Regular follow-up is essential to monitor both vertigo symptoms and the effectiveness of the antiplatelet therapy.

From the Research
Antiplatelet Therapy for Patients with Vertigo
There are no direct research papers to assist in answering this question. However, we can look at the available evidence on antiplatelet therapy and its effects on various conditions.
Available Antiplatelet Therapies
- Aspirin is a commonly used antiplatelet agent, and its efficacy in preventing cardiovascular events has been established 2, 3.
- Clopidogrel is another antiplatelet agent that has been shown to be effective in preventing cardiovascular events, but its use with proton pump inhibitors (PPIs) may increase the risk of recurrent cardiovascular events 4.
- Ticagrelor is a newer antiplatelet agent that has been shown to be effective in preventing thromboembolic complications in patients undergoing intracranial stenting procedures 5.
- Dual antiplatelet therapy (DAPT) with aspirin and clopidogrel or ticagrelor may be effective in preventing thromboembolic complications, but the choice of agent depends on various factors, including the patient's condition and the procedure being performed 5.
Considerations for Patients with Vertigo
- There is no direct evidence on the use of antiplatelet therapy in patients with vertigo.
- However, patients with vertigo may be at risk of cardiovascular events, and antiplatelet therapy may be beneficial in preventing these events.
- The choice of antiplatelet agent and the duration of therapy should be individualized based on the patient's condition and other factors, such as the presence of gastrointestinal bleeding or other comorbidities 4, 6.
