From the Guidelines
Treatment for essential tremor should start with propranolol, a beta-blocker that has been used for over 40 years to effectively manage symptoms, as indicated by recent studies 1. When considering treatment options for essential tremor, it's crucial to weigh the benefits and potential side effects of each approach.
- Medications are a primary treatment option, with propranolol being a first-line choice due to its long history of use and effectiveness in reducing tremor amplitude.
- The dosage of propranolol can vary, but it is typically started at a low dose and adjusted based on patient response and tolerance, with a range of 20-320 mg daily.
- Other beta-blockers, such as metoprolol, may also be considered depending on the individual case and medical comorbidities, as suggested by studies on individualized treatment approaches 1.
- Non-medication approaches, including lifestyle modifications and physical therapy, can also play a role in managing essential tremor symptoms, such as avoiding tremor-triggering substances and using weighted utensils.
- In severe cases where medications are ineffective, surgical interventions like deep brain stimulation may be considered, but these are typically reserved for patients with significant disability due to their tremor.
- Ultimately, treatment should be tailored to the individual patient, taking into account the severity of their tremor, its impact on daily activities, potential medication side effects, and patient preferences.

Treatment Options for Essential Tremor
The treatment options for essential tremor can be categorized into pharmacological and surgical interventions.
- Pharmacological interventions:
- Propranolol and primidone are classified as clinically useful for limb tremor 2, 3, 4, 5, 6
- Topiramate is considered clinically useful for doses higher than 200 mg/day 2, 3, 6
- Alprazolam and botulinum toxin type A are classified as possibly useful 2, 3, 4, 6
- Other agents such as ethanol, benzodiazepines, gabapentin, levetiracetam, and zonisamide may be effective 5
- Surgical interventions:
- Unilateral Ventralis intermedius thalamic DBS, radiofrequency thalamotomy, and MRI-guided focused ultrasound thalamotomy are considered possibly useful for limb tremor 2, 4, 6
- Deep brain stimulation and thalamotomy are highly efficacious in reducing tremor, but carry a small risk of major complications 4, 6
Treatment Approach
The treatment approach for essential tremor depends on the tremor severity, location, and risk-benefit ratios 5. Mild to moderate tremor usually responds to oral agents, while severe tremor may require surgical intervention 5. The treatment of essential tremor may also involve a combination of pharmacological and surgical interventions, and the choice of treatment should be guided by the patient's individual needs and preferences 2, 3, 4.
Future Directions
Future alternative therapeutic options for essential tremor may include T calcium channel blockers, modulators of GABAA receptors, GABAB receptors, and glutamatergic neurotransmission, and drugs that decrease the expression of LINGO-1 3. However, further research is needed to determine the efficacy and safety of these potential treatments.
