What is the recommended dosage of Propranolol for treating essential tremor?

Start with 40 mg
Start with 80 mg
Start with 120 mg
Start with 160 mg

The correct answer is: Start with 40 mg

The recommended starting dosage of Propranolol for treating essential tremor is 40 mg. This dosage is typically initiated to evaluate the patient's response to the medication and to minimize the risk of side effects. Propranolol is a non-selective beta-blocker, and when used for essential tremor, it can help to reduce the frequency and amplitude of tremors by affecting the beta-adrenergic receptors in the central nervous system. Starting at 40 mg allows for a careful titration upward as needed, depending on the patient's response and any adverse reactions they may experience. If necessary, the dosage may be adjusted by increments based on the efficacy and tolerability observed during treatment. Higher starting doses could lead to a higher incidence of side effects and toxicity, making the 40 mg starting point an important aspect of safe clinical practice for managing essential tremor with Propranolol.
