What are beta-blockers for essential tremor?

ANSWER

The beta-blocker propranolol (Inderal) has been used to treat essential tremor for more than 40 years. Other beta-blockers such as Lopressor also may be effective.

It's not clear how Inderal cuts tremors, but the drug may work by blocking nerve impulses to the muscles. Approximately 50%-60% of people taking Inderal have some improvement in function. The greatest improvement is in hand and voice tremors.
