Question
How is guaifenesin treatment for facial palsy? I have a friend who has lost expression, and later found out it was caused by guaifenesin. How should guaifenesin-induced facial palsy be treated?
Answer
Guaifenesin has certain nerve-nourishing effects and may have some efficacy in treating facial palsy caused by nerve damage. However, this type of damage is not substantial and has some reversibility, so medication treatment can be considered in such cases. Facial palsy is often caused by facial neuritis, so medication treatment can be administered. Wishing you good health.
