Abstract
The effect of Periactin, an antihistaminic and antiserotonic agent, against nasal allergy has been studied.
The agent was given orally 4-12mg for 7-21 days.
It was effective for the typical symptoms of sneezing, itching and nasal discharge but showed little efficacy for nasal stuffiness.
This drug showed no side effect except slight sleepiness in 5 out of 40 cases.
It has been found that Periactin is clinically useful for nasal allergy.
