"I&#039;ve found this product helps to shrink the nasal passages to relieve some of the pressure, but not the headache the build up causes.  They should consider including acetometophine (sp?) for the PAIN that the built up pressure can cause.  In addition to taking the Alavert-D, I have to also take 2 Tylenol for the pain in order to get relief.  Even with taking the Alavert-D and the pressure being released, the pain does not subside unless I take something for it."
