I'm about to start a trial run with IPT-141 and need to know if there is any adverse reactions with antihistamines or decongestants. I'm 63, 195 lbs and have had sinus problems all my life. Went to an allergist and they pricked my arm in about 75 places. It looked like an airport landing strip with all the red bumps on it. Doc came in and said I was lucky. I'm like what? He continued, Your only allergic to three thing. What??? Spring, summer and fall. So I am on pseudoephedrine and cetirizine HCI on a daily bases. Does anyone know if they are going to interfere with the PT-141. Thanks
