For Allergic Rhinitis "I occasionally get severe sneezing attacks, cause unknown. They start as a feeling like something tickling my nose followed by a deep intake of breath and a powerful (mostly dry) sneeze. This then repeats about every 20 seconds for several minutes, when it stops, leaving me exhausted and with teary eyes and a runny nose. I found that swallowing a short-acting chlorpheniramine maleate tablet at the first sign, or in between sneezes, is effective at immediately stopping the attack, with no noticeable side effects. I have other chronic health conditions for which I take prescription medications; long term use of antihistamines for me is not recommended."
