Probably allergic: and don't see a reason that stopping chewing tobacco (congratulations and STAY QUIT) would do this. Multiple sneezing is usually allergic. The use of one of the newer selective and less-sedating antihistamines (Claritin, Zyrtec etc) should be safe (check with pharmacist if you are on other meds) and reduce your sneezing. If it doesn't, see your primary care provider. ...Read more

Which medications should I stop before the allergy test. And for how long should I stop them is it three days or 1 week is vitamins ok to take?

Antihistamines: Vitamins are ok. Primarily it is antihistamines that are the issue, and need to be avoided for a week prior to the test. Some for 5 days, depends on the allergist and the method of testing. Beware of antihistamines now in nasal sprays and eyedrops. Plus certain pysch drugs (notably antidepressants). Tests should include + and - control tests; + control doesn't show positive? Problem. ...Read more
