Depends on the allergy condition and depends on the medication. If you're having hay fever, an allergic reaction to the pollen out there, if you start taking your medication now, you can expect prompt relief. By that I mean within hours with antihistamines and decongestants, and within days with the inhaled nasal cortico steroids. If you have a more complex problem, if you have asthma, again, one would expect prompt relief, but the prompt relief would be measured in days to weeks rather than hours to days.
