While it’s true that sometimes drugs become less effective after you take them for a long period of time, in many cases just changing the type of medication and when you take it can help.
Oral antihistamines work much better if you take them in anticipation of exposure to allergens rather than after -- so if someone has recurring seasonal allergies, I recommend that they use these medications on a preventive basis. Also, sometimes switching to a different brand of oral antihistamine might make a difference. These products can cause drowsiness, but not everyone develops the same degree of fatigue.
Nasal decongestant sprays work very well, but you should use them only as directed: twice a day for no more than seven consecutive days of treatment.
Keep in mind that sometimes allergies get to the point where OTC medications aren't enough and prescription drugs are necessary. Talk to your doctor to figure out what’s best for you.
