Yes w/Allergy shots: The approach to treat allergies is three-fold: avoid the offending allergen if possible (easiest for indoor allergens like pet dander); medications (like antihistamines & nasal sprays); and immunotherapy (shots) that decrease your body's sensitivity to airborne allergy provokers. When the first 2 approaches don't work or medicines cause side effects, shots are the best way to improve allergies. ...Read more
Timing: Antihistamines work by blocking histamine receptors in your body. If the receptors are all full of histamine already (reaction has occurred), then there is nowhere for them to go and it will not make a difference in allergy symptoms. If you take them before exposure to allergens they can block the receptors and you will have less symptoms. ...Read more

Everyday all day im always itching. I take a allergy pill everyday but still itching all the time?
Chronic itching: Many times there is not a specific cause, like a food allergy, that we can find for itching, and we have to try different antihistamines in different doses to get relief. Zyrtec 10 and Allegra 180 usually work better than Claritin (loratadine) for itch, and it is safe to use at least 1 twice a day. Itching can be a symptom of a more serious medical condition, so see a doctor for tests if you haven't yet. ...Read more

I took a 24 hr allergy pill at 9am. I did very labor intensive yard work for 8 hrs. It is now 10pm and all symptoms are back. Can I take another pill?
If I took an allergy pill (extra strength 1aday) at 2pm yesterday, it is 7:00 am and I am needing another, can I take now? At work have allergy to cats.
Depends: It is occasionally ok to take extra dose of antihistamine but if you are taking 24 hour antihistamine decongestant combination it would be too much decongestant. Check with your doctor for other medicines that might relieve your symptoms. If you have unavoidable cat exposure you may benefit from a visit to the allergist. ...Read more
