My daughter and I go through bad allergies.
For starters, right now we are taking Allegra. When we finish that bottle (large bottle from Costco), per the Dr., we will switch to Claritin, and rotate each bottle.
The Dr. said you can get immune to the allergy med so to switch it up.
We also do the nasal rinse which helps a lot.
This one sounds weird but it works... The Dr. said to gargle at least twice a day with Listerine. It loosens up the junk in your throat. I also helps stop the coughing if you have the cough.
Lastly, sprinkle local bee pollen on your food or just take about 1/2 teaspoon daily. Local honey works too, the bee pollen is just more concentrated. It does not taste that bad, I just pop it in my mouth and wash it down with juice.
We have to be diligent to take the meds daily. We take the 24 hr pill. Sometimes when it is really bad, benedryl at night is the only way I can sleep.
