What can i do for allergies?

Antihistamines: You can try over the counter antihistamines such as Claritin or zyrtec or Benadryl (diphenhydramine) for relief. You may wish to have an allergy panel performed to see what things you are allergic to, as decreasing your exposure to them is part of the treatment plan. Sometimes just by changing carpeting or putting covers on pillows or mattress or decreasing exposure to things, you don't even need medications.

Claritin (loratadine): Otc antihistamines like claritin, zyrtec, allegra, or Benadryl (diphenhydramine) should help.

Broad Answer: This is a very broad question and the answer will depend upon what you mean by "allergies". If you suspect you have allergy you should see your pcp for guidance. If that is not helpful or their suggestions are not providing relief then consider seeing a board certified allergist for their opinion.

If your symptoms are severe or recur frequently then allergy testing may be beneficial. Environmental modification is also an essential part of treatment.
