Can Histal Take During Medication

Is histal dc available in the U.S.?

During airplane decents prior to landings, I suffer with excruciating pain in my ears. While traveling abroad, I was issued histal dc. In short, l was able to fly without the usual discomfort. Is histal dc sold in the U.S. i have not been able to find it. Do i need a prescription? ## Hello, Chanel! How are you? I can't find a listing for Histal-DC. Do you happen to know what the ingredients are?
