New research shows that allergens are the top three most common drugs used in the United States.

In fact, they’re the most common drug in almost all states and are also used to treat asthma, eczema, and allergies in the U.S. That makes them particularly important for treating the chronic and acute symptoms of allergic diseases.

The top three allergens on the list include echinacea, hay fever, and staphylococcus aureus (a common bacteria that can cause severe allergic reactions).

They are also among the top 15 most commonly prescribed medications, according to the report, which is based on data from the U-M Food and Drug Administration and the Drug Enforcement Administration.

The report found that the most commonly used drugs in the country are allergen drugs, such as aseptic, non-steroidal anti-inflammatory drugs (NSAIDs), antihistamines, and antifungals.

They account for almost 40 percent of all prescribed drugs in each state.

The second most common class of medications, the least commonly used, is steroid drugs.

These include testosterone, diuretics, and antihistamine agents.

The top 10 drugs most commonly administered to patients with chronic, acute, or recurrent allergies are also the top 25 drugs most frequently used to manage the symptoms of asthma, which can be caused by anaphylaxis, the report said.

There’s no clear relationship between allergies and use of prescription drugs.

But some people with allergies may be more likely to use drugs that can help them manage their allergies.

People who use more than 10 medications for the same condition have higher rates of use of medications that help them control their symptoms, according the report.

That’s a trend that researchers say may be due to the fact that allergies are not seen as a chronic disease.

“The fact that the top five allergens account for over half of the prescription medications prescribed in the US is a reflection of the number of medications being prescribed,” said Dr. William L. Jones, a physician and allergist in the Division of Allergy and Immunology at U-Mass Medical School in Worcester, Massachusetts.

“This shows how much of an impact the allergens have on the lives of people with these conditions.”
