Almost three in four U.S. allergy specialists are prescribing tablets to ease symptoms caused by pollen, ragweed and dust at least some of the time, though they have not completely shifted away from allergy shots, a survey suggests.
The upside of allergy shots, available for more than a century, is they can be formulated to treat more than one allergy. But they are not always appealing to patients because they require multiple office visits to administer. Recently-introduced tablets dissolve under the tongue and can generally be taken at home, but can only target one allergen at a time.
