First non sedating antihistamine
Another advantage of the newer antihistamines is that they're available in time-release versions.
That means you can control your symptoms with only 1 or 2 doses each day compared with older medications, which usually require doses every 4 to 6 hours to maintain their effectiveness.
The question, is it necessary to spend the extra money?
" These newer products, which include Allegra, Zyrtec, and Claritin, generally cost between 10 to 20 times as much as the older, "first-generation" products.
The people who were intoxicated drove as though they were.
And the people who took Benadryl looked normal, but drove like the drunks," says Steven H.
There is little evidence that antihistamines used symptomatically to treat nonspecific itching have any effect greater than placebo.
"Today, most people would lead to nonsedating medications." And perhaps with good reason: Some 35 states in the U. have laws related to driving while impaired -- not only by alcohol, but also from antihistamines, says Cohen. "Zyrtec is a relatively non-sedating antihistamine, but it has a warning in the Physician's Desk Reference [which gives detailed information on prescribing drugs] about operating machinery when taking it," he tells Web MD.
You may have taken antihistamines in the past and found it hard to concentrate or stay awake.
Still, Cohen says what makes it important is that it had patients perform a technical skill that requires optimal alertness.
"And based on that study, I certainly wouldn't have wanted to face those Benadryl people on the road." In Bender's analysis, some studies involved self-reported levels of sedation, while others measured their ability to perform specific tasks.
