Non sedating antihistamine drug list
Most of the studies reviewed used doses that were twice the recommended amount -- 50 milligrams -- of diphenhydramine, the active ingredient in Benadryl and other first-generation "sedating" allergy medications.
"We're not saying that there's not a difference," says lead researcher Bruce G.
Most of the second-generation antihistamines have been shown to benefit chronic idiopathic urticaria.
Once-daily fexofenadine appears to offer effective and well-tolerated relief from the symptoms of this illness.
This includes conditions such as: Other conditions such as hyper-reactive (vasomotor) rhinitis and pruritus of any cause are commonly treated with antihistamines, although there is little evidence that histamine plays a contributory role.
There is little evidence that antihistamines used symptomatically to treat nonspecific itching have any effect greater than placebo.
The question, is it necessary to spend the extra money?
"In some studies we reviewed, some people actually experienced more sedation with the newer, nonsedating formulas than with the older, sedating products.
It may be used as a combination with a beta 2 agonist as in the case of combivent (albuterol and ipratropium).
However persistent asthma should be treated with a controller drug such as inhaled steroid and/or a leukotriene blocker.
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.
